Dell PowerEdge M820 blades: Balancing performance, density, and high availabi...Principled Technologies
Finding a server that can deliver the right balance of high workload performance, density, and RAS features can help you meet both infrastructure and business goals at the same time.
In our tests, the single-width Dell PowerEdge M820 blade delivered 19.3 percent better Oracle Database 12c performance than the HP ProLiant BL680c G7 in half the space, meaning it could deliver 2.38 times more transactions per U. The value of the denser Dell PowerEdge M820 was clear in our cost analysis of the two systems. Because the Dell PowerEdge M820 takes up less space, you need fewer enclosures, less rack space, and can save on port costs. In our sample comparison of two performance-equivalent solutions, we found that the Dell PowerEdge M820 solution could save up to 42.1 percent compared to an HP ProLiant BL680c G7 solution. That’s money that you can use to buy even more servers for greater performance or to innovate elsewhere. We also found that the Dell PowerEdge M820 took high availability into account by utilizing key RAS features to help increase your workload uptime.
If you’re looking for a dense blade solution to lower costs with the power to handle your important workloads and keep them running, our study shows that the Dell PowerEdge M820 blade addresses all those concerns.
The Dell OpenManage Enterprise Power Manager 3.0 plug-in provides sustainability insights through automated data collection and reporting. It tracks power usage metrics, identifies idle servers, estimates carbon emissions, and detects devices exceeding power thresholds - helping optimize infrastructure utilization and reduce energy costs and carbon footprint. The plug-in interfaces all functionality through a single console for improved visibility and workload management.
This document discusses Intel's Intelligent Power Node Manager solution for managing power usage in data centers. It notes that power and cooling costs are a major challenge as data needs increase exponentially. The Power Node Manager allows data center managers to set a power budget or "cap" for each server to better utilize existing power capacity and increase compute density. It provides real-time power monitoring and enables power capping to maintain performance within the set limit or adjust if the limit is exceeded. This allows data centers to squeeze more performance from their existing power infrastructure.
Systems management savings with Dell OpenManage on 13G Dell PowerEdge servers Principled Technologies
Administrators can spend their time doing routine tasks such as firmware updates, or they can spend their time on other initiatives to make your data center and your business more successful. Older servers keep admins focused on routine tasks instead of innovation because they just don’t have the capabilities to streamline management in a meaningful way to lessen the burden of routine management tasks.
In our hands-on tests, we found that Dell PowerEdge R730 servers with Dell OpenManage dramatically reduced the time it took to deploy, update, monitor, and maintain servers compared to completing the tasks manually on older systems. We estimate that you could save as much as 91.3 percent of administrator time—nearly 800 hours—over two years for a 200-server deployment.
Don’t let your older servers continue to be a time sink for administrators. By upgrading to new Dell PowerEdge R730 servers with new systems management features to handle routine tasks, you can potentially redirect those resources to innovation in other areas.
Using Lenovo ThinkServer Smart Grid Technology with Intel Node Manager Technology allows you to plan, observe, and manage your power utilization on Lenovo servers. In processor-intensive workloads, you can lower power and achieve increased performance per watt for maximum efficiency. In IO-intensive workloads, where unused processor utilization exists, you can increase server density per rack (per unit power) and recoup unused power without significantly affecting overall performance. These and the other features of Lenovo ThinkServer Smart Grid Technology offer new flexible and powerful ways for administrators to manage data center power usage and control costs.

Principled Technologies testing showed that a 16th Generation Dell PowerEdge R760 server featuring a Broadcom BCM57508-P2100G NIC delivered all three vs. previous‑generation PowerEdge servers
Conclusion
Organizations don’t have to choose between saving money, doing more work, and using less energy; the new 16th Generation Dell PowerEdge R760 servers with Broadcom NICs do all three. In our hands-on testing, the new 16th Generation Dell PowerEdge R760 server featuring a Broadcom NIC offered 166.1 percent more Ops/s per US dollar, 129.5 percent more Ops/s, and 24.2 percent better performance per watt than the 14th Generation Dell PowerEdge R740 server. This means the PowerEdge R760 with a Broadcom NIC did over twice as much work at a lower cost with nearly 25 percent better power efficiency than the PowerEdge R740. When compared to the 15th Generation Dell PowerEdge R750, the PowerEdge R760 processed 29.8 percent more Ops/s at a lower cost in terms of Ops/s per US dollar and offered 3.8 percent better performance per watt.
In addition to lowering cooling costs and carbon emissions, choosing the latest-generation servers can help businesses lower other operating costs, such as maintenance and security compliance. Because the latest-generation Dell PowerEdge R760 servers offer more compute capacity, fewer servers can do more work, potentially reducing licensing costs and the physical footprint of a data center. Newer servers often feature the most recent manageability and security features, which can make it easier for businesses to manage their servers and protect their data. By choosing servers with better performance, businesses can reduce the response time of their systems and provide a better user experience.
Increasingly, businesses are under pressure to reduce the energy consumption and cost of their data centers while maintaining or increasing performance. Key web technologies such as Redis can offer businesses a competitive edge, but they also require a large amount of data processing. Businesses can meet these challenges with Dell PowerEdge R760 servers with Broadcom NICs that offer better costefficiency, performance, and power-efficiency.
This document discusses ways to improve data center efficiency. It notes that data centers currently consume 1.5-2.2% of global power usage. Improving efficiency can save electricity and costs. Metrics like PUE measure efficiency by comparing total energy use to IT equipment energy use. Google achieved a PUE of 1.16 through innovations like integrated server UPS batteries and optimized cooling. The document outlines various hardware, software, and operational strategies data centers can use to improve efficiency, such as virtualization, lean operating systems, storage optimization, and intelligent workload scheduling.
This document discusses how to design data centers for maximum energy efficiency. It identifies the main culprits of inefficiency as power equipment, cooling equipment, lighting, oversized equipment, and poor configuration. It recommends 8 characteristics of highly efficient data centers, including using scalable power and cooling, row-based cooling, high-efficiency UPS, high voltage distribution, variable speed drives, capacity management tools, and room layout tools. The document outlines 7 key elements of efficient data center design that incorporate these characteristics and can save up to 40% on energy costs.
This document summarizes the key steps in calculating power and cost savings from virtualizing servers. It discusses identifying needs and developing a baseline by measuring current hardware usage. It then covers calculating power savings based on virtual infrastructure configurations and average wattages. Finally, it outlines how to determine total cost of ownership savings from reductions in hardware, facilities, support and other expenses. The overall goal is to demonstrate savings across multiple stakeholder groups from customers to C-level executives to operations managers to end users.

Increase security, sustainability, and efficiency with robust Dell server man...Principled Technologies
Compared to the Supermicro management portfolio
Conclusion
Choosing a vendor for server purchases is about more than just the hardware platform. Decision-makers must also consider more long-term concerns, including system/data security, energy efficiency, and ease of management. These concerns make the systems management tools a vendor offers as important as the hardware.
We investigated the features and capabilities of server management tools from Dell and Supermicro, comparing Dell iDRAC9 against Supermicro IPMI for embedded server management and Dell OpenManage Enterprise and CloudIQ against Supermicro Server Manager for one-to-many device and console management and monitoring. We found that the Dell management tools provided more comprehensive security, sustainability, and management/monitoring features and capabilities than Supermicro servers did. In addition, Dell tools automated more tasks to ease server management, resulting in significant time savings for administrators versus having to do the same tasks manually with Supermicro tools.
When making a server purchase, a vendor’s associated management products are critical to protect data, support a more sustainable environment, and to ease the maintenance of systems. Our tests and research showed that the Dell management portfolio for PowerEdge servers offered more features to help organizations meet these goals than the comparable Supermicro management products.
Intel Intelligent Power Node Manager is a server power management system that reports actual power usage and caps power usage to maximize efficiency. It allows data center managers to set power budgets for servers to enable up to 20% more dense deployments. When paired with Intel Data Center Manager, it can help optimize entire data centers by monitoring individual server power consumption and temperatures to link cooling to actual power demand.

For your data center to keep pace with the growth of your business, your database servers must be able to run as many VMs as possible with the lowest amount of power per unit of performance, and do so in the smallest amount of rack space. If you have a collection of aging servers taking up too much space and using too much power in your data center, consider consolidating them into the NEC Express5800/A2040b server powered by the Intel Xeon processor E7-4890 v2. Based on our findings, a single NEC Express5800/A2040b can replace nine HP ProLiant DL385 G6 legacy servers with VMs running heavy database workloads. This means the NEC Express5800/A2040b server can deliver similar VM database performance while using 77.8 percent less rack space, freeing up your data center space for future growth and potentially saving you from costly infrastructure expansions. What’s more, the NEC Express5800/A2040b server delivered 57.0 percent power savings while running the same workload as the legacy server, which resulted in 123.7 percent better performance per watt. The added power efficiency can save your business in recurring power and cooling costs of your data center. These advantages, combined with steady performance, make the NEC Express5800/A2040b server a wise choice for your data center.
As our tests show, investing in the powerful new Dell PowerEdge R920 running Oracle VM Server 3.2.8 with Oracle Database 12c VMs achieves cost savings without compromising performance. In our testing, a single Dell PowerEdge R920 could perform five times the work of a single HP ProLiant DL385 G6 server; the costs to power and cool the Dell PowerEdge would be 43 percent less than the five servers it could replace. The three-year software licensing costs of the Dell PowerEdge R920 server would be 22 percent lower than the licensing costs for the five-server solution. These dramatic savings—which come out to $212,091 for our single test environment — could grow to millions of dollars in a larger consolidation effort.
The Dell PowerEdge R410 and PowerEdge T410 servers are 11th-generation Dell PowerEdge servers designed to meet the needs of small and medium businesses in a cost-effective way. They are comprehensively tested to help ensure compliance with stringent 11th-generation PowerEdge server standards for electrical, mechanical, thermal, and acoustic design. Base configurations include cost-optimized components like cabled power supplies and hard drives, while more advanced features are available as optional upgrades. This allows the servers to provide high performance suitable for SMB needs at an affordable price.

Competitive Analysis Dell Open Manage Power Center vs IBM Active Energy Manager
1. A PRINCIPLED TECHNOLOGIES TEST REPORT
Commissioned by Dell Inc.; October 2012
SERVER POWER MANAGEMENT COMPARISON: DELL OPENMANAGE
POWER CENTER AND IBM SYSTEMS DIRECTOR ACTIVE ENERGY MANAGER
In your data center, you need both strong and continuous performance to handle the
needs of your employees and customers, and advanced management technologies to keep
operational expenses down. High among these operational expenses are the power costs related
to running and cooling your servers.
We tested two applications—Dell OpenManage Power Center managing a Dell
PowerEdge R720 server and IBM® Systems Director Active Energy Manager, an IBM Systems
Director plug-in, managing an IBM System x3650 M4 server—with the goal of understanding the
ways that their respective power management tools affect performance and power usage in the
data center. We focused on the tools’ approaches to setting power limits, also known as power
capping.
In our tests, the Dell OpenManage Power Center provided more precise power limiting
than IBM Active Energy Manager. The difference between the actual power used by the Dell
solution and the power limit we set was 2 percent or less, versus a difference of 4 to 8 percent
with the IBM solution. The smaller gap lets administrators maximize the number of servers that
can fit within the data center’s total power capacity. Increasing data center density in this way
saves money. Dell OpenManage Power Center also offered greater management flexibility out of
the box, including the ability to easily set priorities among servers and to initiate an emergency
power response.
The Dell PowerEdge R720 also offered greater performance per watt and supports a
much higher working temperature, through the Dell Fresh Air initiative, than the IBM System
x3650 M4. These energy-saving features can lead to significant data center energy cost savings
for your enterprise.
2. A Principled Technologies test report 2Server power management comparison: Dell OpenManage Power
Center and IBM Systems Director Active Energy Manager
THE POWER OF POWER LIMITS
One of the biggest sources of return from an investment in the latest equipment
and management software is being able to take advantage of new power-saving
technologies. In the typical server, power utilization increases as the server load
increases. Being able to limit or cap the amount of power a server or group of servers
consumes offers great flexibility, often without decreasing performance.
Power management tools let you as the administrator set power limits at the
data center, room, aisle, rack, or server level. You can also set different power limits for
different times. For example, you can give a server a lower power limit in the evenings,
when less work is taking place, and a higher limit during the day, when greater
performance is needed. Being able to set these limits can dramatically boost data center
rack density as you can now safely add extra servers to the same circuit without fear of
tripping the breaker.
Two approaches to power management: Dell OpenManage Power Center and IBM Active
Energy Manager
Dell OpenManage Power Center, using Intel Node Manager Technology, lets IT
administrators look at the data center power usage. Power Center is an open,
standards-based power management application that can read power usage
information from Dell PowerEdge servers, power distribution units, uninterruptable
power supplies, or Dell PowerEdge blade server chassis.
As an IT administrator, you know that you can only manage power utilization if
you can collect data related to it. OpenManage Power Center offers many advanced
features for monitoring your data center power utilization. You can view instantaneous
power usage or temperature and examine power usage over specific time increments
(15 minutes, 1 hour, 1 day, 1 week, 1 month, 3 months, or 1 year). OpenManage Power
Center shows peak, average, and minimum power across the data center, room, aisle,
rack, or server. Understanding your power utilization opens a wide range of
opportunities for server density, power savings, and uptime improvements.

http://www.dell.com/us/enterprise/p/dell-openmanage-power-center/pd, or see an
additional report from Principled Technologies, at:
http://www.principledtechnologies.com/clients/reports/Dell/R720_power_0312.pdf
According to the IBM Web site, “IBM Systems Director Active Energy Manager is
an IBM Systems Director plug-in. Use Active Energy Manager to monitor and manage
the power and cooling needs of IBM servers and BladeCenter® systems. Non-IBM
systems can also be monitored using metering products, such as power distribution
units (PDU), sensors, and integration with facility software.
3. A Principled Technologies test report 3Server power management comparison: Dell OpenManage Power
Center and IBM Systems Director Active Energy Manager
“The tasks you can perform on Active Energy Manager resources include the
following: monitoring and collecting power consumption data; managing power, which
includes setting power savings options and power caps and automating power-related
tasks; configuring metering devices, such as PDUs and sensors; exporting data; viewing
events; calculating energy cost; setting thresholds; creating and setting power policies;
and monitoring power and cooling equipment that affect IT resources.”

http://pic.dhe.ibm.com/infocenter/director/v6r1x/index.jsp?topic=/aem_420/fr
b0_main.html.
For testing, we applied the power caps on the input power. This worked fine on
the Dell PowerEdge R720 out of the box. However, the IBM System x3650 M4 did not
cap the input power correctly. We worked with IBM support and applied a patch to get
this feature working correctly. A Technote showing this patch is available at
http://www-01.ibm.com/support/
docview.wss?rs=0&q1=eServerOnDemandKBRCH&q2=649755169&uid=nas7d686520ea

WHAT WE FOUND
When looking at a power management solution, it is important to understand
how the application lets you set power limits for optimum data center and system
management. Dell OpenManage Power Center and IBM Active Energy Manager handle
power limiting differently, with the main difference being the size of the gap between
the intended power limit and the actual power usage.
To understand this difference and its importance, you must first understand
what these two numbers mean. The intended power limit is the setting you enter in the
management software as a level not to be exceeded. For example, an intended limit of
80 percent means the server should never use more than 80 percent of its maximum
capacity at any time. The actual power limit is the amount of power the server actually
uses. Note that the actual power limit average should always be below the intended
limit.
To illustrate the difference between these two levels, we present graphs of both
systems’ actual power usage under two conditions: when we set the intended power
limit to 80 percent of their total power and when we set no power limit. We used a Dell
PowerEdge R720 with Dell OpenManage Power Center and an IBM System x3650 M4
with the IBM Active Energy Manager for this evaluation. Because the two servers have
different power draws, the intended limits of the two servers differ accordingly. We
chose this approach to avoid unfairly penalizing either of the servers by setting an
identical limit on both systems.
4. A Principled Technologies test report 4Server power management comparison: Dell OpenManage Power
Center and IBM Systems Director Active Energy Manager
Figure 1 shows the power usage at 1-second intervals over a 2-minute period
for the Dell PowerEdge R720 with an 80 percent power limit of 304 watts and with no
power limit. (Note: To magnify the power variations during the run, we do not start the
vertical axis of the chart at zero.) As Figure 1 shows, with the 304-watt intended limit,
actual power usage of the Dell PowerEdge R720 averaged slightly over 302 watts. While
it did reach the 304-watt limit, it never went over. The maximum difference between
the intended 80 percent of faceplate power (304 watts) and the actual power limit was
2 percent.

PowerEdge R720 with an

Figure 2 shows the power usage at 1-second intervals over a 2-minute period
for the IBM System x3650 M4 with a 325-watt power limit and with no power limit. (As
in Figure 1, to magnify the power variations during the run, we do not start the vertical
axis of the chart at zero.) As Figure 2 shows, with the 325-watt intended limit, actual
power usage averaged around 310 watts, roughly 5 percent lower than intended power
limit.
While a larger difference between the intended and actual power limit does
guarantee that the power will not exceed the set limit, it also means that you cannot
configure a server rack as densely. For example, 20 servers with a 325-watt power limit
would be a total of 6,500 watts, while the actual power used would be 6,200 watts. This
means that 300 watts are allocated but unused. In this example, if the percentage
difference between the intended limit and actual power were closer, as with the Dell
PowerEdge R720, you could essentially put another server in the rack using the same
total power limit.

The impact of power limiting
In addition to evaluating how both applications handle power limiting, we also
looked at the performance-per-watt advantages of the new Dell PowerEdge R720 server
at different power levels compared to the IBM System x3650 M4 server.
To test the performance per watt, we used DVD Store 2.1 (DS2), which reports
performance in orders per minute (OPM), running Microsoft SQL Server 2008 R2 with
6GB databases on both servers. For this workload testing, we used four SQL database
instances with two DVD Store databases. We used one client for each database for a
total of eight clients. (For details about that workload, see Appendix C.) Figure 3 shows
the results from our test.
As Figure 3 shows, running the PowerEdge R720 at as much as a 40 percent
power reduction provides performance-per-watt advantages over the IBM System
x3650 M4. In fact, running the PowerEdge R720 with a 30 percent power reduction
provides the highest performance-per-watt advantage. One practical application of the
data is with CPU-intensive nightly batch jobs, where it does not matter if the job takes a
few more minutes. Our findings show that you could run most efficiently if you limited
the power at 70 percent.

Center and IBM Systems Director Active Energy Manager
DELL OPENMANAGE KEY FEATURES
Dell OpenManage offers several key features to help manage your data center
to ensure server uptime and utilize power in the best way possible. We explain these
features in the section below.
Reliability during a power outage
Data center servers must stay up and available for users. Dell OpenManage
Power Center offers a feature to reduce power in the event of an emergency such as
drop in data center power or cooling.
Dell OpenManage has an option called Emergency Power Reduction (EPR). The
administrator can initiate EPR by simply clicking a button in the management console to
initiate the power reduction. This feature is available at all levels from the data center
down to an individual server, which enables administrators to be extremely precise in
selecting what to slow down.
To test the EPR feature, we ran a database workload using 100 percent
processor utilization on the Dell PowerEdge R720 while running on battery backup. First,
we ran the server with no power limits. We then repeated the test after selecting the
EPR option.
As Figure 5 shows, the Dell PowerEdge R720 ran longer with the emergency
power reduction feature enabled. While in EPR mode, the PowerEdge R720 is able to
run nearly four times as long, maximizing up time during a power outage.
Figure 5: Running on battery
backup with the emergency power
reduction feature enabled let the
Dell PowerEdge R720 run much
longer. 11

IBM Active Energy Manager provides options for an administrator to set up a
group policy with power capping in the event of a power change, but the setup requires
many more steps. In addition, administrators must set the static power caps in advance
8. A Principled Technologies test report 8Server power management comparison: Dell OpenManage Power
Center and IBM Systems Director Active Energy Manager
of an emergency power event. We did not test the IBM emergency feature as a
comparison since there is no predefined emergency power feature on the IBM as with
Dell OpenManage. We found Dell OpenManage’s EPR simpler to initiate in the event of
a power failure.
Power limit response time
Because Dell OpenManage Power Center offers a low percentage difference
between the intended and actual limit, it is important for the software to react quickly
in the event that the power demand exceeds the intended limit. This fast reaction time
allows administrators to increase the server density on circuits without fear of
overloading. To test this feature, we implemented a power limit of 225 watts on the
server and then began the database workload. As the workload ran, the server power
increased up to the 225-watt limit. Figure 6 shows that within 300 milliseconds of going
over the power limit, the power came back down and stayed within 1 percent of the
power limit. (Note: To magnify the power variations during the run, we do not start the
vertical axis of the chart at zero.)
Figure 6: When power
usage on the Dell
PowerEdge R720

came back down in less
than half a second. (To

Another major advantage of the Dell PowerEdge R720 server over the IBM
System x3650 M4 server is its ability to operate at much higher temperatures. Through
the Dell Fresh Air initiative, Dell servers are now rated to operate at up to 113 degrees
Fahrenheit, allowing data centers to save substantially on cooling costs.1

specifications for the IBM System x3650 M42
indicate that it supports operation at up to
104 degrees.
For most data center managers, the best approach will be to examine
temperature and usage patterns to determine the “sweet spot” where the data center is
providing the highest possible energy savings. For more information on the Dell Fresh
Air initiative, see www.dell.com/freshair.
Implementing server priority on the Dell PowerEdge R720
When using power limiting, it is important to provide proper server
performance to your applications. OpenManage Power Center offers the ability to set a
dynamic limit and to set priorities at the room, aisle, or server rack levels. When
applying the dynamic limit, you specify a priority of high, medium, or low for each group
based on its performance and power needs. For example, if applying a dynamic limit on
a server rack, you specify which servers are higher or lower priority.
To test this feature, we used the SPECjbb®2005 benchmark3
to apply a constant
workload on three servers in a rack. We ran each server at 100 percent CPU utilization.
The three Dell PowerEdge R720 servers consumed approximately 1,150 total watts. We
set a dynamic limit of 850 watts and gave each server a different priority—one high, one
medium, and one low. As Figure 7 shows, total power usage dropped precipitously
when the limit was applied, and the usage of the three servers varied according to their
priority.
We then stopped the workload on the high-priority server. Once OpenManage
Power Center identified available watts for the medium- and low-priority servers, they
were allowed to consume more power up to the limit of 850 total watts.

The server priority feature is included with Dell OpenManage Power Center and
works automatically with your existing power distribution units (PDU), so other than the
purchase of the Dell PowerEdge servers, no special hardware is required.
While IBM Active Energy Manager provides the option to set group power
capping it does not have the ability to set priorities, but rather divides the allotted
power by the number of systems. This approach leaves power unutilized. For example,
in our testing we applied a 500-watt power cap on a group of two servers. When
running equal workloads, both servers used 250 watts of power. However, when we
stopped the workload on one server, the power draw dropped to the 110-watt idle
power level, while the other server continued to use only 250 watts of power. This left
140 watts of power unused. In the Dell OpenManage approach, the 140 watts of power
would be made available to the other server.
CONCLUSION
As data centers grow, their power needs increase and space becomes more and
more of a premium. These rising costs make it essential to manage your data center as
effectively as possible.
Using Dell OpenManage Power Center with Intel Node Manager Technology in
conjunction with the latest Dell PowerEdge servers offers a completely new approach to
data center power usage. Dell OpenManage Power Center allows managers to collect,
observe, and optimize power utilization to increase uptime and make better power-
usage decisions.
In our testing, we saw a gap of only 2 percent between actual usage and the
intended power limit; this small difference can let you fit more servers into your data
center without exceeding your total available power. While implementing power limits,
11. A Principled Technologies test report 11Server power management comparison: Dell OpenManage Power
Center and IBM Systems Director Active Energy Manager
the Dell PowerEdge R720 maintained consistent performance and delivered up to 7.5
percent more performance per watt than the IBM System x3650 M4 managed by IBM
Active Energy Manager.
Dell OpenManage Power Center features extended operation time by almost
four times using battery backup with their Emergency Power Reduction feature and
permitted us to implement server prioritizing.
In addition, through the Dell Fresh Air initiative the latest Dell PowerEdge R720
servers allow you to run at higher temperatures—up to 113 degrees—which can lead to
significant data center cost savings.
Overall, the Dell OpenManage Power Center gives data center managers greater
confidence and control over server power usage, which leads to an efficient, optimized
data center with significant cost savings.

APPENDIX C – DATABASE WORKLOAD
To build the workload, we used DVD Store Version 2.1 (DS2), an open-source simulation of an online e-
commerce DVD store. DS2 has database components and Web server components, and includes driver programs that
place heavy loads on these components. A new feature of DVD Store Version 2.1 uses the ability to target multiple
databases from one source client. We used this functionality to record the orders per minute output from each specific
database target.
The Dell PowerEdge R720 and IBM System x3650 M4 ran four Microsoft SQL Server 2008 R2 instances, with two
6GB databases per instance for the 100 percent processor utilization testing.
The main DS2 metric is orders per minute, which the driver program calculates and records to a text file on the
client machines. The DVD Store client application outputs OPM at 10-second intervals. We ran this workload on the
server for 30 minutes and report the last OPM score the benchmark reported.
A DS2 order consists of a customer login; a search for movies by title, actor, or category; and a purchase. The
workload also performs other actions, such as adding new customers, to exercise a wide range of database functions.
As we note above, because our goal was to isolate and test database server performance, we did not use the
front-end Web client component of DS2. Instead, we ran a compiled driver on client machines via its command-line
interface. We used the default DS2 parameters and setup configuration, with the exceptions we note in the Setting up
DVD Store version 2.1 sections below.
We used eight client machines with one client connecting to each of the eight databases. Each client machine
ran a single instance of DS2, with 16 threads to simulate a heavily loaded environment; the load-generating client
machines used a 5 percent new customer setting and ran with no think time, processing requests as quickly as the
servers were able.
For more details about the DS2 tool, see http://www.delltechcenter.com/page/DVD+Store.
Setting up the servers for DVD Store
Our DVD Store test bed consisted of a Dell PowerEdge R720 or IBM System x3650 M4 as the server under test
and eight Intel-based clients. Each client had an Intel Pentium 4 3.00GHz processor, 1 GB of system memory, and a
Gigabit network card in default configurations. We connected the systems via one Gigabit network switch. We installed
a fresh copy of Windows Server 2008 R2 Enterprise Edition on the server.

12. In the right pane, right-click SQL Server (MSSQLSERVER), and select Restart from the drop-down menu.
13. Repeat step 12 for the remaining three SQL Server instances.
Installing and configuring the database clients
For the DS2 scripts, we used eight clients to simulate a number of users putting a load on the server. Each client
server had a single drive on which we installed a fresh copy of Windows Server 2003 R2 Enterprise Edition. We installed
the .NET 3.5 SP1 framework on each client, as the DS2 test executable requires at least .NET2.0. After the installation,
we created two folders on the server, one for each client instance, to store the DS2 executable. We followed this
process for each installation:
1. Install Microsoft Windows Server 2003 R2 Enterprise Edition with Service Pack 2 on the client.
2. Assign a computer name of Clientx for the database client, where x is the client number.
3. For the licensing mode, use the default setting of five concurrent connections.
4. Enter a password for the administrator logon.
5. Select Eastern Time Zone.
6. Use typical settings for the Network installation.
7. Type Workgroup for the workgroup.
8. Install Windows Updates, .NET 3.5 SP1 framework, and copy the DVD Store client executable into each of the
two folders.
Creating scripts on the database clients
To simplify testing, we created batch files named test.bat on all eight clients to start the DVD Store executable
with the correct parameters. We put the batch files on the clients: c:clientshare. The batch files in c:clientshare on four
of the clients contained the text below. The batch files on the other four clients contained the same text, but the driver
pointed to the different database with –database_name=ds2-1.
c:clientshareds2sqlserverdriver.exe --target=192.168.2.120 --ramp_rate=10 --
run_time=30 --n_threads=16 --db_size=6GB --think_time=0 --database_name=ds2 --

Setting up DVD Store version 2.1
Data generation overview
We generated the data using the Install.pl script included with DVD Store version 2.1, providing the parameters
for our 6GB database size and the database platform on which we ran - Microsoft SQL Server. We ran the Install.pl script
on a utility system running Linux. The Install.pl script also generated the database schema.
After processing the data generation, we transferred the data files and schema creation files to a Windows-
based system running SQL Server 2008 R2 SP1. We built the 6GB database in SQL Server 2008 R2 SP1, and then
performed a full backup, storing the backup file on the C: drive for quick access. We used that backup file to restore on
the server between test runs.
The only modification we made to the schema creation scripts were the specified file sizes for our database. We
deliberately set the file sizes higher than necessary to ensure that no file-growth activity would affect the outputs of the
test. Besides this file size modification, the database schema was created and loaded according to the DVD Store
documentation. Specifically, we followed the steps below:
1. We generated the data and created the database and file structure using database creation scripts in the DS2
download. We made size modifications specific to our 6GB database and the appropriate changes to drive
letters.
2. We transferred the files from our Linux data generation system to a Windows system running SQL Server.
3. We created database tables, stored procedures, and objects using the provided DVD Store scripts.
4. We set the database recovery model to bulk-logged to prevent excess logging.
5. We loaded the data we generated into the database. For data loading, we used the import wizard in SQL Server
Management Studio. Where necessary, we retained options from the original scripts, such as Enable Identity
Insert.
6. We created indices, full-text catalogs, primary keys, and foreign keys using the database-creation scripts.
7. We updated statistics on each table according to database-creation scripts, which sample 18 percent of the
table data.
8. On the SQL Server instance, we created a ds2user SQL Server login using the following Transact SQL (TSQL)
script:
USE [master]
GO
CREATE LOGIN [ds2user] WITH PASSWORD=N’’,
DEFAULT_DATABASE=[master],
DEFAULT_LANGUAGE=[us_english],
CHECK_EXPIRATION=OFF,
CHECK_POLICY=OFF
GO
9. We set the database recovery model back to full.
10. We created the necessary full text index using SQL Server Management Studio.
11. We created a database user and mapped this user to the SQL Server login.
12. We then performed a full backup of the database. This backup allowed us to restore the databases to a pristine
state relatively quickly between tests.
Figure 9 shows our initial file size modifications.

Editing the workload script – ds2xdriver.cs module
A new feature of DVD Store version 2.1 is the ability to target multiple targets from one source client. We used
this functionality. In order to record the orders per minute output from each specific database target, we modified the
ds2xdriver to output this information to log files on each client system. To do this, we used the StreamWriter method to
create a new text file on the client system, and the WriteLine and Flush methods to write the relevant outputs to the
files during the tests. We also added the capabilities to target differently named databases.
After making these changes, we recompiled the ds2xdriver.cs and ds2sqlserverfns.cs module in Windows by
following the instructions in the DVD Store documentation. Because the DS2 instructions were for compiling from the
command line, we used the following steps on a system with Visual Studio installed:
1. Open a command prompt.
2. Use the cd command to change to the directory containing our sources.
3. Execute the following command:
csc /out:ds2sqlserverdriver.exe ds2xdriver.cs ds2sqlserverfns.cs
/d:USE_WIN32_TIMER /d:GEN_PERF_CTRS
Setting up disk drives for the database
We installed two Pliant LB 150S SSD drives in both servers for the database and log files. We configured the
drives as two individual disks and named them volume1 (E:) and volume2 (F:). We put the database and logs on different
volumes. For example, the database 1 files were on volume1 and the log files were on volume2. We reversed this for the
next database, so database 2 files were on volume2 and the log files were on volume1. We repeated these steps for the
remaining database instances. This setup ensured equal disk activity on both RAID volumes.

APPENDIX D – JAVA WORKLOAD
SPECjbb2005 configuration
We used SPECjbb2005 version 1.07, dated March 15, 2006. We followed SPEC’s run rules. (For more information
about SPECjbb2005 and its run rules, see http://www.spec.org/jbb2005/docs/RunRules.html.) We installed SPECjbb2005
by copying the contents of the SPECjbb2005 CD to the directory C:SPECjbb2005v1.07 on the server’s hard disk.
SPECjbb2005 requires a Java Virtual Machine on the system under test. We used Java HotSpot 64-bit Server VM
(build 20.6-b01 for this testing and left the default installation settings.
For an official SPECjbb2005 run, as per the run rules, the end user should edit the SPECjbb_config.props file in
the root SPECjbb2005 directory to include disclosure information about the server and our license information. We did
not do this step, as our goal was to create a server load and not produce actual SPECjbb2005 results. We modified the
SPECjbb.props file to change the number of JVM instances to two. This change allows a server to run two JVM instances
during testing.
We created a batch file, which we placed in the root SPECjbb2005 directory, to issue the Java run command to
launch the benchmark. During testing, we used the command prompt window within Microsoft Windows Server 2008
R2 Enterprise Edition to run this batch file. The contents of this file are shown below.

APPENDIX E – MEASURING POWER
Measuring workload power
To record each server’s power consumption during the workload test, we used an Extech Instruments®
(www.extech.com) 380803 Power Analyzer/Datalogger. We connected the power cord from the server under test to the
Power Analyzer’s output load power outlet. We then plugged the power cord from the Power Analyzer’s input voltage
connection into a 120-volt power outlet.
We used the Power Analyzer’s Data Acquisition Software (version 2.11) to capture all recordings. We installed
the software on a separate Intel processor-based PC, which we connected to the Power Analyzer via an RS-232 cable.
We captured power consumption at one-second intervals.
To gauge the power usage with no OS activity, we recorded the power usage for 2 minutes while each server
was running the operating system but no applications running.
We then recorded the power usage (in watts) for each server during the testing at one-second intervals. To
compute the average power usage, we averaged the power usage during the time the server was producing its peak
performance results. We call this time the power measurement interval.
Measuring response time power
To record the power limit response time, we used a Yokogawa® WT210 with WTViewer 8.11 software. We
connected a power strip to the Yokogawa WT210 and recorded the Dell PowerEdge R720 server using a 120-volt supply
voltage. We connected the WT210 to a desktop via an RS-232 cable. We set the recording time intervals to 100ms inside
WTViewer. Note: WTViewer records data at a minimum interval of 200ms due to the RS-232 interface.
