This document summarizes tests run on an IBM System x3850 X5 server connected to IBM System Storage DS3400 storage controllers to evaluate how additional memory capacity on the server can benefit SQL Server data warehouse workloads. Six queries were run against a 300GB SQL Server database with 64GB, 128GB, 256GB, and 512GB of server memory. The results showed only minor improvements from 64GB to 128GB, but significant response time reductions of over 50% for most queries when increasing memory to 256GB or 512GB. Additional memory above 128GB provided substantial performance benefits for these data warehouse workloads.

Many growing businesses employ a combination of HDDs and SSDs in their datacenters to provide storage for users. Software-defined storage additions, such as Windows Storage Spaces, can help improve workload performance by using tiering and caching technologies with enabling hardware. When combined with this software, the new Intel processor-powered Dell PowerEdge R730xd can provide storage support for the increasing workload performance of your business. We found that the PowerEdge R730xd provided support for 16.5 times more file server IOPS, and up to 94.7 lower latency, than the PowerEdge R720xd. If your business needs storage and performance to support its growth, consider the new Dell PowerEdge R730xd.
Performance of persistent apps on Container-Native Storage for Red Hat OpenSh...Principled Technologies
The document summarizes benchmark testing of Container-Native Storage (CNS) on Red Hat OpenShift Container Platform using two different storage media: solid-state drives (SSDs) and hard disk drives (HDDs). It tested CNS under IO-intensive and CPU-intensive workloads. For the IO-intensive workload, the SSD configuration significantly outperformed the HDD configuration, achieving over 5 times the maximum performance. However, for the CPU-intensive workload, the two configurations achieved similar maximum performance levels, with SSDs having less than a 5% improvement. The testing demonstrated that CNS can provide scalable storage and that storage performance depends on understanding how it matches the workload characteristics.

Taylor Swift's song "Shake It Off" is about ignoring criticism and haters. The lyrics describe how people say negative things, but the singer keeps "cruising" with music in her mind, shaking off the haters and heartbreakers. She dances alone and makes up her own moves, shaking off what people don't see or know. The players and haters are going to play and hate, but the singer is just going to shake it off and keep dancing to this "sick beat."
1. A 65-year-old male developed petechial rash and bleeding gums about 1 week after starting atorvastatin 10mg daily for dyslipidemia. His platelet count dropped to 1500/cumm.
2. Atorvastatin was discontinued and the patient was treated with steroids. His platelet counts improved gradually and returned to normal after 10 days of stopping atorvastatin.
3. Other potential causes of thrombocytopenia were ruled out. The temporal relationship between starting atorvastatin and developing thrombocytopenia suggests atorvastatin likely caused the patient's drug-induced thrombocytopenia.

Scaling Oracle 12c database performance with EMC XtremIO storage in a Databas...Principled Technologies
Oracle single instance database VMs need plenty of storage capacity and performance to handle increased workload demands placed on them by users. Whether your organization uses DBaaS or traditional Oracle 12c instances, consider the reliable performance and scaling flexibility that the EMC XtremIO storage array can offer. We found IOPS levels stayed consistent as we scaled up to eight Oracle single instance VMs and scaled by an average of 14,700 IOPS for each VM (totaling 118,067). In addition, we found that the inline deduplication, compression, and thin provisioning capabilities on the XtremIO array resulted in an overall efficiency ratio of 51 to 1 and a data reduction ratio of 14.6 to 1. With this level of consistent performance, users can expect great performance to meet high demand for IOPS in a DBaaS environment.

Upgrading the hardware running your SQL Server to a space-efficient modular Dell EMC modern environment can help your company achieve a great deal of database work in a small amount of space. With the Dell Express Flash technology, adding a caching solution such as Samsung AutoCache can make the environment even more efficient.
In the PT labs, we ran a mixed database workload on six Dell EMC PowerEdge FC630 servers, powered by Intel Xeon E5-2667 processors, in three PowerEdge FX2 enclosures. The solution included the QLogic QLE2692 16Gb FC adapter with StorFusion Technology, Dell EMC Storage SC9000 all-flash storage, and Dell EMC PowerEdge Express Flash NVMe Performance PCIe SSDs.
With no caching solution, the 36 SQL Server 2016 VMs on the six servers achieved a total of 431,839 orders per minute while an Oracle workload ran on 12 VMs. When we added a caching solution to accelerate the SQL database volumes, the performance across the 36 SQL Server 2016 VMs doubled to 871,580. These numbers show the power of server-side caching to alleviate pressure on the storage array allowing you to get even more out of the Dell EMC modern environment.

Executive Overview
A Data Warehouse (DW) is a type of database designed to archive data for the purposes of
reporting and analysis. Data Warehouses are typically used as the back-end data storage for
Decision Support Systems (DSS). A DW environment is different from an OLTP (online
transaction processing) database in that it is often subjected to ad hoc queries rather than the
predefined queries typical of the OLTP database. Queries run against DW databases often scan
millions of rows, whereas typical OLTP queries generally scan a handful of records. The DSS I/O
pattern is mostly large sequential reads, compared to small random reads with an OLTP
workload.
This technical report documents a series of tests that demonstrate the benefits of using large
amounts of server memory for a large-scale Decision Support System workload.
® ®
For this series of tests, a Microsoft SQL Server 2008 300GB data warehouse was used running
on an IBM® System x3850 X5 32-core server connected via Fibre Channel to an IBM System
Storage™ DS3400 storage controller.
IBM System x3850 X5
The x3850 X5 is built on eX5, the fifth generation of IBM X-Architecture® chipset technology. This
new system incorporates the latest in hardware acceleration and scalability providing resource
configurations that push the boundaries of x86/x64-based systems while providing industry-
leading flexibility. With the release of new multi-core processors from Intel®, the 4-socket IBM
System x3850 X5 now offers up to 32 cores or 64 logical processors with Hyper-Threading
Technology and up to 1TB of memory per chassis. The memory is highly available, incorporating
such IBM OnForever™ features as Memory ProteXion™, Chipkill™ error correction, memory rank
sparing, memory scrubbing, and memory mirroring. Other high-availability features, such as hot-
swap redundant fans and power supplies (with 220V AC input), and hot-swap HDDs and solid-
state drives (SSDs) deliver high levels of reliability and availability to maximize up-time. These
kinds of features provide the reliability and high availability needed for the most demanding
virtualization requirements.
Compared to the previous-generation server, the x3850 X5 doubles the memory capacity to 64
DIMM slots/1TB of PC3-10600 double data rate 3 (DDR3) memory. (Using the optional 1U
MAX5 memory expansion unit, the x3850 X5 has access to an additional 32 DIMM slots, for a
total of 1.5TB of memory in only 5U.) This paper will demonstrate how leveraging the memory
capabilities of the x3850 X5 can take the performance, efficiency and reliability of your Data
Warehouse environment to the next level.
http://ibm.com/systems/x/hardware/enterprise/x3850x5/index.html
IBM System Storage DS3400
DSS workloads require large bulk reads, so it’s important to maximize throughput and minimize,
or eliminate, potential bottlenecks that can occur in the storage system or the storage
interconnects. The DS3400 was chosen as the appropriate storage platform because it met the
requirements for large capacity, high throughput, and the capability to sustain a high IOPS (I/O
operations per second) rate. The DS3400 features a 4Gbps Fibre Channel (FC) interface for
either direct-attach storage (DAS) or SAN-ready solutions.
The combination of 12 SAS or SATA 3.5" drives per enclosure provides the option to scale to
5.4TB of storage capacity with 450GB hot-swappable SAS disks or 12.0TB with 1.0TB hot-
swappable SATA disks in the first enclosure. The DS3400 is expandable by attaching up to three
additional EXP3000 storage enclosures for a total of 21.6TB of storage capacity with 450GB SAS
or up to 48.0TB with 1.0TB SATA.

Microsoft SQL Server 2008
SQL Server 2008 running on Microsoft Windows® Server 2008 enables organizations to build
comprehensive, enterprise-scale analytic solutions that deliver intelligence where customers want
it.
SQL Server 2008 makes a major advance in Data Warehouse scalability. The database engine
contains numerous enhancements designed to improve both absolute performance and multi-
processor scaling on decision support workloads.
Test Environment
Decision support workloads are frequently very I/O intensive. The high I/O requirements of these
tests were met using DS3400 storage systems connected to the IBM x3850 X5 server using
multiple Fibre Channel inter-connects.
Figure 1 illustrates the topology of the Data Warehouse workload test environment. The x3850 X5
server was connected to seven DS3400 storage controllers using fourteen 8Gbps Fibre Channel
interconnects (two FC links per controller).
Note: Although the host bus adapters (HBAs) are designed to operate at 8Gbps, they auto-
negotiate to 4Gbps due to the 4Gbps FC interface of the DS3400 storage controllers.
Figure 1. Test Configuration
Server Configuration
The x3850 X5 incorporated four Intel Xeon® X7560 8-core processors (32 cores). All seven PCIe
slots were populated with Emulex LPE 12002-M8 8Gb HBAs. The tests were performed with
64GB, 128GB, 256GB, and 512GB of memory.

Storage Configuration
Figure 2 illustrates the storage configuration. Four RAID-1 arrays were created on each storage
controller. Two logical drives were created on each of the RAID-1 arrays. The 300GB test
database as well as SQL Server’s TempDB were spread across the 56 logical drives. The SQL
log file was on a separate array.
Figure 2. Storage Configuration showing 28 RAID-1 arrays, each with two logical drives
Analysis
Looking at Graph 3, there is only a slight reduction in query response times for most queries
when moving from 64GB to 128GB of server memory. Only queries 3 and 6 show a fair amount of
improvement. However, when moving from 128GB of memory to 256GB or 512GB, we start
seeing the benefits of the additional memory in terms of much reduced response time on all the
queries.
Queries Used
The following queries were executed against the 300GB database:
Query 1 (Q1) - Shipping Priority Query
This query retrieves the shipping priority and potential revenue of the top 10 orders having the
largest revenue among those that had not been shipped as of a given date.
Query 2 (Q2) - Local Supplier Volume Query
This query lists the revenue volume that resulted from line-item transactions in which the
customer ordering parts and the supplier filling them were both within that nation for a particular
year.
5. eX5 Memory Advantage: How Add’l Capacity Can Benefit SQL Server DW Workloads
Page 5
Query 3 (Q3) - National Market Share Query
This query determines how the market share of a given nation within a given region has changed
over two years for a given part type.
Query 4 (Q4) - Returned Item Reporting Query
This query identifies the top 20 customers who might be having problems with the parts that are
shipped to them for a given quarter.
Query 5 (Q5) - Small-Quantity-Order Revenue Query
This query determines how much average yearly revenue would be lost if orders were no longer
filled for small quantities of certain parts. This may reduce overhead expenses by concentrating
sales on larger shipments.
Query 6 (Q6) - Discounted Revenue Query
This query reports the gross discounted revenue attributed to the sale of selected parts that were
shipped by air or delivered in person.
Test Results
The following graph shows the comparison of query response times for each of the six queries
with 64GB, 128GB, 256GB, and 512GB of server memory.
Figure 3. Test results
Note: The following results use 64GB as the baseline performance.
6. eX5 Memory Advantage: How Add’l Capacity Can Benefit SQL Server DW Workloads
Page 6
Query 1 Results
When doubling the memory from 64GB to 128GB we see a slight improvement in query response
time. However, when executing the query with 256GB or 512GB, we get a 57% reduction in query
response time for both runs.
It appears that the dataset for this query was greater than 128GB and less than 256GB, which is
why we see similar performance for the 64GB and 128GB runs and then again for the 256GB and
512GB runs. When executing the query with 256GB and 512GB, the entire dataset could fit into
memory. In this case, no further reduction in query response time can be realized by increasing
memory from 256GB to 512GB.
Query 2 Results
As in query 1, we see a slight improvement in query response time when doubling memory from
64GB to 128GB, which tells us the dataset was too large to fit into memory. When executing the
query with 256GB, we get a 38% reduction in query response time. It appears much of the
dataset was able to fit into memory when executing with 256GB. However, not everything fit into
memory, because when executing with 512GB, we see a 71% reduction in query response time.
Query 3 Results
In query 3, we see a 26% reduction in query response time when moving from 64GB to 128GB.
When we execute the query with 256GB and 512GB, we get 52% and 59% reductions,
respectively.
Query 4 Results
Query 4 is almost identical to query 1. Query response time remains the same when executing
with both 64GB and 128GB, and then drops 65% when memory is increased from 128GB to
256GB (no change with 512GB).
Query 5 Results
Query 5 displays very linear improvement when more memory is added. When executing the
query with 128GB of memory, we see a 19% reduction in query response time. The 256GB run
reduces the query response time by 56%. Finally when executed with 512GB of server memory,
we see a 93% reduction in query response time.
It appears that the dataset was larger than 256GB but smaller than 512GB. The query was able
to execute very quickly on the 512GB test run because the entire dataset resided in memory.
Query 6 Results
Query 6 tells a similar story to query 3. We see a 39% reduction in query response time when
executing with 128GB of memory. When the query is executed with 256GB and 512GB, we see a
92% and a 95% reduction, respectively.
Conclusion
I/O is the slowest component in a Data Warehouse configuration. When you run a query against
a database, the server needs to process data. Data is stored on the storage, and reads are
issued to gather the dataset. On a system with a small amount of memory, current data in
memory needs to be evicted to make room for the dataset. If the evicted data is needed later, it
must be retrieved again and again.
7. eX5 Memory Advantage: How Add’l Capacity Can Benefit SQL Server DW Workloads
Page 7
On a system with a large amount of memory, more of the dataset can remain in memory, and
future references to the dataset will be satisfied at very low latencies, reducing the query
response times significantly. If achieving faster query response times is your goal, then one way
to achieve that goal is to use enough memory to keep most or all of the dataset in memory. This
will let you reduce the amount of storage needed for the same I/O bandwidth, which can offset
the cost of adding memory. IBM offers multiple effective solutions with the 4-to-8-socket x3850
X5 that supports up to 1TB of memory natively, up to 1.5TB, using an x3850 X5 and a 1U MAX5
memory expansion unit, and up to 2TB using two x3950 X5 chassis; or the 2-socket x3690 X5
server, which supports up to 512GB natively or up to 1TB using a server and MAX5 unit; or the 2-
to-4-socket HX5 blade server, which supports up to 128GB natively, up to 256GB using two HX5
servers; or up to 320GB using one HX5 and one MAX5.
The results presented in this paper demonstrate the benefits of running your workload in these
large memory configurations.
