Migrating server workloads to Red Hat Enterprise Virtualization on Intel Xeon...Principled Technologies
Consolidating to a virtualized environment that supports VMs running the original operating systems can help you save on data center costs and eliminate retuning and testing costs that can be necessary when porting applications. You can reinstall the operating systems, such as Red Hat Enterprise Linux 5.8, on VMs and copy the application software and configuration to them. Selecting a virtual environment that optimizes performance and improves price/performance can lead to significant savings in the data center. You can get better performance and greater efficiency by replacing several older servers with newer ones powered by Intel® Xeon® processors running Red Hat Enterprise Virtualization, reducing the number of servers you need to run and maintain.
In our tests, we easily and successfully migrated a middleware application running on Red Hat Enterprise Linux on a two- to three-year-old bare-metal server to virtual machines on Red Hat Enterprise Virtualization 3 Hypervisor using Intel® Xeon® processors E5-2690.
Not only was there minimal disruption of the workload, but performance increased dramatically—by 90.3 percent when we ran one VM and by 143.8 percent when we ran two VMs.
These findings demonstrate that moving older servers to Red Hat Enterprise Virtualization VMs with newer Intel® Xeon® processors can provide all of the benefits of virtualization while significantly improving application performance.

Investing in GenAI: Cost‑benefit analysis of Dell on‑premises deployments vs....Principled Technologies
Conclusion
Diving into the world of GenAI has the potential to yield a great many benefits for your organization, but it first requires consideration for how best to implement those GenAI workloads. Whether your AI goals are to create a chatbot for online visitors, generate marketing materials, aid troubleshooting, or something else, implementing an AI solution requires careful planning and decision-making. A major decision is whether to host GenAI in the cloud or keep your data on premises. Traditional on-premises solutions can provide superior security and control, a substantial concern when dealing with large amounts of potentially sensitive data. But will supporting a GenAI solution on site be a drain on an organization’s IT budget?
In our research, we found that the value proposition is just the opposite: Hosting GenAI workloads on premises, either in a traditional Dell solution or using a managed Dell APEX pay-per-use solution, could significantly lower your GenAI costs over 3 years compared to hosting these workloads in the cloud. In fact, we found that a comparable AWS SageMaker solution would cost up to 3.8 times as much and an Azure ML solution would cost up to 3.6 times as much as GenAI on a Dell APEX pay-per-use solution. These results show that organizations looking to implement GenAI and reap the business benefits to come can find many advantages in an on-premises Dell solution, whether they opt to purchase and manage it themselves or choose a subscription-based Dell APEX pay-per-use solution. Choosing an on-premises Dell solution could save your organization significantly over hosting GenAI in the cloud, while giving you control over the security and privacy of your data as well as any updates and changes to the environment, and while ensuring your environment is managed consistently.

Workstations powered by Intel can play a vital role in CPU-intensive AI devel...Principled Technologies
In three AI development workflows, Intel processor-powered workstations delivered strong performance, without using their GPUs, making them a good choice for this part of the AI process
Conclusion
We executed three AI development workflows on tower workstations and mobile workstations from three vendors, with each workflow utilizing only the Intel CPU cores, and found that these platforms were suitable for carrying out various AI tasks. For two of the workflows, we learned that completing the tasks on the tower workstations took roughly half as much time as on the mobile workstations. This supports the idea that the tower workstations would be appropriate for a development environment for more complex models with a greater volume of data and that the mobile workstations would be well-suited for data scientists fine-tuning simpler models. In the third workflow, we explored tower workstation performance with different precision levels and learned that using 16-bit floating point precision allowed the workstations to execute the workflow in less time and also reduced memory usage dramatically. For all three AI workflows we executed, we consider the time the workstations needed to complete the tasks to be acceptable, and believe that these workstations can be appropriate, cost-effective choices for these kinds of activities.

Get comparable online transaction processing (OLTP) performance with or without enabling AMD Secure Memory Encryption and AMD Secure Encrypted Virtualization - Encrypted State
Conclusion
You’ve likely already implemented many security measures for your servers, which may include physical security for the data center, hardware-level security, and software-level security. With the cost of data breaches high and still growing, however, wise IT teams will consider what additional security measures they may be able to implement.
AMD SME and SEV-ES are technologies that are already available within your AMD processor-powered 16th Generation Dell PowerEdge servers—and in our testing, we saw that they can offer extra layers of security without affecting performance. We compared the online transaction processing performance of a Dell PowerEdge R7625 server, powered by AMD EPYC 9274F processors, with and without these two security features enabled. We found that enabling AMD Secure Memory Encryption and Secure Encrypted Virtualization-Encrypted State did not impact performance at all.
If your team is assessing areas where you might be able to enhance security—without paying a large performance cost—consider enabling AME SME and AMD SEV-ES in your Dell PowerEdge servers.

In three AI development workflows, Intel processor-powered workstations delivered strong performance, without using their GPUs, making them a good choice for this part of the AI process
Conclusion
We executed three AI development workflows on tower workstations and mobile workstations from three vendors, with each workflow utilizing only the Intel CPU cores, and found that these platforms were suitable for carrying out various AI tasks. For two of the workflows, we learned that completing the tasks on the tower workstations took roughly half as much time as on the mobile workstations. This supports the idea that the tower workstations would be appropriate for a development environment for more complex models with a greater volume of data and that the mobile workstations would be well-suited for data scientists fine-tuning simpler models. In the third workflow, we explored tower workstation performance with different precision levels and learned that using 16-bit floating point precision allowed the workstations to execute the workflow in less time and also reduced memory usage dramatically. For all three AI workflows we executed, we consider the time the workstations needed to complete the tasks to be acceptable, and believe that these workstations can be appropriate, cost-effective choices for these kinds of activities.
Enable security features with no impact to OLTP performance with Dell PowerEd...Principled Technologies
Get comparable online transaction processing (OLTP) performance with or without enabling AMD Secure Memory Encryption and AMD Secure Encrypted Virtualization - Encrypted State
Conclusion
You’ve likely already implemented many security measures for your servers, which may include physical security for the data center, hardware-level security, and software-level security. With the cost of data breaches high and still growing, however, wise IT teams will consider what additional security measures they may be able to implement.
AMD SME and SEV-ES are technologies that are already available within your AMD processor-powered 16th Generation Dell PowerEdge servers—and in our testing, we saw that they can offer extra layers of security without affecting performance. We compared the online transaction processing performance of a Dell PowerEdge R7625 server, powered by AMD EPYC 9274F processors, with and without these two security features enabled. We found that enabling AMD Secure Memory Encryption and Secure Encrypted Virtualization-Encrypted State did not impact performance at all.
If your team is assessing areas where you might be able to enhance security—without paying a large performance cost—consider enabling AME SME and AMD SEV-ES in your Dell PowerEdge servers.

In high-temperature test scenarios, a Dell PowerEdge HS5620 server continued running an intensive workload without component warnings or failures, while a Supermicro SYS‑621C-TN12R server failed
Conclusion: Remain resilient in high temperatures with the Dell PowerEdge HS5620 to help increase efficiency
Increasing your data center’s temperature can help your organization make strides in energy efficiency and cooling cost savings. With servers that can hold up to these higher everyday temperatures—as well as high temperatures due to unforeseen circumstances—your business can continue to deliver the performance your apps and clients require.
When we ran an intensive floating-point workload on a Dell PowerEdge HS5620 and a Supermicro SYS-621CTN12R in three scenario types simulating typical operations at 25°C, a fan failure, and an HVAC malfunction, the Dell server experienced no component warnings or failures. In contrast, the Supermicro server experienced warnings in all three scenario types and experienced component failures in the latter two tests, rendering the system unusable. When we inspected and analyzed each system, we found that the Dell PowerEdge HS5620 server’s motherboard layout, fans, and chassis offered cooling design advantages.
For businesses aiming to meet sustainability goals by running hotter data centers, as well as those concerned with server cooling design, the Dell PowerEdge HS5620 is a strong contender to take on higher temperatures during day-to-day operations and unexpected malfunctions.

Three AMD EPYC processor-based two-processor solutions outshined comparable Intel Xeon Scalable processor-based solutions by handling more Redis workload transactions and requests while consuming less power
Conclusion
Performance and energy efficiency are significant factors in processor selection for servers running data-intensive workloads, such as Redis. We compared the Redis performance and energy consumption of a server cluster in three AMD EPYC two-processor configurations against that of a server cluster in two Intel Xeon Scalable two-processor configurations. In each of our three test scenarios, the server cluster backed by AMD EPYC processors outperformed the server cluster backed by Intel Xeon Scalable processors. In addition, one of the AMD EPYC processor-based clusters consumed 20 percent less power than its Intel Xeon Scalable processor-based counterpart. Combining these measurements gave us power efficiency metrics that demonstrate how valuable AMD EPYC processor-based servers could be—you could see better performance per watt with these AMD EPYC processor-based server clusters and potentially get more from your Redis or other data intensive applications and workloads while reducing data center power costs.

We deployed this modern environment, then migrated database VMs from legacy servers and saw performance improvements that support consolidation
Conclusion
If your organization’s transactional databases are running on gear that is several years old, you have much to gain by upgrading to modern servers with new processors and networking components and an OpenShift environment. In our testing, a modern OpenShift environment with a cluster of three Dell PowerEdge R7615 servers with 4th Generation AMD EPYC processors and high-speed 100Gb Broadcom NICs outperformed a legacy environment with MySQL VMs running on a cluster of three Dell PowerEdge R7515 servers with 3rd Generation AMD EPYC processors and 25Gb Broadcom NICs. We also easily migrated a VM from the legacy environment to the modern environment, with only a few steps required to set up and less than ten minutes of hands-on time. The performance advantage of the modern servers would allow a company to reduce the number of servers necessary to perform a given amount of database work, thus lowering operational expenditures such as power and cooling and IT staff time for maintenance. The high-speed 100Gb Broadcom NICs in this solution also give companies better network performance and networking capacity to grow as they embrace emerging technologies such as AI that put great demands on networks.

Upgrade your cloud infrastructure with Dell PowerEdge R760 servers and VMware...Principled Technologies
Compared to a cluster of PowerEdge R750 servers running VMware Cloud Foundation 4.5
Conclusion
If your company is struggling with underperforming infrastructure, upgrading to 16th Generation Dell PowerEdge servers running VCF 5.1 could be just what you need to handle more database throughput and reduce vSAN latencies. We found that a Dell PowerEdge R760 server cluster running VCF 5.1 processed over 78 percent more TPM and 79 percent more NOPM than a Dell PowerEdge R750 server cluster running VCF 4.5. It’s also worth noting that the PowerEdge R750 cluster bottlenecked on vSAN storage, with max write latency at 8.9ms. For reference, the PowerEdge R760 cluster clocked in at 3.8ms max write latency. This higher latency is due in part to the single disk group per host on the moderately configured PowerEdge R750 cluster, while the better-configured PowerEdge R760 cluster supported four disk groups per host. As an additional benefit to IT admins, we also found that the embedded VMware Aria Operation adapter provided useful infrastructure insights.
Based on our research using publicly available materials, it appears that Dell supports nine of the ten PC security features we investigated, HP supports six of them, and Lenovo supports three features.

3. EXECUTIVE SUMMARY
With the dominance of cloud computing in today’s marketplace, companies
require a reliable and powerful platform on which to deliver their cloud and application
services. The massive data centers designed to provide cloud computing services require
a large number of servers that are efficient, powerful, flexible, and easy to maintain.
Software must be low cost, feature laden, and easy to integrate. Using a low-cost
operating system paired with the Dell PowerEdge C series servers can allow service
providers and other companies to deliver high-quality and efficient applications to their
customers.
Dell designed the Dell PowerEdge C series, which includes the Dell PowerEdge
C6220, specifically to meet the needs of these organizations that need to deploy large-
scale environments. In this reference architecture, we look at some of the many
benefits that the Dell PowerEdge C6220 server can bring to large deployments and
describe in detail the setup of a common configuration: FreeBSD running on the Dell
PowerEdge C6220.
Organizations often use open-source operating systems, such as FreeBSD, in
these hyper-scale environments due to their price point, flexibility, ease of
management, and performance capabilities. These operating systems offer many built-
in application stacks, hypervisors, and other features that allow organizations to offer
their customers a comprehensive set of services. In this document, we walk you through
the task of deploying one such operating system, FreeBSD, and the Apache/MySQL/PHP
(AMP) application stack on one node of the PowerEdge C6220, from start to finish.
The Dell PowerEdge C6220 server
The Dell PowerEdge C6220 server features up to four independent 1U hot-
swappable, two-socket server nodes that each harness the power of the Intel® Xeon®
processor E5-2600 series to maximize performance for hyper-scale environments.
Designed for flexibility, the multiple independent server nodes allow you to mix and
match workloads on different servers within the same chassis. If your requirements
demand it, configurations are available that feature just two independent 2U nodes,
with greater I/O capacity. The high performance levels it delivers, coupled with a simple,
modular, and easy-to-maintain design, make the Dell PowerEdge C6220 an optimal
choice for large software as a service (SaaS) and cloud deployments. Figure 1 presents a
1U server node of the Dell PowerEdge C6220.
The Dell PowerEdge C6220 is available with multiple storage controller options,
such as onboard storage with the Intel C600 chipset, the LSISAS2008 6Gb SAS mezzanine

used the LSISAS2008 6Gb SAS mezzanine card.
Figure 1: 1U server node of the Dell PowerEdge C6220 with the LSISAS2008 mezzanine
card.
The Dell PowerEdge C6220 can deliver many benefits to your large deployment,
and lets you:
• Make better use of expensive data center space by increasing the rack density with
four two-socket server nodes fitting into a standard 2U rack slot.
• Configure servers to better fit application and workload needs for increased
performance without reconfiguring your chassis and rack layout. You can easily use
1U nodes in a four-node configuration or 2U nodes in a two-node configuration.
Additionally, an optional expandable backplane allows for adjustable disk and
assignment and storage configurations.

6. INSTALLING FREEBSD ON THE DELL POWEREDGE
C6220
Prerequisites
BIOS requirements
When installing FreeBSD 9.0 STABLE, we used the default factory BIOS setting
for the server. Based on your workload requirements, BIOS settings may require
adjustment, but you should thoroughly test these changes prior to production
implementation.
Driver prerequisites
In our lab installation, we used a Dell PowerEdge C6220 with the LSISAS2008
mezzanine card. With this controller, FreeBSD (STABLE trunk) installs and runs without
extra hardware drivers or software modules on the Dell PowerEdge C6220, as of this
writing. If using the RELEASE trunk, you must install with a JBOD configuration.
Deployment options
We recognize in mass deployment situations there are various options for mass
OS deployment including Preboot eXecution Environment (PXE) or orchestration tools
such as Puppet. For this guide, however, we wish to prepare our “gold image” for
FreeBSD on a single Dell PowerEdge C6220 server node. To do this, we used its
embedded baseboard management controller (BMC) console and virtual installation
media.
Storage configuration
The Dell PowerEdge C6220 can use several storage controllers to guard against
disk failures. For this guide, we assume that we wish to change the disk configuration
from the factory installation. We created one RAID6 virtual disk using the LSISAS2008
RAID controller and the six 900GB internal hard drives assigned to the server.
As of early April 2012, the RELEASE version of FreeBSD 9.0 did not have the
necessary updated LSISAS2008 drivers. Therefore, it was necessary to use the STABLE
trunk of FreeBSD 9.0, which involved downloading the source code, recompiling, and
producing installable media. These driver updates should be in a future RELEASE
version, but until that time, you may find it necessary to use FreeBSD 9.0 STABLE to
avoid errors with the LSISAS2008 controller. We provide details of the STABLE source
download, recompile, and media creation in Appendix C.
We partitioned the virtual disk for both OS and application data. Detailed
instructions on how to configure the storage controller are in Appendix D.

Testing with a sample AMP application
To complete the AMP deployment, we created a sample AMP application
consisting of a test database with test data and a PHP script that creates a dynamic Web
page that prints the contents of a SQL query from the database. In this case, we
demonstrate using the well-known “Hello World” example.
Dell PowerEdge C6220 and FreeBSD 9.0: An AMP Reference Principled Technologies, Inc. 18
Architecture
19. 1. Log into the server as root.
2. Using the mysql client, create a test database, a test application user, and
set privileges:
mysql --user root –password=RootPassword
mysql> USE mysql;
mysql> CREATE DATABASE helloworlddb;
mysql> CREATE USER testappuser@localhost IDENTIFIED BY
'Password1';
mysql> GRANT ALL ON helloworlddb.* TO
testappuser@localhost;
mysql> FLUSH PRIVILEGES;
3. Exit the mysql client utility.
4. Using the mysql client, login as the test application user to the newly
created database and create a sample schema definition. In our case, this is
just one table with one column.
mysql --user testappuser --password=Password1
mysql> USE helloworlddb;
mysql> CREATE TABLE tbl_hello_world (testcol CHAR(100));
mysql> INSERT INTO tbl_hello_world (testcol) VALUES
("Hello World");
5. Exit the mysql client utility.
6. In the Apache Web data directory, located by default on FreeBSD at
/usr/local/www/apache22/data/, create a new file named helloworld.php
that will query the database and print the results. See Appendix E for this
sample PHP file contents.
7. From another machine, verify the page is operational by visiting
http://server_ip_address/helloworld.php
