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.

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.

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.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Harnessing the Power of NLP and Knowledge Graphs for Opioid Research
Workstation heat, sound, and power usage: Lenovo ThinkStation S30 and the Dell Precision T3600 workstation
1. WORKSTATION HEAT, SOUND, AND POWER USAGE:
LENOVO THINKSTATION S30 VS. DELL PRECISION T3600
When selecting a workstation, it’s important to consider how it will
contribute to a reliable and comfortable work environment for the user and
how much electricity it will require. Workstations vary considerably in the
amount of heat and noise they generate and in the amount of power they
consume. A system with a cooler operating temperature helps you two ways: by
being less likely to fail and by requiring less air conditioning to keep the office at
a comfortable temperature. A quieter system provides a more pleasant user
experience and a more power-efficient system lowers your electric bill by using
less electricity and running cooler which reduces the amount of cooling
required.
In our labs, Principled Technologies (PT) tested the Lenovo ThinkStation
S30 and the Dell Precision T3600 workstation. We found that the Lenovo
workstation was quieter and less power-hungry than the Dell workstation, and
had lower surface temperatures while idle and while under load. These findings
show that the Lenovo ThinkStation S30 could contribute to a reliable user
experience and a comfortable office environment and save on electricity costs.

2. WHICH WORKSTATION MAKES FOR A RELIABLE, PLEASANT,
AND POWER-EFFICIENT WORK ENVIRONMENT?
A workstation that generates more heat and noise and uses more
power than necessary can be more prone to system failure, can be distracting
and uncomfortable for workers, and can boost electricity bills—both because of
the power the system itself draws and the power that additional air
conditioning uses. To determine how two workstations compared on these
fronts, we measured the heat, noise, and power consumption of the Lenovo
ThinkStation S30 and the Dell Precision T3600 workstation.
We performed the tests while the two systems were idle and again
while they were running a heavy workload that consisted of two benchmarks
stressing each system’s hard disk, processor, and memory.
Figure 1 presents highlights of our test results.

COOL UNDER PRESSURE
The operating temperatures of computers vary considerably. While one
advantage of a cooler workstation is obvious—no one wants a hot office—
workstations running at cooler temperatures also bring other benefits.
It is well known within the IT industry that operating temperatures
degrade hardware reliability. Excess heat can cause hard drives, CPUs, memory,
and other components to fail. For example, overheating can expand hard drive
platters, causing hard drive failure. At the very least, excess heat can reduce the
Workstation heat, sound, and power usage: Lenovo A Principled Technologies report 2

3. drive’s effective operating life. According to a recent Fujitsu white paper, hard
disk manufacturers now suggest cooler operating temperatures for drive
enclosures.1 Because many users fail to back up their data on a regular basis,
adequate ventilation and cooling in a workstation goes a long way to avoiding
problems such as catastrophic data loss due to hard drive failure.
Many workers are not fortunate enough to have control over the
climate in their offices. Not only do workstations with higher operating
temperatures place extra wear on hardware, but they can make an already
warm office even more uncomfortable.
With system reliability and user comfort in mind, we measured the
temperature of several key internal and external spots on the two workstations
while they were idle and while they were running a heavy workload. However,
given that most workstations run 24 hours a day, we believe the most
appropriate measure of thermal performance is the temperature of the air
exiting the rear exhaust when the workstation is idle.
For each of the locations, we measured the temperature three times
and noted the number of degrees Celsius each measurement deviated from the
ambient room temperature. Because the ambient temperature varied
throughout our testing, the temperature difference between the ambient
temperature and the surface temperature we recorded for each system makes
the fairest comparison.
QUIETER IS BETTER
Any user, given a choice, would prefer a quiet system to a noisy one. As
Figure 2 shows, the Lenovo ThinkStation S30 was considerably quieter than the
Dell Precision T3600 under both load conditions.
We calculated the difference in perceived volume with the two
workstations using the following formula2 for sound level change:
The change in sound level (L) is related to the ratio for loudness (or
volume) by using the calculated L as follows:
For example, if the level change (L) is 1.9dB, the ratio for loudness is
1.141x, or 14.1 percent louder.

14.1 percent louder than the Lenovo ThinkStation S30 when the systems were
idle and 15.7 percent louder when they were under load.

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.
We then recorded the power usage (in watts) for each system during the testing at 1-second
intervals. To compute the average power usage, we averaged the power usage during the time the
system was producing its peak performance results.
