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.

In our tests, Dell APEX Block Storage for AWS outperformed similarly configured solutions from Vendor A, achieving more IOPS, better throughput, and more consistent performance on both NVMe-supported configurations and configurations backed by Elastic Block Store (EBS) alone. Dell APEX Block Storage for AWS supports a full NVMe backed configuration, but Vendor A doesn’t—its solution uses EBS for storage capacity and NVMe as an extended read cache—which means APEX Block Storage for AWS can deliver faster storage performance.

We compared CPU performance and noise output of an HP Z2 G9 Tower Workstation in High Performance Mode to Dell Precision 3660 and 5860 tower workstations in optimized performance modes Conclusion HP Z2 G9 Tower Workstation users can change the BIOS settings to dial in the performance mode that best suits their needs: High Performance Mode, Performance Mode, or Quiet Mode. In good news for both creative and technical professionals, we found that an Intel Core i9-13900 processor-powered HP Z2 G9 Tower Workstation set to High Performance mode received higher CPU-based benchmark scores than both a similarly configured Dell Precision 3660 and a Dell Precision 5860 equipped with an Intel Xeon w5-2455x processor. Plus, the HP Z2 G9 Tower Workstation was quieter while running CPU-intensive Cinebench 2024 and SPECapc for Solidworks 2022 workloads than both Dell Precision tower workstations. This means HP Z2 G9 Tower Workstation users who prize performance over everything else can do so without sacrificing a quiet workspace.

In our PostgreSQL tests, R7i instances boosted performance over R6i instances with previous-gen processors If you use the open-source PostgreSQL database to run your critical business operations, you have many cloud options from which to choose. While many of these instances can do the job, some can deliver stronger performance, which can mean getting a greater return on your cloud investment. We conducted hands-on testing with the HammerDB TPROC-C benchmark to see how the PostgreSQL performance of Amazon EC2 R7i instances, enabled by 4th Gen Intel Xeon Scalable processors, stacked up to that of R6i instances with previous-generation processors. We learned that small, medium-sized, and large R7i instances with the newer processors delivered better OLTP performance, with improvements as high as 13.8 percent. By choosing the R7i instances, your organization has the potential to support more users, deliver a better experience to those users, and even lower your cloud operating expenditures by requiring fewer instances to get the job done.

How your organization can put artificial intelligence (AI) to work with Azure Cosmos DB Conclusion It’s clear that AI is bringing new opportunities to organizations across industries as they work to create more intelligent, AI-enabled applications. What is not always clear, though, is where and how to start with your own AI implementation on your own operational data. In this report, we’ve highlighted several possible use cases where Azure Cosmos DB, among other Azure services, may be able to help. To demonstrate how well some of these services work with Azure Cosmos DB, we found it straightforward to build a proof-of-concept intelligent chat application utilizing data we brought to the table. For your AI initiatives, consider exploring Azure Cosmos DB and the Azure ecosystem.

Utilizing Azure Cosmos DB for intelligent AI‑powered applications

Principled Technologies

We built an intelligent AI chat application using Microsoft Azure Cosmos DB for NoSQL and Azure AI Services Intelligent AI-powered applications drawing on your organizations’ own data have the potential to expand your capabilities and unlock myriad efficiencies. By storing your data in Azure Cosmos DB and starting with the Microsoft reference solution Vector Search & AI Assistant, like we did, you can start bringing value to your organization quickly. In this proof of concept, a small team at Principled Technologies sought to create a functional chat application with a new, large sample set of data stored in Azure Cosmos DB, using the Vector Search & AI Assistant as our starting point. In the science behind the report, we detail exactly what we did and how we did it, so you can use our work as a starting point for your own application. If you have chosen to develop an intelligent Azure application that uses large language models with your own data, an effective approach is to store your unstructured or document-based data in Azure Cosmos DB, use Azure AI Search as a search and retrieval system, and utilize Azure OpenAI Service for your LLM access. We implemented this application with a custom dataset, proving that it is not only possible but straightforward to built an intelligent AI-powered application using Azure Cosmos DB and other tools from Azure. While our application is specifically a chat application based on the Vector Search & AI Assistant application, Azure Cosmos DB is also suitable for intelligent AI-powered applications beyond the chat realm. Depending on your organization’s specific needs, you may wish to build an application that performs recommendations, one that allows for speedier transactions, or something entirely unique to you.
