Summary
Hyperconverged infrastructure is changing the way that IT organizations deliver resources to their users. In this short joint reference document with Dell Technologies and Intel we discuss the critical hardware components needed to successfully deploy vSAN. The information in this publication is provided as is. Dell Inc. makes no representations or warranties of any kind with respect to the information in this publication, and specifically disclaims implied warranties of merchantability or fitness for a particular purpose.
The surge in remote work and virtual desktop infrastructure (VDI) is increasing resource demands in the data center. As a result, many enterprises are turning to hyperconverged infrastructure (HCI). But HCI implementation can be complex and time-consuming. VMware vSAN ReadyNode™ provides a turnkey solution for accelerating HCI.
vSAN ReadyNode is a validated configuration on Dell EMC™ PowerEdge™ servers. These servers are tested and certified for VMware vSAN™ deployment, jointly recommended by Dell and VMware. vSAN ReadyNode on Dell EMC PowerEdge servers can help reduce HCI complexity, decrease total cost of ownership (TCO), scale with business needs and accommodate hybrid-cloud solutions such as VMware Cloud Foundation™. Benefits include the following:
- License efficiency—Get the most from each software license. vSAN ReadyNode on Dell EMC PowerEdge servers is designed to provide the best performance for each VMware® license per 32-core socket.
- High throughput—Elastic, scalable storage is one of many vSAN benefits. vSAN ReadyNode on Dell EMC PowerEdge servers, built on high-performing Intel architecture, prioritizes storage throughput with fast write caching and capacity storage tiers.
- Low latency—As a vSAN deployment grows, and data needs to be accessed across the cluster, data-access response times become increasingly important. This architecture, featuring Intel Ethernet Network Adapters, takes advantage of VMware’s recent addition of remote direct memory access (RDMA) to improve data response and user experience.
Key Considerations
- Available in two configurations—Both the “Base” and “Plus” configurations use similar all-flash NVM Express® (NVMe®) storage configurations. However, the Plus configuration is equipped with a higher-frequency CPU and Intel® Optane™ persistent memory (PMem). Both configurations are based on Intel® Select Solutions for VMware vSAN 7 HCI with 3rd Generation Intel® Xeon® Scalable processors.
- Networking—Both configurations are equipped with RDMA-capable Intel® Ethernet 800 Series network adapters that accelerate vSAN 7 performance (7.0 U2 or later). The Intel Ethernet Network Adapter E810- XXV network interface controller (NIC) can be used for network- and storage-intensive workloads requiring more than 25 gigabits per second (Gbps) of bandwidth.
- Rack-space requirements—The rack-space-optimized Dell EMC PowerEdge R650 server–based system can be used if large storage capacity is not needed (up to two storage groups are supported, each with a single cache drive and up to four capacity drives, with a maximum of 10 NVMe drives per system). For more drives or future- capacity scaling, the Dell EMC PowerEdge R750 server–based system is recommended.

Test Report: PowerEdge R760 with vSAN
Fri, 03 Mar 2023 17:20:50 -0000
|Read Time: 0 minutes
Summary
The testing outlined in this paper was conducted in conjunction with Intel and Solidigm. Server hardware was provided by Dell, processors and network devices were provided by Intel, and storage technology was provided by Solidigm. All tests were conducted in Dell Labs with contributions from Intel Performance Engineers and Dell System Performance Analysis Engineers.
VMware ESXi is one of the most widely deployed hypervisor solutions in the world, and many customers using ESXi choose vSAN as the strategic storage solution for their virtualized environments. Because the combination of ESXi and vSAN forms a strategic pillar of their IT infrastructure, it is critical that customers keep them current by deploying upgrades and patches throughout their life cycle. ESXi 7 has been the standard upon which customer deployments of the last two generations of Dell PowerEdge servers have relied, but with the release of the new ESXi 8 and vSAN 8, customers must make a choice: Upgrade their old hardware with these new releases or transition to these new releases using the latest generation of servers from Dell Technologies.
Transitioning between major releases of software can be challenging. vSAN 8, for example, offers a completely new architecture called “Express Storage Architecture.” This technology is designed to increase performance, reliability, and manageability, but it requires a different, more current hardware architecture. Upgrading old hardware with this new environment can add risk and complexity, and can result in compatibility issues that could cause unwanted downtime. The solution for many customers is to deploy the new hypervisor and vSAN architecture on new hardware and then work to transition the virtual machines from their existing environment to their new environment. Making the deployment easier, the release of ESXi 8 and the corresponding vSAN 8 coincides with the announcement of Dell’s next generation of servers based on the new 4th Gen Intel® Xeon® processors. To facilitate the transition, Dell and Intel have worked together to profile the performance of PowerEdge R750 running ESXi 7.0U3 and vSAN 7.0U3 and then contrast the results with the performance of the new PowerEdge R760 running ESXi 8 with vSAN 8.0.
Note: While the Express Storage Architecture is expected to increase performance even further, we conducted our testing using the legacy vSAN disk configurations. This paper highlights the findings of that testing.

Deliver Business Insights Faster with Microsoft SQL Server 2019 and VMware vSAN™
Tue, 17 Jan 2023 07:07:32 -0000

Summary
This joint paper outlines a brief discussion on the key hardware considerations when planning and configuring a VMware vSAN™server configuration. Including sample PowerEdge server configurations for a starting deployment and quoting process.
Today’s enterprises need to move fast to stay competitive. For example, high- speed transactional processing solutions accelerate insights for financial trading or wholesale supply. High-speed analytics solutions enable users to quickly identify patterns in customer behavior or resource usage to inform better predictions and forecasts.
IT professionals are on point to deliver this high-performance data while reducing infrastructure costs. That is why IT pros choose Microsoft SQL Server 2019 running on VMware vSAN™.
They also choose Dell EMC™ PowerEdge™ rack servers configured with the latest generation of Intel® technologies. What are the benefits?
- Selecting SQL Server 2019 enables IT pros to deliver industry leading performancei.
- Adopting hyperconverged infrastructure (HCI) powered by vSAN, combined with VMware vSphere®, enables IT pros to manage compute and storage with a single platform that lowers infrastructure costs when compared to traditional three-tier architecturesii.
- Dell EMC PowerEdge servers running vSphere boost the orders per minute (OPM) of transactional databases more than 1.9 timesiii, and they allow users to complete 8x the analytics in 39 percent less timeiv, when compared to previous-generation servers.
Key Considerations
To get started, available server configurations for SQL server 2019 are shown in the “Available Configurations” section below. Key considerations include the following:
- CPU: High-frequency 3rd Generation Intel® Xeon® Scalable processors with 2.8 GHz clock speeds help optimize performance by enabling SQL Server 2019 locks to be released more quickly so multiple processes can access data faster. Additionally, Dell Technologies recommends using multiples of 24 CPU cores to make it easier to segment vSAN clusters and match the licensing structure of SQL Server 2019 Standard edition.
- Memory and Storage: The Base configuration can be set up with two storage groups and up to eight capacity drives, while the Plus configuration can be equipped with up to four storage groups and up to 12 capacity drives. In general, using more storage groups provides better write performance.
Dell Technologies recommends 1 TB of Intel® Optane™ persistent memory (PMem) 200 series per node. Intel Optane PMem creates a larger memory pool that enables SQL Server 2019 to run faster because data can be read from logical, in-memory storage, as opposed to a physical disk. For storage, Dell recommends using Intel Optane Solid State Drives (SSDs) for caching frequently accessed data. The Intel Optane SSD P5800X is the world’s fastest data center SSDv. PCIe® Gen4 NAND SSDs are recommended for the capacity tier.
- Networking: The configuration specifies Intel® Ethernet 800 Series network interface controllers (NICs) with Remote Direct Memory Access (RDMA), a hardware-acceleration feature that reduces the load on the CPU. Intel Ethernet 800 Series NICs start at 10 gigabit Ethernet (GbE) and scale up to 100 GbE. With Intel Ethernet 800 Series NICs, you will notice faster data speed between vSAN clusters, which becomes more important as node counts grow.
Available Configurations
The Plus configuration includes more cores, memory, and storage to support more or larger SQL Server 2019 instances and provide better performance.
