In our data center, we tested two VMware vSphere 7.0 Update 1 cluster configurations with VMware vSAN™:
Each server featured 256 GB of RAM, one BOSS card with two 480GB M.2 SSDs for the hypervisor, and six PCIe 4.0 NVMe SSDs. We configured each node of the vSAN cluster with two 1.6TB mixed-use drives for the caching tier and four 1.92TB read-intensive drives for the capacity tier. We measured the performance of each cluster using a virtualized MongoDB database and Workload C of the YCSB tool, which consists entirely of read operations. We ran a four-node vSphere cluster for each solution, with each node hosting four MongoDB VMs, each with a 32GB database for a total of 16 MongoDB VMs. We deployed 64 YCSB driver VMs on separate hardware to run Workload C against the MongoDB VMs. We ran this workload three times on each cluster and identified the median OPS result of the three runs. To calculate a performance-per-dollar ratio for each solution, we divided the operations per second output by the price for hardware and support above. For more details on our test process and configurations, see the science behind the report.
According to Dell Technologies, these single-socket 1U servers offer the following high-level specifications:

These 32-core processors use AMD Infinity Architecture and are part of the AMD EPYC 7003 Series. The latest offering from AMD, 3rd Gen EPYC processors offer increased I/O with “up to 32MB L3 cache per core,” 7nm x86 technology, and new security features like Secure Encrypted Virtualization - Secure Nested Paging (SEV- SNP) and Encrypted State (SEV-ES).5 AMD positions the EPYC 75F3 model as being well suited for high frequency use cases such as VM density, virtualization, and VDI.6

2 We received an itemized Dell EMC PowerEdge R6515 list price quote from Dell Technologies with the AMD EPYC 7542 processor. To calculate the price of the newer solution, we removed the cost of the AMD EPYC 7542 processor and added the pre-release list price for the AMD EPYC 75F3 processor we received from Dell Technologies.
