AMD EPYC 7371 Test Configuration
- CPU: AMD EPYC 7371
- Server Barebones: Tyan Transport SX TN70A-B8026 (B8026T70AE24HR)
- RAM: 8x 16GB 128GB DDR4-2666 RDIMMs (Samsung)
- SSD: 1x Intel DC S3710 400GB SATA SSD, Intel Optane 905p 480GB
- NIC: 1x Mellanox ConnectX-3 Pro
Longtime STH readers will notice that we added an Intel Optane 905p 480GB NVMe SSD to this configuration. This was specific to some of the additional testing we are doing on this part using the STH web infrastructure. This is somewhat selfish, I wanted to see what the impact would be for our hosting infrastructure. Those results ended up being interesting enough that they made the cut for this review.
Key to this system is that it supports 24x NVMe U.2 NVMe SSDs without using Broadcom PLX PCIe expanders. That is 96 lanes of PCIe 3.0 directly from a single SKU. One of the key advantages AMD EPYC has is that a single EPYC CPU can use 128x PCIe lanes, the same number as the dual socket configuration. Tyan has responded to this opportunity by offering a single-socket system that can handle 24x NVMe drives plus have I/O available for 10/25/40/50/100GbE.
AMD and Tyan originally suggested that we use a Samsung SSD (as pictured), however, to aid in consistency, we are using our lab standard Intel DC S3710 400GB SSDs.
This is a great system that has worked well over the past several quarters. If you have an existing Intel Xeon E5 V1-V4 installation, it is likely that a single socket AMD EPYC 7000 series machine using NVMe drives can replace a dual socket or multiple dual socket previous generation servers. We have seen companies consolidate as many as four dual socket Intel Xeon E5-2620 V1 servers into a single AMD EPYC 7000 series server which is a great consolidation saving.
Next, we are going to benchmark the AMD EPYC 7371 before moving onto our market positioning and final thoughts.
