Gigabyte Server launched a new 2U single socket AMD EPYC platform. The Gigabyte R271-Z00 uses a few components we have seen before. The AMD EPYC platform has expansive single socket capabilities alongside extremely aggressive CPU pricing. That gives the platform a clear advantage over Intel in this segment on a price performance basis.
Gigabyte R271-Z00 Overview
The basis of the Gigabyte R271-Z00 is a single socket motherboard. Onboard there are four slim SAS connectors that are used for SATA III 6.0gbps ports. These utilize SATA cabling but are designed to only use SATA III here. These connect to the twelve front 3.5″ storage bays. The AMD EPYC socket is flanked by eight DDR4 DIMM slots with support for up to 1TB of memory using 128GB DIMMs. A key feature of this platform is the PCIe slot configuration. There are four PCIe 3.0 x16 slots along with a PCIe 3.0 x8 slot. All of these low profile slots have the full electrical capability which provides 72 PCIe lanes along with four more for the M.2 slot for a total of 76 lanes. This is far more than the Intel Xeon Scalable Skylake-SP has in a single socket configuration (maximum 48 from the CPU.)
If you saw our recent Ultra EPYC platform, we used a sister motherboard to what is used in the Gigabyte R271-Z00. The Ultra EPYC utilized a Gigabyte MZ01-CE0 which has onboard dual 1GbE and dual 10GbE. The Gigabyte R271-Z00 utilizes the MZ01-CE1 which does not have the 10GbE.
The rear of the chassis has dual redundant 550W power supplies, as well as two 2.5″, hot-swap bays. These 2.5″ rear bays are popular for OS boot and caching applications. The M.2 drive slot along with the other PCIe slots provide ample room for NVMe caching. We, therefore, think the 2.5″ bays will be used mostly for the OS.
A Familiar Note
One will notice a familiar strategy in play. The motherboard used here is the same one that can be found in the Gigabyte W291-Z00 AMD EPYC GPU tower. Gigabyte is using a standard ATX form factor and proliferating the motherboard design to different chassis and using it for multiple applications.
