Taipei, Taiwan, 11 April 2018 – GIGABYTE, an industry leader in competitive, high performance server motherboards and systems, has refreshed its AMD EPYC™ 1U and 2U server line-up with a range updated options supporting different storage device combinations, with increased NVMe connectivity to integrate more dense, high bandwidth storage.

These five systems are part of GIGABYTE’s ready-to-integrate general purpose Rack Server family, equipped with the best power supplies and cooling fans and combining a high level of performance, energy efficiency and overall reliability for web hosting, mass storage, virtualized infrastructures, databases & analytics and other demanding applications.

GIGABYTE’s AMD EPYC™ server systems are based on the 7000 series EPYC™ processor, offered as a SoC and incorporating a multi-die design with 32 cores per processor, 128 PCIe lanes and 8 channels of DDR4 memory. These features have allowed GIGABYTE to create a range of servers that pack a real punch in flexibility and expansion options. First released in July last year, adoption of GIGABYTE’s AMD EPYC™ servers has been gaining momentum, lowering TCO for datacenters by offering an optional balance of compute, memory, I/O and security.

The five refreshed GIGABYTE AMD EPYC™ server products are: the 1U form factor R181-Z90, R181-Z91 and R181-Z92, and the 2U form factor R281-Z91 and R281-Z92.

These five systems all support dual AMD EPYC™ 7000 series processors with 32 DIMM slots. Storage wise, the R181-Z90 supports 4 x 3.5" hot-swap SATA/SAS drives, the R181-Z91 supports a mix of 2 x 2.5" hot-swap NVMe U.2 drives and 8 x hot-swap 2.5” SATA/SAS drives, while the R181-Z92 supports 10 x 2.5" hot-swap NVMe U.2 drives.

Meanwhile, the R281-Z91 supports a mix of 6 x 2.5" hot-swap NVMe U.2 and 20 x 2.5" hot-swap SATA/SAS drives, and the R281-Z92 supports 24 x 2.5" hot-swap NVMe U.2 + 2 x 2.5” hot-swap SATA/SAS drives. These five systems also all feature 1 x NVMe M.2 slot for an additional ultra-fast storage device.

Systems that support more dense, high-bandwidth storage can extremely suited for applications such as Big Data, where memory size and performance to store these large volumes of data during processing is becoming more and more important.

A comparison of the main specifications of each model can be found in the following table:
