GIGABYTE Releases GPU-centric Servers for 8+ Accelerators and 160 PCIe Lanes

Verfasst vonpipin

Desi­gned for Dual 2nd Gen AMD EPYC Architecture

Tai­pei, Tai­wan, Novem­ber 12th 2020 – GIGABYTE Tech­no­lo­gy, (TWSE: 2376), an indus­try lea­der in high-per­for­mance ser­vers and work­sta­tions, today announ­ced three new GPU-cen­tric ser­vers (G482-Z53, G482-Z54, and G292-Z43) aimed at HPC, AI, sci­en­ti­fic simu­la­ti­on and mode­ling, and more. Using AMD EPYC™ archi­tec­tu­re, rea­li­zing eight GPUs in PCIe Gen 4 x16 lanes is pos­si­ble, while main­tai­ning room for sto­rage and net­wor­king. The G482-Z53, G482-Z54, and G292-Z43 are desi­gned for eight or more GPUs, but have space available for sto­rage, net­wor­king, or other accelerators.

Impro­ved Acce­le­ra­tor Performance:
All three new ser­vers can run all their PCIe Gen 4 lanes to func­tion at x16, which means the­re can be as many as 160 PCIe lanes available, and they all have a theo­re­ti­cal band­width of 32 GB/s for fast com­mu­ni­ca­ti­on bet­ween CPU and GPU. This is made pos­si­ble by AMD EPYC 7002 archi­tec­tu­re that allows a sin­gle socket-to-socket Infi­ni­ty Fabric link (one of four) to real­lo­ca­te the band­width to PCIe lanes for other pur­po­ses. This is pos­si­ble becau­se a dual AMD EPYC 7002 sys­tem uses 64 PCIe lanes from each CPU to link to the adja­cent CPU. By free­ing up one of the­se four links, 16 lanes per CPU can be redi­rec­ted for fast PCIe Gen 4 speeds in sto­rage, acce­le­ra­tors, or networking.

G482-Z54

Intro­duc­tion to the G482-Z53 and G482-Z54:
Incre­di­bly, the G482-Z53 and G482-Z54 are built for 8 x GPUs, such as the AMD Instinct™ MI50, slot­ted next to each other and lin­ked via the AMD Infi­ni­ty Fabric link. The­se ser­vers have been tes­ted and desi­gned for AMD Instinct MI50 and other acce­le­ra­tors. The ser­vers uti­li­ze dual AMD EPYC 7002 pro­ces­sors ope­ra­ting with 128+ PCIe Gen 4 lanes. Reco­gni­zing the full poten­ti­al of high band­width PCIe Gen 4 lanes, the 2nd Gen AMD EPYC pro­ces­sors are capa­ble of real­lo­ca­ting band­width dedi­ca­ted to CPU to CPU con­nec­ti­vi­ty to be redi­rec­ted for acce­le­ra­tors and net­wor­king. What is even more impres­si­ve is that all GPUs have their own dedi­ca­ted PCIe Gen 4 x16 lanes, wit­hout the use of a PCIe switch to share a sin­gle lane with two GPUs. All G482 ser­vers ful­ly sup­port up to 280W 2nd Gen AMD EPYC pro­ces­sors, 32 DIMMs, 3200MHz DDR4, and 128GB memo­ry modu­les. The G482 series of ser­vers have some key dif­fe­ren­ces, as seen in the fol­lo­wing table.

Intro­duc­tion to the G292-Z43:
The G292-Z43 is GPU (sin­gle slot) den­si­ty pushed to the max. In a 2U chas­sis, dual AMD EPYC 7002 pro­ces­sors allow for 16 DIMMs of DDR4 memo­ry up to 3200MHz, and in 128GB memo­ry modu­les. With this GPU cen­tric design, sup­port for EPYC 7002 series pro­ces­sors is for models that have a TDP up to 240W. Kee­ping with the importance of PCIe lanes, the G292-Z43 adds sup­port for 16 low pro­fi­le acce­le­ra­tors using PCIe swit­ches. This allows for future expan­si­on or expan­ded networking.
