Gigabyte R183-S91 Server

Powered by two 4th or 5th generation Intel Xeon Scalable processors with up to 64 cores each, the Gigabyte R183-S91 Server delivers 8x drive bays with different form factors. Four SFF or LFF Gen4 NVMe, SATA, or SAS hot-swappable drive bays line the bottom of the front panel, marked by green tabs. Just above those are 4x SFF 9.5mm Gen4 NVMe, SATA, or SAS hot-swappable drive bays, also marked by smaller green tabs. With both CPUs installed, the R183-S91 server supports 32x DDR5 memory module slots for up to 8TB of memory. This system also supports Intel Optane Persistent 300 series memory modules (PMem).
