DELL PowerEdge R650xs 1U Rack Server 2x Xeon Gold 5317 3.0GHz 12-Core 64GB DDR4 8x 600GB SAS H745 2x 1400W PSU

Dense 1U compute node

The Dell PowerEdge R650xs is a 1U rack server built for high-density compute. It ships with two Intel Xeon Gold 5317 processors running at 3.0 GHz with 3.6 GHz turbo across 12 cores each. Memory is 64 GB of DDR4-2933 registered ECC in a four-module layout. Storage uses a PERC H745 controller with 4 GB NV cache driving eight 600 GB 10K SAS drives. A quad-port 1 GbE OCP 3.0 card and iDRAC9 Enterprise handle networking and remote management. Dual 1400 W platinum power supplies, rails and bezel are included.

Buyers needing more internal drive bays

The 1U chassis limits internal storage to eight 2.5-inch bays and restricts add-in card space. Teams that require larger drive counts, GPU accelerators or multiple high-speed network adapters should evaluate a 2U or larger platform. Workloads that depend on 10 GbE or faster networking will need an additional OCP card. Memory can scale to 1 TB across 16 DIMM slots if the application demands it.

PERC H745 with 4 GB NV cache

The front-mounted PERC H745 RAID controller provides 4 GB of non-volatile cache backed by a battery. It supports RAID 0, 1, 5, 6, 10, 50 and 60 for the eight SAS drives. This controller choice determines the RAID levels available and the write-performance ceiling for the configured storage.
