Dense compute in 1U

The PowerEdge R650xs packs two Intel Xeon Silver 4314 processors into a single rack unit, delivering 32 cores at 2.4 GHz with 3.4 GHz turbo. It targets virtualisation clusters, cloud infrastructure and dense analytics workloads that demand high thread count within minimal rack space.

DDR4 ceiling and drive bay limit

Memory tops out at 1 TB across 16 DDR4 slots running up to 3200 MT/s, so large in-memory datasets cannot scale beyond that boundary. The chassis provides only ten 2.5-inch SAS/SATA trays, restricting local storage device count regardless of drive capacity.

Dual Silver 4314 CPUs define the performance

With two 16-core Xeon Silver 4314 chips installed, the server fixes its maximum compute throughput at 32 cores and 256 GB of registered ECC DDR4-2666. Buyers needing more cores, higher per-core frequency or larger memory capacity must choose a different configuration.

Questions about this item

Should I pick the 256GB DDR4 configuration or the 1TB maximum capacity?

The server ships with 256GB of DDR4 2666MHz registered ECC memory installed. The platform supports up to 1TB across 16 DIMM slots, so you can expand later if workloads demand more capacity.

What does the 2.4GHz base clock with 3.4GHz turbo mean for actual workloads?

Each Xeon Silver 4314 runs at 2.4GHz base and can boost to 3.4GHz under load. With two 16-core processors installed, you get 32 cores total for parallel tasks such as virtualization, databases or dense compute.

How does the PERC H745 controller with SATA/SAS interface affect drive performance?

The H745 RAID controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with 4GB NV cache. It manages the 10 front 2.5-inch SAS or SATA drive bays, so throughput is limited by the drive media and the controller's cache rather than a raw interface ceiling.
