Dell PowerEdge R650xs 1U Rack Server

This Dell PowerEdge R650xs is a 1U rack server equipped with two Intel Xeon Silver 4314 processors running at 2.4GHz with 16 cores each. It ships with 64GB of DDR4 2666MHz registered ECC memory and a Dell PERC H745 RAID controller with 4GB NV cache. Eight 1.8TB 10K SAS drives and a quad-port 1GbE OCP 3.0 network card are installed.

Suits virtualisation hosts

This configuration suits buyers who need high core count and redundant power in a single rack unit for virtualisation or cloud workloads. The 64GB memory capacity and SAS storage array support mixed read-write patterns typical of hypervisor environments. Buyers who want more storage bays, GPU acceleration or NVMe boot drives should look at other platforms.

Dual Xeon Silver 4314 16-core processors decide fit

The two Silver 4314 CPUs provide 32 total cores at 2.4GHz base and 3.4GHz turbo, setting the performance ceiling for this server. Workloads that scale across many threads will benefit, while single-threaded applications will not see higher frequencies. The LGA 4189 socket and DDR4 memory limit future upgrades to compatible 3rd Gen Intel Xeon Scalable processors only.

Questions about this item

How do I install the 2.5" SAS drives into the 8-bay front chassis and which step is often missed?

Slide each 1.8TB 10K SAS drive into a front bay until the carrier clicks, then verify the PERC H745 RAID controller detects all eight drives in the BIOS before creating any virtual disks.

What maintenance will the PERC H745 RAID controller's 4GB NV cache battery require over time?

The cache battery on the H745 controller will degrade after several years; replace it when iDRAC 9 Enterprise reports a battery health warning to prevent write-cache data loss during power events.

At what point does the 1400W platinum power supply become the limiting factor under sustained full load?

With two 1400W PSUs providing 1+1 redundancy, the limit is reached when combined CPU, memory, and eight 10K SAS drives draw more than 1400W, causing the second supply to carry the full load.
