DELL PowerEdge R650xs 1U rack server 2x Xeon Silver 4316 2.3GHz 20-core 64GB DDR4 H745 8x 1.8TB SAS

PowerEdge R650xs 1U server

This Dell PowerEdge R650xs is a 1U rack server built for dense compute environments. It ships with two Intel Xeon Silver 4316 processors running at 2.3GHz with 20 cores each and 64GB of DDR4 2666MHz registered ECC memory across four modules. The system includes a PERC H745 RAID controller with 4GB NV cache, eight 1.8TB 10K SAS drives, dual 10GbE SFP+ networking, iDRAC9 Enterprise, and redundant 1400W platinum power supplies with rails and bezel.

Suits virtualization hosts needing maximum CPU

This configuration targets workloads that demand high core counts and fast local storage within a single rack unit. Virtualization clusters, database nodes, and HPC head nodes benefit from the 40 combined cores and hardware RAID across eight SAS spindles. Buyers who need GPU acceleration, NVMe boot devices, or more than 1TB of memory should evaluate other platforms since this unit has no GPU risers, no NVMe backplane, and a 1TB memory ceiling.

PERC H745 RAID controller

The H745 controller governs how the eight 1.8TB SAS drives are presented to the operating system with support for RAID 0, 1, 5, 6, 10, 50, and 60. Its 4GB non-volatile cache with battery backup protects in-flight writes during power loss. This single component determines whether the array can sustain the random IOPS your workload requires or whether a different controller or drive type would be necessary.
