PowerEdge R650 1U 10-Bay Server

The Dell PowerEdge R650 is a 1U rack server designed for dense compute environments. It ships with dual Intel Xeon Silver 4316 processors, each providing 20 cores at 2.3 GHz with 3.4 GHz turbo. The system includes 256 GB of DDR4 2666 MHz registered ECC memory across eight 32 GB modules. Dual 1400 W platinum power supplies and iDRAC9 Enterprise management complete the platform.

Virtualisation and database clusters

This configuration suits workloads that demand high core counts and fast local storage in a single rack unit. The 10-bay SAS array with hardware RAID supports mixed read-write patterns typical of databases and virtualised infrastructure. Organisations needing GPU acceleration, larger memory footprints beyond 256 GB, or all-flash NVMe arrays should evaluate alternative chassis or drive configurations.

PERC H755 RAID controller with 8 GB NV cache

The installed Dell PERC H755 PCIe controller manages the ten 1.8 TB 10K SAS drives and supports RAID 0, 1, 5, 6, 10, 50 and 60. Its 8 GB non-volatile cache with battery backup protects in-flight writes during power loss. This single component determines the achievable storage performance, data protection level and rebuild behaviour for the entire array.

Questions about this item

Does the server ship with all ten 1.8 TB SAS drives and the H755 RAID controller already installed?

Yes, the R650 includes ten 1.8 TB 10K SAS drives and a PERC H755 controller with 8 GB NV cache and battery, supporting RAID 0/1/5/6/10/50/60.

Should I choose the dual Silver 4316 configuration or a single processor for lighter workloads?

The unit comes with two Silver 4316 CPUs, each 20 cores at 2.3 GHz with 3.4 GHz turbo, giving 40 cores total; a single-CPU version is not offered in this listing.

What does the 256 GB DDR4-2666 figure mean for actual virtualization density?

The server has 256 GB (8 × 32 GB) of registered ECC DDR4 running at 2666 MT/s, expandable to 2 TB across 32 DIMM slots for dense VM hosting.
