PowerEdge R650 compute density

This 1U rack server fits two Intel Xeon Silver 4316 processors and 768GB of DDR4 memory into a single rack unit. Twenty cores per CPU run at 2.3GHz with a 3.4GHz turbo frequency. The system targets virtualization, database and dense cloud workloads that demand high core counts in minimal space.

Storage-constrained buyers

Ten 2.5-inch bays hold 1.8TB 10K SAS drives managed by a PERC H755 controller with 8GB NV cache. The array supports RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need more raw capacity or NVMe speed should look at a platform with larger bays or additional drive slots.

PERC H755 RAID controller

The installed Dell PERC H755 PCIe card provides hardware RAID across all ten SAS drives and includes a battery-backed 8GB cache. This single component determines both data protection options and sustained write performance for the entire server.

Questions about this item

Does the 2 x Intel Xeon Silver 4316 2.3GHz 20-core processors require a specific operating system to use all 40 cores?

The processors present 40 cores total to any modern server OS; Windows Server, Linux and hypervisors such as VMware ESXi will schedule across all cores without extra licensing steps.

Can the Dell PERC H755 controller manage the 10 x 1.8TB SAS drives together with older SATA SSDs I might keep?

The H755 supports mixed SAS and SATA drives in the same chassis; you can create separate virtual disks for each media type or blend them in a single array if performance parity is acceptable.

How can I confirm the 768GB DDR4 2666MHz memory is running at the correct speed after installation?

Check the iDRAC9 Enterprise inventory or the BIOS memory information screen; both will report each DIMM at 2666 MT/s and show 768 GB total with ECC active.
