PowerEdge R650 1U rack server

The Dell PowerEdge R650 is a 1U rack server equipped with two Intel Xeon Silver 4316 processors. Each CPU runs at 2.3 GHz with a 3.4 GHz turbo frequency and provides 20 cores. The system ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots.

Suits virtualization and database clusters.

This configuration targets virtualization, database management and dense private cloud deployments that benefit from high core counts and large memory capacity. The 1U form factor fits standard rack installations with redundant 1400 W power supplies. Workloads requiring GPU acceleration or more than ten front-accessible drive bays should evaluate alternative platforms.

PERC H755 RAID controller with 8 GB NV cache

Storage is managed by a Dell PERC H755 PCIe controller featuring 8 GB of non-volatile cache and a battery backup unit. It supports RAID 0, 1, 5, 6, 10, 50 and 60 across the ten 2.5-inch SAS and SATA trays. The controller choice determines which drive types and RAID levels are available for the deployment.

Questions about this item

Should I pick the 512GB DDR4 configuration or plan for the 2TB maximum?

The server ships with 512GB installed across 16 slots and supports up to 2TB total, so you can add memory later if workloads grow.

What does the 2.3GHz base and 3.4GHz turbo mean for actual throughput?

Each Xeon Silver 4316 runs at 2.3GHz base and can reach 3.4GHz turbo across its 20 cores, giving 40 cores combined for virtualization and database workloads.

How does the H755 controller with 8GB cache affect RAID performance?

The PERC H755 supports RAID 0, 1, 5, 6, 10, 50 and 60 with 8GB NV cache and battery backup, accelerating both read and write operations on the 10 drive bays.
