Dell PowerEdge R650xs 1U 10-Bay Server

The Dell PowerEdge R650xs is a 1U rack server designed for dense data center deployments. It ships with two Intel Xeon Gold 6338 processors, each running at 2.0 GHz with a 3.2 GHz turbo frequency and 32 cores. The system includes 128 GB of DDR4 3200 MHz registered ECC memory across eight modules. A PERC H745 RAID controller with 4 GB NV cache and battery supports RAID 0, 1, 5, 6, 10, 50, and 60.

Suited for virtualization

This server suits buyers who need high core counts and redundant power in a 1U form factor. The dual 1400 W platinum power supplies and iDRAC9 Enterprise provide reliability and remote management. Builders who require more than two processors, memory beyond 1 TB, or drive bays beyond the ten 2.5-inch trays should look elsewhere. The included quad-port 1 GbE OCP 3.0 card may not meet needs for higher-speed networking.

PERC H745 RAID controller with 4 GB NV cache

The storage controller determines which drive types and RAID levels are supported. The H745 handles SATA and SAS drives on the ten front trays and provides battery-backed cache for write performance. Buyers planning to use NVMe drives or needing a different RAID feature set must verify controller compatibility before purchase.

Questions about this item

Should I pick the 10-bay 2.5-inch model or a version with fewer drive slots?

The 10-bay 2.5-inch configuration fills the 1U chassis completely, giving the highest local storage density for this platform. If your workload needs many SAS or SATA drives in minimal rack space, this is the version to choose.

What does the 3.2 GHz turbo figure mean when the server is running a full load?

Each Gold 6338 processor can boost from its 2.0 GHz base up to 3.2 GHz on active cores, so single-threaded or lightly threaded tasks see the higher clock while all-core workloads settle nearer the base frequency.

How does the OCP 3.0 network card limit real-world throughput?

The Broadcom 5720 card provides four 1 GbE ports over an OCP 3.0 slot, so aggregate bandwidth tops out at 4 Gbps and cannot exceed the 1 Gbps per-port ceiling.
