Space-efficient 1U rack server

The Dell PowerEdge R650xs packs dual Intel Xeon Silver 4314 processors and 256GB of DDR4 memory into a single rack unit. Ten front-access 2.5-inch drive bays provide dense storage in a compact form factor. This configuration targets virtualization hosts and cloud infrastructure nodes where rack space is at a premium.

SAS 12Gb/s controller and 1GbE networking

The PERC H745 RAID controller manages the ten 1.8TB 10K SAS drives with 4GB of non-volatile cache and battery backup, supporting RAID levels up to 60. The Broadcom 5720 OCP 3.0 card delivers four 1GbE ports for standard network connectivity. Storage throughput and network bandwidth are bounded by these interfaces.

Upgrades from older 1U platforms

This system replaces earlier single-socket or lower-core-count 1U servers when workloads demand 32 total cores and 256GB of registered ECC memory. The jump is worthwhile for consolidation projects that need more virtual machines per rack unit. Buyers requiring GPU acceleration or 25GbE networking should evaluate other configurations.

Questions about this item

Should I choose the 10-bay 2.5-inch version or a different drive-count model?

This unit ships with 10 bays populated by 1.8 TB 10 K SAS drives on a H745 controller supporting RAID 0/1/5/6/10/50/60, so capacity and redundancy are fixed by that configuration.

What does the 2.4 GHz base clock with 3.4 GHz turbo mean for actual workloads?

Each Xeon Silver 4314 has 16 cores at 2.4 GHz base and 3.4 GHz turbo, giving 32 total cores for virtualization, databases or HPC tasks that scale across threads.

How does the OCP 3.0 5720 quad-port 1 GbE card limit network throughput?

The Broadcom 5720 provides four 1 GbE ports on an OCP 3.0 module, capping each link at 1 Gb/s and the aggregate at 4 Gb/s unless you add a faster mezzanine card.
