PowerEdge R650xs 1U Server

The Dell PowerEdge R650xs is a 1U rack server fitted with two Intel Xeon Silver 4314 processors running at 2.4 GHz with a 3.4 GHz turbo frequency. Each CPU provides 16 cores for a total of 32 cores. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight 16 GB modules and uses an LGA 4189 socket platform.

H745 RAID Controller and 1400 W Power

A Dell PERC H745 front RAID controller with 4 GB NV cache and battery backs RAID levels 0, 1, 5, 6, 10, 50 and 60 for the eight 2.5-inch SAS or SATA drive trays. Dual 1400 W platinum-efficiency hot-swap power supplies provide full redundancy. The bundle also adds a Broadcom 5720 quad-port 1 GbE OCP 3.0 network card, iDRAC9 Enterprise remote management, ready rails and a front bezel.

Suited for Dense Virtualisation and Cloud

This configuration suits organisations running virtualisation, cloud infrastructure or dense data analytics in limited rack space. Buyers who need more storage bays, GPU acceleration for AI workloads or NVMe drive support should look at alternative chassis designs. Those requiring a single-processor layout or lower power draw will also need a different platform.

Questions about this item

What maintenance will the PERC H745 RAID controller battery require over the life of this server?

The PERC H745 includes a 4GB NV cache backed by a battery; the battery is a replaceable component that typically needs replacement every three to five years to preserve write-cache protection.

What thermal or power limit appears first when both Xeon Silver 4314 CPUs run at 3.4 GHz turbo continuously?

Each processor has a 1400 W platinum power supply available; sustained 3.4 GHz turbo on all 16 cores per socket will hit the CPU package power limit before the PSU capacity is reached.

How much heat does the 1U chassis produce and what fan noise level results when the system runs all day?

Dual 1400 W platinum supplies and two 16-core CPUs push significant heat through the 1U chassis; the high-speed fans required for adequate airflow generate noticeable data-centre noise levels.
