Dell PowerEdge R640 10SFF Server

This 1U rack server delivers 24 cores at 3GHz with 256GB DDR4 ECC registered memory in a 10-bay 2.5-inch chassis. It suits virtualisation hosts, database nodes and compute clusters that need dense processing and flexible local storage.

Verify Rack Depth and Power Connections

The unit measures 36 inches deep and weighs 40 pounds so confirm your rack rails and floor loading allow for it. Two 750W supplies are installed; check that your PDU cords and circuit capacity match the dual-feed design before ordering.

Sustained Load with Dual 750W Supplies

Under continuous workloads the redundant 750W power supplies share current to maintain stable voltage across all 24 cores and 16 memory modules. The PERC H740P controller manages up to 10 SATA drives without thermal throttling during extended RAID rebuilds or heavy I/O.

Questions about this item

Does the 10SFF chassis ship with any 2.5" drives or must they be purchased separately?

The 10SFF chassis arrives without any 2.5" drives installed; storage must be sourced and fitted by the buyer.

Should I choose the single 6248R 24C configuration or add a second processor later?

The board supports a second Xeon 6248R; adding it doubles the core count to 48 and raises the memory ceiling to 7.68TB.

How does the 256GB DDR4 ECC registered memory behave under the PERC H740P controller in production?

The 256GB DDR4 ECC registered modules run at native speed with full error correction, feeding the H740P RAID engine without bottleneck.
