Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rackmount server built for dense scale-out deployments. Two Intel Xeon Gold 6142 processors run at 2.6 GHz with 16 cores each, delivering 32 cores total. Memory ships as 256 GB of DDR4 2666 MHz registered ECC across 8 modules, leaving 16 of 24 slots free for expansion.

Storage-focused buyers vs network-heavy workloads

The eight 2.5-inch drive bays connect to a PERC H730P RAID controller with 2 GB cache, supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through. Two 300 GB 10K SAS drives are installed. A quad-port daughter card adds two 1 GbE and two 10 Gb SFP+ links. Buyers who need more than eight drive bays or a different network interface count should look elsewhere.

PERC H730P SAS controller decides fit

The storage controller is a Dell PERC H730P 2 GB 12 Gb/s SAS/SATA adapter with battery-backed cache. It governs which drives can be used and which RAID levels are available. Confirm that your drive type and RAID requirements match this controller before purchase.
