DELL PowerEdge R640 4LFF 1x Xeon Gold 6244 128GB DDR4 rack server

Dell PowerEdge R640 4LFF for dense storage workloads

This 1U rack server fits four 3.5-inch drive bays and a single Xeon Gold 6244 processor running at 3.6 GHz with 128 GB of DDR4 ECC registered memory. It targets organisations that need local capacity in a compact footprint for databases, virtualisation hosts or backup repositories. Buyers who want more storage bays or dual-socket compute density should consider larger chassis options.

SATA interface and PERC H740P controller set

The installed PERC H740P RAID controller manages drives over a SATA interface, so throughput is bounded by that link speed rather than by faster protocols. The chassis supports a maximum of four 3.5-inch drives, capping raw capacity at the number of bays multiplied by the largest drive you install. The single processor configuration leaves one socket empty, limiting total core count and maximum memory to half the platform ceiling of 7.68 TB.

Tool-less rails and iDRAC9 simplify deployment

The server slides into a standard rack on tool-less rails that are available on request, and the iDRAC9 Enterprise licence gives full remote console, power control and firmware update access over the network. The two 750 W power supplies are hot-pluggable, so a failed unit can be swapped without downtime. Common issues arise when drive carriers are not fully seated or when the RAID configuration is not initialised before the operating system install begins.
