DELL PowerEdge R640 1U rack server 2× Xeon Gold 5118 2.3GHz 12-core 256GB DDR4 H730P 2× 400GB SSD

Dual-socket 1U compute density

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules and a Dell PERC H730P RAID controller with 2 GB cache. Two 400 GB SATA SSDs provide initial storage in an 8-bay 2.5-inch chassis.

Scale-out workloads versus expansion limits

This configuration suits dense virtualisation, cloud or HPC clusters that benefit from 24 cores and 256 GB RAM in a single rack unit. The 8-bay front panel and single PERC H730P controller cap internal drive count at eight SATA or SAS devices. Buyers who need more internal bays, a second RAID controller or GPU compute should evaluate larger form-factor platforms.

PERC H730P RAID capability

The installed Dell PERC H730P 2 GB controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes, backed by a battery for write-cache protection. It manages the two 400 GB SATA SSDs and any additional SATA or SAS drives populated in the remaining six bays. This controller choice determines the RAID levels and maximum drive count available without adding hardware.
