DELL PowerEdge R640 4x3.5" 2x Xeon Gold 5218 128GB DDR4 No Drive

Dell PowerEdge R640 dual Xeon server

This Dell PowerEdge R640 is a 1U rackmount server system equipped with two Intel Xeon Gold 5218 processors running at 2.3GHz. It ships with 128GB of DDR4 ECC registered memory installed across the available slots. The chassis supports up to four 3.5-inch drive bays for SATA hard drives, though no drives are included in this configuration. It is built for organisations that need dense compute in a single rack unit.

PERC H740P RAID and 10GbE networking

A Dell PERC H740P RAID controller manages the four SATA drive bays, providing hardware RAID levels for data protection. Network connectivity comes from a dual-port 10GbE 562T adapter for high-throughput links. Remote management is handled by iDRAC9 with an Enterprise licence, allowing full out-of-band control. Dual 750W power supplies deliver redundancy, and a rail kit is available on request for rack installation.

Memory ceiling and drive bay limit

The platform supports a maximum memory capacity of 7.68TB of DDR4, giving headroom for future expansion beyond the installed 128GB. Only four 3.5-inch bays are available, so storage density is constrained compared to 2.5-inch chassis variants. The integrated graphics and single-socket-width design limit GPU acceleration options. Buyers needing more than four drives or GPU compute should evaluate alternative configurations.
