Dell PowerEdge R640 4LFF server

The Dell PowerEdge R640 is a 1U rack server built for virtualisation, database and general compute workloads. It ships with one Intel Xeon Silver 4210 processor running at 2.2 GHz and 256 GB of DDR4 ECC registered memory across sixteen 16 GB modules. A second processor socket is available for future expansion.

Tool-less rails and iDRAC9 simplify setup

The chassis supports tool-less rail installation and the integrated iDRAC9 Enterprise licence enables full remote deployment, monitoring and firmware updates without physical access. The PERC H740P RAID controller manages up to four 3.5-inch SATA drives; cable routing and backplane alignment are the most common points to verify during initial build.

256 GB DDR4 with 7.68 TB ceiling

The current 256 GB configuration handles moderate virtualisation clusters and in-memory databases comfortably. Maximum supported capacity reaches 7.68 TB when both processor sockets are populated and all DIMM slots are filled, providing extensive headroom for growth. Storage capacity depends on the four 3.5-inch drive bays and the selected SATA drives.

Questions about this item

How do I confirm the server is working correctly after initial setup?

After powering on, watch the front-panel LCD for the POST sequence to complete without error codes, then log into the iDRAC9 Enterprise interface and verify the System Event Log shows no critical alerts and all 256GB of DDR4 memory is reported.

What components are included and what must I supply?

The chassis ships with one Xeon Silver 4210 2.2GHz 10-core processor, 256GB DDR4 ECC registered memory in sixteen 16GB modules, a PERC H740P RAID controller, a dual-port 10GbE 562T adapter, two 750W power supplies and four empty 3.5-inch drive bays; you must provide SATA hard drives or SSDs and, if desired, a rail kit.

Which configuration should I choose for maximum memory headroom?

The installed 256GB uses all sixteen DIMM slots on the single processor; to expand toward the 7.68TB maximum you would need to add a second Xeon Silver 4210 processor, which unlocks the remaining sixteen slots for additional DDR4 modules.
