Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Silver 4110 processors, each running at 2.1GHz with eight cores. It arrives with 768GB of DDR4 registered ECC memory installed across 24 slots. The chassis includes eight 2.5-inch drive trays, a PERC H730P storage controller and redundant 750-watt platinum power supplies.

Virtualisation Hosts and Scale-Out Workloads

This configuration suits organisations running dense virtualisation, database or high-performance computing clusters that need maximum compute per rack unit. Buyers who need installed storage drives should look elsewhere, as the bays ship empty. Teams requiring more than two processors or a taller form factor will need a different platform.

24 DIMM Slots Supporting 3TB Maximum Memory

The motherboard provides 24 DDR4 slots with a 3TB ceiling, so the installed 768GB leaves ample headroom for future expansion. This single figure determines whether the server can grow with your workload or if a higher-capacity platform is required.

Questions about this item

How loud does the R640 get when both 750 W power supplies and the dual Xeon 4110 CPUs run at full load 24/7?

The server uses redundant 750 W platinum-efficiency power supplies and dual 8-core Xeon Silver 4110 processors; fan speed scales with thermal load, so sustained full utilisation will raise acoustic output above idle levels.

Which drive trays and backplane connectors are already fitted so I know what drives to buy?

Eight 2.5-inch SAS/SATA hot-swap trays are installed and the PERC H730P controller supports both SAS and SATA drives in RAID 0, 1, 5, 6, 10, 50 or 60.

Will the X520/I350 daughter card connect to my existing 1 GbE copper switches and 10 Gb SFP+ uplinks?

The network daughter card includes two 1 GbE ports and two 10 Gb SFP+ ports, providing direct compatibility with both copper and fibre uplinks.
