Dual-Socket 1U Rack Server

The Dell PowerEdge R640 is a 1U rackmount server designed for dense scale-out data centre computing. It ships with two Intel Xeon Silver 4116 processors, each running at 2.1 GHz with 12 cores and a 3.0 GHz turbo frequency. The system includes 256 GB of DDR4 2400 MHz registered ECC memory across eight 32 GB modules.

Suited for Virtualisation, Limited for GPU Workloads

This configuration suits organisations consolidating virtual machines or running memory-intensive applications within a single rack unit. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 for local storage redundancy. Buyers requiring GPU acceleration or more than two processor sockets will need a different platform.

24 DDR4 Slots Define Maximum Memory

The motherboard provides 24 DDR4 DIMM slots with a maximum supported capacity of 3 TB. The installed 256 GB occupies eight slots, leaving room for significant expansion using registered ECC modules. This slot count and memory ceiling are the key figures when planning future capacity upgrades.

Questions about this item

How much power do the dual 750 W platinum supplies draw when the R640 runs at full load all day?

Each supply is rated at 750 watts with platinum efficiency, and the server includes two for full redundancy.

Which drive trays and controller are included so I can add my own storage?

Eight 2.5-inch SAS/SATA trays and a PERC H730P 2 GB controller supporting RAID 0/1/5/6/10/50/60 are fitted.

Will the quad-port X520/I350 network card work with my existing 1 GbE and 10 Gb SFP+ switches?

The daughter card provides two 1 GbE and two 10 Gb SFP+ ports for direct connection to both switch types.
