DELL PowerEdge R640 1U rack server 2x Xeon Silver 4110 2.1GHz 8-core 256GB DDR4 H730P 2x 400GB SSD

1U dual-socket rack server

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Silver 4110 processors running at 2.1 GHz with eight cores each. It ships with 256 GB of DDR4 registered ECC memory across 24 slots and a PERC H730P 2 GB controller managing two 400 GB SATA SSDs. Dual 750 W redundant power supplies, an X520/I350 quad-port network card and iDRAC9 Enterprise complete the package. Rails and bezel are included.

Suits dense scale-out workloads

This configuration fits environments that need high compute density in a single rack unit with hardware RAID and remote management built in. Buyers who require more than eight 2.5-inch drive bays or additional PCIe expansion beyond the integrated networking should evaluate larger chassis options. The fixed 1U height also limits GPU or FPGA accelerator installation.

24 DDR4 slots up to 3 TB

The motherboard provides 24 DIMM slots supporting DDR4 registered ECC modules with a maximum capacity of 3 TB. This ceiling determines whether the server can grow into memory-intensive database or virtualisation roles without a platform change.
