DELL PowerEdge R640 1U 2x Xeon Silver 4110 2.1GHz 256GB DDR4 8x 1.2TB SAS H730P

Dense 1U Dual-Socket Platform

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 eight 32 GB modules and a PERC H730P controller with 2 GB cache. Eight 1.2 TB 10K SAS drives and a quad-port 1GbE/10GbE SFP+ network daughter card are installed. iDRAC9 Enterprise and redundant 750 W platinum power supplies complete the package.

Suits Scale-Out Compute.

This configuration targets dense scale-out workloads such as virtualisation clusters, web tiers or HPC front-ends that benefit from dual-socket performance in a single rack unit. The eight 2.5-inch bays are fully populated with SAS hard drives, so buyers who need flash-accelerated storage tiers or more than eight drive slots should consider other chassis. The board offers 24 DIMM slots with a 3 TB ceiling, yet GPU-enabled workloads cannot be supported because the 1U form factor lacks PCIe expansion space for accelerator cards.

24 DDR4 Slots Decide Memory Growth

The server provides 24 DDR4 memory slots with a maximum capacity of 3 TB, so the 256 GB installed today can be expanded significantly without replacing the platform. All slots accept registered ECC DDR4 modules, and the Silver 4110 CPUs support six memory channels each. Buyers planning large in-memory databases or virtualisation hosts should verify their target capacity against the 3 TB limit before ordering.
