DELL PowerEdge R640 1U rack server 2x Xeon Silver 4116 2.1GHz 12-core 64GB DDR4 8x 400GB SSD H730P

Dual-socket 1U server for dense compute

The Dell PowerEdge R640 packs two Intel Xeon Silver 4116 processors, each with 12 cores at 2.1 GHz and 3.0 GHz turbo, into a single rack unit. Sixty-four gigabytes of DDR4 registered ECC memory and eight 400 GB SATA SSDs sit behind a PERC H730P hardware RAID controller. Quad-port networking with two 1 GbE and two 10 Gb SFP+ links plus iDRAC9 Enterprise remote management complete the package.

Replaces older 1U or 2U dual-socket boxes

If you are consolidating workloads from larger chassis or previous-generation 1U servers, the R640 delivers the same dual-socket capacity in half the rack space. The jump is worth it when you need 12 cores per CPU, hardware RAID 0/1/5/6/10/50/60 with battery-backed cache, and 10 Gb SFP+ connectivity without adding mezzanine cards. Redundant 750 W platinum power supplies also remove a common single point of failure.

Check rack depth, rail kit and memory expansion

Verify that your cabinet accommodates the 1U form factor with the included ready rails and front bezel. Confirm the DDR4 registered ECC modules match your existing memory population rules across the 24 DIMM slots if you plan to grow beyond the installed 64 GB toward the 3 TB maximum. Ensure SATA SSD caddies fit your hot-swap backplane and that SFP+ transceivers are available for the 10 Gb ports.
