Dual-socket 1U server for dense compute

This system delivers two 12-core Xeon Gold 5118 processors at 2.3 GHz with 256 GB DDR4 ECC memory in a single rack unit. Redundant 750 W platinum power supplies and a PERC H730P RAID controller with battery back-up support continuous operation. Integrated X520/I350 networking provides two 1 GbE and two 10 Gb SFP+ ports for flexible connectivity.

Suited to scale-out and virtualisation.

Buyers building Kubernetes clusters, hyper-converged nodes or database tiers gain high core density and ample memory slots. The 1U chassis lacks space for full-length accelerator cards, so GPU-dependent rendering or AI training should look elsewhere. Eight 2.5-inch drive bays limit raw capacity compared with larger form factors.

PERC H730P RAID controller with 2 GB cache

The onboard controller manages the eight 300 GB 10 K SAS drives and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Battery-backed write cache protects data during power loss. Storage expansion beyond the internal bays requires external enclosures or a different controller.

Questions about this item

Will this R640 fit in my existing 1U rack space and mount with the included hardware?

The server is a 1U rack unit and ships with ready rails and a front bezel for mounting in a standard rack.

Can I keep using my current SAS drives with the PERC H730P controller in this server?

The H730P 2GB controller supports SAS and SATA drives with RAID 0, 1, 5, 6, 10, 50, 60 and pass-through, so existing SAS drives will work.

How do I confirm the 256GB DDR4 memory and both Xeon Gold 5118 processors are detected after installation?

Check the iDRAC9 Enterprise interface or the system BIOS; both will show 256GB of DDR4 2400MHz memory and two 12-core CPUs at 2.3GHz with 3.2GHz turbo.
