Dense 1U Dual-Socket Compute Platform

The Dell PowerEdge R640 is a 1U rack server built for scale-out data centre workloads. Two Xeon Gold 6148 processors deliver 40 cores at 2.4 GHz with a 3.7 GHz turbo frequency. Sixty-four gigabytes of DDR4 registered ECC memory and a PERC H730P controller with battery-backed cache support RAID 0, 1, 5, 6, 10, 50 and 60. Eight 300 GB 10K SAS drives and quad-port networking with two 1 GbE and two 10 Gb SFP+ connections complete the package.

Suits Virtualisation Hosts and Database Nodes

This configuration fits clusters that need high core density and fast local storage in a single rack unit. Redundant 750 W platinum power supplies and iDRAC 9 Enterprise simplify remote management at scale. Buyers who need more than 24 memory slots, additional drive bays, or GPU acceleration should evaluate larger chassis options.

300 GB 10K SAS Drives Define Storage Profile

The eight 2.5-inch 300 GB 10 000 rpm SAS drives determine usable capacity and I/O performance. RAID level choice on the H730P controller directly affects available space and redundancy. Ensure the total raw capacity meets application requirements before deployment.

Questions about this item

Which rack rails are included for mounting the 1U chassis?

Dell Ready Rails are supplied with the server for installation in a standard rack cabinet.

Can the PERC H730P controller use the existing 300 GB SAS drives in a RAID 10 array?

Yes, the H730P supports RAID 10 and the eight 300 GB 10K SAS drives are already installed.

How do I confirm the dual Xeon Gold 6148 CPUs and 64 GB DDR4 are recognised after power-on?

Check the iDRAC9 Enterprise interface or the BIOS POST screen; both will show two 20-core processors at 2.4 GHz and 64 GB of registered ECC memory.
