Dual-socket 1U server

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 6148 processors. Each CPU delivers 20 cores at 2.40 GHz with a 3.7 GHz turbo frequency, giving 40 cores total. The system ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules at 2666 MHz. A PERC H730P controller with 2 GB cache manages eight 600 GB 10K SAS drives in 2.5 inch bays. Redundant 750 W platinum power supplies, iDRAC9 Enterprise, quad-port networking and rails complete the package.

Scale-out compute vs. specialised needs

This configuration suits dense scale-out workloads such as virtualization clusters, database nodes or high-performance computing where dual-socket density and SAS reliability are priorities. The 1U form factor and redundant power support continuous operation in standard racks. Buyers who require solid-state media, larger drive counts or GPU acceleration should evaluate alternative platforms, as the eight 2.5 inch bays and storage controller are designed for spinning SAS media and the chassis does not accommodate add-in accelerators.

PERC H730P RAID controller

The storage subsystem centres on the Dell PERC H730P 2 GB 12 Gb/s SAS/SATA controller with battery-backed cache. It supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode, directly determining which drive configurations and data-protection schemes are possible. The eight installed 600 GB 10K SAS drives connect through this controller, so any expansion or replacement must match the SAS interface and the RAID levels the H730P provides.

Questions about this item

Does this 1U rack server include the sliding rails needed to mount it in a standard cabinet?

Yes, the supplier title confirms that ready rails are included with the R640.

Can I keep the eight 600 GB 10K SAS drives installed and add larger SAS or SATA drives in the remaining bays later?

The PERC H730P controller supports both SAS and SATA drives, so you can mix the existing 600 GB disks with larger SAS or SATA units in the eight 2.5-inch bays.

How can I verify the dual Xeon Gold 6148 processors and 128 GB of DDR4 2666 MHz memory are recognised after the first boot?

Open the iDRAC 9 Enterprise interface or enter the system BIOS; both will show two 20-core CPUs at 2.4 GHz and 128 GB of registered ECC DDR4 running at 2666 MHz.
