Dual-socket 1U rack server

This Dell PowerEdge R640 is a 1U rack server with two Intel Xeon Gold 6148 processors running at 2.40 GHz, each providing 20 cores for a total of 40 cores. It includes 768 GB of DDR4 2666 MHz registered ECC memory across 24 DIMM slots and eight 300 GB 10K SAS hard drives. The PERC H730P controller with 2 GB cache supports RAID 0, 1, 5, 6, 10, 50 and 60. Dual 750 W platinum power supplies and iDRAC 9 Enterprise are fitted.

Suited to dense scale-out workloads

The configuration suits dense scale-out data centre tasks that benefit from high core counts and large memory capacity in a 1U form factor. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections. Buyers who need more than 24 DIMM slots or a higher drive count should look elsewhere. The maximum supported memory is 3 TB and the chassis holds eight 2.5-inch drives.

PERC H730P RAID controller decides fit

The single specification that decides whether this is the right part is the Dell PERC H730P 2 GB 12 Gb/s SAS/SATA storage controller. It manages the eight installed 300 GB SAS drives and defines the available RAID levels. If the workload requires a different controller feature set or drive interface, this server will not match the requirement.

Questions about this item

How many CPU cores are available for sustained workloads?

The server has two Intel Xeon Gold 6148 processors, each with 20 cores, giving 40 cores total for sustained workloads.

What is the power supply rating and redundancy for continuous operation?

Two redundant 750 Watt Platinum efficiency power supplies are installed for continuous operation.

Which drive interface must the existing backplane support for the installed drives?

The eight installed 300 GB drives use a 12 Gb/s SAS interface, so the backplane must support SAS.
