Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rackmount server system built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores and a 3.7 GHz turbo frequency. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots and a PERC H730P 2 GB storage controller with battery-backed cache.

Suits virtualization and database workloads.

This configuration suits virtualization clusters, database servers and high-density compute farms that need dual-socket performance in a single rack unit. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who need GPU acceleration or more than eight 2.5-inch drive bays should look at alternative platforms.

Eight 2.5-inch drive bays with PERC H730P RAID

The chassis supports eight 2.5-inch SATA or SAS drives and currently holds two 400 GB enterprise SATA SSDs. The H730P controller enables RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Maximum memory capacity reaches 3 TB across 24 slots when fully populated. iDRAC 9 Enterprise and redundant 750 W platinum power supplies complete the package.

Questions about this item

Does the server ship with rails and a bezel, or must I order them separately?

Ready Rails and a front bezel are included in the box, so no separate purchase is required.

Should I choose the 2 x 400 GB SATA SSDs or add larger drives for capacity?

The two 400 GB SATA SSDs are installed; the 8-bay 2.5" chassis has six empty bays for additional SATA or SAS drives.

What does the 2.4 GHz base clock with 3.7 GHz turbo mean for sustained workloads?

Each Xeon Gold 6148 runs at 2.4 GHz base and can boost to 3.7 GHz under load, giving 20 cores per processor for parallel tasks.
