Dual-Socket 1U Rack Server

The Dell PowerEdge R640 is a 1U rackmount server built for dense scale-out computing. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. The system includes 128 GB of DDR4 registered ECC memory across 8 modules. A PERC H730P storage controller with 2 GB cache manages the installed drives.

Fits dense virtualisation.

This server suits environments that need high compute density in a single rack unit, such as virtualisation clusters or cloud workloads. The chassis provides eight 2.5-inch drive bays, populated here with two 400 GB SATA SSDs. Buyers who require more than eight internal drive bays will need a different chassis. Workloads demanding GPU acceleration are not supported by this 1U form factor.

Eight 2.5-inch bays define storage capacity

The critical specification is the eight-bay 2.5-inch front chassis, which sets the maximum number of internal drives. The installed PERC H730P controller supports SAS and SATA drives with RAID levels 0, 1, 5, 6, 10, 50 and 60. Two 400 GB SATA SSDs are included, leaving six bays available for expansion. Network connectivity uses a quad-port daughter card with two 1 GbE and two 10 Gb SFP+ ports.

Questions about this item

Should I choose the 2.3 GHz 12-core or the 3.2 GHz turbo version?

Both refer to the same Xeon Gold 5118; the 2.3 GHz is the base clock and the 3.2 GHz is the maximum turbo frequency, so the installed processors already provide both speeds.

What does 128 GB DDR4 2400 MHz deliver in this R640?

Eight 16 GB registered ECC modules running at 2400 MHz fill eight of the 24 slots, giving 128 GB of error-correcting memory with 16 slots still free for expansion up to 3 TB.

How does the PERC H730P 12 Gb/s SAS/SATA controller limit the two 400 GB SSDs?

The controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through at 12 Gb/s SAS and 6 Gb/s SATA; the installed 400 GB SATA SSDs will run at the SATA 6 Gb/s link speed.
