Dense compute in a 1U rack node

The Dell PowerEdge R640 packs two Xeon Silver 4114 processors and 384 GB of DDR4 ECC memory into a single rack unit, giving virtualisation hosts or database clusters a high core count without consuming extra height. Ten cores per CPU at 2.2 GHz provide steady throughput for multi-tenant workloads, while the PERC H740P controller manages up to four 3.5-inch SATA bays for local storage arrays.

Replaces older dual-socket 1U boxes

Sites running earlier Xeon E5 or first-generation Scalable platforms gain a direct upgrade path: double the installed memory ceiling to 7.68 TB and a newer iDRAC9 Enterprise licence for remote lifecycle control. The jump is worth it when consolidation ratios are limited by DIMM slots rather than CPU threads, or when firmware-update automation becomes a daily operational cost.

Sustained load behaviour

Dual 750 W supplies and the 10 GbE 562T adapter keep throughput stable during extended backup windows or replication streams, and the 4 LFF bay layout allows spindle-heavy datasets to stay local without throttling. Integrated graphics and the iDRAC9 dedicated port mean console access remains responsive even when all CPU cores are saturated by compute jobs.

Vragen over dit artikel

How deep is the rack space required for the 36 x 24 x 10 inch chassis?

The chassis measures 36 inches deep, so the rack must provide at least that much usable depth plus cable clearance at the rear.

Which screws secure the PERC H740P RAID controller during installation?

The PERC H740P controller mounts in the dedicated internal slot and is held by a single retention screw on the bracket.

When should the 750 W power supplies be replaced?

Replace a power supply if the iDRAC9 Enterprise console reports a fault LED or if the unit fails self-test during boot.
