Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Gold 6134 processors, each running at 3.2 GHz with eight cores. The system ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots, leaving room to expand up to 3 TB. It is suited for organisations that need dense compute in a single rack unit.

Hot-swap drive bays and redundant power

Eight 2.5-inch SAS/SATA drive bays support hot-swap replacement, and the PERC H730P controller with 2 GB cache provides RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through. Two 750 W platinum-efficiency power supplies operate in redundant mode, and a quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections. iDRAC 9 Enterprise gives full remote management, while ready rails and a front bezel simplify rack installation.

Enterprise thermal design for continuous load

The 1U chassis uses redundant fans managed by the iDRAC firmware to maintain safe inlet temperatures under sustained dual-processor workloads. Platinum-rated power supplies reduce waste heat and lower overall power draw compared with lower-efficiency units. Acoustic output is typical for a rack-mount server intended for data-centre aisles rather than office spaces.

Questions about this item

What SAS speed does the PERC H730P controller support and how does that limit drive throughput?

The PERC H730P is a 12Gb/s SAS controller, so attached SAS drives are capped at 12Gb/s per lane.

What physical space and mounting hardware does this 1U server require?

The R640 occupies 1U of rack height and ships with Dell Ready Rails and a front bezel for installation.

How is the PERC H730P battery installed and what step is often missed?

The battery module plugs into the controller card; the step often missed is securing the battery cable clip so the battery stays seated during vibration.
