Dell PowerEdge R640 4x3.5" Server

The Dell PowerEdge R640 is a 1U rack-mount server designed for virtualisation, database and general compute workloads. It arrives with a single Intel Xeon Gold 5120 processor running at 2.2 GHz with 14 cores and 128 GB of DDR4 ECC registered memory installed. The chassis supports up to four 3.5-inch SATA drive bays and a second processor socket for future expansion.

PERC H740P RAID Controller and iDRAC9 Enterprise

The Dell PERC H740P hardware RAID controller manages the SATA drives with cache-backed redundancy options. The iDRAC9 Enterprise licence provides full remote management including virtual console, power control and hardware health monitoring over a dedicated network port. Two 750 W power supplies are fitted for redundant operation.

128 GB DDR4 ECC Registered Memory Installed

The system ships with 128 GB of DDR4 ECC registered memory populated across the available DIMM slots. The platform supports a maximum memory capacity of 7.68 TB when both processor sockets are occupied and all slots are filled with supported modules. No drives are installed; storage must be added separately.

Questions about this item

How many additional memory modules can be added to reach the 7.68 TB maximum?

The system has 128 GB installed and supports up to 7.68 TB total DDR4 ECC registered memory across all slots.

Will the PERC H740P controller or the four 3.5" SATA drive bays become the throughput bottleneck first?

The PERC H740P handles 12 Gb/s per port while each SATA bay is limited to 6 Gb/s, so the drive interfaces saturate before the controller.

How much acoustic output and heat do the two 750 W power supplies produce under continuous load?

Dual 750 W supplies with redundant design share the load; the iDRAC9 Enterprise remote management monitors real-time temperature and fan speed for thermal control.
