Dense Compute Platform

The Dell PowerEdge R640 is a 1U rack server built for scale-out data centre workloads. It ships with two Intel Xeon Gold 6148 processors, each delivering 20 cores at 2.4 GHz with a 3.7 GHz turbo frequency. The system includes 64 GB of DDR4 registered ECC memory across four 16 GB modules and a PERC H730P controller with 2 GB cache. Eight 800 GB SATA SSDs populate the front 2.5-inch bays, while dual 750 W platinum power supplies and iDRAC9 Enterprise provide redundancy and remote management.

Virtualisation and Database Targets

This configuration suits organisations running virtualised environments, database clusters or high-performance computing tasks that benefit from 40 total cores and fast local storage. The quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who need more than 64 GB of memory or who require additional drive bays beyond the eight installed SSDs should evaluate larger chassis options.

Storage Controller Decides Fit

The PERC H730P 2 GB controller governs which RAID levels are available and how the eight SATA SSDs are presented to the operating system. It supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode, so the choice of controller directly determines data protection and performance characteristics. Verify that the supported RAID modes match your application requirements before deployment.

Questions about this item

What storage throughput does the H730P controller’s 12Gb/s SAS/SATA interface cap at in practice?

The PERC H730P supports 12Gb/s SAS and 6Gb/s SATA, so the eight installed 800GB SATA SSDs are limited to the 6Gb/s SATA link speed.

What rack hardware and clearances are needed to mount this 1U server?

Ready Rails are included for square-hole or round-hole 4-post racks; the chassis is 1U high and uses 2.5" drive bays, so allow front cable clearance and rear exhaust space.

How are the CPUs and memory installed, and what step is often missed?

Both Xeon Gold 6148 processors are pre-installed in the LGA 3647 sockets; the 64GB DDR4 2666MHz Registered ECC memory occupies four of 24 slots — verify the memory configuration matches the optimised population order in the service manual.
