Configured as a 1U rack server, this Dell PowerEdge R640 combines two Intel Xeon Gold 6238R processors (28 cores each, 2.20GHz base clock) with 512GB of DDR4 memory. The drive complement is eight 2.4TB 10K SAS hard drives, 19.2TB before RAID, filling every bay of the 8-bay 2.5-inch chassis.
The build is rounded out by PERC H740P hardware RAID (8GB cache), dual-port 10GbE RJ45 networking (Intel X550) and dual 750W power supplies. You also get an iDRAC9 Enterprise licence for out-of-band management and a rack rail kit.
With 19.2TB of raw capacity, it makes a natural backup repository, archive tier or departmental file server, and 56 cores and 512GB are ample for the storage services that run on it. With eight drives, RAID 6 keeps six drives' worth of capacity and survives two simultaneous drive failures.
Against an all-flash R640 build, this configuration favours capacity over latency. That is twice the memory of a lighter R640 build, which matters most for virtual machines and caching.
As a certified refurbished server, it is inspected, bench-tested and data-wiped by our Johannesburg team before release.

Frequently asked questions
How much raw storage does this PowerEdge R640 have?
- 8 × 2.4TB 10K SAS HDD, 19.2TB of raw capacity in total. Usable space depends on the RAID level you configure.
Is there room to add more drives?
- Every bay of the 8-bay 2.5-inch chassis is populated in this configuration, so adding capacity means larger drives rather than more of them.
How many processor cores does it have?
- Two Intel Xeon Gold 6238R processors with 28 cores each at a 2.20GHz base clock: 56 physical cores in total, backed by 512GB of memory.
Does it include remote management?
- Yes. The configuration lists an iDRAC9 Enterprise licence, which provides out-of-band management (power control and hardware monitoring) independent of the operating system.
