Here the Dell PowerEdge R840 2U rack server comes with four Intel Xeon Gold 6248 chips (2.50GHz, 20 cores each) alongside 256GB of DDR4 memory. Storage comes as eight 1.92TB SAS SSDs, 15.36TB raw, filling every bay of the 8-bay 2.5-inch chassis.
Supporting hardware includes PERC H740P hardware RAID (8GB cache), quad-port 10GbE RJ45 networking (Intel X550-T4) and dual 1600W power supplies. The configuration also lists an iDRAC9 Enterprise licence for out-of-band management and a rack rail kit.
This is the kind of build that suits database servers and virtualisation hosts where storage latency, not capacity, sets the pace. RAID 10 across the eight drives would keep four drives' worth of space while mirroring every write.
Compared with a hard-disk build of the same R840, this all-flash configuration trades raw capacity for much lower storage latency. That is twice the memory of a lighter R840 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 R840 have?
- 8 × 1.92TB SAS SSD, 15.36TB 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?
- Four Intel Xeon Gold 6248 processors with 20 cores each at a 2.50GHz base clock: 80 physical cores in total, backed by 256GB 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.
