4LFF Rack Server for Dense Storage
The Dell PowerEdge R640 in a 4-bay 3.5-inch chassis delivers a 1U rack footprint with room for four large-form-factor drives. One Intel Xeon Gold 6226 processor runs at 2.7GHz with twelve cores and 19.25 MB cache. 128GB of DDR4 ECC registered memory is installed, and the PERC H740P RAID controller manages SATA storage. Dual 750W supplies and iDRAC9 Enterprise remote management complete the platform.
Suits Storage-Heavy Workloads, Not GPU Compute
This configuration targets buyers who need high drive density in a single rack unit — virtualisation hosts, backup targets, or database nodes that benefit from 3.5-inch SATA capacity. The integrated graphics and lack of installed GPUs make it unsuitable for workloads requiring dedicated accelerator cards. Organisations needing more than one processor should note the second socket is empty but supported.
Single-Processor Xeon Gold 6226 Decides Fit
The installed Xeon Gold 6226 provides twelve cores at 2.7GHz; the second CPU socket remains vacant for future expansion. If the core count or clock speed does not match the licensing or performance profile of the intended application, the platform will not meet requirements. Memory scales to 7.68TB DDR4 across the full system, but the starting 128GB and single processor define the baseline capability.

Questions about this item
How much power do the dual 750W supplies draw when the R640 runs a 2.7GHz Xeon Gold 6226 at full load all day?
The system ships with two 750W power supplies; actual draw depends on the drives and add-in cards you install, so plan for the full 750W capacity per supply.
What drive caddies and SATA cables must I already own to populate the four 3.5-inch bays?
The 4LFF chassis accepts standard Dell 3.5-inch hot-plug caddies; SATA data and power cables are pre-routed to the PERC H740P backplane, so only the caddies are required.
Will my existing DDR4 ECC RDIMMs work alongside the installed 128GB in the remaining slots?
Yes, the R640 supports DDR4 ECC Registered memory up to 7.68TB; match speed and rank population rules when adding modules to the open DIMM slots.
