Dense 1U compute platform

The Dell PowerEdge R640 is a dual-socket rack server built for scale-out workloads that demand high core counts in minimal rack space. Two Intel Xeon Silver 4116 processors deliver 24 cores at 2.1 GHz with 3.0 GHz turbo, while 768 GB of DDR4 registered ECC memory fills all 24 DIMM slots. The platform suits virtualization clusters, database nodes and HPC front-ends that need maximum density per rack unit.

Enterprise storage and networking foundation

Eight 2.5-inch 2.4 TB 10K SAS drives connect through a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60 with battery-backed cache. Hot-swap bays and redundant 750 W platinum power supplies allow drive or PSU replacement without downtime. A quad-port daughter card adds two 1 GbE and two 10 Gb SFP+ links, and iDRAC 9 Enterprise provides full out-of-band management. Rails and bezel are included for immediate rack integration.

Memory capacity fixed at 768 GB

All 24 DDR4 slots are occupied by 32 GB modules, so the system arrives at its installed maximum of 768 GB with no free slots for expansion. Buyers who need more memory must replace existing modules rather than add to them. The board supports up to 3 TB total, but reaching that ceiling requires a complete memory swap.

Questions about this item

What does the 12 Gb/s SAS controller cap in practice?

The PERC H730P 2 GB controller runs at 12 Gb/s SAS and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through mode.

What physical space and rails does this 1U server need to mount?

It occupies 1U of rack height and ships with Ready Rails for standard 4-post rack installation.

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

Two Xeon Silver 4116 processors go into LGA 3647 sockets; 768 GB DDR4 fills 24 slots as 24×32 GB registered ECC modules.
