Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Silver 4110 processors, each running at 2.1 GHz with eight cores. The system includes 128 GB of DDR4 2400 MHz registered ECC memory across eight 16 GB modules. Dual 750 W platinum hot-swap power supplies provide redundancy.

24 DIMM slots for DDR4 expansion

The motherboard provides 24 DDR4 slots and supports a maximum of 3 TB of registered ECC memory. This capacity ceiling is the single specification that determines whether the chassis can meet your workload’s memory footprint. Buyers who need more than 3 TB of system memory cannot use this platform.

Eight 2.5-inch drive trays and quad-port networking

The unit includes eight 2.5-inch SAS/SATA hot-swap trays without any drives installed, so storage must be sourced separately. The PERC H730P controller with 2 GB cache enables RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections, while iDRAC 9 Enterprise handles remote management. Ready rails and a front bezel are included for immediate rack mounting.

Questions about this item

What does the 2.1 GHz base clock on the Xeon Silver 4110 mean once the server is running real workloads?

The two 8-core processors run at 2.1 GHz base and can turbo to 3.0 GHz, giving 16 cores total for parallel tasks such as virtualization or database work.

How does the PERC H730P controller's 12 Gb/s SAS/SATA interface limit drive performance in practice?

The controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through at 12 Gb/s, so SSD throughput is capped by that link speed rather than the drive's own maximum.

What physical space and mounting hardware does the 1U chassis need to fit in a standard rack?

The server occupies 1U of rack height, includes ready rails for square-hole or round-hole cabinets, and ships with a front bezel for a clean finish.
