DELL PowerEdge R640 1U Rack Server 2x Xeon Silver 4116 2.1GHz 12-Core 256GB DDR4

SKU CH-GRW7-WWDNB

Dual-socket 1U rack server with two 12-core Xeon Silver 4116 CPUs at 2.1 GHz, 256 GB DDR4 ECC, PERC H730P RAID controller, dual 300 GB 10K SAS drives, quad-port 1/10 GbE networking.

Dual-Socket 1U Platform

The Dell PowerEdge R640 is a dual-socket rack server built for dense scale-out data center computing. Two Intel Xeon Silver 4116 processors deliver 24 cores at 2.1 GHz with 3.0 GHz turbo. 256 GB of DDR4 registered ECC memory occupies eight of twenty-four slots. The 1U chassis includes redundant 750 W platinum power supplies, rails and a front bezel.

Upgrade From Single-Socket Or Older 2U

This system replaces single-socket servers or previous-generation 2U platforms when workloads demand more cores and memory channels in the same rack footprint. The jump is worth it for virtualisation clusters, database nodes or HPC tasks that scale across two sockets and can use the twelve 12 Gb/s SAS bays. Buyers who need GPU acceleration or more than two processors should look elsewhere.

Limits Of 12 Gb/s SAS And 1U Density

The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 over twelve 12 Gb/s SAS lanes, but the backplane only accepts 2.5-inch SAS or SATA drives. Four 1 GbE and two 10 Gb SFP+ ports handle network traffic, yet the 1U height leaves no room for full-height add-in cards. Memory tops out at 3 TB when all twenty-four slots are populated.

Questions about this item

What rack-mount hardware is supplied with this 1U server?

The package includes Dell Ready Rails and a front bezel for mounting the 1U chassis in a standard rack cabinet.

How are the two Xeon Silver 4116 processors and the 256 GB DDR4 memory installed from the factory?

Both 12-core CPUs are already seated in the two LGA 3647 sockets, and the 256 GB is populated as eight 32 GB DDR4 2400 MHz registered ECC DIMMs across the 24 available slots.

Which components in this configuration are hot-swappable for later replacement?

The two 300 GB 10K SAS drives, the dual 750 W power supplies and the PERC H730P controller battery can all be replaced while the server remains powered on.
