Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rack server built for dense data-centre deployments. It ships with two Intel Xeon Silver 4110 processors running at 2.1 GHz, each providing eight cores. The system includes 768 GB of DDR4 2400 MHz registered ECC memory across 24 slots. Redundant 750 W platinum power supplies and ready rails are included.

Virtualisation and database workloads

This configuration suits environments that need high core counts and large memory capacity in a single rack unit, such as virtualisation clusters or in-memory databases. The eight 300 GB 10 K SAS drives and H730P controller deliver hardware RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need solid-state storage, GPU compute or more than two processors should consider other platforms.

768 GB DDR4 registered ECC memory

The installed 768 GB of DDR4 registered ECC memory across 24 DIMM slots is the decisive specification for memory-bound applications. The board supports up to 3 TB maximum capacity, allowing future expansion. Workloads that exceed this ceiling or require a different memory generation will not be compatible with this system.

Questions about this item

What comes with the server and what must I add myself?

The unit ships with two Xeon Silver 4110 processors, 768 GB DDR4 ECC memory across 24 slots, eight 300 GB 10K SAS drives, a PERC H730P 2 GB controller, a quad-port X520/I350 network card, iDRAC9 Enterprise, two 750 W redundant power supplies, rails and a front bezel. No additional components are required for basic operation.

Should I choose a different drive count or capacity for this configuration?

This listing specifies eight 300 GB 10K SAS drives filling every 2.5-inch bay. If you need more capacity or solid-state drives, you would have to replace the installed drives or select a different listing.

What does the 768 GB memory figure mean when the server is running workloads?

The 768 GB is provided as 24 modules of 32 GB DDR4 2400 MHz registered ECC, occupying all memory slots. This gives the maximum installed capacity for this specific build and supports large virtualisation or database workloads without further memory upgrades.
