Dense 1U dual-socket server

This Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Gold 5118 processors, each running at 2.30 GHz with 12 cores. It ships with 512 GB of DDR4 registered ECC memory across 16 modules and includes a PERC H730P controller with 2 GB cache. Eight 1.2 TB 10K SAS drives and dual 750 W platinum power supplies complete the package.

Suited for memory-heavy scale-out workloads

The system targets dense virtualization, database and high-performance computing clusters that benefit from 24 total cores and a large DDR4 footprint. The 24 DIMM slots and 3 TB maximum capacity leave room for growth. Buyers who need more than two processors, GPU-ready expansion or storage interfaces beyond SAS and SATA should evaluate other platforms.

512 GB DDR4 registered ECC memory installed

The 512 GB DDR4 2400 MHz configuration fills 16 of the 24 available slots with 32 GB modules. This is the single specification that determines whether the server meets immediate capacity requirements or requires additional memory investment before deployment.

Vragen over dit artikel

What rack height and rail kit does the PowerEdge R640 require for mounting?

The server is a 1U rack unit and ships with Ready Rails for standard four-post rack installation.

How are the two Xeon Gold 5118 processors and the 512GB DDR4 memory installed, and what step is often missed?

Both LGA 3647 sockets are already populated with the 12-core 2.30 GHz CPUs; the 16 registered ECC DIMMs fill 16 of the 24 DDR4 slots, so the commonly missed step is verifying the memory population order in the service manual before adding more modules.

Which components in the R640 are hot-swappable and will need replacement over time?

The eight 1.2TB 10K SAS drives, the two 750 Watt platinum power supplies, and the PERC H730P controller battery are all hot-swappable and are the primary parts that will require replacement during the server's service life.
