Purpose-built 1U density

This Dell PowerEdge R640 is a 1U rack server designed for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. The system includes 768 GB of DDR4 registered ECC memory and eight 400 GB SATA SSDs managed by a PERC H730P controller with 2 GB cache.

Fit and alternatives

The configuration suits workloads that need high core counts and fast local storage in a single rack unit. Buyers who need more than 24 memory slots, more than eight 2.5-inch drive bays, or a different storage interface should look at other platforms. The server is not for environments that require GPU acceleration or larger form-factor expansion cards.

Deciding specification

The installed memory capacity of 768 GB across 24 populated DDR4 slots is the key figure for capacity planning. With all slots filled, further memory upgrades require replacing existing 32 GB modules. Verify that your application can operate within this limit before purchase.
