Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. Two Intel Xeon Gold 6134 processors run at 3.2 GHz with eight cores each, supported by 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. The system fits eight 2.5-inch drive bays in a single rack unit.

Suits virtualization clusters; not for GPU workloads

This configuration suits virtualization clusters, hyper-converged infrastructure and database nodes that need high core count and large memory in minimal rack space. The PERC H730P controller with 2 GB cache handles RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need GPU acceleration or more than eight internal drives should look at a different platform.

512 GB DDR4 decides fit

The installed 512 GB of DDR4 registered ECC memory across 24 slots determines whether this server matches the workload. Memory can scale to 3 TB using the remaining slots. If the application requires more memory than 3 TB or a different memory type, this system will not meet the requirement.

Questions about this item

What does the 3.2 GHz base clock mean once the Xeon Gold 6134 is installed in this server?

The two Xeon Gold 6134 processors run at 3.2 GHz base frequency with a 3.7 GHz turbo boost, giving 16 total cores for dense compute workloads in a 1U chassis.

What storage throughput does the PERC H730P controller cap at in this configuration?

The H730P is a 12 Gb/s SAS/SATA controller with 2 GB cache and battery backup, supporting RAID 0/1/5/6/10/50/60 and pass-through for the eight installed SATA SSDs.

What physical space and mounting hardware does the R640 need to fit in a rack?

The server is a 1U rack unit and includes Ready Rails sliding rails plus a front bezel for standard four-post rack installation.
