Dense 1U compute node

The Dell PowerEdge R640 is a dual-socket 1U rack server built for scale-out workloads. Two Intel Xeon Gold 5118 processors at 2.3 GHz with 12 cores each provide 24 threads of processing capacity. 512 GB of DDR4 ECC memory fills 16 of 24 slots and runs at 2400 MHz. Eight 800 GB SATA SSDs connect through a PERC H730P RAID controller with 2 GB cache.

Suited for virtualization clusters.

This configuration fits virtualization hosts, container platforms and database clusters that benefit from high core counts and redundant 750 W power supplies in a single rack unit. Quad-port networking with two 1 GbE and two 10 Gb SFP+ links supports distributed storage traffic. Buyers who require GPU acceleration, more than two processors or storage interfaces beyond SATA and SAS should look at other platforms because this chassis does not support those configurations.

PERC H730P RAID controller decides storage topology

The installed PERC H730P with 2 GB battery-backed cache manages all eight drive bays and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. This single controller determines which RAID levels are available, whether write-back caching is protected and how many logical volumes can be presented to the operating system.

Preguntas sobre este artículo

What maintenance will the PERC H730P controller's battery need?

The PERC H730P includes a battery-backed cache module that typically requires replacement every few years to maintain write-back caching protection during power loss.

Which limit appears first when both Xeon Gold 5118 CPUs run at 3.2 GHz turbo continuously?

The 750 W redundant power supplies and 1U thermal envelope will throttle the 12-core processors before the DDR4 memory or SATA SSD bandwidth becomes saturated.

How loud and hot does the server get with both 750 W PSUs loaded all day?

Dual platinum-efficiency supplies and high-speed 1U fans keep component temperatures within spec, but sustained load produces noticeable airflow noise typical for dense rack servers.
