Dense Scale-Out Platform

The Dell PowerEdge R640 is a dual-socket 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores and a 3.2 GHz turbo frequency. The system includes 256 GB of DDR4 2400 MHz registered ECC memory across eight 32 GB modules. Eight 1.2 TB 10K SAS drives and a PERC H730P controller provide the storage foundation.

Build Integration Requirements

The 1U chassis occupies a single rack unit and includes ready rails and a front bezel for standard cabinet mounting. Two hot-swap 750 W platinum power supplies deliver redundant power without consuming extra rack space. The Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports for flexible network connectivity. iDRAC 9 Enterprise enables remote management independent of the host operating system.

Sustained Load Behaviour

Redundant power supplies and hot-swap drive bays allow component replacement without service interruption during continuous operation. The PERC H730P controller supports RAID levels 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache backed by battery to protect in-flight data. Registered ECC memory corrects single-bit errors on the fly to maintain data integrity under heavy workloads. The platform supports up to 3 TB of DDR4 across 24 slots for future capacity expansion.

Questions about this item

How much memory can the R640 take before the 24 DDR4 slots are full?

The system supports up to 3TB of DDR4 across its 24 slots, so 256GB installed leaves room for more.

What thermal load should I plan for with two 750W platinum supplies running continuously?

Dual 750W platinum units share the load; each can draw up to its rated output under sustained work.

Which rack hardware must I have on site before the server arrives?

The box includes ready rails and a front bezel for a standard 1U rack opening.
