Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre workloads. It ships with two Intel Xeon Gold 5118 processors, each running at 2.3 GHz with 12 cores. The system includes 768 GB of DDR4 ECC memory across 24 slots and eight 300 GB 10K SAS drives managed by a PERC H730P controller. Redundant 750 W platinum power supplies and iDRAC9 Enterprise remote management complete the package.

Virtualisation and Database Workloads

This configuration suits virtualisation clusters, database nodes and high-performance computing tasks that benefit from 24 total cores and a large memory footprint. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Organisations requiring GPU compute, more than eight 2.5-inch drive bays or direct-attached storage beyond SAS and SATA should evaluate other platforms.

768 GB DDR4 Registered ECC Memory

The installed 768 GB of DDR4 2400 MHz registered ECC memory occupies all 24 DIMM slots and supports a maximum capacity of 3 TB. Buyers must verify that their workload fits within this memory ceiling or plan a configuration change before deployment.

Questions about this item

How much power do the two 750 Watt Platinum supplies draw when the R640 runs at full load all day?

Each supply is rated at 750 Watt Platinum efficiency; actual draw depends on workload but the redundant pair is sized for the dual 12-core Xeon Gold 5118 configuration.

Which cabling and rail kit items must I already have to install this 1U server in a standard rack?

Ready Rails and a front bezel are included; you only need to provide rack mounting screws and SAS or SATA cables if you add drives beyond the eight installed 300 GB SAS units.

Will the PERC H730P controller recognise older 6 Gb/s SAS drives I might keep from a previous array?

The H730P supports 12 Gb/s SAS and SATA with pass-through, so legacy 6 Gb/s SAS drives will operate at their native speed when connected to the eight 2.5-inch bays.
