Dual-socket Xeon Gold 5218R server

The Dell PowerEdge R640 delivers 40 cores at 2.1 GHz across two processors, backed by 32 GB of DDR4 ECC memory in a 1U rack chassis. It targets virtualisation hosts, database nodes and dense compute clusters that need high thread counts in minimal rack space.

PERC H740P RAID with 10 GbE networking

The PERC H740P controller manages up to four 3.5-inch SATA drives through a hardware RAID engine with dedicated cache. Dual 10 GbE ports on the 562T adapter sustain throughput for storage replication and east-west traffic without saturating the interconnect.

Replaces single-socket or older dual-socket boxes

Organisations consolidating multiple legacy servers onto one platform gain density and management simplicity through iDRAC9 Enterprise remote control. The jump is worth it when workloads exceed the memory or core ceiling of a single-socket design and require room for future DDR4 expansion to 7.68 TB.

Questions about this item

How loud and hot does the R640 get with dual Xeon Gold 5218R CPUs running continuously?

The chassis uses dual 750 W power supplies and integrated graphics; fan speed scales with CPU load through iDRAC9 thermal policies.

What drives and caddies do I need to populate the four 3.5-inch bays?

The PERC H740P controller supports SATA drives; drives are not installed, so you supply 3.5-inch SATA HDDs or SSDs and compatible caddies.

Can I keep my existing DDR4 ECC registered modules and add them to the 32 GB already installed?

The system has 32 GB of DDR4 ECC registered memory in two 16 GB modules; additional DDR4 ECC registered DIMMs can fill remaining slots up to 7.68 TB.
