PowerEdge M640 Blade Server

The Dell PowerEdge M640 is a two-socket blade server built for dense compute environments. It ships with dual Xeon Gold 5220S processors at 2.7 GHz and 192 GB of DDR4 memory, making it suited for virtualisation clusters and database workloads that need high core counts in a shared chassis.

Suited for memory-heavy workloads.

This configuration fits teams running memory-intensive applications such as in-memory databases or large VM farms where the 18 cores per processor and 192 GB DDR4 provide headroom. Buyers who need dedicated GPU acceleration or more than two 2.5-inch drive bays should look at a different platform.

Dual Xeon Gold 5220S with 18 cores each

The pair of 5220S CPUs delivers 36 total cores at 2.7 GHz with 24.75 MB cache per chip, and that core count is the specification that determines whether the server matches your threading requirements. The PERC H330 controller manages the two 1.8 TB SAS drives, while iDRAC9 Enterprise handles remote management.

Questions about this item

Should I pick the dual 5220S Gold CPUs with 192GB DDR4 or a different CPU and memory mix?

The 2.7 GHz 18-core Gold 5220S pair and 192GB DDR4 ECC registered memory are factory-installed; the board supports up to 1TB total if you need more capacity later.

What does the 2.7 GHz 18-core figure deliver inside a live blade?

Each 5220S runs at 2.7 GHz with 18 cores and 24.75MB cache, giving 36 threads total for virtualisation, database or HPC workloads.

How does the SAS link and PERC H330 controller limit the two 1.8TB drives?

The PERC H330 manages the 2.5-inch SAS drives in RAID 0, 1 or JBOD; the 10GbE 562T adapter handles network traffic.
