DELL PowerEdge M640 Blade 2x Xeon Gold 6240Y 256GB DDR4 2x 300GB SAS

Purpose-built blade server

The Dell PowerEdge M640 is a two-socket blade designed for dense compute clusters. Two Xeon Gold 6240Y CPUs provide eighteen cores each at 2.6 GHz with 24.75 MB cache. Installed memory totals 256 GB of DDR4 ECC registered DIMMs across the chassis. Storage consists of two 300 GB 10K SAS drives managed by a PERC H330 controller.

Fit for virtualisation hosts.

This configuration suits organisations running hypervisor farms or HPC nodes that rely on shared storage arrays. The 600 GB of local SAS capacity is modest, so workloads needing large resident datasets should look elsewhere. Remote management via iDRAC9 Enterprise and a dual-port 10 GbE adapter simplify fleet operations. Buyers requiring GPU acceleration or more than two drive bays need a different platform.

Dual 18-core Xeon Gold 6240Y processors

The pair of 2.6 GHz CPUs defines the blade’s compute ceiling and licensing baseline. Each socket delivers eighteen cores and 24.75 MB cache, fixing the maximum thread count and per-socket memory bandwidth. Memory scales to 1 TB using DDR4 modules, while the SAS interface and PERC H330 set the storage protocol. Confirm core-count licensing and memory growth plans against these fixed processor specifications before purchase.
