DELL PowerEdge M640 Blade Server 2x Xeon Gold 5220S 256GB DDR4 2x 1.8TB SAS

Blade Server with Dual Xeon Gold 5220S

The Dell PowerEdge M640 is a half-height blade server built for dense compute clusters. Two Intel Xeon Gold 5220S processors run at 2.7 GHz with 18 cores each, delivering 36 cores total. The system ships with 256 GB of DDR4 ECC registered memory and a PERC H330 SAS RAID controller. Integrated iDRAC9 Enterprise enables remote management across the chassis.

Suited for virtualisation hosts needing high core

This blade fits organisations that run many virtual machines or containers on shared storage and want a compact, remotely manageable node. Buyers who require more than two internal drives or direct GPU acceleration should look at other configurations. The fixed two-drive bay limit and integrated graphics restrict local capacity and GPU workloads.

Maximum memory capacity of 1 TB DDR4

The M640 supports up to 1 TB of DDR4 across its DIMM slots, so the installed 256 GB can be expanded significantly. This ceiling decides whether the blade can grow with your workload or if a larger memory footprint is needed from the start. All additional modules must be DDR4 ECC registered to match the installed specification.
