Dense two-socket blade for virtualisation hosts

The PowerEdge M640 blade mounts two Xeon Gold 6248 processors at 2.5 GHz, giving 40 cores and 80 threads in a half-height form factor. It ships with 192 GB of DDR4 ECC registered memory and a PERC H330 SAS controller driving two 4 TB SATA drives. iDRAC9 Enterprise provides full out-of-band management.

Buyers needing more than two drive bays

This blade only supports two 2.5-inch drives and has no PCIe slots for add-in accelerators, so workloads that demand large local storage arrays or discrete graphics must look at full-height or rack-mount alternatives. The fixed maximum of two processors also limits vertical scaling.

PERC H330 controller with two 4 TB SATA drives

The installed PERC H330 RAID controller manages the pair of 4 TB SATA drives in whatever RAID level the operating system requires. Confirm the controller’s RAID feature set matches the redundancy or performance profile the deployment needs before ordering.

Questions about this item

What SATA interface speed limits the 2x 4TB 2.5" hard drives in this M640 blade?

The drives connect through the PERC H330 controller over SATA, so each drive runs at the SATA 6 Gb/s link speed the controller provides.

What physical space must the chassis provide for this M640 blade to seat correctly?

The blade measures 22 x 22 x 10 in and weighs 20, so the enclosure bay must accept those exact dimensions and weight.

How is the PERC H330 RAID controller set up during initial deployment, and what step is often missed?

After seating the blade, enter the controller BIOS on boot, create a virtual disk across the 2x 4TB drives, then initialise it before installing an OS.
