Blade density and dual-socket compute

The PowerEdge M640 is a half-height blade server that fits into PowerEdge MX and M1000e chassis. It ships with two Intel Xeon Gold 6230 processors, each running at 2.10 GHz with a 3.9 GHz turbo and twenty cores. The system includes 32 GB of DDR4 registered ECC memory across four modules and uses the LGA 3647 socket.

Storage controller and networking daughter card

A PERC H330 controller provides 12 Gb/s SAS and SATA connectivity with support for RAID 0, 1, 5, 10 and 50. Two 2.5-inch drive caddies are included for local storage. Networking is handled by a Broadcom 57810S-K dual-port 10 Gb blade network daughter card installed in the dedicated slot.

Management scope and expansion ceiling

iDRAC9 Enterprise enables full remote management including virtual console and lifecycle automation. The blade supports a maximum of two processors and 1.5 TB of DDR4 memory across sixteen slots. GPU capability is limited to the integrated Matrox G200 with 8 MB video memory, and no operating system is pre-installed.

Questions about this item

When will the installed 32GB DDR4 need to be expanded to reach the 1.5TB maximum?

The blade has 16 DDR4 slots and currently uses 4x 8GB modules; add registered ECC DDR4 2666MHz DIMMs to grow toward the 1.5TB limit.

What storage bottleneck appears first when the dual 10Gb ports and PERC H330 run sustained I/O?

The PERC H330 12Gb/s SAS/SATA controller and RAID 0/1/5/10/50 manage the 2.5" bays; sustained throughput is capped by the installed drives and the 10Gb network uplinks.

How loud and hot does the M640 get when both Xeon Gold 6230 CPUs run at 3.9GHz turbo all day?

As a half-height blade it relies on the M1000e or MX chassis fans; the dual 20-core CPUs at 3.9GHz turbo push the thermal load into the shared chassis cooling.
