Dell PowerEdge M640 Blade Server

The Dell PowerEdge M640 is a half-height blade server built for dense compute environments. It ships with two Intel Xeon Gold 6252 processors running at 2.1 GHz, providing 48 cores total. Installed memory is 48 GB of DDR4 ECC registered RAM. Storage consists of two 1.8 TB SAS hard drives managed by a PERC H330 controller.

Who This Blade Suits And Who It Does Not

This blade suits data centres running virtualisation or high-throughput workloads that need many cores in a compact chassis. Remote management is handled by iDRAC9 Enterprise. Buyers needing more than two 2.5-inch drive bays or a different storage interface should look at other platforms.

Two Xeon Gold 6252 CPUs At 2.1 GHz

The pair of Xeon Gold 6252 processors delivers 24 cores each at a base frequency of 2.1 GHz with 35.75 MB cache per chip. This CPU configuration determines the server's peak multi-threaded performance and licensing costs. Verify that your workload and software licences align with this 48-core count before purchase.

Questions about this item

When will the two 1.8TB SAS drives or the PERC H330 RAID controller need replacement?

The SAS drives are mechanical and will eventually wear out; the PERC H330 controller has no moving parts and typically lasts the server's life.

What limit appears first when both Xeon Gold 6252 CPUs run at 2.1 GHz continuously?

The blade chassis power and cooling budget will throttle the 48 cores before the CPUs hit their own thermal ceiling.

How loud and hot does the M640 blade get during all-day operation?

Noise and heat depend on the enclosure fans; the blade itself has no integrated fans and relies on the chassis for airflow.
