Dell M640 Blade Server

This Dell PowerEdge M640 blade server delivers dual Intel Xeon Gold 6128 processors running at 3.4 GHz with six cores each. It comes with 48 GB of DDR4 ECC registered memory and two 4 TB SATA 2.5-inch hard drives managed by a PERC H330 RAID controller. The system includes a 10 GbE dual-port 562T network adapter and iDRAC9 Enterprise remote management. It is a new unit with firmware fully updated to the latest stable version.

Ideal for dense compute clusters

The M640 suits environments that need high processor density in a half-height blade form factor with integrated 10 GbE networking and hardware RAID. Buyers who need more than two internal drive bays or require GPU acceleration should evaluate other platforms. The half-height design limits expansion to the onboard controller and the two 2.5-inch bays. Memory can scale to 1 TB if workloads grow beyond the installed 48 GB.

Two-drive SATA limit

The server supports a maximum of two 2.5-inch SATA drives connected to the PERC H330 controller, so storage capacity and I/O performance are capped by that physical constraint.

Questions about this item

Should I choose the 48 GB DDR4 configuration or add more memory up to the 1 TB maximum?

The system ships with 48 GB of DDR4 ECC registered memory installed and supports up to 1 TB total; add modules if your workloads need more capacity.

What does the 3.4 GHz Xeon Gold 6128 clock speed mean for actual performance?

Each of the two 6128 processors runs at 3.4 GHz with six cores and 19.25 MB cache, giving 12 cores total for parallel workloads.

How does the PERC H330 controller and SATA interface affect drive speed?

The PERC H330 SAS controller manages the two 4 TB SATA 2.5-inch drives; SATA links run at 6 Gb/s, so sustained throughput follows mechanical hard-drive limits.
