Dense compute blade for virtualization clusters

The Dell PowerEdge M640 is a half-height blade server built for high-density virtualization and private-cloud workloads. Dual Intel Xeon Gold 6154 processors provide 36 cores at 3.0 GHz with 3.7 GHz turbo. 512 GB of DDR4 2666 MHz registered ECC memory fills 16 slots. Two 1.92 TB SATA SSDs connect through a PERC S140 controller supporting RAID 0, 1, 5 and 10.

Blade form factor limits expansion

The half-height blade format fits only Dell PowerEdge MX or M1000e enclosures and provides two 2.5-inch drive bays. No front bezel or ready rails are included. The integrated Matrox G200 GPU offers 8 MB video memory for basic console output only. A Broadcom 57810S-K dual-port 10 Gb daughter card handles network connectivity. iDRAC9 Enterprise enables remote management without an operating system installed.

Dual-socket LGA 3647 caps at two processors

The system ships with the maximum of two Xeon Gold 6154 CPUs installed, so no further processor upgrades are possible. Memory can grow from 512 GB to the platform limit of 1.5 TB using the 16 DDR4 slots. Storage is restricted to the two internal SATA or SAS bays unless the chassis provides shared storage. Buyers needing more than two sockets or additional local drive bays must choose a rackmount platform instead.

Questions about this item

Should I pick the 512 GB DDR4 configuration or add more memory later?

The server ships with 512 GB across 16 slots of DDR4 2666 MHz registered ECC. The platform supports up to 1.5 TB total, so you can expand later by filling the remaining slots with compatible DDR4 modules.

What does the 3.7 GHz turbo frequency actually deliver in a live workload?

Each of the two Xeon Gold 6154 processors has 18 cores running at 3.0 GHz base and can boost to 3.7 GHz on active cores. In multi-threaded workloads the all-core turbo will be lower, but bursty single-thread tasks can reach the higher clock for short periods.

How fast is the storage interface with the PERC S140 controller and the installed 1.92 TB SSDs?

The PERC S140 provides SATA 6 Gb/s connectivity to the two 1.92 TB SSDs. In RAID 0 the pair can deliver near 1 GB/s sequential throughput; RAID 1 mirrors for redundancy while keeping the same read speed.
