Dual-socket blade for dense compute

This half-height PowerEdge M640 blade fits into MX or M1000e chassis and ships with two Intel Xeon Gold 6154 processors running at 3.0 GHz with 3.7 GHz turbo. Eighteen cores per CPU give 36 cores total, backed by 128 GB of DDR4-2666 registered ECC memory across eight slots. The PERC H330 controller manages two 1.92 TB SATA SSDs in a choice of RAID 0, 1, 5, 10 or 50. A Broadcom 57810S-K dual-port 10 Gb daughter card and iDRAC9 Enterprise provide networking and remote management out of the box.

Half-height blade limits expansion

The blade form factor restricts you to two 2.5-inch drive bays and a single mezzanine slot for the included 10 Gb card; no further PCIe cards can be added inside the blade itself. Memory tops out at 1.5 TB across 16 DDR4 slots, so the current 128 GB leaves room to grow but cannot exceed that ceiling. The H330 controller supports SATA and SAS but does not present NVMe to the operating system, and the Matrox G200 graphics core is limited to 8 MB video memory for basic console output only.

Verify chassis and cooling before ordering

This server requires a compatible PowerEdge MX or M1000e enclosure with available half-height slots and sufficient power and cooling budget for dual 18-core CPUs. Confirm the chassis firmware supports the M640 and that the 57810S-K mezzanine matches your fabric modules. No operating system, bezel or rails are included, so plan for OS licensing and physical mounting separately.

Questions about this item

Should I pick the 128 GB DDR4 configuration or add more memory up to the 2 TB maximum?

The server ships with 128 GB of DDR4 2666 MHz ECC across 8 of the 16 slots, leaving room to scale to 2 TB if your workloads need it.

What does the 3.0 GHz base clock with 3.7 GHz turbo mean for real workloads?

Each of the two 18-core Xeon Gold 6154 CPUs runs at 3.0 GHz and can boost to 3.7 GHz, giving 36 cores that accelerate bursty tasks while sustaining high throughput.

How does the PERC H330 controller and SATA 6 Gb/s interface limit the installed 1.92 TB SSDs?

The H330 supports SATA 6 Gb/s and SAS 12 Gb/s, so the 1.92 TB SATA SSDs operate at their full 6 Gb/s link speed with RAID 0, 1, 5, 10 or 50 available.
