Dual Xeon Platinum 8158 blade server

The Dell PowerEdge M640 fits into a standard blade enclosure and delivers two 12-core Xeon Platinum 8158 processors running at 3.0 GHz. It targets datacentre operators who need dense compute for virtualization, database or high-performance workloads in a shared chassis. The 256 GB of DDR4 ECC registered memory supports large working sets without leaving the blade form factor.

Enclosure power cooling and storage

The blade draws power and cooling from the chassis mid-plane so no separate PSU or fans are required. Two 2.5-inch 300 GB 10K SAS drives connect to the onboard PERC H330 RAID controller providing local OS or scratch space. A 10 GbE dual-port 562T adapter handles east-west traffic while iDRAC9 Enterprise gives remote console and lifecycle management over a dedicated network.

Sustained multi-thread throughput

With both sockets fully populated the server maintains its 3.0 GHz base clock across all 24 cores under continuous load, limited only by the enclosure thermal budget. DDR4 bandwidth scales with the dual-channel per CPU design feeding memory-intensive jobs. The SAS drives and H330 controller sustain sequential and random I/O for logging or checkpointing without the latency spikes seen on consumer storage.
