Dense 1U dual-socket server

The Dell PowerEdge R640 fits two Intel Xeon Gold 6142 processors and 512 GB of DDR4 memory into a single rack unit. It targets operators who need high core counts in a compact footprint for virtualization or database clusters. Buyers who require more than two sockets or GPU acceleration will need a larger chassis.

16 cores per CPU at 2.6 GHz base

Each Xeon Gold 6142 delivers 16 cores with a 2.6 GHz base frequency and 3.7 GHz turbo. The dual-socket configuration yields 32 total cores for heavily threaded workloads. Systems limited to a single processor or lower core counts cannot match this parallel throughput.

Sustained throughput with redundant 750 W supplies

Dual 750 W platinum power supplies and hot-swap drive bays keep the array and controllers running during extended compute jobs. The PERC H730P controller battery protects cached writes if power fluctuates. Environments without redundant power or battery-backed RAID risk data loss under continuous load.

Questions sur cet article

What does the 3.7GHz turbo on the dual Xeon Gold 6142 CPUs mean for actual workloads?

The two 16-core processors run at a 2.6GHz base and can reach 3.7GHz turbo when thermal headroom allows, giving up to 32 cores of burst performance for compute-intensive tasks.

How does the PERC H730P 12Gb/s SAS controller limit the eight 1.2TB 10K drives in practice?

The H730P connects each 2.5-inch SAS drive at 12Gb/s and supports RAID 0, 1, 5, 6, 10, 50 and 60, so the array topology you choose determines usable capacity and redundancy.

What physical space and mounting hardware does the 1U server require?

The chassis occupies one rack unit, includes ready rails for square-hole or round-hole cabinets, and ships with a front bezel for a clean installation.
