PowerEdge R640 4-bay server

This 1U rack-mount system ships with one Intel Xeon Platinum 8268 processor running at 2.9 GHz across 24 cores and 128 GB of DDR4 ECC registered memory. The chassis provides four 3.5-inch drive bays and a PERC H740P RAID controller. Remote management is handled by iDRAC9 Enterprise.

Suited for dense storage workloads

The four-bay layout fits workloads that need local capacity on 3.5-inch SATA drives while keeping rack depth short. Buyers who need more than four internal drives or a different drive form factor should consider other platforms. The single-socket configuration also limits maximum thread count for heavily parallel tasks.

Four 3.5-inch drive bays decide fit

The chassis supports exactly four 3.5-inch SATA bays with the PERC H740P controller. If the deployment requires more internal bays or a different drive interface, this unit will not satisfy the requirement.

Questions about this item

How much heat does the Xeon Platinum 8268 24-core CPU generate under sustained all-day load?

The installed Xeon Platinum 8268 is a 24-core processor running at 2.9 GHz with 35.75MB cache. Power draw and thermal output scale with workload; the chassis uses dual 750W supplies and integrated cooling designed for continuous operation.

What drive caddies or trays are required to populate the four 3.5-inch bays?

The 4LFF chassis provides four 3.5-inch SATA drive bays. Drives must be mounted in Dell-compatible 3.5-inch hot-plug trays that match the backplane; the PERC H740P controller manages the connected SATA devices.

Will my existing DDR4 ECC registered modules work alongside the 128GB already installed?

The system currently holds 128GB of DDR4 ECC registered memory. Additional modules must match DDR4 ECC registered specification; the platform supports up to 7.68TB total capacity across available DIMM slots.
