Ready-to-deploy 1U server

The Dell PowerEdge R640 arrives with a single Xeon Silver 4215R processor at 3.2 GHz and 128 GB of DDR4 ECC registered memory. Integrated graphics handle console output while a PERC H740P RAID controller manages storage. The iDRAC9 Enterprise licence provides full remote management from day one.

Four 3.5-inch drive bays and dual 750 W supplies

The 4LFF chassis accepts up to four SATA hard drives that are not included, leaving capacity and RAID level entirely to the builder. Two installed 750 W power supplies deliver redundancy for the single CPU configuration. A second processor socket remains open for future expansion up to the platform maximum.

Sustained workloads in a compact rack footprint

The 1U form factor measures 36 x 24 x 10 inches and weighs 40 pounds, fitting dense rack rows without special clearance. Dual 10 GbE ports on the 562T adapter maintain throughput during long backup or virtualization windows. Firmware is updated to the latest stable release and every unit passes a full burn-in test before it ships.

Questions about this item

How far can the 128 GB DDR4 be expanded before hitting the R640 ceiling?

The system supports up to 7.68 TB of DDR4 ECC registered memory across its 24 DIMM slots.

What thermal and acoustic load should I expect from the dual 750 W supplies and Xeon Silver 4215R during continuous operation?

The 8-core 3.2 GHz processor and redundant 750 W units are cooled by the R640's managed fan array; iDRAC9 Enterprise provides real-time temperature and power telemetry.

Which drive carriers and backplane does the 4LFF chassis require so I can populate the 3.5-inch bays?

The 4-bay 3.5-inch backplane uses SATA-connected Dell 3.5-inch drive carriers; the PERC H740P RAID controller manages the installed drives.
