Dell PowerEdge R640 4LFF dual Xeon Silver 4210

The Dell PowerEdge R640 4LFF is a 1U rack server fitted with two Intel Xeon Silver 4210 processors running at 2.2GHz, each providing 10 cores and 13.75 MB cache. It ships with 256GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The chassis holds up to four 3.5-inch SATA drive bays and includes a 10GbE 562T dual-port adapter. Integrated graphics handle display output. This configuration suits virtualisation hosts, database nodes or compute clusters that need dense CPU and memory capacity in a single rack unit.

Four 3.5-inch SATA bays

The server provides four hot-plug 3.5-inch bays wired for SATA drives and managed by the PERC H740P RAID controller. No drives are installed, so capacity and redundancy depend entirely on the disks you add. The controller supports hardware RAID levels but the maximum array size and drive count are capped by the four physical bays. Memory can scale to 7.68TB of DDR4 across 24 DIMM slots, though only 256GB is populated today. Network throughput is limited to the two 10GbE ports supplied by the 562T adapter.

Verify rack depth, power feeds

The unit measures 36 x 24 x 10 inches and weighs 40 pounds, so confirm your rack depth and weight allowance. Dual 750W power supplies require two compatible PDU circuits; check voltage and connector type in your facility. Because no drives are included, you must source 3.5-inch SATA HDDs or SSDs that match your capacity and RAID plans. Rail kits are available on request but are not bundled. Remote management uses iDRAC9 Enterprise, so ensure your management network can reach the dedicated iDRAC port.

Questions about this item

Which drive capacity should I select for the 3.5" bays?

The chassis provides four 3.5-inch bays that accept SATA hard drives; choose capacities that match your storage budget and RAID layout.

What does the 2.2 GHz clock speed deliver with two 10-core Xeon Silver 4210 CPUs?

Twenty cores running at 2.2 GHz give strong multi-threaded throughput for virtualization, databases and general compute workloads.

How does the PERC H740P controller limit drive performance?

The PERC H740P manages the SATA-connected drives, so throughput is capped by the SATA link speed of the installed drives.
