PowerEdge R640 4LFF single Xeon 4216 server

This Dell PowerEdge R640 is a 1U rack server populated with one Intel Xeon Silver 4216 processor running at 2.1 GHz with 16 cores and 22 MB cache. It ships with 64 GB of DDR4 ECC registered memory and a PERC H740P RAID controller. The chassis provides four 3.5-inch drive bays using a SATA interface, and no drives are installed. Integrated 10 GbE networking is provided by a dual-port 562T adapter, and remote management uses iDRAC9 Enterprise.

Suits single-socket workloads needing four

This configuration fits workloads that run on a single 16-core Xeon and require up to four 3.5-inch SATA drives with hardware RAID. Buyers who need dual-processor compute, more than four drive bays, or a different drive interface should look elsewhere.

Four 3.5-inch SATA bays with PERC H740P RAID

The chassis supports exactly four 3.5-inch drives connected through the PERC H740P controller, which is the single specification that determines whether this server matches your storage topology.

Questions about this item

What rack depth and clearance does the 36 in deep R640 4LFF chassis require?

The chassis measures 36 inches deep by 24 inches wide by 10 inches high and weighs 40 units; a rail kit is available on request for standard rack mounting.

What is the correct order for installing the Xeon Silver 4216 processor and the 64GB DDR4 memory modules?

Install the single Xeon Silver 4216 into socket 1 first, then populate the DDR4 slots following the documented memory-channel sequence; the system supports a second processor for future expansion.

Which components in the PERC H740P RAID controller and the 750W power supplies may need replacement over time?

The PERC H740P includes a battery-backed cache module that degrades after several years, and each 750W supply contains internal fans and capacitors that typically require replacement on a multi-year cycle.
