Dell PowerEdge R640 4LFF Configuration

This Dell PowerEdge R640 server arrives in a 4LFF chassis supporting up to four 3.5-inch drive bays. It is built for organisations that need dense compute in a 1U rack form factor. Two Intel Xeon Silver 4116 processors and 128GB of DDR4 ECC registered memory are installed. The system ships without storage drives.

Suits Virtualisation Hosts and Database Nodes

The dual-socket design with twenty-four total cores suits virtualisation clusters, database workloads and general-purpose compute. Buyers who require GPU acceleration should look at a different platform because this unit provides only integrated graphics. Teams needing more than four drive bays or a larger chassis will need another model.

PERC H740P RAID Controller Decides Storage Layout

The installed Dell PERC H740P controller manages the SATA drives you add to the four 3.5-inch bays. It determines which RAID levels and cache policies are available. Confirm that this controller matches your storage topology before ordering.

Questions about this item

What drive-bay size and count does the 4LFF chassis provide for 3.5-inch drives?

The chassis supports up to four 3.5-inch drive bays for SATA hard drives.

How are the two 750-watt power supplies installed, and what step is often missed?

Both supplies slide into the rear bays until they click; the second supply must be seated fully to enable redundancy.

When should the PERC H740P controller battery be replaced to protect cached writes?

Replace the controller battery every three to five years or when iDRAC9 reports a degraded battery status.
