Chassis drive-bay layout

This Dell PowerEdge R640 is a 1U rack server equipped with four 3.5-inch LFF drive bays and a PERC H740P RAID controller. Dual Xeon Gold 5218 processors deliver 16 cores each at 2.3 GHz, backed by 64 GB of DDR4 ECC registered memory. iDRAC9 Enterprise remote management and a 10 GbE 562T dual-port adapter are included.

Fit for dense storage, not for scale-out compute

The four-bay LFF chassis suits workloads that need high-capacity SATA drives in a single rack unit, such as backup targets or media archives. Buyers who require more than four large-form-factor drives or who need a GPU-accelerated platform should evaluate other form factors.

Four 3.5-inch bays and PERC H740P decide storage fit

The server supports a maximum of four 3.5-inch SATA drives managed by the PERC H740P controller, so the drive-bay count is the primary constraint for any storage design. Memory can scale to 7.68 TB of DDR4 across 24 DIMM slots when the application demands it.

Questions about this item

How many 3.5" drives can the R640 4LFF chassis hold before storage expansion stops?

The chassis supports up to four 3.5" SATA drives, so that is the physical limit for internal bays.

What is the installed power supply rating and how many units are fitted?

Two 750 W power supplies are installed, providing redundant power for the dual Xeon Gold 5218 CPUs.

Which DDR4 memory generation and form factor must already be on hand for upgrades?

The system uses DDR4 ECC Registered DIMMs, so any additional modules must match that specification.
