Server configuration and purpose

The Dell PowerEdge R640 is a 1U rack-mount server fitted with two Intel Xeon Silver 4210 processors running at 2.2GHz and 512GB of DDR4 ECC registered memory. A PERC H740P RAID controller and a dual-port 10GbE 562T adapter are installed, while the eight 2.5-inch drive bays ship empty for custom storage selection. Dual 750W power supplies and iDRAC9 Enterprise remote management complete the platform.

Fit and alternatives

This system suits workloads that benefit from twenty cores, large memory capacity and hardware RAID in a single rack unit. Buyers who require GPU acceleration, more than eight drive bays or a different memory generation should evaluate other chassis options. The integrated graphics provide basic display output only.

Deciding specification

The installed 512GB DDR4 ECC registered memory determines whether the server can hold the working set for virtualization, database or high-performance computing tasks. Maximum supported capacity reaches 7.68TB when all slots are populated with compatible modules.

Questions about this item

Should I choose the 8SFF chassis with 2.5" bays or a different drive-count version for this R640?

This unit is the 8SFF chassis that supports up to eight 2.5" drives; choose it when you need maximum bay density in a 1U rack space.

What does the 2.2 GHz clock on the two Xeon Silver 4210 CPUs deliver in actual workloads?

Two 10-core Xeon Silver 4210 processors at 2.2 GHz provide 20 total cores and 13.75 MB cache per CPU for multi-threaded applications and virtualization.

How does the PERC H740P controller and SATA interface limit drive performance?

The PERC H740P RAID controller manages SATA drives at up to 6 Gb/s per port, capping throughput to the SATA III link speed for each installed disk.
