Dual-socket 1U compute density

The PowerEdge R640 fits two Intel Xeon Platinum 8160 processors into a single rack unit. Each CPU delivers 24 cores at 2.1 GHz with a 3.7 GHz turbo frequency. The system ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules. It is built for scale-out workloads that demand high core counts in minimal rack space.

Storage controller and drive bay constraints

The PERC H730P controller supports SAS and SATA drives with RAID levels 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Only eight 2.5-inch drive bays are available, limiting raw capacity to the number of physical disks installed. The unit includes two 300 GB 10K SAS drives. Buyers who need more storage than eight bays provide must look elsewhere.

Memory ceiling and slot count

Maximum supported memory is 3 TB spread across 24 DDR4 slots. The current 128 GB configuration occupies eight slots, leaving 16 slots open for future expansion. Workloads that will exceed 3 TB of RAM cannot be accommodated by this platform.

Questions about this item

Should I pick the dual 24-core Xeon 8160 configuration or a single-processor alternative?

The server ships with both sockets populated by 24-core Xeon 8160 CPUs at 2.1 GHz, reaching 3.7 GHz turbo; the board supports a maximum of two processors, so no single-CPU option exists for this unit.

What does the 128 GB DDR4 2666 MHz ECC memory mean for actual workloads?

Eight 16 GB registered ECC modules fill eight of twenty-four slots, giving 128 GB at 2666 MHz with headroom to expand up to 3 TB for larger datasets or virtualisation.

How does the PERC H730P 12 Gb/s SAS controller limit drive performance?

The H730P provides 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through at 12 Gb/s SAS, capping throughput at the controller and backplane level rather than the individual 300 GB 10K drives.
