Dense 1U Dual-Socket Platform

The PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6142 processors, each delivering sixteen cores at 2.6 GHz with a 3.7 GHz turbo frequency. Sixty-four gigabytes of DDR4 2666 MHz registered ECC memory are installed across four slots, leaving twenty free DIMM positions for future expansion.

Suited For Virtualisation And Database Workloads

This configuration suits teams running virtualisation clusters, in-memory databases or high-throughput storage tiers that benefit from the integrated PERC H730P controller and eight enterprise SATA SSDs. Buyers who need GPU acceleration, more than sixty-four gigabytes of memory out of the box or a different drive interface should evaluate other platforms.

Eight 800 GB SATA SSDs With Hardware RAID

The single specification that decides fit is the storage subsystem: eight 800 GB SATA solid-state drives managed by a Dell PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. This array delivers the capacity, redundancy and controller features required for mixed read-write workloads in a 1U form factor.

Questions about this item

How are the 2.5" SSDs installed in the 8-bay front panel and which step is often missed?

Slide each 800GB SATA SSD into a front hot-swap bay until the carrier clicks; the step often missed is pressing the release latch fully so the drive seats on the backplane connector.

What maintenance will the PERC H730P controller need over time?

The controller's 2GB cache is backed by a battery that will eventually lose capacity and should be replaced when iDRAC 9 Enterprise reports a battery health warning.

At what point does the 750 W redundant power supply become the limiting factor under sustained load?

With two Xeon Gold 6142 CPUs at 2.6 GHz, 64 GB DDR4, eight SSDs and the X520/I350 card, sustained full-load power can approach the 750 W per supply rating, making PSU capacity the first limit.
