Purpose-built 1U rack server

The Dell EMC PowerEdge R640 is a 1U rack server designed for business workloads such as virtualization, databases, backups and application hosting. It ships with two Intel Xeon Gold 6134 processors running at 3.20 GHz, providing 16 cores total with Turbo Boost up to 3.70 GHz. The system includes 128 GB of DDR4 ECC registered memory across 24 slots and supports up to 3 TB maximum capacity.

Suited for dense virtualization hosts

This configuration fits environments that need high core density and fast SAS storage in a single rack unit, backed by the H740P RAID controller and four 1 GbE RJ45 ports. Buyers who require GPU acceleration, 10 GbE or faster networking, or more than 3 TB of memory should look at alternative platforms. The fixed 1U form factor also limits PCIe expansion compared with larger chassis.

Deciding spec: 8× 1.2 TB 10K SAS drives

Eight 1.2 TB 10 000 RPM SAS hard drives deliver the capacity and throughput that determine whether this server matches your storage profile. The H740P controller with 8 GB cache manages RAID levels for operating systems, applications, virtual machines and backups. If your workload demands solid-state latency or larger drive bays, this drive set is the limiting factor.

Questions about this item

What rack height and power setup does the 1U PowerEdge R640 need to operate?

The server occupies 1U of rack space and includes redundant hot-swap power supplies, so it requires a rack that accepts 1U servers and can deliver power to both supplies.

Can the existing H740P controller manage the eight 1.2 TB SAS drives together with older SAS drives I want to keep?

The H740P supports SAS connectivity and can incorporate additional SAS drives into its RAID configuration alongside the eight 1.2 TB 10K drives already installed.

How can I confirm both Xeon Gold 6134 CPUs and all 128 GB of DDR4 ECC memory are recognised after installation?

During POST the system will display two processors with 16 total cores at 3.20 GHz and show 128 GB of DDR4 ECC Registered memory; the iDRAC or BIOS system inventory can also verify these figures.
