Dense 1U Compute Platform

The Dell PowerEdge R640 is a rackmount server system built for virtualization, databases, and high-speed transactional workloads. Two Intel Xeon Gold 6136 processors deliver 24 total cores and 48 threads at a 3.00GHz base frequency. The configuration includes 512GB of DDR4 ECC Registered memory and eight 1.2TB 10K RPM SAS drives managed by a PERC H740P controller.

Fit for Virtualization and IOPS-Heavy Tasks

This system suits teams running mid-tier virtualization clusters, IOPS-intensive storage workloads, or compute-driven applications that benefit from high core counts and fast SAS storage. Buyers who require more than two processor sockets, larger memory capacity than 3TB, or additional drive bays beyond the eight 2.5-inch slots should evaluate larger platforms.

Dual 10GbE Network Foundation

Dual 10GbE X540 ports paired with dual 1GbE I350 interfaces provide the high-throughput networking needed for virtual machine migration, storage replication, and dense rack deployments. This connectivity profile determines whether the server matches the bandwidth requirements of the target environment.

Questions about this item

What networking speeds do the X540 and I350 controllers provide?

The X540 gives dual 10GbE ports and the I350 gives dual 1GbE ports, so the highest wired throughput available is 10GbE.

What rack space and rails does this 1U server need?

It occupies 1U of rack height and requires sliding rails compatible with the R640 chassis; the unit weighs 60kg so the rack must support that load.

How are the drives installed and what is the common mistake?

The eight 2.5-inch hot-swap bays are front-loading; the step often missed is fully seating each carrier until the latch clicks so the SAS connector engages.
