Purpose-built server

The Dell EMC PowerEdge R740 is a 2U rack server configured with two Intel Gold 6126 processors at 2.6 GHz, each providing 12 cores and 19.25M cache. It ships with 256 GB of DDR4 memory across 16 modules running at 2666 MT/s and includes an H730P RAID controller with 2x 1.2 TB 10K SAS drives.

Upgrade path

This configuration replaces an older 2U platform that lacks PCIe Gen 3 expansion capacity or 10 Gb networking. The jump is worth it when workloads need up to eight PCIe Gen 3 slots and dual 10 Gb RJ45 ports from the Intel X550 NDC for higher throughput.

Capacity and limits

The 256 GB DDR4 installation and 12-core CPUs comfortably handle virtualisation clusters and database instances that fit in memory. Storage headroom is limited to eight 2.5-inch bays; only two are populated with 1.2 TB SAS drives, so capacity runs out quickly for large datasets.

Questions about this item

What rack depth and rail kit does the 2U R740 chassis require for mounting?

The server is a 2U rack unit that ships with rails included; it fits standard 19-inch racks and the supplied rails support tool-less mounting in square-hole or threaded cabinets.

How are the 16 DDR4 DIMMs installed across the two Gold 6126 processors, and which slot-population rule is commonly missed?

Each CPU has 12 memory channels; the 16x 16GB modules must be spread evenly — eight per processor — following the documented channel sequence so both CPUs have balanced memory.

When will the 1.2TB 10K SAS drives or the H730P controller battery need replacement?

The 10K SAS drives are rated for continuous operation and typically last several years; the H730P RAID controller uses a lithium-ion battery backup that should be replaced every 3 to 5 years to preserve write-cache protection.
