2U dual-socket rack server

The PowerEdge R740 is a 2U rack server fitted with two Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. It ships with 768 GB of DDR4 registered ECC memory across 24 slots and includes a PERC H730P RAID controller with 2 GB cache. Dual 750 W redundant power supplies and iDRAC9 Enterprise remote management are also installed.

From single-socket or older 14G platforms

This system replaces a single-socket server or an earlier 14G generation when workloads need 32 total cores and 768 GB of memory. The jump is worth it for virtualisation clusters, database nodes or compute-heavy applications that exceed the core count and memory capacity of a single-processor box. Buyers who need more than two sockets or a newer processor generation should look elsewhere.

768 GB DDR4 with room to 3 TB

The installed 768 GB (24× 32 GB) DDR4 2666 MHz handles large virtual-machine fleets, in-memory databases and heavy analytics workloads. Headroom remains with support up to 3 TB across the 24 DIMM slots. Eight 300 GB 10K SAS drives on the H730P provide fast local storage for OS and active data; capacity-bound archives or all-flash arrays will need additional shelves or a different chassis.

Perguntas sobre este artigo

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

The server is a 2U rack chassis and ships with Ready Rails for installation in a standard rack enclosure.

How are the two Xeon Gold 6142 processors and 24 DIMMs installed, and what step is often missed?

Both LGA 3647 sockets are already populated with the 16-core CPUs; the 24 DDR4 slots are filled with 32 GB modules, so no further CPU or memory installation is needed.

Which components in the R740 are hot-swappable and will need replacement over time?

The eight 2.5-inch SAS drives, both 750 W power supplies and the PERC H730P controller battery are hot-swappable and are the parts most likely to require later replacement.
