Dual Xeon Gold 6148 2U Server

This Dell PowerEdge R740 is a 2U rack server equipped with two Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores. It includes 128 GB of DDR4 registered ECC memory across eight 16 GB modules and eight 1.2 TB 10K SAS hard drives managed by a PERC H730P RAID controller with 2 GB cache. Dual 750 W redundant power supplies and iDRAC 9 Enterprise remote management come standard.

Virtualisation and database workloads

The dual 20-core CPUs and 128 GB of DDR4 suit virtualisation hosts, database servers and compute-heavy applications that benefit from high core counts and redundant power. Buyers needing more than 3 TB of memory or more than twenty-four DIMM slots should look elsewhere. The eight 2.5-inch drive bays limit internal storage to the installed SAS drives unless external enclosures are added.

3 TB maximum DDR4 capacity

The Intel C620 chipset supports up to 3 TB of DDR4 registered ECC memory across twenty-four slots, so the installed 128 GB leaves ample room for future expansion. This ceiling is the decisive figure when planning memory-heavy workloads on this platform.

Questions sur cet article

How do I install the 8x 1.2TB SAS drives and the PERC H730P controller, and what step is often missed?

Slide each 2.5-inch drive into the hot-swap bays until it clicks, then cable the H730P to the backplane; the step often missed is importing the foreign configuration in the controller BIOS before creating the RAID volume.

Which components will need replacement first during the server's life?

The 10K SAS hard drives and the H730P controller's battery-backed write cache are the primary wear items; the redundant 750W power supplies and system fans are also field-replaceable units.

What thermal or power limit appears first when both Xeon Gold 6148 CPUs run at sustained load?

The 750W platinum power supplies set the hard ceiling; with both 20-core processors at 2.4GHz base (3.7GHz turbo) the platform can hit that limit before the cooling capacity is exceeded.
