Two-socket 2U rack server with 512 GB DDR4 memory and PERC H730P storage controller
The Dell PowerEdge R740 is a 2U rack server built around two Intel Xeon Platinum 8160 processors running at 2.1 GHz with 24 cores each. It ships with 512 GB of DDR4 registered ECC memory across 16 slots and a PERC H730P controller with 2 GB cache. Dual 750 W platinum power supplies, iDRAC 9 Enterprise, quad-port 1/10 GbE networking, rails and bezel complete the unit.
This configuration fits buyers who need high core counts and large memory capacity in a 2U form factor with redundant power and hardware RAID. It is not for buyers who need more than two processor sockets, GPU accelerator support, or single-thread frequencies above 3.7 GHz. The eight 2.5-inch drive bays limit internal storage to the two installed 300 GB 10 K SAS drives unless additional drives are sourced separately.
The system arrives with 512 GB of DDR4 2666 MHz registered ECC memory populated in 16 of 24 DIMM slots, leaving room to scale toward the 3 TB maximum. This memory capacity is the primary factor in determining whether the server can hold the working set for your virtualisation or in-memory database workload without immediate expansion.
