DELL PowerEdge R740 2x Gold 6126 12C 256GB 4x 800GB SAS SSD H730P

Dell PowerEdge R740 dual Gold 6126 server

The Dell PowerEdge R740 is a 2U rack server built around two Intel Gold 6126 processors, each with 12 cores at 2.6GHz. It ships with 256GB of DDR4 memory in 16 modules and four 800GB SAS SSDs managed by an H730P RAID controller. This configuration targets virtualisation hosts, database nodes and compute clusters that need strong multi-threaded performance in a dense form factor.

Installation notes for the R740

The chassis provides eight 2.5-inch drive bays so the four installed SSDs leave room for expansion without extra enclosures. Rails and power cords are included, easing rack mounting in standard cabinets. The 1100W redundant power supplies are hot-plug, but the server has no optical drive so OS installation relies on USB or network boot via iDRAC9 Enterprise. Verify PCIe Gen 3 slot clearance for any add-in cards before closing the chassis.

Practical limits of the platform

The memory subsystem runs at PC4-2666 speeds across 16 populated DIMM slots, leaving no free slots for further RAM upgrades without replacing modules. Network I/O is fixed to the onboard Intel X550 controller delivering two 10Gb RJ45 and two 1Gb RJ45 ports; additional NICs consume PCIe slots. Storage growth is capped at eight 2.5-inch bays and the H730P controller, so larger capacity SAS drives are the only internal expansion path.
