Dual-socket Xeon Gold 6126 server

The Dell PowerEdge R740 is a 2U rack system equipped with two Intel Xeon Gold 6126 processors running at 2.6GHz. Each CPU provides 12 cores and 19.25MB cache, giving 24 cores total for multi-threaded workloads. The chassis supports up to eight 3.5-inch drive bays and ships with 256GB of DDR4 ECC registered memory. Remote management is handled by iDRAC9 with an Enterprise licence.

Suited for virtualisation hosts and database nodes

This configuration fits buyers who need dual-socket compute density, large memory capacity and flexible 3.5-inch storage in a standard rack. It is not for buyers who need GPU acceleration, single-socket platforms or 2.5-inch drive bays. The PERC H730P controller manages SATA drives in RAID, and dual 750W supplies provide redundancy.

256GB DDR4 ECC registered memory installed

The system arrives with 256GB of DDR4 ECC registered RAM across the available slots, leaving headroom toward the 3TB maximum. Memory type and speed are fixed to DDR4; other generations will not fit. Confirm the installed capacity matches the application requirement before ordering.

商品問答

How do I install the 2.6 GHz Xeon Gold 6126 processors and what step is often missed?

Seat both 12-core CPUs in the two sockets, apply thermal paste evenly, then torque the heatsink screws in a cross pattern; the step most often missed is updating the iDRAC9 firmware before first boot so the new microcode loads correctly.

What maintenance will the PERC H730P RAID controller and 750 W power supplies need later?

The H730P uses a lithium-ion cache battery that typically lasts three to five years — replace it when iDRAC9 reports a voltage drop; each 750 W PSU has an internal fan that should be cleaned annually and swapped if bearing noise appears.

What limit appears first when the eight 3.5-inch SATA bays run sustained write workloads?

The 10 GbE 562T dual-port adapter saturates at roughly 10 Gbps aggregate throughput, so network bandwidth becomes the bottleneck before the PERC H730P or the 256 GB DDR4 memory ceiling is reached.
