Storage density and controller

The Dell PowerEdge R740xd2 is a 2U rack server designed for data-intensive workloads that demand high-capacity storage in a compact form factor. It provides twenty-six 3.5-inch drive trays and a PERC H330 controller supporting SAS and SATA drives. Dual Xeon Gold 6254 processors deliver thirty-six total cores at 3.1GHz with 4.0GHz turbo for compute-heavy tasks.

Suitable and unsuitable buyers

This server suits organisations building software-defined storage clusters, backup repositories or media archives that need dense 3.5-inch capacity and redundant 1100W power supplies. It does not suit buyers who require installed drives, a front bezel or ready rails included, or workloads needing more than two processors or memory beyond 1TB.

Deciding specification

The PERC H330 storage controller operates at 12Gb/s SAS and SATA without RAID cache, so the choice hinges on whether your deployment can use software-defined RAID or requires a hardware RAID card with dedicated cache.

Questions about this item

What rack depth and rail kit does the 2U R740xd2 need for mounting?

The server occupies 2U of rack height and requires sliding rails; the front bezel and Ready Rails are not included in the box.

How do I install the 26 front 3.5-inch drive trays and what step is commonly missed?

Trays slide into the front bays and lock with the latch; the common miss is forgetting to seat the tray fully until the latch clicks, which leaves the drive disconnected from the backplane.

When will the two 1100 W platinum power supplies or the H330 controller battery need replacement?

The 1100 W hot-swap PSUs are rated for continuous operation and typically last several years; the PERC H330 uses a super-capacitor cache backup that does not require a replaceable battery.
