Dense 2U storage server

The Dell PowerEdge R740xd2 packs twenty-six 3.5-inch bays into a 2U rack frame, delivering over one hundred terabytes of raw SATA capacity. Dual Xeon Gold 6154 processors supply thirty-six cores at 3.0 GHz with 3.7 GHz turbo for parallel workloads. Two hundred fifty-six gigabytes of DDR4-2666 ECC registered memory support data-integrity requirements.

Hot-swap drive access and redundant power

Twenty-six front-accessible trays allow drive replacement without shutting down the chassis. The PERC HBA330 controller presents the drives to the operating system in JBOD or pass-through mode for software-defined storage stacks. Dual 1100 W platinum power supplies share the load and maintain operation if one unit fails.

Remote management and high-speed networking included

iDRAC 9 Enterprise provides out-of-band console, power control and firmware updates over a dedicated network port. A Broadcom 57414 dual-port 10/25 Gb SFP28 OCP 2.0 mezzanine card adds low-latency connectivity for clustered storage or backup targets. The front bezel and sliding rails are not supplied and must be sourced separately.

Questions about this item

What SATA speed does the PERC HBA330 controller support for the 26 installed 4TB drives?

The controller runs at 12Gb/s SAS/SATA, so each 3.5-inch 7.2K drive connects at 6Gb/s SATA.

How many DDR4 memory slots are free after the factory 256GB configuration?

Eight of the 16 slots are populated with 32GB modules, leaving eight slots available for expansion up to 1TB total.

Which firmware step is often missed when adding the 57414 dual-port 10/25Gb mezzanine card?

After seating the OCP 2.0 card, update iDRAC 9 Enterprise and the card firmware before configuring the SFP28 links.
