DELL PowerEdge R740xd2 2U rack server 2× Xeon Gold 6230 2.1GHz 20-core 512GB DDR4 26× 4TB SATA HBA330

Dense 2U storage server

The Dell PowerEdge R740xd2 packs twenty-six 3.5-inch bays into a 2U rack form factor. Two Xeon Gold 6230 processors deliver twenty cores each at 2.1 GHz with 3.9 GHz turbo. 512 GB of DDR4-2666 ECC memory fills sixteen slots. The HBA330 controller presents the drives to the operating system without hardware RAID abstraction.

SATA throughput and controller limits

Each drive connects through a 6 Gb/s SATA interface to the HBA330, which aggregates traffic over a 12 Gb/s SAS backplane link. Twenty-six simultaneous streams can saturate the controller uplink, so sustained sequential workloads will hit that ceiling. The dual-port 10/25 GbE mezzanine card and 1 GbE LOM provide network egress, but storage bandwidth remains bound by the HBA330 topology.

Verify rack depth and power infrastructure

The chassis requires a cabinet deep enough for a 2U node with front-loading 3.5-inch trays and rear cabling for two 1100 W platinum supplies. Confirm that your PDU delivers redundant feeds and that the facility cooling handles the thermal load of twenty-six spinning disks plus dual CPUs. iDRAC 9 Enterprise is licensed for remote management; ensure your network segment reaches the dedicated management port.
