ASRock Rack 2U4N-F/C621-M3 2U 4-node barebone server

Dense Compute Platform

The ASRock Rack 2U4N-F/C621-M3 is a 2U rackmount barebone that houses four independent server nodes. Each node accepts up to two LGA 3647 processors and provides six-channel DDR4 memory across sixteen DIMM slots. A 1600 W redundant power supply and sixteen 2.5-inch drive bays are shared across the chassis.

Target Deployment Fit

This platform suits builders creating high-density clusters for virtualisation, HPC or cloud workloads where many nodes share rack space and power. Operators needing GPU acceleration, OCP 3.0 mezzanine cards, or more than two PCIe 3.0 x16 slots per node should evaluate other form factors.

Deciding Specification

Each node delivers two PCIe 3.0 x16 low-profile slots and four SATA 600 ports with an option for two NVME devices. That expansion layout determines whether the node can host the required accelerators, storage controllers or networking cards for the intended workload.
