Storage density and motherboard support

The Silverstone RM22-312 is a 2U rackmount chassis built to hold twelve hot-swap trays that accept both 2.5" and 3.5" SAS or SATA drives. It fits E-ATX, SSI-EEB and smaller server boards, giving integrators a dense platform for storage-heavy workloads. The backplane connects every bay through three Mini-SAS HD SFF-8643 links running at 12 Gb/s with SGPIO signalling.

Cooling, drive access and expansion

Three 80mm x 38mm hot-swappable PWM fans provide front-to-rear airflow while the system stays online. Each drive tray shows an independent status LED so technicians can identify a failed disk without guesswork. Seven low-profile PCI or PCIe slots sit behind the motherboard area, and two front USB 3.1 Gen 1 Type-A ports give quick local access for diagnostics or media.

CPU cooler height limit

The internal clearance above the socket tops out at 68mm, so only low-profile coolers will fit. Builds that need tower coolers or liquid blocks taller than this cannot use the chassis. The unit ships without a power supply, accepting either a single or redundant 2U module.

Questions sur cet article

What throughput does the Mini-SAS HD SFF-8643 interface cap at for the twelve drive bays?

The backplane connects twelve SAS or SATA drives through three Mini-SAS HD SFF-8643 ports rated at 12 Gb/s each, so the interface ceiling is 12 Gb/s per port.

What motherboard form factors and CPU cooler height does the 2U chassis accept?

It fits SSI-EEB, SSI-CEB, E-ATX, ATX, Micro-ATX and Mini-ITX boards, and the CPU cooler must not exceed 68 mm in height.

How are the three 80 mm PWM fans installed, and what mistake should be avoided?

The fans are hot-swappable; slide each unit into the front fan tray until it clicks, and do not force a fan in upside-down or the PWM connector will not seat.
