2U 8-bay rackmount chassis

The Silverstone RM22-308 is a 2U rackmount storage chassis designed for servers or workstations needing high-density drive capacity. It accepts eight hot-swap trays compatible with both 2.5" and 3.5" SAS or SATA drives. The backplane uses a 12 Gb/s Mini-SAS HD SFF-8643 interface with SGPIO signalling. This unit suits IT managers building compact storage arrays.

Tool-less trays and hot-swap fans

Drive installation uses tool-less trays that slide into the front bays for quick hot-swap replacement. Three 80mm x 38mm PWM fans are also hot-swappable, allowing maintenance without powering down the system. The backplane provides independent drive status LEDs for immediate fault identification. Builders must verify that their host controller supports the Mini-SAS HD SFF-8643 connector and 12 Gb/s SAS signalling.

Sustained airflow for dense arrays

The three included PWM fans deliver continuous airflow across all eight drive slots during prolonged read and write workloads. Hot-swap fan design lets a failed unit be replaced while the chassis remains operational, maintaining thermal stability. The 2U form factor fits standard racks supporting E-ATX or SSI-EEB motherboards. Environments requiring redundant power supplies or deeper chassis clearance should review their rack specifications before purchase.

Questions about this item

How can I verify the 12 Gb/s Mini-SAS HD SFF-8643 backplane is operating correctly after installation?

Check each drive status LED on the front panel; a steady or blinking light confirms the SAS/SATA link is active at 12 Gb/s through the SFF-8643 backplane.

What ships with the RM22-308 and what must I source separately?

The chassis includes three 80 mm × 38 mm hot-swappable PWM fans and eight 2.5"/3.5" hot-swap trays; you must supply an E-ATX or SSI-EEB motherboard, drives, and Mini-SAS cables.

Which RM22-308 configuration should I choose for eight 3.5" SAS drives?

The single 2U 8-bay model supports eight 3.5" SAS/SATA drives on the 12 Gb/s Mini-SAS HD SFF-8643 backplane; no other capacity or version is offered.
