Silver 2U rackmount chassis with eight hot-swap drive bays and three 80mm fans

Silverstone

Silverstone RM22-308 2U 8-bay 2.5"/3.5" SAS/SATA server chassis

SKU CH-HKTH-VJVH4 MPN RM22-308

2U rackmount chassis holds eight hot-swap 2.5" or 3.5" SAS/SATA drives with 12 Gb/s Mini-SAS HD SFF-8643 backplane

  • Eight hot-swap bays for 2.5" and 3.5" SAS/SATA drives
  • Backplane with 12 Gb/s Mini-SAS HD SFF-8643 and SGPIO
  • Three 80 x 38 mm hot-swappable PWM fans for cooling
  • Independent drive status LEDs for quick monitoring
  • Fits E-ATX or SSI-EEB motherboards in 2U rack space

Storage Density

The Silverstone RM22-308 is a 2U rackmount chassis that holds eight hot-swap trays for 2.5" or 3.5" SAS and SATA drives. A Mini-SAS HD SFF-8643 12 Gb/s backplane connects every bay and includes SGPIO for drive monitoring. Three 80mm x 38mm hot-swappable PWM fans supply front-to-rear airflow.

Deployment Fit

It suits teams building dense storage nodes on E-ATX or SSI-EEB motherboards who need seven low profile PCI or PCIe slots for HBAs or NICs. The auto-lock handle secures the unit in standard racks without tools. Buyers needing full-height cards or more than eight drive bays should look elsewhere.

Deciding Spec

The backplane uses a 12 Gb/s Mini-SAS HD SFF-8643 interface, so the host controller or HBA must provide matching ports and cable support. Without that link the eight bays cannot communicate at rated speed. Verify your controller specification before purchase.

Questions about this item

How do I install the Mini-SAS HD SFF-8643 12 Gb/s cables to the backplane, and what step is often missed?

Connect the Mini-SAS HD SFF-8643 cables from your HBA to the backplane ports, then attach the 4-pin peripheral power connectors to the backplane — the power step is frequently overlooked.

Which components will need replacement after extended operation?

The three 80mm x 38mm hot-swappable PWM fans are the primary moving parts and should be monitored for bearing wear or reduced airflow over time.

What thermal limit appears first when all eight drive bays are fully loaded under sustained write workloads?

Drive temperatures rise first; the three 80mm fans must maintain adequate airflow across both 2.5" and 3.5" drives to prevent throttling.
