Silverstone RM21-308 2U Storage Chassis

The Silverstone RM21-308 is a 2U rackmount server chassis built for high-density storage. It accepts Micro-ATX motherboards and provides eight hot-swap bays that take 2.5" or 3.5" SAS and SATA drives. A backplane with 12 Gb/s Mini-SAS SFF-8087 connectors and three 80 x 15mm PWM fans are included for cooling and connectivity.

Suits storage-focused Micro-ATX builds

This chassis suits professionals and data-centre engineers building storage servers on a Micro-ATX platform. The eight-bay layout and low-profile expansion slots support dense drive arrays with targeted add-in cards. Builders who need full-height expansion cards or ATX motherboards should look elsewhere.

Eight hot-swap bays with 12 Gb/s Mini-SAS backplane

The defining specification is the eight-bay backplane delivering 12 Gb/s Mini-SAS SFF-8087 connectivity for SAS and SATA drives. This interface and bay count determine whether the chassis matches your storage density and controller requirements.
