Silverstone RM43-324-RS 4U 24-bay server chassis

High-Density 4U Storage Chassis

The SilverStone RM43-324-RS is a 4U rackmount server chassis designed for professional storage environments. It provides twenty-four hot-swappable drive bays that accept both 2.5" and 3.5" SAS or SATA drives. The integrated backplane connects each bay through Mini-SAS HD SFF-8643 interfaces running at 12 Gb/s per lane. Ball-bearing sliding rails and an auto-lock handle simplify installation in standard server cabinets.

Suited For High-Capacity SAS/SATA Arrays

This chassis suits builders who need maximum drive density in a 4U form factor with 12 Gb/s SAS/SATA backplane connectivity. It also supports E-ATX or SSI-EEB motherboards and seven full-height PCIe slots for RAID controllers or networking cards. Buyers who require direct PCIe backplane connectivity or a different motherboard form factor should look at other platforms. The three included 120mm x 38mm hot-swap PWM fans handle cooling for dense drive configurations.

24-Bay 12 Gb/s SAS/SATA Backplane

The defining specification is the twenty-four-port backplane that delivers 12 Gb/s bandwidth per lane over Mini-SAS HD SFF-8643 connectors with SGPIO support. This density increase over the previous 20-bay design determines whether the chassis matches a given storage capacity requirement. Power supply flexibility for ATX, mini-redundant or 2U redundant units supports varied deployment scenarios.
