Storage Chassis / U-316HD
3U 16-Bay Storage Server Rackmount Chassis
A 3U sixteen-bay chassis with seven full-height slots — high-capacity RAID and JBOD builds without moving to a 4U footprint.
Product Overview
What the U-316HD is built for.
The U storage server series rackmount has the unique outward appearance design, but the functionality and flexibility make U series a new breed of storage server. Also U series has effective cooling system. As SAS and SATA technology has become a more cost effective solution, we have taken a step forward to prepare the migration of new technology and provide the Slim SAS SFF-8654 12Gb/s,24Gb/s backplane to support both latest SAS and SATA hard drives, and also provide redundant power supply to ensure total up time of mission critical server applications.
