Storage Chassis / U-224HD
2U 24-Bay 2.5" Storage Server Rackmount Chassis
A 2U all-flash platform with twenty-four 2.5" hot-swap bays — SSD density for latency-sensitive database and virtualization workloads.
Product Overview
What the U-224HD 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.
