The EA storage series rackmount not only has the stylish appearance, but the functionality and flexibility make EA series a new breed of disk array. The storage rack offers similar performance and capability at much lower cost per GB storage. In addition, the storage chassis can also be easily reconfigured, modified or upgraded at any time to meet your new application without investing into new storage devices. With one additional 5.25? bay in the rear, EA-2M8EXP-JB is able to equip a 5.25? SAS expander to increase your storage capacity using daisy chain. The storage rack is an ideal platform for creating a custom storage solution with multi-terabytes capability for video storage or editing, data archiving, uninterruptible storage, storage farm or any application that requires high performance and high storage capacity. We also provide redundant power supply to ensure total up time of mission critical server applications.
