Compatible with EonStor DS storage systems, the enterprise-class JB 2048 connects via reliable 6Gb/s SAS and has room for 48 NL-SAS drives within its 4U rack mount form factor. Up to six enclosures can be linked through scale-out support, for a maximum 336 drives. Installation is simple and quick, and the high density storage offered by this sleek JBOD is further guarded by dual redundant 80 PLUS energy-saving power supplies.

Infortrend EonStor DS and EonNAS systems offer easy scalability on demand, allowing you to increase storage capacity when needed. The JB 2000 and JB 3000 series of expansion enclosures (JBODs) are available in multiple form factors, from 2U 12-bay to 4U 60-bay. Their flexibility means they are an excellent choice for diverse environments, budgets, and capacity needs. New generation JB 3000 models deliver extra high speed connectivity to storage systems via 12Gb/s SAS, and all enclosures feature hybrid 2.5”/3.5” drive bays for SSD readiness.

JB 2000 and JB 3000 models are offered in single or high availability dual controller configurations and ship with redundant 80 PLUS power supplies by default. For additional energy savings, they employ smart drive spin-down while maintenance is easy with modular hardware. Assured Infortrend reliability is backed by a 3-year warranty.
