Compatible with select EonStor DS 3000 and EonNAS 3000 systems, this 24-bay 2U rackmount enclosure conveniently expands storage with support for SAS, NL-SAS, and SATA drives. Choose from a single controller configuration (JB 2024SB) or a dual controller setup for higher data availability (JB 2024RB), with two enterprise-class 6Gb/s SAS 4x wide ports per controller. JB 2024B expansion enclosures ship with dual redundant 530W hot-swap power supplies to ensure continuous operation, resulting in a highly efficient and space-saving path to capacity growth.

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.
