Fault-tolerant JBOD in a Compact 1U Chassis:

The B12S-J1000-R/S dual-/single-controller JBOD provides you the ease of easily attaching terabytes of capacity to the B12S and B12F RAID series. The B12S-J1000 houses 2.5-inch SAS interface disk drives. With data paths routed from dual-ported SAS drives, to the SAS expanders on JBOD controllers, and to the host ports, data access is safe from single point of failure.

Thanks to the low vibration and reduced airflow requirements of 2.5-inch drives, the B12F runs with higher reliability.

Expansion Links: Expansion over SAS Wide Links:

Similar to Fibre Channel expansion loops, SAS expander technologies also enable the ease of connections when the need arises for more capacity. All you have to do is to attach the cables and use a flatblade screwdriver to select an enclosure ID by a rotary switch. The SAS WWN addresses will be automatically applied to all the disk drives.

• A single-controller RAID can attach to 4 expansion enclosures (60 HDD) via SAS wide links.
• A redundant-controller RAID can attach to 3 expansion enclosures. Although the maximum no. of disk drives is reduced to 48, yet fault-tolerant links can be strung between RAID and JBOD enclosures.

Total Capacity with Expansion:

Up to 9TB (Max. Capacity Configuration - using 60 2.5-inch SAS HDD in single-controller RAID and JBOD)

- or -

7.2TB (Fault Tolerance Configuration - using 48 2.5-inch SAS HDD in dual-controller RAID and JBOD)

Scalability:

Redundant-controller RAID – 3 JBOD

Single-controller RAID – 4 JBOD
1U JBOD - Up to 4 JBOD for a total of 60 HDD
