Optimized for mission-critical, enterprise-level storage applications, supermicro's innovative super sbb features a fully redundant, fault-tolerant cluster-in-a-box system. The super sbb supports hot-swap sas hdds with the option to expand by using the sbb jbod. The super sbb provides hot-swappable canisters for all active components. With heartbeat and data connection between the serverboards via the midplane, if one serverboard fails, the other serverboard is able to take over control and access the hdd's (both controllers can also work as active-active mode), keeping the system up and running. Storage software is the key to enable this feature, which is available from several supermicro's partners. Equipped with high-efficiency redundant power supplies and hot-swappable cooling fans, the super sbb is a highly-available, high-reliability storage system at a competitive price.
