Supermicro CSE-946ED 4U 90 bay JBOD 12Gb/s

The Supermicro JBOD expansion systems can be equipped with up to 90 SAS or SATA hard drives and set a new standard on just 4U. Nearly one PetaBytes can be realized while using hard disk drives from the newest available standard. Equipped with four powerful Mini-SAS HD interfaces the system is connected to one or more hosts. It is also possible to operate within a high available cluster structure. The overall performance of the system is significantly facilitated by the internal SAS-3 system architecture. Through the speed of hard drives with up to 12 GB/s, via the external SAS system interface the data rate can be more than 20 GBytes to the connected hosts.

The areas of application of highly capacitive JBOD storage systems can be found in data centers for enterprise companies, providers and science, but also in environments that use the power of Windows Server 2012. Especifically here storage capacities can build up with JBOD systems over scale-out file server in a no- single-point-of-Failure (NSPoF), which offer a huge capacity to productive servers.
