Abstract

Disclosed is an assembly which allows easy integration and testing of a RAID device in a development environment. The assembly plugs into a JBOD (Just a Bunch Of Disks) system and transforms the system into a RAID subsystem which can be tested and run in advance of the RAID controller being integrated into the subsystem. This assembly is composed of a RAID Controller assembly which has a converter PCBA to allow connection into an SCA disk drive connector. The physical parameters of the assembly are modeled after a 3.5" disk drive in thickness and width. Thus, a 3.5" disk drive can be removed from a slot in a JBOD and this assembly can be inserted in its place. Once this is completed, the RAID assembly interfaces to the disk drive bus(es) in the system and connects to a host system via cables attached to connectors on the RAID assembly. The system can now be accessed as a RAID system and an integrator can begin SW, FW and HW development. This greatly improves the integration effort as a vendor is up and running a RAID application (with the correct HW and FW) without the requirement for any enclosure modifications. If duplex operation is desired, the user simply needs to remove 2 disk drives from the enclosure and insert 2 RAID assemblies in their place. 1
