The StorageScaler 6000 storage subsystem includes an enclosure with rear facing bays which house
two (2) I/O modules (

). Processors housed on the I/O modules provide enclosure
management and interface to devices on the Backplane, PCM, and Display Panel in order to monitor
internal functions. The plug-in I/O modules have been designed for integration into a StorageScaler 6000
storage subsystem, providing external SAS cable interfacing with up to 60 SAS or SATA disk drives.
