5.3.2Input/Output (I/O) Module

The drive enclosure storage subsystem includes an enclosure with rear facing bays which house two (2) I/O modules (Figure 5–5).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 drive enclosure storage subsystem, providing external SAS cable interfacing with up to 60 SAS or SATA disk drives.
