1.3.3 Loop Resiliency Circuit Input/Output Module (FC-AL)
The Galaxy 65 storage Subsystem includes an enclosure with rear facing bays which house two Loop
Resiliency Circuit (LRC) I/O modules with integrated Rorke Data
Galaxy 65 RAID controller, known as
Storage Managers (SM) modules. (see Figure 1–3)
The FC-AL Backplane incorporates two independent loops formed by Port Bypass Circuits within the LRC
I/O modules.
The plug-in SM modules have been designed for integration into a Galaxy 65 storage Subsystem, utilizing
FCAL interfacing with the host computer system.
Processors housed on the LRC modules provide enclosure management and interface to devices on the
Backplane, PSU, LRC and Ops Panel, to monitor internal functions. These processors operate in a
master slave configuration to allow failover.
The module incorporates the following LED indicators, shown in Figure 1–7:
• Host Port 0 Signal Good (Green)
• Host Port 1 Signal Good (Green)
• Expansion Port 0 Rx Good (Green)
