About FC-AL Host Adapters
The Sun Fire V890 server uses a Qlogic ISP2200A intelligent Fibre Channel processor
as its on-board FC-AL controller. Integrated into the system motherboard, the
ISP2200A resides on PCI Bus A and supports a 64-bit, 66-MHz PCI interface. The
on-board FC-AL controller controls FC-AL operations on Loop A of the base
backplane (and the upper backplane when the two are joined as an expanded array).
To take advantage of the dual-loop capability of the FC-AL backplanes, an optional
PCI FC-AL host adapter card is required to control the second loop (Loop B). For
this purpose, Sun offers the Sun StorEdge PCI Dual Fibre Channel Host Adapter
card (part number X6727A). This card provides two separate FC-AL channels, each
controlled by a Qlogic ISP2200A processor. Each channel provides an external port
for connection to external Fibre Channel devices. One of the channels also provides
an internal port for connection to the Loop B port on the base FC-AL disk backplane.
If the internal port is used, external Port 1 is unavailable for connection to external
devices.
