View and Edit Host-Side Parameters
Fibre Connection Options:
Use the › fl keys to scroll down to “View and Edit Configuration
Parameters,” "Host-side SCSI Parameters," and then "Fibre
Connection Option." A prompt will display all the options. Select
one appropriate for your Fibre channel topology. If connection to host
is through a Fibre hub, choose "Loop only." If connection to host is
through a Fibre switch or directly to a server, choose "Point to point
only." Proper selection is necessary and will decrease overhead on
data transmission.
View and Edit Drive-Side Parameters
Connecting Drives with Fibre Channel Dual Loop:
Fibre drives are usually configured in a JBOD enclosure. Through the
enclosure backplane, these drives form a circuit loop and the external
connectors are provided as A port and B port. You may choose to
assemble certain number of disk drives into a dual-loop configuration
using two controller channels. To configure a dual-loop, you may
connect one drive channel to the A port and another to the B port of
drive enclosure (JBOD). The dual-loop configuration not only doubles
traffic bandwidth by separating the transmitting and receiving paths
but also provides path redundancy. Read/Write will be continued
should one channel fail.
