accessible to defined zone. For information on partitioning, configuring
FC I/O blade ports, channel zoning, and host mapping, see
Configuring
Your Library
on page 47.
Details about cabling FC I/O blades include:
• Each expansion module can support up to two FC I/O blades. A
maximum of four FC I/O blades can be present in any library
configuration. A maximum of four FC drives can be connected to one
FC I/O blade.
• Ports 1 and 2 on each FC I/O blade are reserved for connection to
hosts. Ports 1 and 2 are always in target mode. The other four ports
(3, 4, 5 and 6) are always in initiator mode. See
Figure 20
.
• SAN-ready tape drives that are shipped with FC I/O blades include
24-inch, orange fibre optic cables to connect drives to initiator ports
on an I/O blade.
• Ideally, an installed tape drive should be cabled to a port on the
nearest FC I/O blade to eliminate the need to manage excessively
long cables. The nearest FC I/O blade is usually located in the same
expansion module as the tape drive.
Note:
