Technical information

IBM United States Hardware Announcement 112-001 IBM is a registered trademark of International Business Machines Corporation

to the storage controller by creating two redundant paths from each storage

controller to each loop of the expansion units.

This feature requires the order of one additional 5-meter optical cable feature

(#2044) and one SFP GBIC feature (#2010 or #2011) on each expansion unit

(EXNx000) that will be directly attached to the storage controller.

Note: These are features of the EXN1000 and EXN4000. If dual-path FC cabling is

installed, every storage loop of the storage controller must be dual-path.

Feature number 9560 is a plant-only feature -- it may be specified when the N series

system is initially ordered. It may not be specified for an MES (field) order. Dual-

path FC cabling may be implemented on installed N series storage controllers via

an MES order of one each of feature #2010 or #2011, and any of the FC optical

cables (#2042, #2043, or #2044) for each expansion unit in the configuration that

is attached directly to the storage controller. The FC cables must be of sufficient

length.

Additional FC adapters may be required if additional ports are needed.
