This table lists the FCSA group-module-slot-port (GMSP) and disk group-module-shelf-bay
(GMSB) identification for the factory-default system disk locations in the configuration of four
FCSAs, four Fibre Channel disk modules, and two IOAM enclosures:

Daisy-Chain Configurations
When planning for possible use of daisy-chained disks, consider:
Requirements for Daisy-Chain
1
Daisy-Chained Disks Not
Recommended
Daisy-Chained Disks Recommended
All daisy-chained Fibre Channel disk
modules reside in the same cabinet and
are physically grouped together.
Many volumes in a large Fibre
Channel loop. The more volumes that
exist in a larger loop, the higher the
potential for negative impact from a
failure that takes down a Fibre
Channel loop.
Cost-sensitive storage and
applications using low-bandwidth
disk I/O.
ID expander harness with terminators
is installed for proper Fibre Channel
disk module and drive identification.
Applications with a highly mixed
workload, such as transaction data
bases or applications with high disk
I/O.
Low-cost, high-capacity data storage
is important.
