Recommendations for Fibre Channel Device Configuration
These recommendations apply to FCSA and Fibre Channel disk module
configurations:
•
Primary Fibre Channel disk module connects to the FCSA F-SAC 1.
•
Mirror Fibre Channel disk module connects to the FCSA F-SAC 2.
•
FC-AL port A1 is the incoming port from an FCSA or from another Fibre Channel
disk module.
•
FC-AL port A2 is the outbound port to another Fibre Channel disk module.
•
FC-AL port B2 is the incoming port from an FCSA or from a Fibre Channel disk
module.
•
FC-AL port B1 is the outbound port to another Fibre Channel disk module
•
In a daisy-chain configuration, the ID expander harness determines the enclosure
number. Enclosure 1 is always at the bottom of the chain.
•
The group number for the IOAM enclosure is 100.
•
FCSAs can be installed in slots 3 through 5 in an IOAM.
•
G4SAs can be installed in slots 3 through 5 in an IOAM.
•
With primary and mirror Fibre Channel disk modules in the same cabinet, the
primary Fibre Channel disk module resides in a lower U than the mirror Fibre
Channel disk module.
•
Fibre Channel disk drives are configured with dual paths.
•
Where possible, FCSAs and Fibre Channel disk modules are configured with four
FCSAs and four Fibre Channel disk modules for maximum fault tolerance. If
FCSAs are not in groups of four, the remaining FCSAs and Fibre Channel disk
modules can be configured in other fault-tolerant configurations, such as with two
FCSAs and two Fibre Channel disk modules or four FCSAs and three Fibre
Channel disk modules.
•
The Integrity NonStop NS1000 supports only configurations with one IOAM
enclosure. In systems with one IOAM enclosure:
°
With two FCSAs and two Fibre Channel disk modules, the primary FCSA
resides in module 2 of the IOAM enclosure and the backup FCSA resides in
module 3. (See the example configuration in Two FCSAs, Two FCDMs, One
IOAM Enclosure on page 6-15.)
°
With four FCSAs and four Fibre Channel disk modules, FCSA 1 and FCSA 2
reside in module 2 of the IOAM enclosure and FCSA 3 and FCSA 4 reside in
module 3. (See the example configuration in Four FCSAs, Four FCDMs, One
IOAM Enclosure on page 6-16.)
