FCSA to Fibre Channel Disk Modules
FCSA to Fibre Channel Disk Modules
Fibre Channel disk modules (FCDMs) can be connected directly to FCSAs in an IOAM
enclosure (see Blade Elements to IOAM Enclosure
on page 6-6), with these
exceptions:
•
Only configurations with one IOAM enclosure are supported.
•
A maximum of 16 FCDMs can be connected in the Integrity NonStop NS1000
system because only one IOAM enclosure containing a maximum of four FCSAs is
supported.
See Example Configurations of the IOAM Enclosure and Fibre Channel Disk Module
on page 6-14
FCSA to Tape Devices
Fibre Channel tape devices can be connected directly to an FCSA in an IOAM
enclosure. With a Fibre Channel tape drive connected to a server, you can use the
BACKUP and RESTORE utilities to save data to and restore data from tape.
IOAM Enclosure and Disk Storage
Considerations
These considerations apply to an Integrity NonStop NS1000 system:
•
Only configurations with one IOAM enclosure are supported.
•
The group number for the IOAM enclosure is 100.
•
A maximum of 16 FCDMs can be connected in the Integrity NonStop NS14000
system because only one IOAM enclosure containing a maximum of four FCSAs is
supported.
•
Two or four FCSAs are split between only two IOAM modules, so loss of one
module takes down all primary or mirror Fibre Channel loops. See
Recommendations for Fibre Channel Device Configuration
on page 6-13.
•
Two G4SAs, one G4SA in each IOAM module, that connect to the ME are
necessary to enable the OSM Service Connection and OSM Notification Director.
Note. Connections to SCSI tape drives through a Fibre channel to SCSI router (model
M8201R) is not supported on Integrity NonStop NS1000 systems.
