NonStop NS14000 Series Planning Guide (H06.13+)

Fibre Channel Port to Fibre Channel Disk Modules
Fibre Channel disk modules (FCDMs) can be connected directly to the Fibre Channel ports on a
VIO enclosure, with these exceptions:
• Only configurations with two VIO enclosures are supported.
• A maximum of eight FCDMs (or up to eight daisy-chained configurations with each daisy-chain
configuration containing 4 FCDMs) can be connected in the NonStop NS14000 series system.
See “Example Configurations of the VIO Enclosures and Fibre Channel Disk Modules” (page 76).
Fibre Channel Port to Tape Devices
Fibre Channel tape devices can be connected directly to the Fibre Channel port on a VIO 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.
VIO Enclosure and Disk Storage Considerations
These considerations apply to a NonStop NS14000 series system:
• Only configurations with two VIO enclosures are supported.
• The group number for the VIO enclosures is 100.
• NonStop S-series I/O enclosures are not supported.
• A maximum of eight FCDMs can be connected in the NonStop NS14000 series system because
only two VIO enclosures are supported.
• Two Ethernet connections, one in each VIO enclosure module, that connect to the maintenance
entity are necessary to enable the OSM Service Connection and OSM Notification Director.
Fibre Channel Devices
This subsection includes:
• “Factory-Default Disk Volume Locations” (page 74)
• “Configurations for Fibre Channel Devices” (page 74)
• “Configuration Restrictions for Fibre Channel Devices” (page 75)
• “Recommendations for Fibre Channel Device Configurations” (page 75)
• “Example Configurations of the VIO Enclosures and Fibre Channel Disk Modules” (page 76)
The only Fibre Channel device used internally with NonStop NS14000 series systems is the Fibre
Channel disk module (FCDM). An FCDM and its disk drives are controlled through the Fibre Channel
ports located on the VIO enclosures. For more information on the Fibre Channel ports, see “Versatile
I/O (VIO) Enclosure” (page 22). For more information on the Fibre Channel disk module (FCDM),
see “Fibre Channel Disk Module (FCDM)” (page 24). For examples of cable connections between
Fibre Channel ports on the VIO enclosures and FCDMs, see “Example Configurations of the VIO
Enclosures and Fibre Channel Disk Modules” (page 76).
