NonStop NS1000 Planning Guide (H06.08+)

Fibre Channel Ports to Tape Devices
Fibre Channel tape devices can be connected directly to the Fibre Channel ports 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
NOTE: For NonStop NS1000 servers that contain I/O Adapter Module (IOAM) enclosures,
refer to the H06.07 (or earlier) version of this manual for planning, configuration, and maintenance
information of the IOAM enclosure.
These considerations apply to an Integrity NonStop NS1000 system:
• Only configurations with two VIO enclosures are supported.
• The group number for the VIO enclosures is 100.
• Up to four FCDMs can be connected to the embedded Fibre Channel ports on a VIO enclosure
in the Integrity NonStop NS1000 system.
• Two or four Fibre Channel connections are split between only two VIO enclosure modules,
so loss of one module takes down all primary or mirror Fibre Channel loops. See
“Recommendations for Fibre Channel Device Configuration” (page 85).
• 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 describes Fibre Channel devices and covers these topics:
• “Factory-Default Locations for Disk Volumes” (page 84)
• “Configurations for Fibre Channel Devices” (page 84)
• “Configuration Restrictions for Fibre Channel Devices” (page 84)
• “Recommendations for Fibre Channel Device Configuration” (page 85)
• “Example Configurations of the VIO Enclosures and FCDMs” (page 85)
The only Fibre Channel device used internally with the Integrity NonStop NS1000 system 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 60). For more information on the Fibre Channel
disk module (FCDM), see “Fibre Channel Disk Module” (page 62). For examples of cable
connections between Fibre Channel ports on the VIO enclosures and FCDMs, see “Example
Configurations of the VIO Enclosures and FCDMs” (page 85).
