Factory-Default Disk Volume Locations
Fibre Channel disk modules connect to Fibre Channel ServerNet adapters (FCSAs) via
Fiber Channel arbitrated loop cables. This drawing shows the two Fibre Channel
arbitrated loops implemented within the Fibre Channel disk module.
For more information on the Fibre Channel disk module, see Fibre Channel Disk
Module on page 5-20.
Factory-Default Disk Volume Locations
This illustration shows the factory-default locations for the primary and mirror system
disk volumes where they reside in separate Fibre Channel disk modules:
FCSA location and cable connections vary according to the various controller and
Fibre Channel disk module combinations.
Fibre Channel Device Configurations
Storage subsystems in NonStop S-series systems used a fixed hardware layout. Each
enclosure can have up to four controllers for storage devices and up to 16 internal disk
drives. The controllers and disk drives always have a fixed logical location with
standardized location IDs of group-module-slot. Only the group number changes as
determined by the enclosure position in the ServerNet topology.
However, the modular Integrity NonStop NS-series systems have no fixed boundaries
for the hardware layout. Up to 60 FCSA (or 120 ServerNet addressable controllers)
and 240 Fibre Channel disk enclosures are possible, with identification depending on
the ServerNet connection of the IOAM and slot housing in the FCSAs.
