HPSS Static Configuration Variables. Table 2-7 defines the HPSS static configuration variables,
which have more of a static nature in that they are not particularly relevant to how large the HPSS
system will be. They relate more to how many HPSS servers, storage classes, etc. will be defined
and therefore are not significant in the overall metadata size projection.

HPSS Installation Guide
Release 4.5, Revision 2
Description
The maximum total number of disk physical volumes.
The total number of disk virtual volumes that will be created, which is equal to the
number of disk physical volumes divided by the average disk stripe width.
This is the total number of Physical Volumes that will be managed by this subsystem.
The total number of tape virtual volumes that will be created, which is equal to the total
number of all PVR cartridges divided by the average tape stripe width.
Table 2-7 HPSS Static Configuration Values
Description
The number of subsystems controlled by this HPSS instance.
The maximum number of storage classes that will be defined.
The maximum number of storage hierarchies that will be defined.
The maximum number of file families that will be defined.
The maximum number of classes of service that will be defined, which typically will
equal the total number of storage hierarchies created.
The total number of tape drives used by HPSS.
The overall number of HPSS servers that will be defined. This includes the Name
Server, BFS, Storage Servers, Log Daemon, Log Clients, Startup Daemons, Movers,
etc.
The total number of BFS servers that will be configured. This value should be equal to
the number of subsystems.
This defines the total number of DMAP Gateway Servers that will be defined in the
system.
The total number of Name Servers that will be created. This value should be equal to
the number of subsystems.
