Reallocation of storage to preserve the capabilities of a volume.
ISP is capable of understanding Storage Area Network (SAN) topology and of
efficiently using the available intelligent storage.
ISP interacts with other Veritas components, where these are available, such as
the Veritas Array Integration Layer (VAIL) and the SAN Access Layer (SAL), to
take appropriate actions when configuring intelligent storage in a SAN
environment.
See About ISP and the SAN Access Layer on page 233.
Products and features such as dynamic multipathing (DMP), mirroring, RAID-5,
SAL, snapshots, VAIL and Veritas Volume Replicator (VVR) require licenses in
addition to the base license.
This book describes the command-line interface to ISP, and the language that is
used for writing new rules, capabilities and templates. For a description of the
graphical interface to ISP that is provided by the Veritas Enterprise Administrator
(VEA), see the Veritas Enterprise Administrator Users Guide and VEA online help.
For more information about how you can apply ISP in different scenarios such as
implementing storage tiers, offhost processing, or remote mirroring between
different locations, see the Veritas Storage Foundation Intelligent Storage
Provisioning Solutions Guide.
The benefits of ISP
When creating a volume in Veritas Volume Manager in previous releases, you
could specify the disk storage on which to lay out its various parts, subdisks,
plexes, and so on. In specifying the storage to be used, you had to take into account
the tolerance of a volume to failure of any component of the storage infrastructure,
and how the specified layout affected I/O performance and reliability of service.
For small installations with a few tens of disks in relatively low-specification
arrays, you could either specify the storage layout manually to commands such
as vxassist, or rely on vxassist to choose appropriate storage based on general
layout specification, such as mirror across controllers and mirror across
