10 Introduction to ISP
Basic concepts in ISP
Any traditional non-ISP volumes that you create in a disk group with a storage
pool remain outside the storage pool.
To create a storage pool within a disk group, use the
vxpool create command
and specify a storage pool definition that is appropriate for the kind of volumes
that you wish to create. This sets up the storage pool and installs the correct
templates in it. Alternatively, if you specify the
-o intent to the vxassist make
command to create an ISP volume, a storage pool is set up automatically for you
in the disk group.
The following table lists the standard pool definitions that are included in the
ISP configuration database.
Pool definition Description of supported volumes
any_volume_type Any template in the ISP configuration database.
mirror_stripe_volumes Distribution of I/O from and to volumes across
multiple columns within mirrors.
mirrored_prefab_raid5_volumes Multiple copies of data configured on
prefabricated RAID-5 disks that are exported by
an array.
mirrored_prefab_striped_volumes Multiple copies of data configured on
prefabricated striped disks that are exported by
an array.
mirrored_volumes Multiple copies of data.
prefab_mirrored_volumes Prefabricated data mirrors that are exported by
an array.
prefab_raid5_volumes Prefabricated RAID-5 disks that are exported by
an array.
prefab_striped_volumes Prefabricated striped disks that are exported by
an array.
raid5_volumes Use parity to maintain redundant data.
stripe_mirror_volumes Distribution of I/O from and to volumes across
multiple columns, where each column has
multiple copies of data.
striped_prefab_mirrored_volumes Distribution of I/O from and to volumes across
multiple columns that are configured on
prefabricated data mirrors exported by an array.
striped_volumes Distribution of I/O from and to volumes across
multiple columns.
