XP arrays monitored by XP Performance Advisor
Each XP array can be identified by its DKC or model number. If user-friendly name is provided for
the XP array, it appears in brackets beside the DKC number. The resources in an XP array are logically
grouped under the following main categories:
DescriptionXP array main categories – Resource selection
tree
Comprises of frontend resources, like CHAs and the
associated MPs and ports. For more information, see
“Front-end navigation path” on page 221.
Front-end
Comprises of individual CLPRs. For more information,
see “Cache navigation path” on page 223.
Cache
Comprises of backend resources, like DKA pairs and
their MPs, and RAID groups. RAID groups further
comprises of the associated physical LDEVs and pool
LDEVs (LDEVs assigned to a ThP or Snapshot pool). For
more information, see “Back-end navigation
path” on page 224.
Back-end
Comprises of individual ThP pool IDs, and the
associated RAID groups and VVols. The RAID groups
further display the list of associated physical LDEVs.
The ThP pools are displayed only for XP24000. If the
selected XP array is not of type XP24000, the ThP Pool
is not displayed for that XP array. For more information,
see “ThP Pool navigation path” on page 227.
ThP Pool
Comprises of individual Snapshot pool IDs, and the
associated RAID groups and VVols (P–Vols and S–Vols).
The RAID groups further display the list of associated
physical LDEVs. The Snapshot pools are displayed for
XP24000, XP20000, XP12000, XP10000, and
SVS200 array types. If the selected XP array does not
belong to one of the above mentioned array types, the
Snapshot Pool is not displayed for that XP array. For
more information, see “Snapshot Pool navigation
path” on page 229.
Snapshot Pool
Comprises of volumes that are used in Business Copy
or Continuous Access transactions. The Business Copy
volumes comprises of individual physical LDEVs, and
the Continuous Access volumes comprises of Journal
pool IDs that have LDEVs configured to be part of the
Journal pools. Continuous Access volumes can be
configured on XP24000, XP12000, XP10000,
SVS200, XP20000, and SVS400 type arrays. For
more information, see “Replication Volumes navigation
path” on page 231.
Replication Volumes
