Storage Logical
Partition (SLPR)
NOTE:
The SLPR component is applicable only for the XP disk arrays. It does not exist
in the P9000 disk arrays. As a result, the SLPR-related data is not displayed in
P9000 Performance Advisor for the P9000 disk arrays.
The SLPR is a partition of the RAID500 to which the host ports (1 or more) and
the CLPRs (1 or more) are assigned. The SLPR0 will always exist (cannot be
deleted). Sometimes, the SLPR acronym includes an additional word. For example,
Storage administrator Logical Partition or Storage management Logical Partition,
both mean the same. The purpose of the SLPR is to allow multiple administrators
to manage a subsystem without the risk of causing mistakes that can destroy
another user's volumes, or reduce other user's expected performance by using
more components (e.g. cache) than required.
Thin Provisioning
(ThP, TP)
Using the thin provisioning, you can operate with a global pool of LDEVs that
are not assigned to a physical storage. The XP and the P9000 disk arrays add
virtual capacity from the pool of LDEVs as and when the data is written, and
only at that time is the physical capacity assigned to the LDEVs and used for
storage purpose.
WWN World Wide Name. A unique identifier assigned to a Fibre Channel device.
World Wide Name
(WWN) Group
The world wide name group provides access for every host in the specified
WWN group to a specified logical unit or group of units. This is part of the LUN
Security feature.
