case, the performance and protection characteristics of the virtual pool would determine
that it provides high performance storage. Hence, when giving a name to the virtual pool,
you might choose "gold" or "tier1" to indicate that the storage provides the highest
performance.
When a provisioning user requests the creation of a block volume from the "gold" virtual
pool, ViPR chooses the physical array/physical storage pool combination on which the
volume will be created. The virtual pool can comprise physical pools spanning a number
of arrays, so the actual array chosen could be any of them. The provisioning user does not
care which physical pool is chosen, only that it provides the level of performance
consistent with "gold" storage.
Automatic and manual virtual pools
When creating or editing a virtual pool, the UI helps you choose the physical pools that
match the performance and protection criteria that you are looking for by providing a set
of criteria and listing the pools that match the criteria. The storage pools table list all of
pools that are currently available that match the criteria and is dynamically updated as
you make criteria selections.
If you set the pool to be a "manual" pool, you can select the storage pools that will
comprise the pool. These storage pools will be fixed unless you edit the virtual pool.
If you select "automatic", the storage pools that comprise the virtual pools will be
automatically updated during the virtual pool's lifetime based on the availability of
storage pools in the virtual array.
An automatic virtual pool will be updated under the following circumstances:
u
During discovery of a storage system.
u
When a virtual pool is updated and saved (once a pool has associated assets only
protection criteria can be updated).
u
When a storage system, storage pool or port is registered or deregistered.
u
When the storage ports for a network are updated.
u
When the storage pools in a virtual array are updated.
u
When a network is assigned to a virtual array.
Creating or editing a virtual pool for block storage type
Create a virtual pool for block by specifying the criteria that physical storage pools must
match.
Before you begin
u
This operation requires the System Administrator role in ViPR.
u
When determining the minimum number of paths, maximum number of paths, and
paths per initiator:
l
The values must match the configuration and limitations of the physical
infrastructure.
l
There must be enough physical paths available to meet the criteria of the virtual
pool.
Procedure
1. Select Admin > Virtual Assets > Virtual Pools.
2. Click Add or select an existing virtual pool name to edit.
3. Name and describe the pool.
