The Benefits of ISP

How ISP Enhances Volume Management

Summary of the Benefits of Using ISP

The following list summarizes the main benefits that VERITAS ISP provides over the existing

storage allocation features in vxassist:

◆ Storage is automatically allocated based on abstract requirements such as the desired

capabilities of a volume.

◆ Prefabricated capabilities that are provided by vendor-specific features of intelligent storage

arrays can be encoded as storage attributes, and used to allocate storage.

◆ Volumes can be created or grown in batch mode safe in the knowledge that ISP will balance

the requirements of all volumes.

Application Volumes

User-specified rules

and capabilities

VxVM’s knowledge of storage

attributes is potentially

unlimited. You can define

additional attributes that are to

be used when selecting storage.

Application volumes with

the required capabilities are

built within the storage pool

according to pre-defined and

user-specified rules and

templates.

The vxvoladm command

uses the allocation engine to

select available storage from

the storage pool when

creating and administering

application volumes.
