they share storage, the type of I/O requests made by applications, and the
amount of I/O from/to each volume. For example, allocating two volumes to
a single disk array that has a large cache would probably provide better overall
I/O performance than placing one volume on the disk array and the other on
a JBOD. If necessary, you can configure smaller storage pools in separate disk
groups to restrict the allocation of storage. Alternatively, you can explicitly
specify the storage that can or cannot be allocated to a volume.
Administration roles in ISP
The administration of ISP can seem overwhelming when compared with the
traditional administration model in Veritas Volume Manager.
To simplify matters, it is useful to think in terms of the following levels of
administration based on level of knowledge of ISP, and frequency of application
of this knowledge:
■ Basic administration tasks
■ Advanced administration tasks
■ Expert administration tasks
Basic administration tasks are performed most often and require the least
knowledge of ISP to perform. Expert storage administration tasks are performed
least often and require the most knowledge of ISP to perform.
Basic administration tasks
Basic administration tasks include creating storage pools, and creating and
administering volumes. This includes performing tasks such as adding or removing
mirrors or columns from volumes, resizing volumes, and creating and using
volume snapshots.
The system administrator’s role requires the following knowledge of ISP:
■ Familiarity with the meaning of the terms disk group, storage pool, template,
user template, application volume, and capabilities such as reliability,
performance and fault tolerance.
■ What templates and user templates are available for use in creating volumes
with the required capabilities.
■ What templates and user templates are associated with the disk groups in
which you will create volumes.
■ How to use the VEA or the vxassist and vxvoladm commands to perform your
tasks.
