Sample ISP Deployments

This section contains high-level examples of how you can configure volume creation using ISP.

Using Storage Pool Policies

As described in Policy, a storage pool's policies affect how it allocates LUNs to create new volumes, and how it uses templates. By selecting which templates and LUNs are associated with a storage pool, and setting appropriate policies on the storage pool, you can control how storage is allocated to volumes. For example, a storage pool might be composed entirely of LUNs that have a hardware snapshot capability (for example, EMC Business Continuity Volumes). Setting the AutoGrow policy to pool ensures that the entire storage pool remains snapshot-capable as illustrated in Effect of Setting the Value of the AutoGrow Policy to pool.

If the AutoGrow policy level were to remain set to the default value of diskgroup, this would allow the ISP to aggregate LUNs from the disk group.

Effect of Setting Non-Default Storage Pool Policies illustrates how setting the AutoGrow policy to diskgroup allows LUNs from the same disk group that are outside the storage pool to be used, and setting the SelfSufficient policy to host allows templates that provide the required capabilities to be imported from outside the storage pool or disk group.
