When to use Smart Tiers Z
Smart Tiers Z is the best fit in an environment in which Thin Provisioning Z is a good fit and datasets
with different performance requirements share volumes.
For detailed information, see “Configuring thin provisioning ” (page 54) .
Resource groups strategies
A storage system can connect to multiple hosts and be shared by multiple divisions in a company
or by multiple companies. Many storage administrators from different organizations can access
the storage system. Managing the entire storage system can become complex and difficult. Potential
problems are that private data might be accessed by other users, or a volume in one organization
might be destroyed by mistake by a storage administrator in another organization.
To avoid such problems, use Resource Partition to set up resource groups that allow you to manage
one storage system as multiple virtual private storage systems. The storage administrator in each
resource group can access only their assigned resources and cannot access other resources.
Configuring resource groups prevents the risk of data leakage or data destruction by another
storage administrator in another resource group.
The resources such as LDEVs, parity groups, external volumes or ports can be assigned to a resource
group. These resources can be combined to flexibly compose a virtual private storage system.
Resource groups should be planned and created before creating volumes. For more information,
see
“Configuring resource groups” (page 21) .
