Then, identify the remaining workloads that are considered appropriate for resource-sharing.
Next, define a balanced set of hardware resources that can be dedicated to any isolated
workloads, if required. Then, allocate the remaining DS8000 hardware for sharing among the
resource-sharing workloads. Carefully consider the appropriate resources and storage tiers
for Easy Tier and multi-tier extent pools in a balanced manner. Also, plan ahead for

where needed.
The next step is planning extent pools and assigning volumes and host connections to all
workloads in a way that is balanced and spread - ...
