Ops Center Administrator incorporates best practices to calculate the best pool sizes based on the media available in the storage system. When using the basic pool creation option, pool size is determined as follows:
- Ops Center Administrator identifies all the parity groups of the same disk type, disk capacity, disk speed, RAID type and layout and determines the available capacity of the usable LDEVs. Only parity groups in the Available and Quick Formatting states are eligible for creating pools using the basic method.
- Ops Center Administrator then uses combinations of these parity groups where four or more parity groups of the Bronze, Silver, or Gold tiers can be added together, or there is a parity group of the Platinum or Diamond tier, to compute various possible pool sizes that can be created for the combination of disk type, disk capacity, disk speed, RAID type and layout. Note: If your parity groups do not meet these requirements, you must use the advanced method of pool creation.
- Based on the Storage System model, Ops Center Administrator determines the maximum pool size.
- Ops Center Administrator then displays the pools in increasing order of pool size.
