2. Optional. Order the z-synergy Services license to support the physical capacity
of all ranks that are formatted as CKD.
3.
Optional. Order the Copy Services license to support the total usable capacity
of all volumes that are involved in one or more copy services functions.
Note: The Copy Services license is based on the usable capacity of volumes
and not on physical capacity. If overprovisioning is used on the DS8880 with a
significant amount of Copy Services functionality, then the Copy Services
license needs only to be equal to the total rank usable capacity (even if the
logical volume capacity of volumes in Copy Services is greater). For example, if
the total rank usable capacity of a DS8880 is 100 TB but there are 200 TB of thin
provisioning volumes in Metro Mirror, then only a 100 TB of Copy Services
license is needed.
4.
Optional. Order the Copy Services Manager on the Hardware Management
Console license that support the total usable capacity of all volumes that are
involved in one or more copy services functions.
Rules for ordering licensed functions
A Base Function license is required for every base frame. All other licensed
functions are optional and must have a capacity that is equal to or less than the
Base Function license.
For all licensed functions, you can combine feature codes to order the exact
capacity that you need. For example, if you require 160 TB of Base Function license
capacity, order 10 of feature code 8151 (10 TB each up to 100 TB capacity) and 4 of
feature code 8152 (15 TB each, for an extra 60 TB).
When you calculate usable capacity for the Copy Services license, use the size of
each volume involved in a copy services relationship and multiply by the size of
each extent.
When you calculate physical capacity, consider the capacity across the entire
storage system, including the base frame and any expansion frames. To calculate
the physical capacity, use the following table to determine the total size of each
regular drive feature in your storage system, and then add all the values.
