nimble:perfpol-name=PERF_POL_NAME

PERF_POL_NAME is the name of a performance policy which exists on the Nimble/Alletra 6k array and should be enabled for every volume in a volume type.

Note:

When upgrading to OpenStack deployment to Victoria or later, do unset nimble:multi-initiator extra-spec and set multiattach='<is> True'.

nimble:dedupe=true

Used to enable dedupe support for a volume-type.

nimble:iops-limit=IOPS_LIMIT

Used to set the IOPS_LIMIT between 256 and 4294967294 for all volumes created for this volume-type.

nimble:folder=FOLDER_NAME

FOLDER_NAME is the name of the folder which exists on the Nimble/Alletra 6k array and should be enabled for every volume in a volume type

These extra-specs can be enabled by using the following command:
