Added support for QoS in the Fujitsu driver. The supported qos specs are: * maxBWS * read_bytes_sec * write_bytes_sec * total_bytes_sec * read_iops_sec * write_iops_sec * total_iops_sec Change-Id: I0f12c90f9483393501cf5788b66f724d47e72c8e

Fujitsu ETERNUS DX driver: Added support for QoS
|
|
|
|
What QoS settings are available depends upon the storage firmware version
|
|
of the ETERNUS AF/DX.
|
|
|
|
* When the storage firmware version is less than V11L30-0000,
|
|
only the upper limit of bandwidth(BWS) can be set using:
|
|
|
|
- ``maxBWS``
|
|
|
|
Note that when the firmware version of the ETERNUS AF/DX is earlier
|
|
than V11L30, upper limits for the volume QoS settings of
|
|
the ETERNUS AF/DX are set using predefined options. This means that
|
|
you should set the upper limit *of the ETERNUS AF/DX side* to a maximum
|
|
value that does not exceed the specified ``maxBWS``.
|
|
|
|
* When the storage firmware version is greater than V11L30-0000,
|
|
the IOPS/Throughput of Total/Read/Write for the volume can be set
|
|
separately using:
|
|
|
|
- ``read_bytes_sec``
|
|
- ``write_bytes_sec``
|
|
- ``total_bytes_sec``
|
|
- ``read_iops_sec``
|
|
- ``write_iops_sec``
|
|
- ``total_iops_sec``
|
|
|
|
