"""Contains configuration options for NetApp drivers.
|
|
|
|
Common place to hold configuration options for all NetApp drivers.
|
|
Options need to be grouped into granular units to be able to be reused
|
|
by different modules and classes. This does not restrict declaring options in
|
|
individual modules. If options are not re usable then can be declared in
|
|
individual modules. It is recommended to Keep options at a single
|
|
place to ensure re usability and better management of configuration options.
