RIO-G interconnect separation
Each RIO-G loop is dedicated to a given storage image. All I/O enclosures on the
RIO-G loop with the associated host adapters and drive adapters are dedicated to
the storage image that owns the RIO-G loop.
As a result of the strict separation of the two images, the following configuration
options exist:
v Each storage image is assigned to one dedicated RIO-G loop; if an image is
offline, its RIO-G loop is not available.
v All I/O enclosures on a given RIO-G loop are dedicated to the image that owns
the RIO-G loop.
v Host adapter and device adapters on a given loop are dedicated to the
associated image that owns this RIO-G loop.
v Storage enclosures and storage devices behind a given device adapter pair are
dedicated to the image that owns the RIO-G loop.
v Configuring capacity to an image is managed through the placement of storage
enclosures on a specific DA pair that is dedicated to this image.
