What are the effects of powering off a workstation on a DAS or SAS connection?
Depends. Let’s do SAS first, it is easier. If a SAS is connected to a concentrator, then the concentrator will bypass the SAS connection using an internal data path. If a DAS is connected to a concentrator, then the concentrator will also bypass the DAS. If a DAS is connected to the trunk rings without using an optical bypass switch, then the trunk ring will wrap. If multiple stations power off on the trunk rings, then the ring will be segmented. Now if a DAS is using an optical bypass switch, the switch will kick in and prevent the ring from wrapping.
