The impact is even greater than that.  Consider a system with several zones.  Each zone connects to storage of different types with different levels of reliability.  Perhaps you have a production zone and a development zone and a sandbox zone with dopey storage.

If you lose access to the dopey storage, not only do you drop your sandbox zone, you panic the entire server--with whatever implications that may carry for the other pools or services on the server.
