We can manage this as we have high availability and redundancy, but without that it could be a real problem. The level of customer support needs to be improved. There is currently an issue with Lenovo switching out SAN switches from the chassis, which will cause problems for people who already have a set up with the SAN switch connected to the central storage. This could require an entirely different network, adding an additional cost for the user.
