We recently moved to a multiple server site due to bug fixes at 10.2.2 concerning slowness with manager when using a network share for the config store and slow performance from caches on network shares. However, we have had issues with ArcGIS Server losing connection to our config store which we placed on a network NAS devices. Moving the store local to one of the servers in the site resolved the issue, but introduced a single point of failure, which unfortunately did happen to us when that server crashed. One note about the space is that it is used organization wide for storing all data. We are looking into moving it to a less used storage device. Thought I would see if anyone had any suggestions before we do so. I am afraid the same thing will happen and we will need to move it back to the server again.
