You install a filer cluster with two nodes. Then there is no single point of failure. I've done exactly that at customers of my company, i.e. set up NetApp filer clusters. Any disk can fail, any shelf can fail, any filer head can fail. A complete filer can fail. A switch can fail. The system will keep running and doing its job. And yes, we've tested all of that. Whether filers solve your problems is a different thing. I just pointed out the answer to the question "what if the filer breaks?". I'm not a NetApp salesman. ;-) Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
