Hi everyone, Looks like we need to replace the RAID controller in our poweredge 2950. The unit currently has a PERC 5/I, which apparently has no audible alarm. I would like to upgrade to a controller that does in fact have an alarm, but I'm not sure which make or models to consider. Any info would be great, Al Puzzuoli Michigan State University Information Technologist http://www.rcpd.msu.edu Resource Center for Persons with Disabilities 517-884-1915 120 Bessey Hall East Lansing, MI 48824-1033
