In a practical sense if a fiber channel card fails on a server, you'd probably want to fail over the cluster to the second node until you resolved the issue. Redundant HBAs require multipath software for the server to properly load balance or fail over the disk IO. If you are considering this level of availability it really comes down to a very limited number of companies, EMC, HP/Compaq or IBM in the PC world. There are many workgroup solutions available, but with workgroup solutions, come workgroup support. > -----Original Message----- > From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd- > questions@freebsd.org] On Behalf Of Danny Howard > Sent: September 21, 2005 2:13 PM > To: freebsd-questions@freebsd.org > Cc: freebsd-scsi@freebsd.org > Subject: Reccomendations for FC-attached storage appliance? > > [NOTE: cross-posting to freebsd-scsi and -questions ... please reply > direct to me, or followup to just ONE list.
