Hi Mark

UNOFFICIALLY, I'll tell you that combinations of FC HBAs from multiple
vendors, used in the same SAN, SEEMS to work just fine in our lab
environment.  BUT I wouldn't implement this unless the combinations you want
to use have been tested, and will be supported, by your vendors.  FC SANs
are just too new to expect solid interoperability; they just don't have the
miles under the wheels that, say, Ethernet does.  Please note that I'm NOT
saying the components don't work well; it's just that, in some increasingly
isolated cases, components from different vendors may not work well
together.

Hope this helps.

Terry, the information you provided in this email is really useful.
Can I ask one further question?  In Chris's environment he has mentioned
that he has a range of Operatring Systems.
What would your opinion be on the use of FC-HBA cards that are different
models within the SAN.
I.E.  Emulex in Solaris, Qlogic in Windows
All cards are going to a Brocade Switch.

Regards,  Mark
