I may be getting some new HBAs to put into my master servers.  They 
would be dual port cards.  Presently, my tape devices are on an older 
JNI HBA which requires me to reboot the server (Sun E450) to add 
devices.  As an additional bonus, the new HBAs would be 2Gb with the old 
ones 1Gb.  I'm considering moving the tapes to the new HBA.  However, 
the main reason we are going to get the HBAs is to attach to our 
enterprise SAN for disk storage.

Now, to get to my point, I'm aware that it's usually considered bad form 
to put tape and disk on the same port of an HBA.  What about tape and 
disk on different ports of the same HBA?  I would guess that if the card 
has sufficient bandwidth and the ports are truly independent of each 
other (not sharing any settings) that this configuration would be OK.

Any thoughts?
