I am building a large tape SAN. However, I think that trunking could cause performance problems with OOF issues. Do you have a opinion regarding tape SAN traffic and trunking?
Yup, no need to trunk to tape drives. The tape will become the bottleneck long before the link will. Just make sure you allocate tape resources either within a separate tape fabric or if within the disk fabric then avoid going across inter-switch links. Allocate tape on the same switch as the server resides and zone the tape HBA away from the disk ports.
