Got a new LAN Free client, nothing out of the ordinary, but LAN Free perf
is slower than I'd hope.

I'm going to a ProtecTier VTL and have 20 sessions going.

Not started doing any fault finding yet, but the one big difference with
this client is that the tape HBA's are virtual ones (NPIV).

Has anyone seen less than stellar performance with this kind of setup, or
should the virtual HBA's be lower down the list of things to check?

For info, the VIO's do have seperate real HBA's for tape & disk.

Thoughts/comments welcome

Thanks

Steven
