hi Denis if you ask for my opinion i do not recomend lanfree backups, why thats spimle when you do a restore it dosn?t matter if your using san or not youre restore data always goes trough the lan. and that?s bad, then you have lost 75% of your reason to have lanfree backups, because what is here that relay matters. It is your restore time, and that will stay exacly the same.
This bug will not be fixed until TSM V 5.1 comes out.

Hello, We are currently evaluating the implementation of lanfree backups in our environment. I understand the conceptual benefits of sending data across the SAN vs. the LAN/WAN but am concerned with compatibility issues with our IBM TSM Environment and EMC Connectrix Environment. Has anybody implemented LANFREE in a similar environment? Can anybody give some example or insight to real life advantages to implementing LANFREE backups? Are there any tape drive contention issues when a drive gets allocated to a 'LANFREE' backup? How does TSM manage 'LANFREE' tapes? Does it dedicate a tape to a client (like collocation) or will other clients have access to write data to the same volser? How about attaching a 3590 FC-AL to a EMC Connectrix Fabric? Any other tips would be greatly appreciated.
