> 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.
