Yes i found that tsm lan-free 5.5 woks with gpfs. But in real model gpfs
wouldn't be used, that's why i looking for another ways.

Well, files not so small for transfering over TCP/IP, but consumer needs
fast access for recently migrated data. So he determined such conditions
and set task and I solve it.
Though decision of this problem interesting per se.
I've tested that SANergy works with TSM BA Client well (who would doubt :)
), but my chief dosen't sure that HSM will works also fine.
Do I correctly understand, that HSM uses TSM BA Client functions for
transfer migration data (all options for hsm declaring in clients
dsm.sys)?

You are aware that with TSM version 6.1 Lan-free is also formally
supported on GPFS? There was no code-change, just a formal support
statement, so you can get this to work with 5.5 as well....

As for HSM, I'd think that either requiests are so small that you
don't mind using TCP/IP or so large that you don't mind writing
directly to tape.
