This is about DM multipath, not about SDD multipath, so I couldn't care less about what big blue supports there ;-)

I have heard the same from all the different vendors...

But seriously, can you point me at those discussions? Are there any real

seems to help quite a bit for me; w/o, failover times are inacceptable.

It does help for us too, however most recently i saw this discussed on the dm-devel list... Search for qlogic.
