  Yes, uniprocessor node.

  Yes, we do have a switched frame.

  No, the reason is that the end of our SP is in sight. Plus the fact that
  a 24 hour service for backup/archive/restore/retrieve/HSM much better
  can be guaranteed on a 'single' box. A big single box, that is.

  Eric van Loon and Sheelagh Treweek also did talk about H70.

  Older version.

  Richard, see my remarks above why moving from SP to F50/H70.

  That's something I'll keep in mind.

  No, all nodes (except SP node's) resides outside the SP (> 150).

  I'am not sure, I hope so.

  Again, thank all of you.
