The new offerings are part of HP's drive to provide middleware stacks based on both open source software and commercial software, HP executives said. "We take a very holistic view of the solutions stack so it is much deeper than just saying Red Hat or Novell is certified on all our platforms here at HP," said Jeffrey Wade, worldwide Linux marketing manager for HP. "It is really about looking at manageability, high availability and backup and the middleware solutions people may want to use on top of all of this."
