How do you implement highly available computing? One extremely effective method is the use of clusters—networked groups of individual computers. HP's enterprise clusters are loosely coupled host systems—servers running HP-UX, Linux, or Windows—that are especially tailored for HA.
This chapter shows how you can create an HA cluster by configuring redundant groups of highly reliable hardware and software components together with HA software in such a way as to eliminate single points of failure. In addition, the chapter discusses single-system HA in both clustered and non-clustered solutions.
Here is what will be covered:
• Identifying Single Points of Failure
• Eliminating Power Sources as Single Points of Failure
