Key tools

• cfengine
• Flexible tool, has some scaling questions (but,
  someone claimed it can scale)
• SystemImager/LUI
• Neither does it all. They are both being revised
  in OSCAR.
• NFS - only scales when not used hard.

Other tools

• Chiba City system management appears to be well
  thought out. Proof will be when another large
  cluster can use them.
• Bigger problem - variance in cluster management
  hardware can make using other cluster's tools
  difficult.
• Biggest problem - management philosphies are
  different, and sometimes don't meet.

Key points

• Remote power and consoles are essential both are
  needed for large clusters.
• Modeling may only make sense if the app is well
  defined. Most modeling will be of the network.
• Many tools and methods available for software
  consistency.

5
Other points.

• Larger the cluster, the more essential remote
  power.
• Sometimes, remote consoles can overwhelm large
  clusters.
• Some tools available, but in some areas, little
  or no tools available.
• Few tools to model a cluster
