xCAT (Extreme Cloud Administration Toolkit) is open-source distributed computing management software developed by IBM, used for the deployment and administration of Linux or AIX based clusters.


xCAT can:

  • create and manage diskless clusters
  • install and manage many Linux cluster machines (physical or virtual) in parallel
  • set up a high-performance computing software stack, including software for batch job submission, parallel libraries, and other software that is useful on a cluster
  • cloning and imaging Linux and Windows machines

xCAT has specific features designed to take advantage of IBM hardware including:

  • Remote Power Control
  • Remote POST/BIOS console
  • Serial over LAN functions
  • Hardware alerts and vitals provided via SNMP and email
  • Inventory and hardware management

xCAT achieved recognition in June 2008 for having been used with the IBM Roadrunner, which set a computing speed record at that time.[1][2]

xCAT is the default systems management tool of the IBM Intelligent Cluster solution.

xCAT is used by Lenovo.
