Enterprise Linux 5.7.  This release is important for our customers

  - Support for new hardware delivered in 2011, including Intel, AMD,
    POWER and IBM System z
  - Encompasses processors, chipsets and new drivers for storage,
    networking, and graphics

    a library and set of utilities. Allows security managers to verify
    security configuration and vulnerability status

    to improve centralized management of user filesystems in an
    enterprise environment

* High Availability Fencing
  - Fencing features to improve cluster reliability in Cisco UCS
