Project eLiza  eLiza is a major initiative to deliver systems that manage themselves. Building upon today's eServer self- managing leadership, which is the foundations for eLiza, the objective is to give customers the power to manage environments that are hundreds of times more complex and more broadly distributed than exist today. Self Diagnosing / Optimising  Determines the cause of an error as it happens and avoids the lengthy service times trying to recreate errors after the fact.  Lightpath Diagnostics allow for fast problem determination, by pinpointing the exact cause, or potential cause of a problem  Integrated Systems Management Processor constantly monitors the health and critical subsystems of the server, and can alert you of impending issues Self Healing  Chipkill, Redundant bit steering, ECC caches, system redundancies eliminate unnecessary service calls Self Configuring / Protecting  Auto Partitioning allowing a partitioned system to re-partition itself, in the event of a node failure, and bring the remaining nodes back online. Eliminates a failed subsystem from keeping the whole "system" unavailable. Many eLiza Capabilities Architected into EXA
