Proven to be the most efficient, most reliable iSeries replication engine, architecture for Echo² was built from the start using IBM's remote journaling technology. This eliminates user/log spaces, vulnerabilities, and extra CPU cycles. Native remote journaling eliminates the need for a multi-thread data apply process. With Echo², an extremely efficient process harvests data from journal receivers and applies it to objects.

Today, iTera is taking object self-healing to a whole new level with its breakthrough Concurrent Audit Concurrent Heal Echo² (CACHe2) technology. This remarkable patent-pending process discovers and corrects data integrity problems in real-time at the record-level. This eliminates the need to resynchronize entire objects when an out-of-synchronization condition is detected, which significantly speeds the correction of data integrity problems and reduces bandwidth traffic between mirrored environments as well as disk I/O. Automatic record-level monitoring and healing is yet another example of iTera leading the way in HA innovation and reliability.
