iTERA HA

Data resiliency and rapid recovery that delivers:

• Remarkable ease of use

• Surprising affordability

• Proven reliability

Proven to be the most efficient, most reliable System i replication engine, the architecture for iTera HA 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 iTera HA, an extremely efficient process harvests data from journal receivers and applies it to objects.

Today, Vision is taking object self-healing to a whole new level with its breakthrough Concurrent Audit Concurrent Heal (CACH) 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 Vision leading the way in HA innovation and reliability.

Extensive autonomic functions mean less time to manage
• Autonomic processes makeiTera HA easy and fast to manage—typically 15 to 20 minutes per day
• Exclusive CACH technology automatically discovers out of sync objects and "heals" them at the record level
• Journal components are automatically monitored and recreated when needed
• Self-managing functions ensure smooth switchovers and allow iTera HA to be quickly installed with users trained in days, not weeks

Reliably mirrors all system-critical objects
• Programs, data areas, data queues, IFS, user profiles, device configurations, spool files, triggers, constraints, WebSphere MQ, and more are replicated in real-time

Reliable, simple-to-use switchover and failover
• Since objects stay in sync, and latency is rare, switchover/failover is more reliable
• Switchover process is automated, ensuring a faster, less error-prone process

Scalable
• iTera HA scales easily to any size and type of replication environment
• Individual features are easily enabled/disabled

Fast, easy installation
• Its installed and configured—with mirroring started—in a few hours
• When installed on the production system, iTera HA automatically installs on the backup
• No need to save/restore objects—most mirrored objects sync quickly via network

Robust IFS replication capabilities
• iTera HA replicates IFS both on an object and a record level
• Integrated, simple-to-use IFS auditing and monitoring functions
• Efficiently replicates large IFS and DLO objects, as well as high transaction volumes

iTera HA is remarkably efficient, reliable, easy-to-use, and affordable, which is why it's become the fastest selling high availability solution in the iSeries world. Since 2000, iTera HA has been installed at hundreds of locations worldwide, many of these installations are at companies that used another high availability product. So why would they abandon their previous HA investment and switch to iTera HA? Simple. Vision proves time and time again it can eliminate frustrations caused by other inefficient, unreliable, or high-cost HA products.

iTera HA Costs Less to Buy and Far Less to Own
iTera HA costs about the same as our competitor's scaled down "lite" and "express" offerings, but there is nothing "lite" about it. It's comprehensive, powerful, and full-featured, yet it costs significantly less than other full-featured HA products. Another huge cost benefit is the amount of money that iTera HA saves after it is purchased. For instance, since ours costs only a fraction of other full-featured products, you can save tens of thousands of dollars each year on annual maintenance fees. And because of significant automation and ease-of-use features, iTera HA rarely takes more than 15 to 20 minutes a day to manage. Compare this to the several hours a day required by many other high availability products.
