Skytap on Azure + Precisely for High Availability Scenarios

For hot migrations, Skytap partners with Precisely, the market leader for high availability scenarios. Precisely supports IBM i and AIX. How Precisely supports the Skytap on Azure hot migration for IBM i is depicted below.

What is Precisely for IBM iSeries?

  • Precisely’s MIMIX is the most prevalent tool used in RPO scenarios of near-zero
  • Easy to Package – Support for both AIX and IBM i
  • Automated Role Swaps Allow for Testing, Operations Upgrades in Prod
  • AIX Solution Provides Live Snapshot Capability for Any Subsidiary Environment Seeding

This is built on IBM’s remote journaling which replicates changed data in real-time and minimizes bandwidth usage. The MIMIX change data capture replicates non-journaled data. This solution is flexible and platform independent because it supports mixed hardware, storage and IBM i OS version. It is also optimized for performance because it:

  • delivers near-zero RPO (zero with synchronous Remote Journaling)

  • provides near-zero RTO by maintaining a hot, switch-ready back up

  • includes performance tuning features to optimize performance for your environment (i.e. parallel applies and database caching)

  • has active-active replication with built-in conflict resolution that delivers RTO in seconds (as quickly as moving users to another active server)

The following outlines popular Precisely migration scenarios available for you to consider:

What’s different about AIX?

  • The AIX Mimix Product focuses on Volume Group replication and sync
  • Any applications encapsulated in the Volume Group are included as part of the replication
  • The Root Volume Group is NOT Replicated (Needs to be Handled Separately) [There are some known scripts for handling initial sync of Root Volume Group]
  • Point in Time Snapshot of Volume Groups
  • Inline Encryption
