MIMIX Availability: Business Continuity Solutions for IBM i

Protect the unprotected in your IBM i environment

Extend and enhance IBM® PowerHA® high availability

MIMIX for PowerHA works with IBM PowerHA to extend and enhance its data and application protection. IBM® PowerHA® SystemMirror® for i is based on the IBM storage subsystem's high availability features, which replicate at the disk sector level. IBM PowerHA adds intelligence to address the difficulties of using sector-based replication with the IBM i architecture. However, gaps may exist in IBM PowerHA protection, leaving data unreplicated and providing none of the safeguards that come with an additional local or remote HA/DR server.

MIMIX for PowerHA is a complementary solution that enhances IBM PowerHA protection and audits for conditions that could impact switch operations. When paired with MIMIX Availability, MIMIX for PowerHA extends HA/DR protection by enabling replication of data to additional local or remote servers for disaster recovery, query and data distribution purposes.

MIMIX for PowerHA replicates object types that are not supported by IBM PowerHA, as well as data associated with applications that have not been modified for IBM PowerHA. All data and applications are fully protected with the addition of MIMIX for PowerHA.

Protects *SYSBAS data

IBM PowerHA only protects data in Independent Auxiliary Storage Pools (IASPs). As a result, it leaves data in the system Auxiliary Storage Pool (ASP), known as *SYSBAS, unprotected. MIMIX for PowerHA replicates all data in *SYSBAS, to provide complete protection for your data and applications.

When you use MIMIX for PowerHA to complement IBM PowerHA, even applications that are not certified for the IASP are fully protected against downtime and data loss.

Maintaining multiple recovery servers that are active and ready to switch allows you to protect your critical data and applications at all times so that a single recovery server does not leave you vulnerable. MIMIX for PowerHA, when used in conjunction with MIMIX Availability, enables you to manage a multiple server HA/DR environment.

Protection during planned maintenance

When you perform maintenance on what is normally your production server, you can switch to your recovery server and keep the business running on it, but if that's your only recovery server, your data will not be replicated until the primary server is brought back online. Because disasters happen on their own schedules, you may lose considerable data and application availability if one strikes at that time.

Using MIMIX for PowerHA with MIMIX Availability to maintain multiple backups – possibly one local backup for use during maintenance, and one remote backup for disaster recovery – protects your data and applications from disasters at all times, including when your production server is down for maintenance.

Protection against simultaneous outages

Disasters are rare and simultaneous disasters, or a combination of a disaster and another downtime event, are even rarer, but they are not impossible. Using MIMIX for PowerHA with MIMIX Availability to maintain multiple recovery servers, possibly in different locations, helps to protect against downtime and data loss that might otherwise result from simultaneous outages.

Replicated servers maintained by MIMIX for PowerHA in conjunction with MIMIX Availability can be used for purposes other than high availability and disaster recovery purposes. Because they continuously contain a real-time copy of production data, you can create replicated servers for use as:

  • Data warehouses
  • Query and reporting servers
  • Sources for offline backups, or
  • Any other read-only jobs

And by moving those workloads to replicated servers, you can accomplish all of that without any additional strain on your production server.

What's more, when multiple application servers need to share the same data, you can use MIMIX for PowerHA, coupled with MIMIX Availability, to replicate data from one production server to another transparently, without the need for manual intervention.

A successful switch from your production server to a recovery server requires constant vigilance to ensure that the switch will not fail or be delayed due to changes in the environment. MIMIX for PowerHA checks for conditions in the IBM PowerHA environment that might jeopardise or delay a successful switch and sends a notification when it detects one. This allows you to resolve issues immediately rather than waiting to discover problems during a switch, ensuring the fastest possible recovery time.

Audits automatically performed by MIMIX for PowerHA include the following:

Duplicate library name detection

Switchable IASPs cannot contain a library name that is the same as a library in *SYSBAS. On an IASP vary-on, a check is performed. If a duplicate name exists, the vary-on will fail. If this occurs during a switch, the switch will fail. MIMIX for PowerHA monitors for duplicate libraries and provides a notification when a duplicate library name is detected, rather than waiting until the switch vary-on is in progress.

User profile configuration audit

User profile assignments that differ on the production and recovery servers need to be resolved at the time of the switch, increasing the switch time. MIMIX for PowerHA detects these conditions when they arise so that the environment can be updated immediately and maintained in an optimised state.

Library ratio audit

There is an optimum ratio between libraries in *SYSBAS and libraries in the IASP to reduce the vary-on time and, thus, the switch time. MIMIX for PowerHA highlights this ratio so that the environment can be maintained in an optimised state.

Extended protection with MIMIX Availability

MIMIX for PowerHA, when paired with MIMIX Availability, extends IBM PowerHA HA/DR protection, enabling replication of real-time data to additional local or remote servers for disaster recovery or other purposes. These additional copies of the data can be accessed in real time for a variety of purposes and are kept in sync when production is switched to a backup server.

MIMIX for PowerHA continuously monitors for duplicate library names between *SYSBAS on the target server and the IASP on the source server, providing timely notification when a new library with a duplicate name is created so that it can proactively be renamed or moved before any planned or unplanned outage occurs.
