Welcome to the IBM Z® Resilience content solution, your homepage for technical resources and use cases for resilient server solutions for IBM Z.
IT resilience with IBM Z is the ability to rapidly adapt and respond to any internal or external disruption, demand, or threat, and continue business operations without significant impact. The goal is that you can run your workload 24x7, no matter what.
Learn how solutions for IT resilience can optimize availability, keep your systems running, detect problems in advance and recover your critical data. Examine the key benefits and capablities of IBM Z for resilience on the z15™ platform.
Minimize the impact of stopping and restarting z/OS.
Mirroring can be enhanced with the help of IBM Copy Services Manager (CSM).
- Multiple systems and data in two or more data centers
- Workload continuing even when a system fails
- Dynamic workload balancing
- Shared data with read and write access directly from any member of the sysplex.
A Parallel Sysplex also provides a common and consistent view of sysplex-wide shared data, called data sharing. Shared data can be directly accessed from any application region on any participating system in the sysplex.
A well configured Parallel Sysplex and its well constructed sysplex-enabled workload can be configured to have no single point of failure. A Parallel Sysplex is not dependent on the functioning of any single resource, any single CEC or operating system. If any one copy happens to fail or needs to be removed for maintenance, the workload as a whole can continue to run on another systems of the cluster.
With the introduction of GDPS Metro, end-to-end automated recovery is provided, even in the event that an entire data center becomes inoperative. A fully configured Parallel Sysplex data sharing environment, together with GDPS Metro support for HyperSwap for disk events, is designed to provide 99.99999% availability. GDPS Metro includes disk reconfiguration, managing servers, Sysplex resources, CBU, activation profiles, and so on. GDPS Metro is designed to be a near continuous availability and disaster recovery solution.
GDPS Metro extends the Parallel Sysplex redundancy to disk subsystems. The HyperSwap function can help significantly reduce the time needed to switch to the secondary set of disks while keeping the z/OS systems active, together with their applications.

Provides a synchronized, standardized approach to data generation that enables the ability to dynamically define and correlate disparate customer-specific performance anomalies without a predefined policy.This correlation capability helps you implicate or exonerate workload components, where correlated anomalous activities are identified and non-anomalous activities are exonerated.
A visually intuitive analytics engine designed to provide visibility into interdependencies and interactions across workloads and to dynamically recognize anomalous behavior across one or two interval periods over multiple subsystems. For more information, see IBM z/OS Workload Interaction Navigator in IBM Documentation.
Addresses the requirement for more frequent disaster recovery (DR) testing and emerging government regulations that mandate for extended operations out of DR sites. Provides a cost efficient way to move processing capacity between Production and DR sites for extended periods of time. IBM Z DR for Cloud works with Country Multiplex Pricing (CMP) or Tailored Fit Pricing Software Consumption Solution IBM software. For information about the Software Consumption Solution, see the Tailored Fit Pricing content solution.
Identifies potential problems before they impact your availability or cause outages. It checks the current active z/OS and sysplex settings and definitions for a system and compares the values to those suggested by IBM or defined by you.

In this engaging lightboard demonstration, IBM's Nada Santiago will show how you can build a resilient infrastructure and get back up and running faster with IBM Z and IBM LinuxONE.
This IBM Redbooks publication gives a broad understanding of resilience on the IBM Z platform and explains how it works and why it is important.
