How Resilient Is Your IBM Z
System of Record?

T

o ensure that IS organizations deliver resilient service,
IT architects must have systems that rapidly adapt to unforeseen events, including disruptions,
business demands or security
threats. The IBM Z* server provides
that level of resiliency for systems
of record, not only for core CICS*
workloads, but also for new technologies like machine learning and
analytics applications as well as a
web infrastructure that supports
high transaction rates for 24-7-365
operations.

Customers, employees, shareholders, supply chain partners and
communities depend on your systems' continuous availability (CA).
While your business can recover
from an hour of downtime, additional hours of interruption from
poor restoration objectives could
jeopardize your organization's
long-term health and relevance.
Mainframe shops typically introduce a z/OS* cluster with several
z/OS images sharing a common
time reference, called a z/OS Parallel Sysplex, as an initial step to

achieving CA. Redundant system
resources can then recover at the
point of an incident, and enable
a rapid cross-system restart. For
planned outages, existing resource
can absorb the workload. Another
step to improve resiliency is enabling workloads to share databases and other logical resources in a
Parallel Sysplex with much faster
recovery times, eliminating or reducing any outage with little or no
data loss.
CA is achieved by mitigating
both planned and unplanned
outages. Recovery objectives for
data center component failures
are often expressed in seconds or
minutes, depending on technology
used and how well the installation's system recovery actions are
automated. Disaster recovery (DR)
is also critical to handling events
that result in a full data center
outage. Restoration objectives for
disasters are usually expressed in
hours, including the time to switch
operations over to an alternate data
center using replicated data. The
IBM Z platform makes achieving
recovery objective times easy.

The IBM Z Resiliency
Maturity Model
IBM developed a Resiliency Maturity Model that maps a progression for mainframe clients
with different levels of resiliency
requirements. The model guides
organizations through assessing
current resiliency investments
and determining new targets for
business workloads. It also helps
with determining practical steps to
achieve availability goals within the
data center, and suggests DR considerations between data centers to
be included as part of assessments.
The Resiliency Maturity Model
describes four resiliency levels
that start with single server clients,
and lead up to a full CA environment that is fault-tolerant within the primary data center, and
