GDPS Global Solutions
As the name suggests, GDPS Global
solutions use Global Mirror or z/OS
Global Mirror, which are both asynchronous replication technologies
to replicate the data over unlimited
distances. They provide replication
management and monitoring of
the steady-state environment along
with the orchestration, through
"!)É$'Ã)!$¯!)QÃ!Ã$ÉÇ!(É$1ÃÄÇtions in the disaster recovery (DR)
region in the event of a production
region disaster. GDPS provides the
ability to toggle between these two
regions if this is a stated requirement. With asynchronous replication, some degree of data loss
is always expected in unplanned
scenarios, but this is typically in
the low seconds range. RTO will be
30-60 minutes, depending on how
long it takes to restart systems and
workload in the DR site.
GDPS Metro Global Solutions
These three- and four-site solutions combine elements of the Metro and Global solutions to deliver
Metro distance near-continuous
availability along with region DR
capabilities. With this combination
of three- or four-site solutions and
capabilities, clients can deploy a
solution that addresses the best of
both worlds. Local resilience will
be protected from single or multiple component failures within
the production region, while
out-of-region protection is provided by GDPS Global capabilities.

those focused on the most stringent availability targets, such as
&Éî Ä ÇÉÃ È'%&$1QÃÄ$ÉÃÆÉ Ã$Éulated to demonstrate the ability
to run in both their normal and DR
locations for extended periods of
time to validate stated capabilities.

GDPS Continuous Availability
The GDPS Continuous Availability solution uses software-based
replication of data provided by
IBM InfoSphere* Data Replication
for z/OS for Db2*, IMS* and VSAM
data types. It provides low recovery times for the most critical
workloads in a client mainframe
environment. This is achieved by
having a sysplex active at all times
in two different regions that can be
separated by any distance, so long
as the software-based replication
can be provisioned (along with
network connectivity) between
them. No requirement exists for a
clustering solution between the regions. GDPS provides monitoring
and orchestration of various components that comprise the overall
solution, ensuring that, when a
failure is encountered by a workload, that workload is switched
to the alternate region with the
minimum delay.
&!$ÃÄÃ(%'ÄÃ!Ã'$03ÃÇ! ®'$Ätions, see Figure 1 on page 52.

Automation and
Orchestration Are Key
Automation to remove the need
for direct human intervention at
the time of an event occurring, and
orchestration of recovery actions
are both critical to achieving the
highest availability levels possible.
GDPS solutions are designed to
provide automation as close to the
objects being automated as possiÆÉÃ!$ÃÄ0'ÃÉ®ÇÉ Ç1NÃ'$03Ã
Ä%!Ã"$!(ÈÉ%ÃÄÃ"!)É$'Ã)!$¯!)Ã
engine and a simple script language to orchestrate actions often
required in either planned or unplanned events in a repeatable and
predetermined way.
Even with the most available
systems infrastructure we have
today, GDPS solutions increase
the resilience of the overall environment and enable hundreds of
mainframe clients to meet availability and DR objectives.

Get Real-Time
Insight and Data
Security With
Open Data
Analytics for z/OS

O

pen Data Analytics for z/OS*
allows you to implement
a modern analytics architecture by bringing your applications close to your enterprise data
sources. It solves the challenges
associated with moving the data to
a physical consolidation point such
as a data lake to perform analytics.
Moving the data to a physical data
lake often results in issues of data
freshness, data latency, data security and data governance.
By leveraging key strengths of
the IBM Z* software stack, Open
Data Analytics for z/OS can provide
superb scalability, performance and
resource management for analytic
workloads. One of the strengths of
the IBM Z platform and z/OS is the
ability to run multiple workloads at
the same time within one z/OS image or across multiple images while
maintaining high system utilization.
Leveraging this framework to
analyze data in place enables clients to use more current data, gain
additional insight and preserve the
security and governance of data.

Joe Bostian is an architect and
developer of middleware projects and
application frameworks for IBM Z.
