of stability and availability so your
workloads can run continuously.
But the IBM z15 isn't the only
IBM Z innovation you should
leverage. These innovations can
help you get the most out of the
platform:
Parallel Sysplex
A sysplex is a clustering technique
for multiple z/OS* images and is
used so images can cooperate with
one another and use resources
more efficiently. Parallel Sysplex,
a more complex version of this
technology, uses multisystem data
sharing technology. IBM Z workloads can be built to take advantage
of this technology to share resources and data, and to have continuous
availability and failover. Shared
data can support concurrent read/
write access with no impact to data
integrity or performance. Parallel
Sysplex relies on coupling facility
LPARs or internal coupling facilities (ICFs) that provide the data
sharing capability to the LPARs
within the cluster or plex.
Mainframe applications must be
designed to be sysplex-capable. Start
with an end-to-end component model. The areas that need augmentation
will become apparent.
LPARs
The creation of LPARs can look like
a stream of consciousness sometimes. There are valid reasons for
creating LPARs, which will vary
widely from company to company.
An optimal configuration would be:
*
*
*
*

Two mainframes
Two sysplexes
Each sysplex spans both
mainframes
Two LPARs in each sysplex

The IBM Z network
IBM Z systems and applications
should take advantage of virtual
IP addressing (VIPA). VIPA removes the IP address association
with a physical link and keeps

the IP address active. In short,
each address space or application
region and LPAR can have its own
VIPA association. This allows for
the dynamic movement of these
processes in the event of a planned
or unplanned outage.
Multiple LPAR systems should
take advantage of HiperSockets, the
fastest method available to transfer
data between them. HiperSockets
provides the fastest TCP/IP connection within the mainframe and
eliminates the need for internal
physical connections.
Storage
IBM Z DASDs can snowball into a
complex mess on the actual hardware without careful, thoughtful
engineering. The data should be
viewed as your most important
asset. If mined correctly, this data
can enable your IBM Z operation
to become more efficient, allow
you to locate problems before they
become outages, and provide your
business insights to grow and become more profitable.
Working from the access level
toward the hardware, your IBM Z
platform should be able to:
*
*
*
*

*

Isolate test data from production at the hardware level
Designate isolated test and
production LPARs
Achieve sysplex isolation
Synchronously replicate storage locally and asynchronously
remotely
Encrypt all IBM Z data (in, out,
inside and access points)

Whether you replicate synchronously or not will depend on
your outage toleration level. Local,
synchronous replication with asynchronous remote replication positions you for zero downtime. Lastly,
encrypting everywhere is possible
with the new IBM z15. Encrypting
your IBM Z data at rest and in flight
ensures that your data is seen only
by those authorized to see it.

Modern and
Cost-Contained
DevOps
Mainframes power the world,
processing vast numbers of
transactions across countless
mission-critical applications.
The teams behind this success understand the value of
comprehensive change and
release management and have
long-practiced mainframe variations of DevOps.
Still, today's enterprises rely
on complex networks of applications spanning mobile to cloud,
and new generations of DevOps
methodologies are deployed
where mainframes are part of
a larger picture. This creates
pressure on mainframe sites; with
today's dispersed development
and operations teams, cost
becomes a concern. Historic
cost-cutting methodologies like
software quarantines are often

Regardless of what DevOps

Virtualizing and cloud-enabling
relevant mainframe applications provides your preferred
DevOps toolchain everywhere
you need it, while limiting costs
of additional software licenses
or capacity. Today's mainframe
application virtualization, cloud
and software-as-a-service
options combined with creative
partnerships, are powering the
next evolution
of a modern
and cost-contained
mainframe
DevOps.
