the catalog and polls the volumes
directly. On average, systems that
allowed this condition had 15% uncatalogued data. Without exception,
these were categorized as disposable and sometimes hadn't been
opened since the early 1990s.
Secondly, an average of 1.6% of
data was found to be uncatalogued

The most valuable discovery was
that 40% of the 4 PB of tape data fell
into the category of disposable. Disposable data on disk ranged from
12% to 25%. Determining how to
dispose of this data was prioritized.

The Data Growth Paradox
From these results, we see that
data can pose a legal liability. The
larger the data lake, the greater the
loss during a data breach. Data can
also be used against a company in a
legal action. If it outlives its usefulness, and no legal reason exists to
keep it, deleting it can reduce risks.
We also see that risk and cost are a
function of the size of the data lake.
This brings us to the paradox
companies can face when creating
a data-retention policy. In general, the average data owner doesn't

retention of their data. For example,
they may be able to identify tens of
thousands of tape data sets to eliminate but are only able to accomplish
this by recalling and deleting each
data set one at a time. The system
caretakers have the skills to automate the deletion process but
cannot take on the risk of deleting
client data without permission. Getting this permission takes immense
time and effort. Data continues to
grow at alarming rates and any hope
of taming this growth requires more
aggressive procedures.

Raising the Bar on IBM Z
Resiliency With GDPS

W

ith the recent push toward
digital enablement and
always-on infrastructure,
organizations are striving to ensure
their IT infrastructure can deliver
service irrespective to any outages
or events that befall them.
The IBM Z* platform provides
industry-leading availability characteristics based on the inherent
strengths of the overall platform.
Technologies such as Parallel Sys-

plex data sharing and data replication are fundamental to providing
this availability, and they can be
further enhanced by deploying
automation and orchestration solutions such as GDPS.

GDPS Solutions
GDPS is a family of solutions

David Clitherow is the global offering manager for the High Availability
Services portfolio within IBM Global Technology Services, which includes
the GDPS family of solutions.
