HA/DR BACKUP

Implementing Continuous Availability
By Shirley S. Savage

N

atural disasters such as
hurricanes and earthquakes
can cause outages. So
can electric power disruptions,
cyberattacks and human error.
Outages are expensive. The cost of
a cyberattack is estimated at $1.1
million while the average cost of
network downtime varies from $5,600
per minute to $22,000 per minute,
depending on the industry. These
days, organizations are expected to be
continuously available no matter what
happens.
Two successive hurricanes were
the catalyst for the Department of
Treasury of Puerto Rico to upgrade
its systems to increase resiliency. The
treasury crafted a plan to restore its
system should its IBM Z* server be
affected by an outage. The treasury
worked with IBM, Truenorth and PSR
to create a comprehensive disaster
management system based on
IBM Z solutions. It installed an IBM
z14* server to replace its existing
mainframe. IBM Global Mirror
enables the treasury to replicate data
asynchronously to another IBM z14 at
a disaster recovery (DR). The treasury
also upgraded its storage system with
IBM DS8884 storage and IBM TS7760
tape systems.
With the new DR system, the
treasury is confident that its
applications will be operational at

the DR site. The recovery window is
estimated to be 35 hours, although
that could be reduced to a couple
hours with additional configurations
and hardware.
Puerto Rico's experience highlights
five DR best practices: redundancy
protection, automate where possible,
test your system, document processes
and innovate for the future.
"We never know when another
hurricane may hit Puerto Rico, but at
least we know that we're now better
prepared to absorb the impact and
recover quickly," says the treasury's
CIO Raúl Cruz Franqui ("Puerto
Rico's Disaster Recovery Planning Is
a Blueprint for Data Protection," bit.
ly/2oDkBR7).

The Need for
Continuous Availability
Continuous availability (CA) has
become the preferred standard for
system availability. Pressure from
regulators, stakeholders and customers
for 100% availability has enterprises
looking for the best practices to keep
their systems up and running.
CA is made up of two parts,
according to David Petersen, IBM
Distinguished Engineer and chief
architect of IBM Geographically
Dispersed Parallel Sysplex (GDPS).
High availability (HA) masks
unplanned outage and continuous

operations (CO) mask planned
outages. DR comes into play when HA
isn't available.
Three major trends are driving
the need for sophisticated CA/DR
solutions, says Nick Clayton, IBM
Distinguished Engineer, Enterprise
Storage Development. They are:
* The time to recover from
outages is shrinking
* All industry segments need
to improve CA/DR
* The need to recovery quickly
from logical data corruption
and destruction is driven by
concerns about ransomware
and other cyberattacks
CA/DR methods need to go further
than having multiple geographically
disperse copies of data. CA/DR must
have multiple and frequent snapshots
of live data as well as tools to detect
data breaches, a determination
of when the data was corrupted
and recent, clean data to use for
restoration.
IBM GDPS automates the CA/DR
process for clients. It can also scale to
three- and four-site configurations,
giving clients a robust backup
solution. CA is well within every
client's reach ("IBM CA/DR Solutions

Threats," bit.ly/2VCBU0G).
