When CPS Energy implemented an Enterprise
Resource Planning (ERP) environment a decade
ago, the nation’s largest municipally owned energy
utility was able to streamline its business operations
and align its technology more closely to its
business processes.

Today, the new infrastructure supports Oracle and
web-based applications across a variety of functions,
including customer relationship management,
call center services, and online customer account
management. It also provides a foundation for future
technology-based services, such as smart metering
applications to streamline the tracking of customers’
electric and gas usage.

Given the critical nature of these processes,
however, the CPS Energy technology organization
needs to ensure that the databases associated
with the infrastructure are protected against loss or
corruption. For this reason, CPS Energy uses HP Data
Protector software as the backup solution for its ERP
environment and HP Integrity servers with HP-UX to
provide a mission-critical platform. This easy-to-use,
flexible software solution provides CPS Energy
with the functionality it needs to perform ongoing
backups of its ERP system data, and restore that
data quickly when needed.

Rock-solid data backup

CPS, which was acquired by the City of San Antonio,
Texas in 1942, serves a population of 707,000
electric and 322,000 natural gas customers in San
Antonio and surrounding communities. CPS customers’
combined energy bills rank among the lowest of the
United States’ 20 largest cities. The utility also prides
itself on the reliability of its services, its commitment to
renewable energy—16% of its energy is derived from
wind, solar and landfill-generated methane gas—and
its participation in local community service and
charity programs.

“When developers or testers need a copy
of our production environment, we can
give it to them without impacting our
normal backup procedures.”

and UNIX Supervisor, CPS Energy

Today, CPS runs SAP as its core ERP platform,
It is standardized on HP hardware for its UNIX
environment, including HP Integrity servers, HP-UX
Operating Environment, and HP XP24000/XP12000
Disk Arrays.

As a municipal utility, CPS operates under a unique
combination of constraints and responsibilities. “We
have to move slowly when it comes to implementing
technology,” explains Suzanne Shuler, Infrastructure
Services and UNIX Supervisor, CPS Energy. “We
are publicly funded. We have a responsibility to
our community to exercise great care with how we
allocate our budget.”

In addition to being budget-conscious, CPS Energy
must also consider how its technology choices impact
customer service. “We standardized on HP Integrity
servers running HP-UX because we need to run our
company on a reliable platform end-to-end,” notes
Frank Salinas, Network Administration Analyst.
“We need to ensure that our website and call center
services will be available when customers need to
reach us or check on their accounts. HP Integrity
servers with HP-UX deliver the performance and
reliability we require.”

The utility’s HP-UX environment and HP Serviceguard
Solutions drive infrastructure availability with functions
like automated fault detection. And CPS Energy backs
its systems with HP Mission Critical Services. “We
require a high level of service to reduce the risk that
an outage might impact our customers,” Salinas says.
“With HP Mission Critical Services, we have 24 x 7
support on our infrastructure.”

A final way CPS Energy ensures it fulfills its
responsibilities to its customers is by maintaining
rock-solid data backup processes and technology.
“Our priority as an IT organization is to ensure that
our data is fully protected, and that it can be easily
restored whenever necessary,” Salinas notes. “If we
didn’t have backups, it would be catastrophic for CPS.
All of our financial data is housed in the systems that
the Data Protector backs up. Payroll or customer
billing would be impacted if we lost data. It is
critical that backups occur regularly.”

CPS Energy follows industry best practices for
its backup processes, using HP Data Protector to
perform backups to tape of the utility’s production
systems up to eight times per day—more often for
large production systems than for smaller databases.
Backups may comprise anywhere from a terabyte and
a half to four terabytes of data. They are scheduled
during non-peak hours. Data is backed up to an HP
Enterprise Systems Library (ESL) Tape Library. To meet
the performance requirements of backing up over
96 TBs per week, the team uses direct attached fiber
channel drives to multiple cell managers and media
servers to stream data at very fast rates.

To meet the utility’s disaster recovery (DR) requirements,
the backups are performed across two data centers.
“We have four HP ESL Tape Libraries altogether, with
nine drives apiece,” Salinas explains. CPS has also
split the infrastructure into two master servers (Data
