The HP AlphaServer GS1280 system will save us a lot of
money because the capacity far exceeds our expectations. We originally thought we would have to
double the size or add another server. Now, because of the performance we are seeing, we are quite confident that we will
be able to get through this year and into next before we have to add more database capacity.

CareSuccess story:Breakthrough performance of new HP system exceeds capacity needs
of Aurora Health Care
Finding a better way Every organization welcomes growth,
but not necessarily the growth pains that go along with success. When Aurora Health Care hit the capacity ceiling with its
database server, an HP Next Generation OpenVMS AlphaServer GS1280 system relieved the pain by delivering a quantum
improvement in performance.Aurora Health Care is a not-for-profit health care system and a
national leader in efforts to improve the quality of health care. Serving the eastern third of Wisconsin, Aurora provides
services along the entire continuum of care, from disease prevention through treatment and rehabilitation.
Aurora Health Care was formed in 1984 with an affiliation between
two Milwaukee hospitals and has been on an impressive growth path ever since. The organization was created around a single
idea: There is a better way to provide health care. Aurora strives to give people better access to care, better service and
better results than they can get anywhere else. The organizations primary application is Cerner
Millennium, a comprehensive solution that enables health care providers to capture all patient information in one electronic
medical record. Aurora runs Cerner Millennium and the Oracle® database on an HP OpenVMS AlphaServer
cluster.Capacity headaches Our biggest challenge, says
Oettinger, is to provide the computing capacity to continue to implement the Cerner application in all of our hospitals
and clinics. Aurora runs a centralized IT environment at the organizations headquarters in Milwaukee. The entire Cerner production environment runs on four
AlphaServer systems three servers host the application and one hosts the Oracle database. Eight additional
AlphaServer systems make up an elaborate test and certification system that supports the production
environment.We have one terabyte of data for production, says Oettinger. Of that, 750 gigabytes is live data. We have a total of approximately six terabytes of storage.
Our entire storage architecture is HP StorageWorks. Our production storage is on a SAN with EMA12000 arrays and four disk
arrays that support our production environment. We will be moving our production database to two
EVAs.While storage capacity can be added incrementally, database
capacity could not because the Cerner and Oracle combination currently requires that the database run on a single
server.The database machine was the bottleneck in our architecture, explains David Harrold, Senior Systems Engineer at Aurora. We were averaging utilization
of 85% to 87% with spikes of 100% utilization, which was slowing down the application and inhibiting our ability to roll
out Cerner Millennium in new facilities.The right prescription The solution to our capacity
challenge was an AlphaServer GS1280 system, says Oettinger. On the first day in production, it averaged 16%
utilization. During prime time utilization, it has not exceeded 25%. So with this single system, we
have gone from 90% utilization to 25% utilization. Now our users are happy, and we can sleep at
night.Aurora is the second largest OpenVMS user within the Cerner
customer base. Cerner considers us to be on the cutting edge in capacity planning, says Oettinger. We
spend a lot of time planning for future capacity requirements and trying to stay ahead of the
game.Aurora worked closely with HP to configure a system that would
meet its hefty capacity needs. Harrold explains, We were hoping for a two-and-a-half to three-times gain. In effect, we
got a four to four-and-a-half times gain. Before we saw what this server could do, we thought that we would have to upgrade
to 32 CPUs in several months. But I am now confident that the current configuration will last at least a year as we add three
more hospitals and 20 to 30 more clinics to the system.Aurora is always looking to find a better way, and to do
that were looking toward the most current technology in the health care field. We are committed to HP technology,
and we also work with Cerner Corp., a leader in totally integrated health care systems. Lee

Scarily easy upgrade There were no headaches when it
came to upgrading from the older AlphaServer system to the next generation AlphaServer GS1280 system. Harrold explains,
We had the machine about a month before we put it into production. The upgrade was scarily easy. During our normal
Sunday outage window, we shut down the AlphaServer GS140, changed the configuration so that the AlphaServer GS1280 booted in
that node in the cluster, booted it up and we were off and running.Before the upgrade, users were experiencing slow response times
during periods of peak utilization. There are a lot of people who are happy with the way the
application runs now, and they are using it more, comments Harrold.Harrold says that HP has helped with capacity planning. We
have a very good relationship with our local account team. They do a very good job of getting us information about
whats going on and whats coming. We work closely with the OpenVMS engineering group and theyve been very
helpful. We also have a good team in the local field service office, and they installed the new server for us. We work well
together.Staying ahead To maintain 24x7 availability, Aurora has a
standby system for planned and unplanned outages. At those times, the IT team switches users over to a separate
read-only database running on a separate cluster. Another capability Aurora has just implemented is web access to
the Oracle database. I think we are one of the first Cerner users to be able to provide read-only web access to
the database, says Harrold. We designed and set it up as part of an outage contingency, but now people are using
it from their offices and homes on a regular basis. Its much more popular than we initially thought it would be.
Oettinger adds, Cerner will probably have web access within a year, and we will take full advantage of that.In the meantime, the IT teams directive is to roll out the Cerner application to all Aurora facilities. Cerner Millennium is allowing us to have a totally
computerizedpatient record where virtually all the patient data is in one
place and available at every Aurora location, says Oettinger. We currently have Cerner installed at 50% to 60% of
all the Aurora facilities. Our key goal is to roll out the computerized medical record to every Aurora location and have
everybody using it. The beauty of HP is that we can maintain the same operating system, application and database we
just add more hardware.The hardware roadmap for Aurora looks like it will lead to the
industry-standard Intel® Itanium® architecture. Im sure that in the future we
will move to the Itanium®-based platform, states
Harrold. We will probably run a mixed environment for a while, which OpenVMS clusters will allow us to
do.As a matter of course, HP technologies will continue to support
Auroras mission to find a better way to deliver health care.Ive been working with OpenVMS for about 15 years,
and theres no other operating system that can touch it in my opinion because of the stability thats
been evidenced over the years and the security thats built-in. And the clustering is one of the best technologies
thats ever existed. Nobody else can hold a candle to what OpenVMS clusters provide as far as scalability and
reliability. David Harrold, Senior Systems Engineer,
