Gwinnett Medical Center relies on HP to help meet care goals
Leverages HP storage and server solutions to manage growth and costs
“Our No. 1 technology challenge continues to be managing explosive
growth – particularly when it comes to data. Five years ago, we were
managing about a terabyte of data. Today, we have more than 250 TB with
no signs of slowing.”

Gwinnett manages growth pains with teamwork
Gwinnett Medical Center serves Georgia’s Gwinnett
County – one of the fastest growing counties in the
United States. Located northeast of Atlanta, the
county’s population has increased by more than 11
fold in the past 40 years. The Gwinnett Medical
Center – with four hospitals, 500 beds and 800
physicians – provides care to more than 400,000
patients annually. In recent years, the hospital system
has experienced nearly 100 percent occupancy,
prompting the construction of new facilities including
the Gwinnett Medical Center in Duluth, GA, and a
155-bed patient tower addition to the Gwinnett
Medical Center in Lawrenceville.
Despite the challenges posed by unrelenting demand
for new and expanded services, Gwinnett has
consistently maintained the highest levels of patient

Gwinnett recently upgraded its HP SAN fabric with HP
StorageWorks 4/256 SAN Director B-series directorclass switches. The powerful 4 Gb/s Fibre Channel
switches provide robust, continuous operation with
built-in redundancy and hot-pluggable components.
“Our upgrade to HP director-class switches was
another step in our goal of 100 percent uptime,” Allen
says. “In the past, to upgrade a small switch we would
have to take the whole thing down. Now, we can
perform upgrades and failovers from one switch to
another and maintain availability across the fabric. HP
pre-sales engineers validated our design and we
implemented the switches ourselves.”
Clear choice for image archiving and availability
HP EVA-based SAN and HP MAS systems enable
Gwinnett to efficiently manage explosive growth in
storage demands. “Just five years ago we had about
one terabyte of total storage on the floor,” Allen notes.
“Today, we’re managing 250 TB, and we are about to
care quality. According to Rick Allen, Gwinnett’s

were one of the earliest users of the HP Enterprise
Virtual Array (EVA) storage systems, and we worked
hard to certify the HP Medical Archive solution (MAS)
with our McKesson Picture Archive and Communication
System (PACS) back in 2003,” Allen explains. “We
have worked with both HP and McKesson on many
other applications that are critical to our operations.”
Robust HP storage solutions are highly manageable
and vital for hospital information
Gwinnett uses its HP EVA storage-area network (SAN)
system – which features five EVA systems split between
its two data centers – to support almost all of its critical
clinical and enterprise management applications. For
example, the EVA SAN supports the hospital system’s
full range of McKesson applications, including
electronic medical record, pharmacy, physician portal,
surgical management, PACS and radiology operations.
“We have a small staff to manage all of our storage
resources,” Allen notes. “When we originally made the
move to a SAN environment, we compared the HP
EVA systems to everything else on the market –
including IBM, EMC, Xiotech and many others. I came
from banking and would have bought Big Blue if given
the chance, but the HP EVA was the easiest to manage
– bar none. For each expansion since then, we have
looked at all of our options and made sure that the
EVA was still the right choice. It gives us the
availability we need and the virtualization layer makes
it easy to manage. If it’s important to us, we put it on
the EVA.”
Along with painless storage growth, HP MAS provides
Gwinnett with essential image archive management
capabilities, uptime and performance. The hospital
system performs and stores more than 350,000 new
digital imaging studies annually. HP MAS gives
Gwinnett asynchronous replication of its PACS image
data between the hospital system’s two main data
“When you start talking about things that make me
lose sleep at night, online medical data access is the
biggest concern I have,” Allen says. “We’re quickly
getting to the point where every piece of medical
information will only be available online. There will
soon be no paper records or charts. Our systems must
be built for near 100 percent uptime; nothing else will
The hospital system recently migrated its entire
cardiology image archives – including catheterization
lab, echocardiography and vascular ultrasound – to
HP MAS. “We had been storing cardiology images on
DVDs,” Allen explains. “Our data center operators
were spending valuable time chasing DVDs, rather
than doing their proper functions. Moving the cardiac
image archiving function to HP MAS has saved us at
least one-quarter FTE (full-time equivalent person) –
time that was previously tied up mounting, moving and
storing DVDs.”
“Our HP-based technology solution ultimately
yields faster time-to-diagnosis and treatment for
our patients. On the business side, we’re more
protected, efficient and compliant. In addition,
we can recoup patient payments faster, and save
money on power and cooling – a huge plus in these
hard economic times. HP has also helped us
improve our bottom line while becoming greener,
and that’s a great combination.”

Katrina teaches importance of continuity
According to Allen, Gwinnett plans to protect patient
data even further by replicating medical images to a
remote HP MAS grid at a secure storage facility at Iron
Mountain. This off-site disaster recovery will provide
additional protection in case a regional disaster wipes
out Gwinnett’s two main data centers.
“I learned a powerful lesson in the Katrina disaster,”
Allen explains. “Most of my family lived in the New
Orleans area and they were forced to move when the
hurricane struck. My grandmother’s medical records
were completely lost in the flooding. I know what level
of protection we have to provide to our patients. If we
lose everything here at Gwinnett, we’ll just need to get
a PACS system up and running anywhere in the world
and we can point it to the copy on the HP MAS at Iron
ProLiant DL580 servers to support the Oracle 10g RAC
database layer and ProLiant c-Class server blades for
the new solution’s application layer.
Explains Allen, “We are deeply involved in the
development of this new McKesson solution and,
therefore, influence many design decisions – including
the platform it would run on, HP servers. It’s perfect for
us because we get an end-to-end HP solution that we
know is going to deliver the availability and
functionality we demand.”
For many new and some existing applications,
Gwinnett relies on VMware virtual servers running on
HP ProLiant physical servers; whenever possible, the
servers are HP server blades. “By emphasizing HP
blade technology and virtualized servers we are
beginning to achieve greater efficiency in floor space
and energy use. We are very space challenged in our
data centers, so saving space has been our number
