Improving Healthcare
Data Management
Beyond Silos: Meeting the
Data Management Challenge

E M C P e r s pec t i v e

The Difficulties With Siloed
Medical Storage
Most healthcare organizations dedicate
specific PACS storage systems to each of
their diagnostic disciplines. This can create
certain difficulties:
• Dedicated storage creates multiple
storage silos, which can inhibit data
sharing across modalities and make
storage management more complex.
• Storage silos reduce utilization rates
and increase the inefficiency and cost
of data management.
• Storage silos inhibit the collaboration
between departments required for
accurate diagnostics and the development
of comprehensive treatments

A Deluge of Data
Managing the volume of data now a regular part of daily healthcare management operations
is a growing challenge. In the next four years, EMC estimates the amount of stored medical
image data will grow from 0.8 exabytes to nearly 4 exabytes. The amount of data managed
will continue to grow as healthcare organizations add new equipment and incorporate
data-intensive next-generation diagnostic tools into standard protocol.
Healthcare data is typically housed on siloed systems based on department usage or
specific function such as radiology. This “siloing” creates complexity; each storage system
must be managed separately, which makes data more difficult to search or share, and
which reduces storage utilization efficiency.
EMC® Isilon® scale-out NAS storage simplifies healthcare data management with a single file
system that manages data as a single pool of storage. A single file system reduces
management complexity and increases storage utilization rates. EMC Isilon solutions work with
all major PACS (Picture Archiving and Communication Systems) ISV applications used to store
medical imaging data, and easily scale at the push of a button to meet growing storage needs.

Trends driving a need for change
Several factors are forcing healthcare organizations to rethink their storage strategy:
More data to store: Storage capacity requirements continue to grow significantly with
the shift to data-intensive digital images for X-rays, ultrasounds, and other diagnostic
instruments, and with the increased use of diagnostic tests in general. As the number of
storage devices increases to support the rising volume of data, so too does the IT resource
capability required to maintain the growing systems.
Inefficient use of storage capacity: In most healthcare organizations, storage is
typically managed by diagnostic function or department. Each piece of equipment has
its own PACS with associated storage, which means the creation of multiple storage systems
requiring independent management throughout an organization. Since capacity is not
shared between modalities, this independent management of PACS storage systems
constrains data sharing. For example, a typical CT scanning system may require multiple
capacity upgrades over its lifetime, while a diagnostic X-ray system within the same
organization may have capacity to spare. With a siloed system, extra capacity cannot be
shared, and efficiency is lost. The inability to share surplus capacity between functional
areas regularly leads to healthcare storage utilization rates well under 50 percent. Siloing of
resources increases storage management cost, complexity, and inefficiency, which causes
healthcare organizations to buy more storage than necessary to meet the demands of
different groups.
Changing data retention requirements: Patient records, clinical study results, and
medical diagnostic images are now stored for longer periods of time. Additionally, State
and Federal data retention requirements continue to increase. While some data may be
appropriately archived to tape, most healthcare stored data needs to be immediately
accessible online. As more multidisciplinary and personalized treatments are introduced,
healthcare organizations will need to ensure extended access to shared data, especially
as the cost of lost data is so high.
Emerging diagnostic and therapeutic fields generate vast volumes of new data:
The adoption of new diagnostic imaging techniques and tools additionally increases the
generation of large volumes of data. Many healthcare organizations are experiencing a
rise in digital pathology and microscopy. The addition of sleep studies involving video
surveillance data, and the incorporation of next-generation sequencing (NGS) and
proteomics to customize disease treatments further extend the volume of data. Equipment
associated with these new fields can produce unprecedented volumes of data: for example,
2

a typical NGS study can create an additional 100 to 200 GB of data per study, per patient.
Current siloed storage infrastructures will not scale to meet this expanding data
management demand, and costs and complexity will continue to rise.

Infrastructure Management Complications Due
to Data Growth
To keep pace with the explosion of data, many healthcare organizations simply add raw
capacity with the purchase of dedicated storage for each new piece of equipment.
Unfortunately, while this provides disk capacity for individual diagnostic tool data, it
creates another siloed set of data repositories. Creating siloed storage adds more rack
space, more electricity and cooling, additional backups, and separate management of
each data volume. In most cases, this means running systems at low utilization rates
which translates to increased cost and management complexity.
Tight IT budgets may strain matters further, as healthcare organizations find themselves
with budgets unable to support increased storage needs. With siloed storage, costs and
management duties increase as more devices are added, forcing IT staff to divert time and
resources ordinarily spent on other projects. IT staff time is now dedicated to storage
management instead of growth, and CapEx and OpEx increase.

Seeking a Solution
Healthcare organizations need a unified storage solution that is highly scalable and highly
efficient, one that is able to meet the requirements of multiple modalities while offering
price/performance tiered storage that supports multidisciplinary computational workloads.
EMC Isilon scale-out NAS storage offers healthcare providers a path to simplify data
management, increase storage utilization, and achieve leading scalability.

EMC Isilon simplicity, scalability, and best-in-class
performance
EMC Isilon solutions are already used in leading healthcare organizations around the world,
providing +4 data protection and a single pool of storage that offers utilization rates over
80 percent. As the requirements of the provider increase, the EMC Isilon storage pool easily
scales at the push of a button to meet future storage needs, providing investment protection.
EMC Isilon hardware platforms are designed for simplicity, value, and best-in-class
performance. EMC Isilon systems currently can scale up to support 20 petabytes of storage
capacity, to over 100 Gbps of throughput, and up to 1.6 million SPECsfs file operations per
second in a single file system.
Every EMC Isilon solution can seamlessly scale on demand, enabling the healthcare
organization to add hundreds of terabytes of storage or expand performance in minutes. At
the same time, Isilon’s modular architecture and intelligent software make deployment and
management simple. Powered by its OneFS® operating system, every EMC Isilon cluster is a
single pool of storage with a global namespace, eliminating the need to support multiple
volumes and file systems. OneFS combines the three layers of traditional storage
architectures — file system, volume manager, and data protection — into one unified software
layer, creating a single intelligent file system that spans all nodes within a cluster. Unlike
simple NAS namespace aggregation products, the EMC Isilon OneFS operating system is truly
distributed and intelligently stripes data across all nodes in a cluster to create a single,
shared pool of storage. OneFS offers unsurpassed mission-critical reliability and industryleading drive rebuild times.

OneFS also delivers unique cluster-aware symmetric multiprocessing (SMP) capabilities
that enable the system to move tasks between processors for extremely efficient workload
balancing. In conjunction with the OneFS ability to stripe data across all nodes in a cluster,
EMC Isilon achieves the high aggregate bandwidth performance required to power
next-generation healthcare data centers.
As healthcare data is now retained for longer periods than ever before, more data is managed
online on different storage tiers based on each data type. To simplify management, EMC Isilon
offers a single file system with automated data migration between multiple tiers.
EMC Isilon also offers the industry’s first suite of scale-out storage data management
applications to meet critical data protection, access, management, and availability
