#IBMEDGE © 2012 IBM Corporation

Confused over the different types of
cloud storage? IBM's scale out network
attached storage (SONAS) can be used
in a variety of use cases. This session
will provide an overview of IBM's SONAS
solution, provide an update on the latest
features and functions recently
announced, and explain how it can be
deployed in various private, public and
hybrid cloud environments.

The Problems with NAS filers
today

• Current NAS solutions do not scale
• Customers have to add box after box
and manage them individually
• Difficult to apply policies across
independent data islands

Active Cloud Engine™
What is IBM Active Cloud
Engine™? Think of it as a very
smart, very fast robot – that
never sleeps – keeping your
cloud storage neat, tidy, and
running smoothly…

On SONAS, the IBM Active Cloud
Engine™ provides:
• Policy-based file management
• High Speed Scan engine to
identify files to be processed
• HSM migration of files to tape,
with transparent recall
• WAN caching across distance

SONAS – HSM and
Information Lifecycle Management
• Capacity managed centrally
• Average utilization >80%
IP Network
• Policy driven
File placement – direct new

Performance is based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput or performance that any user will
experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and
the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated
here.

Prices are suggested U.S. list prices and are subject to change without notice. Starting price may not include a hard drive, operating system or other features. Contact your
IBM representative or Business Partner for the most current pricing in your geography.
