Enterprise Storage Management
• To date ESM is an ad hoc collection of
disparate tools, predominately independent
device management utilities.
• ESM is the number one cost (and potential
cost saving) portion of the data 2000 IT
departments moving forward.

Enterprise Storage Management
• What Do IT Objectives Call for?
1. The ability to understand what they have
2. Understand usage patterns by storage
assets
3. Understand usage patterns by line of
business
4. An easier way to guarantee information
availability in order to meet business
objectives

Enterprise Storage Management
• What Does IT Operations Want?:
1. The ability to modify their storage world
2. The ability to create storage policies
3. The ability to restore – 100% of the time
4. The ability to USE disparate hardware assets

Enterprise Storage Management
• Storage Resource Management
– SRM provides (at a base level) the
ability to discover assets and correlate
them to users/application, etc.
– SRM provides the ability to visualize
what data is where – what is duplicate,
what is wasting space, what is being
backed up that shouldn’t be.

Enterprise Storage Management
• Virtualization
– The great equalizer – it allows you to
neuter the “brand”, creating equality
among array vendors. Creates the
ability to “use” disparate assets.
Enables heterogeneity.

• Data Management
– Backup/Restore/Bus. Continuance,
H/A, HSM, etc. Data Management
delivers the key components of
information life cycle management.

• Storage Network Management
– SNM delivers topology mapping and
discovery, device management, zoning,
multi-pathing, etc. in order to enable a
visual overview with the ability to drill
down.

• Storage Policy Management
– User policies are implemented, which
feed (ulitmately) automated processes
in all other areas. Likewise, all other
ESM areas feed into the Policy Engine.

• Today we are still at the starting gate:
–

–
SRM works
Virtualization is new
Data Management is proven
SNM is really only device management and
rudimentary topology mapping.
– Policy Engines exist sporadically but are not
well integrated.
