2. 2 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.

4. 4 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

5. 5 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

9. 9 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.

10. 10 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.

11. 11 Enterprise Storage Management Data Management –Backup/Restore/Bus. Continuance, H/A, HSM, etc. Data Management delivers the key components of information life cycle management.

13. 13 Enterprise Storage 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.

15. 15 Enterprise Storage Management 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.

16. 16 What Needs to Be Considered? Storage Management Attributes Type of Content Quality Of Service Size Protection Levels Locations Backup & Archiving Policies

17. 17 Enterprise Storage Management 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.
