TRACK 3 (EXECUTIVE): Managing Storage -- A Plan of Attack

1. TRACK 3 (EXECUTIVE):Managing Storage -- A Plan of Attack Roles and Responsibilities in the Storage Group John Webster Senior Analyst and Founder Data Mobility Group

2. Agenda • Storage Management – a “practice” with multiple “disciplines” • Business opportunity vs. business risk – a balancing act • The Disciplines • The storage domain as a business entity • Using storage to mitigate business risk • Managing data – the foundational discipline • Management by Application (MbA) – a thematic variation • Where are the boundary lines drawn? • Wrap up and Q&A

3. 0/0 Are you creating a separate storage management group within the IT department? • Yes, been there, done that. • Yes, we’re in the process of doing that now. • We’re evaluating whether or not we should do this. • We’d like to but don’t have the resources. • No, bad idea. Cross-Tab Label

4. Fibre Channel fabric architectures Ethernet and IP Server clustering Data backup and restoration Wide- and metropolitan-area networking protocols Bridging, routing, and switching Host bus adapters and drivers Object modeling Long-term archiving Data traffic management Diagnostic and recovery technologies Enterprise management applications Database and file system architectures Security Complexity in Multiple Dimensions

5. Managing Storage • A good way to solve a complex problem: Break it down into manageable pieces. • Let’s call the manageable pieces “disciplines.” • Let’s call storage management a “practice” built on storage management “disciplines.”

6. Three Storage Management Disciplines (a proposal) • Business Management • Risk Management • Data Management

7. Storage Business Management Management of the storage domain as a business entity, complete with customers that must be kept happy, and a method for tracking and charging-back usage of capacity and services.

8. Storage Business Management (2) • Resurgence of the utility model: Did the SSPs have it right? • Do you think of them as storage users or storage customers? • Riding herd on ROI has become critical • Can you manage your customers with Service Level Agreements (SLAs)? • On-demand capacity provisioning • QoS

9. 0/0 Do you currently use SLAs for storage-related services? • Yes. • We use SLAs for broader sets of IT services. • No. • What’s an SLA? Cross-Tab Label

10. SLA Implications SLAs imply that you can: • Measure, measure, measure (“You can’t manage what you can’t measure.” Computer Measurement Group) • Identify performance problems and solve them • Forecast

11. Risk Management The use of the storage domain to mitigate corporate risk through the use of well established backup-and-recovery procedures, business continuance, disaster recovery and most recently, security functions.

12. Risk Management • Disaster recovery and business continuity • Backup and restore • Security • Compliance Are all of these purely within the storage domain? Are any of these under the purview of other corporate executives? (Examples: Corporate Security Officer, Corporate Risk Manager, Corporate Compliance Officer, Corporate Legal Counsel….)

14. Managing Risk From the Viewpoint of a Financial Risk Manager (2) Note the position of “IT System Failure” Source: Contingencies.org

15. 0/0 Does senior executive management understand the importance of IT continuance and recoverability? • Yes, they get it and give us the financial resources we need when we need them • Yes, they get it but we still have to fight for financial resources • No, they don’t get it right now, but could in the future • No, they don’t get it now and never will Cross-Tab Label

16. Data Management The management of data contained within the storage domain

17. Data Management (2) • Underpins or serves as a foundation for the other two discipline areas • Potentially encompasses databases, file systems (including distributed or global file systems) • Includes management of data copies and data migration techniques

18. 0/0 How many TB can one person manage? • 1 • 10 • 100 • This is a silly question Cross-Tab Label

19. MBA: A Thematic Variation Management By Application (MBA) • Recognizes that applications, business policies and storage are not worlds apart from one another • Starts at the application level, then works down the processing “stack” to the underlying storage environment • Help is on the way: • Applications Aware Storage (Vendor-driven R&D effort) • Applications Optimized Storage (User-driven requirement)

20. And, One Last Question… Where’s the boundary between the storage group and systems/networks/database groups?

21. Last Words • Storage users are storage customers • Risk: Its about managing exposure • MbA brings world unification
