2. Storage Area Networks (SAN’s) • What Is A SAN ? • What Is The Justification ? • Why Is Fiber Recommended ? • Why Is It Needed ?

3. Storage Area Networks (SAN’s)

4. Storage Area Networks (SAN’s) • SAN Consists Of Connections, Hardware & Software. • Dedicated Entirely To Storage. • Uses Fast Fibre Interconnect Technology.

5. Storage Area Networks (SAN’s) • Obvious Dramatically Better Results In Data Sharing, Consolidation, Accessibility Management, & Security Of Enterprise Resources. • SANS Give Better Than 20% Average Increase In Storage Utilization Rate.

6. Storage Area Networks (SAN’s) • SANs Can Allow For A Better Than 50% Reduction In Tape Utilization. • SAN’s Allow For A Major Increase In Storage Productivity. • SAN’s Give Better Access To Remote Mirrors & On-line Backups.

8. SAN Concepts Storage Array

9. Storage Area Networks (SAN’s) • Data Replication Manager (DRM) • Allows Real-time Copy Of Data On-line To Local Or Remote Locations • Data Replication Performed At Controller Subsystem Level Without Affecting Host Activity. • DRM Works On Fibre Channel RA8000 and ESA12000.

10. Storage Area Networks (SAN’s) • Using Data Replication Manager • When The Cost Of Unavailable Systems & Data Loss Over Shadows The Cost Of Duplication Of Systems. • A Need To Recover From An Outage In A Very Short Time Exists. • Business Continuation Necessity. • Estimate Downtime Costs Between $15K To $6.5M Per Hour !

12. Now, let’s talk about... High Availability!

13. How much availability do you really need? Uptime Levels (%) Annual Downtime Availability Classification Fault Tolerant 99.9999 < 1 minute Extremely High Availability 99.999 5 minutes Fault Resilient Clusters 99.99 53 minutes with Failover High Availability 99.9 8.8 hours Commercial Availability 99.5 43.8 hours Sources: Gartner Group, Transaction Processing Performance Council, Compaq

14. Average Cost per Hour of Downtime Industry Application Cost of Downtime Financial Brokerage operations ??????? $ 6,500,000 Financial Credit Card Sales ??????? $ 2,600,000 Media Pay Per View ??????? $ 150,000 Retail Home Shopping (TV) ??????? $ 113,000 Retail Catalog Sales ??????? $ 90,000 Transportation Airline Reservations ??????? $ 89,500 Source: Gartner Group and Contingency Planning Research

15. Backup Issues • Backup becomes difficult because • Storage capacities are increasing faster than customers have planned. • On-line applications require no “unavailability” time due to 24x7 operations • Product costs are far less than management costs and “unavailability” costs • Performance is hard to model because components work serially and the • solution is only as good as the slowest component • Customers realize their “true risks & costs” only when a restoration is needed • No tape standards exist and there is no single ISV that supports all operating systems

16. Traditional Backup Methods Network Backup Direct Backup Many Drives or Libraries Drive or Library Benefits: • High Performance Rates Drawbacks: • Maximum Hardware/software • No Centralized Administration • No Broad Connectivity Benefits: • Minimal Hardware/software • Centralized Administration • Broad Connectivity Drawbacks: • Network can be very slow

17. Digitask’sAlternativeEnterprise Backup Solution -FibreChannel Backup & Restore • Puts Tape storage on a high-speed, independent Fibre Channel (100MB/sec) dedicated data backbone • Leverages current high performance DLT and Library technology including scalable Compaq DLT Mini-Library model • Provides a centralized, automated backup solution for multiple servers • Offers greater performance with less hardware than traditional LAN-based data management • Eliminates data traffic associated with a network backup • Functions with standard backup software if needed

18. Storage Area Networks (SAN’s) • Data Replication Manager (DRM) Features • No Single Point Of Failure (NSPOF). • Host Independent Copy Operation. • Data Protection Over 10KM to 40KM. • Fibre Channel Data Xfers At 100MB/sec. • Supports RAID Configurations (0,1,0+1,3/5). • Bi-directional Remote Copy.

19. Storage Area Networks (DRM)

20. Multi-Site SAN With EBS & DRM

21. SANworks Strategy • Open SAN accessibility • Storage virtualization • Enable flexible storage pooling for unprecedented scalability, granularity, availability, and serviceability • Data protection and replication for fast recovery • Replace traditional backups with virtual snapshots and physical clones that can be recovered quickly • Make distance transparent to remote replication

22. Enterprise Backup & Virtual Replicator (WNT & Win 2000)

23. Next Step in the ENSA Evolution: Open SANs Shipping Today Open SANs The Next Step Heterogeneous SANs Homogeneous SANs

24. Cluster Storage Server(Network Attached Storage)

25. Wide Area Cluster Concepts • Definition of Wide Area Cluster (WAC) • Some Nodes Separated from Others • Implies Separate Computer Facility • Distance Varies

26. Types Of WAC • Remote Cluster Node • Multi-site Cluster • Disaster Tolerant Cluster • Duplication Of Hardware

27. Wide Area Cluster
