  1. Building the Enterprise Storage Utility Scott Gready Business Development Mgr. Enterprise Storage Software Compaq Computer Corporation November 3, 1999

  2. Enterprise Network Storage Vision Storage is a utility service to the enterprise

  3. Compaq ENSA:Strategic approach • Drive and leverage industry standards • Integrate our enterprise computing capabilities with the benefits of centralized storage management • Deliver an open solution, with heterogeneous support at each level • Achieve the highest degree of performance, availability, scalability and flexibility... • at the lowest total cost

  4. Storage Virtualization

  5. Dynamic Scalability • Storage allocated from a single common pool • Scales online from gigabytes to petabytes and beyond • Capacity easily acquired and added to the pool as needed

  6. Simplified Management • Centralized management of distributed resources • Unified management of primary and secondary storage • Policy-based management • dynamic allocation • automatic redeployment • intelligent data replication and protection • performance balancing

  7. Data Replication • Instant, continuous replication of data • Rapid user-initiated restores • Enables quick and easy backup

  8. SAN Efficiencies • SANs are driving new Storage efficiencies through “networking” • Storage Consolidation • Improved Manageability • Improved capacity utilization • Rapid resource redeployment ... to provide a lower Total Cost of Ownership • SANs also introduce “network” complexities that must be addressed • Interoperability • Security • Availability/Fault Tolerance

  9. The ideal SAN • Provides the inherent value of network storage with almost unlimited scalability • … while maintaining the performance levels of today’s SCSI products • … while leveraging existing storage investments • … while addressing key enterprise issues required for any viable network • Security • Data Integrity

  10. SAN Scaling Into the Future Utility Pool Fabric Cluster Very Large SANs 10,000+ nodes Integrated Large SANs ~1,000 nodes SAN ~100 nodes External Arrays ~10 nodes Today Host embedded Storage

  11. RA8000 SCSI or FC ESA12000 FC-AL or FC Fabric Compaq ENSA:StorageWorks into the Future Future Shipping Today Open SANs Data Replication Manager Virtual Replicator Heterogeneous SANs Homogeneous SANs RA 3000/ RA 4000 Smart Array 4200 Investment Protection

  12. OpenSAN Standards • Compaq driving for the OpenSAN • Heterogeneous Host/OS • Heterogeneous Storage • Driving SNIA to be the storage standards body, focusing on: • Management • Security • Interoperability

  13. SAN Appliances • The rationale for SAN Appliances can be found in today’s networks (Routers, Domain Servers, etc) • As SANs grow, it becomes too complex for each node to have all “context” • SAN Appliances provide a scalable way to distribute SAN infrastructure and value-add functionality • Management • Fault / Configuration Management • Performance Management • Capacity Planning / Accounting • Asset Management • License Management • Security • Storage applications, such as NAS

  14. SAN Appliance ExampleSecurity for the Storage Utility Authentication Nodes • Policy enforcement • Password protection • Provide the “access map” “Authentication Server”SAN Appliances

  15. Adding an element to the Utility • New Elements “zoned” to talk to authentication servers only • Authentication servers: • Review new element’s features • Check for compatibility • Availability verification • Apply user defined policies • Provide “maps” to effected storage/servers • Provide keys (if required) • Introduce element into SAN (management tools) New Element

  16. StorageCluster Virtualizes Data Location and Placement • Based on Compaq’s Open SAN approach • Can Virtualize, Manage, and allocate all SAN Storage • Is OS and File System independent but can support any level of clustering and data sharing desired • Can coexist with Non-virtual storage on same SAN • Is Storage System AND host independent • Does not effect use of existing value-added storage features Compaq Confidential

  17. Storage ClusterSAN Virtual Storage VirtualDisk 3 VirtualDisk 1 VirtualDisk 1 VirtualDisk 2 Host Host Host • Virtual Volumes can span arrays • Data can be moved without interruption • Data can be “placed” based on characteristics required (policy) SAN Appliance FC-SW Fabric Array Array Array Array Compaq Confidential

  18. What Makes Compaq ENSA Different? • Compaq vision is consistent with industry and market direction • Compaq implementation and value proposition are more comprehensive than other initiatives • industry standards and a leveraged partner model form the foundation • architecture is open and inclusive • architecture is DISTRIBUTED not MONOLITHIC • approach is practical and pragmatic • all types and styles of storage solutions are encompassed
