  2. EMC Enterprise NAS Strategy It’s all about information. The way customers connect to the information is an implementation detail. EMC provides choice and flexibility in how our customers are able to access and leverage their information assets. Most important, EMC assures the ability to manage, protect, and share those information assets … because that is our business! —EMC “From our analysis we conclude that the real issue is how to best do both NAS and SAN … We have long been a proponent of consolidation of many smaller boxes into fewer, much larger footprints.” • The Clipper Group • “EMC … fastest growing NAS vendor” • IDC 10/99 • “NAS is often described as an alternative to storage area networks when, in fact, it is much more complementary … It looks like EMC is hitting the mark.” • Daniel Kunstler, JP Morgan • “The more people that access information, the more valuable the information.” • Ruettgers’ Law

  3. Publishing/broadcast Web content Rich Media Information sharing Collaboration Software development CAD/CAM Research Information Protection, Management, and Sharing Ruettger’s Law: “The more people that access information, the more valuable the information is.”

  4. NAS Business Requirements • Managing growth • File serving is mission critical and growth is out of control • Ensuring availability • Downtime causes lost revenue, market share, capitalization • Traditional solutions cannot provide the required levels of: • Availability • Scalability • Service and support • Total customer value

  5. NAS Requirements … NAS Solutions … EMC offers NAS solutions that cover the spectrum— from the midrange through the enterprise CLARiiON IP4700—For business-critical NAS requirements; reliable functionality and high availability for the midrange CelerraSE—Enterprise capabilities, rapid deployment, flexible configurations—all in one Celerra File Server—Enterprise NAS functionality built upon an enterprise information platform

  6. Advanced clustering Integrated high availability Scale by terabytes Scale to 28TB Rapid deployment Custom configuration Business continuance File level undelete CLARiiON Symmetrix Mapping Today’s Information Requirements • Availability • Scalability • Flexibility • Functionality • Architecture Implementation without limitation—the EMC Offering

  7. CLARiiON IP4700EMC MIDRANGE NAS • Midrange leading architecture—CLARiiON • No single point of failure • Proven CLARiiON architecture (more than 125,000 units) • High availability built-in • Integrated SnapView/IP technology • IP redirection • Quick reboots • Multiple filesystem support • Ease of use • 10-minute installation wizard • Web-based management • Integral part of the EMC Offering

  9. CMI SP-A SP-B Session 1 Session 2 IP-A IP-B Normal operation: Client 1 is using share from SP-A while Client 2 is using SP-B; monitor packets flow freely between IP-A and IP-B Client 1 Client 2 Network and Storage Processor Failover

  10. CMI SP-A SP-B Session 1 Session 2 Path is completed through SP-A; Client 2 continues Session 2 Client 1 Client 2 Network Failover

  11. CMI SP-A SP-B Session 1 Session 2 SP-A takes over Session 2; Client 2 will access Session 2 from SP-A after failover procedures Client 1 Client 2 Storage Processor Failover

  12. SnapView/IP • Logical copy of filesystem • Created in seconds • Separate read-only Mount Point • Supports full PITB and undo/undelete • Uses minimal space / user defined • May be used by any application, user • SnapView/IP Save Area • Created when volume is made • Basic exception list • Save Area contains original contents of all changed blocks • Fast NDMP-based incremental backup • Contains only changed blocks • Copy on first write • Multiple copies • Useful for historical views of user data • Up to 92 active snaps • Share same Save Area blocks • Self-consistent offline backup • Maintaining online backups • Point-in-time analysis/reporting • Non-disruptive testingenvironment
