EMC Enterprise NAS Strategy
Its 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

• 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

• 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

• The more people that access information, the
  more valuable the information.

• 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 testing environment

SnapView/IP

• SnapView/IP Save Area is created when snap is made
