EMC Enterprise NAS StrategyEMC Enterprise NAS Strategy

“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

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“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

SnapView/IPSnapView/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
