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
“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.”
— Ruettgers’ Law

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
—

—
Fast NDMP-based incremental backup

—

Save Area contains original contents of all
changed blocks
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
