Netapp vs EMC storage

Hello,

What is the main differences between EMC products and NetAPP products? I know it is depends on the product. I mean overall what are the differences in technology?

depends which EMC product you're comparing to Netapp.

Netapp has something that nobody has which is WAFL filesystem. If you need solution that can serve tens of millions files from a filesystem  - then netapp is the only option you pretty much have, unless you find a workaround (storing files in a database or blobs or something like that).

WAFL is basically ZFS if you look at it under the hood..which is why Netapp was suing Sun for years on that patent

paul: true but ZFS on UNIX server will not be able to handle as many files as netapp WAFL, because OS will choke on amount of metadata needed to be cached on top of ZFS or any other filesystem (i e ZFS itself is not the problem here).
netapp handles that more efficiently and has optional hardware memory board for metadata caching when needed but even without that it can handle much more than ZFS on linux for example (tested).

With the courtcase over it's a matter of time.  I'm a NCDA so I do mostly Netapp but have seen some decent size ZFS rollouts.  Some SAN vendor will pick up and roll with it shortly.
