[BBLISA] 10+ TB RAID experiences?

[Arthur Gaer]

My understanding--from a few years ago--was that NetApp's filesystem  
snapshot facility was something of a side-effect of NetApp's  
propriety WAFL file system/implementation and that it would be quite  
difficult for another filesystem to provide the same types of snapshots.

Perhaps the technology of other vendors/filesystems has changed in  
the intervening years, however.
