It works well enough, and once you run OnTap 8.1 you no longer have a 16TB/volume hard limit. The one Gotcha! is that dedup only works up to the maximum logical volume size. If the hardware supports say 50TB for the maximum, and your dedup ratio is good it will stop doing dedup once the size of the volume without dedup hits 50TB even if there is more stuff that it could dedup. This caused all sorts of headaches for me as I had to move primaries to different volumes on the NetApp as space started disappearing at a much faster rate. _______________________________________________ Discuss mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
