Ditto. We are seeing ~65% savings on vmware luns....serving about 60 luns. no performance impacts during the day slight (~3%) when actually deduping.

Hi Bill,
we have ASIS on two of our 6070's for some time. We did only few tests but could not see any direct impact on the filers performance.
We have not yet used it for LUNs so far, but would be interessted in experience with ASIS on LUNs as well.
Regards
Jochen

To those of you that have implemented Nearstore and A-SIS on your primary storage:
Have you seen any difference in overall filer performance?
If you have LUNs, how are your space savings on those volumes?
I know that enabling Nearstore does some system tweaking in the background to increase the number of concurrent backup streams that can be running, but I don't know what else it tweaks that may adversely affect performance of a primary storage system. Afterall, it was originally designed to run as a secondary storage platform.
