Some SIS Questions

[gmail2]

Hi all

I'm considering enableing Single Instance Storage on our mail file server as I know for a fact there are alot of duplicate files on there. But I have a few questions that I'm hoping somebody can help me out with:

1. Is there any way to calculate the savings before I enable it ? Eg, run a sis_groveller.exe download which would tell me all the duplicate files it finds ?

2. Are there any risks or gotchas that I should be aware of before enabling SIS ?

3. If I have two R2 servers which have the same DFS shares and folders, is it OK to have SIS enabled on one but not on the other ? Or should I enable on both ?

I have to say, on the box, SIS sounds quiet good. But I don't know how many people are using it on their file servers and I can't seem to find much on it other than the standard MS documentation. Would apprecaite any advice

What mail system are you using, and does it support SIS?

oops ... sorry, that was meant to say MAIN file server, not mail file server It's a 2003 R2 file server, not exchange

If it isn't Windows Storage Server 2003 R2 or Windows Unified Storage Server then SIS is not available ...
