De-Dupe volume sizes

11,003 Views

My understanding is that there are limits for the size of volumes that can be de-duped. Is that right? What are those limits and where do they come from?

Thanks!

Dave

Sorry for the confusion Andrew - my comment was dedupe on the 9XX FAS series.  It is supported on everything else obviously! 

I could be wrong on that one but that is what I was told by somebody at NetApp the other day, I haven't ever had a need to verify if the support statement is true for the 900 series.  If it isn't, please let me know!

Thanks!

Hey Andrew - About the de-dupe sizes.  It was originally a bug that was turned into a "feature" because they don't plan on fixing it.  You are spot on for the reason why.  The original bug was #254856.  Thanks!!

So....I'm horrendously late replying here....but you're right -- I didn't catch the reference to the 9xx line.

So...I'll bow to your technical superiority. (this time at least )

Hello,

Unfortunately I don't see any Information about the FAS-2040 in the "tr-3505" Document.

Can somebody tell me the dedup limit for the FAS-2040?

Thanks,

Pascal

That's a very good question. My (informed) guess is 3TB.

Here is why I think so:

The title says "Operational limits for FlexClone files and FlexClone LUNs", but if you read carefully there is also this:

"Note: The block-sharing mechanism used by FlexClone files and LUNs is also used by deduplication."

Regards,

Radek

You are correct.  I have an e-mail from NetApp stating the 2040 limit is 3TB.
