Re: Send in your NetApp dedupe story and get a coveted "We Got Your Back" t-shirt from DrDedupe

I have just purchased a FAS3140 with 5 shelves of 1Tb SATA drives. We are using it as a snapvault target.

Have just set sis running against the 1,433Gb of office documents in a CIFS volume used by our document managment system. There are multiple versions of the same document in the volume. Ran a test in June 08 using our FAS3070 and the 'large' CIFS volume withover 4Tb of office docs of the same type in it. Result was 14% saving on a volume with no snapshots.

Now I are running SIS on the none deduped 'small' volume.

Have an office swipe stake were a £ lets you pick your %. Closest to correct % wins. SIS is running now and results due in a day or two. Anyone want to play?

Tell you what Brendon, when you hit 20% I'll send your entire team NetApp We Got Your Back t-shirts. But you'll need to promise to send me a picture of everyone wearing their shirts with pride...

All right so for the most part we're only running A-SIS on our VMware NFS volumes. We are seeing around 61% savings over our four datastores.

Proof is in the pudding I was really surprised how easy it was to enable on our 6030, just enabled it and kicked it off and in a few hours we were saving well over 1TB of data For 101 virtual machines on this particular cluster I am extremely happy! This definitely allows me to worry less about how much storage our VM environment is taking up, and focus more on maintaining it (and not my storage). I am also enjoying how dedup is inherited through our SnapMirror replication, that puts a lot less stress on our WAN (even though we're fibre connected between the sites, its still nice to know we're not throwing too much over it). In all, this was a zero effort way to save a significant amount of storage and defer potential storage fees! Thanks NetApp!

Was run on a FAS3140 in a aggregate made up from 12x 1Tb SATA drives. No other load on the filer as it is still in test. Noticed a CPU hit of 2 - 3% {very light}

Re: Send in your NetApp dedupe story and get a coveted "We Got Your Back" t-shirt from DrDedupe

We have implement de-dup in our NetApp FAS3070C Primary Storage and to our FAS3020 our Secondary storage (Snapvault), We do dedup on our NFS - VMWare and Xen Virtual Servers, CIFS - User Home drives, Department share drive - office documents, pdfs, htmls, manuals, installers and drivers for our development and so with Lotus Notes Database archives. It really gives us a lot of savings in space where-in we can allocate it with new requirements and increase in quota. Below are some of our dedup savings highlights.

We have not implemented dedup on high-io data, but almost all of our data in our primary storage were snapvaulted I have implemented dedup on my snapvault target, below are the results, and it is really amazing.

If you will give us shirts for all of our team, I'am very willing to send you a picture of our team wearing the dedup shirt.

Thanks and Best Regards,

A customer called that he was running out of space on his Netapp. He had a fas2020c. Asked him if he was using De-duplication. He didn't know what is was exactly.

Heard if it, but did not used it.

So i moved all simular VM's to one volume and enabled SIS on the volume, started a de-duplication job. The next morning he called and was very suprised. Het got 100 GB of free space without buying storage. got 63% on 160 gb of space ;-)

Rick that is one great story. Please enjoy your 1TB storage rebate courtesy of NetApp deduplication (actually 2TB with your replicated copy.) Go ahead and send your shirt size and mailing address to me larry.freeman@netapp.com and your prized shirt is as good as there!

Hi Antoni, thanks for sharing, and welcome to the "I saved over a TB with NetApp dedupe" club. But here's the line that caught my attention:

/vol/vol_bpdimage/ 475GB 449GB 49%

Are these image files? If so, what kind of images? We often hear from other dedupe vendors that images do not dedupe well, but I've seen otherwise in many cases.

As far as the shirts, they are as good as yours. Please send me a note larry.freeman@netapp.com and give all the shirt sizes you need and your mailing address - we look forward to posting a picture of your team on this community site.
