storage savings with dedupe on Netapp FAS2020 vs EMC NX4
I am looking to see if anyone has experience with these 2 SANs and see what their experiences are with deduplication.
I am setting up a virtual environment that will have 7 virtual servers running on it. It will be using NFS for the VMs. The main server is a mail server with 100 users. There will also be a domain controller, print server, 2 database servers (they are small and only have 2 users on each, so small IO), a internal web server for 50 users with small usage, and a test server. This environment does not have a high load altogether. Due to this I am looking to use dedupe on the production VMs and see how it impacts the performance.
However I am wondering what kind of savings I might see with the different options. I know that NetApp will dedupe on a block level so I would expect to save a good amount of space with the multiple OS's and also in the mail since there will be a lot of duplicated emails and attachments. I am not as familiar with the savings that I will be getting with EMC. First I am assuming that the file level deduplication will not have any affect on the duplicate files in the VMs since it is within a VmDK file.Also I believe that I will not see any compression of the VMDK files? I read on one site where someone tested a similar setup and realized no compression with the VMDKs. Anyone have any ideas if this has changed?
From what I have seen it looks like NetApp will realize a much better space savings in this setup. Does anyone disagree with this and why?
