NetApp has also produced a Data ONTAP Simulator which in their words is a “A tool that gives you the experience of administering and using a NetApp storage system with all the features of Data ONTAP at your disposal.” This is hugely significant as it means if you know how to administer and configure the smallest FAS2000 Series Filers you are pretty much up to speed to administer and configure Filers up to their biggest and beefiest FAS6200 Series Filers so you don’t have to learn another management interface when you upgrade.
One of the strengths of NetApp’s storage offering is that its controller operating system called Data ONTAP is the same across every NetApp Filer storage product they sell. UPDATE 7 September 2012: NetApp has released its Virtual Storage Appliance, Data ONTAP Edge which is a licensed functional VSA.
