The Nasuni Filer running as a VM treats local storage as a big (64GB or greater) cache. Then on an hourly basis replicates changes to that cache to the cloud provider of your choice. The intent being that your active data is stored locally on the cache and ALL your data (inactive & active) is in the cloud. When you need an older file it is automatically recalled. The provider you choose can be one of several. In our case we selected Iron Mountain, they are a client of Storage Switzerland, and we like their architecture as discussed in the Case Study we did with them and Nasuni.

- Initial Configuration

Our initial configuration has the Nasuni Filer running on our primary virtualization host, a  dual core Mac with 16GB of RAM running VMware Fusion connected to the rest of our lab via 1GbE to our Netgear Prosafe GSM 7224. As you can see from the video below installation was incredibly simple, possibly the simplest NAS installation we have ever performed. Double clicking on the VMX file started the installation process and after providing the IP address, the filer was up and running and has not been down since.

The system starts out in a public sharing mode. As you can see from the screen shot it is immediately available to other systems on the network. While Nasuni only officially supports windows clients we have had no issue thus far with either Linux or Macintosh clients. Although if you use either of those platforms with the product you do so at your own risk until they are formally supported. Don’t get mad at the Nasuni guys and especially don’t tell them that Storage Switzerland said it would work.


We like the fact that the NAS came up in a public mode, the first thing we like to do with a new NAS when it comes into the lab, as you can see in the video, is copy something to it. However with that initial test out of the way its time to lock things down. Being a Macintosh user I am a bit of a GUI design stickler and I am pleased to say that the Nasuni GUI does not disappoint. It is clean, uncluttered and very easy to navigate to where you need to go.

From the opening screen we were able to navigate to two key areas quickly. First was to lock down the configuration by setting user names and passwords and the second was to set bandwidth throttling when replicating to the cloud.


Also in this version of the open screen you can see that we have been adding data to the device incrementally and that the device takes snapshots as we add that data to it. Those snapshots are then replicated to the cloud.

In our next entry we will take a more detailed tour of the GUI as well as update you on our general impressions. The key takeaways thus far are it was a very easy installation, easy configuration and excellent initial performance. Most importantly integration to cloud storage that is so seamless that it barley gets mentioned in our initial write up. Which is how it should be, cloud storage is something that should just work and Nasuni makes that happen.
