Isilon IQ and S series rocks
Just finished about a month of resiliency and performance testing of the Isilon OneFS-based clustered storage. In our lab we had six IQ9000 nodes, six 5400S nodes and an accelerator node with dual 10Gbit interfaces. I tested NFS, CIFS, FTP, HTTP, and even got a hold of their beta code to test iSCSI. While I can’t share any benchmarks (NDA) I have to say, their gear is awesome. It’s super-bulletproof. You can powerfail drives, nodes, or the back-end Infiniband switches and the thing just keeps on rocking. The selectable parity can even allow you to take more than one node failure and keep trucking along.
The GUI is not a huge DHTML crap-infested monstrosity like some I could mention (ahem rhymes with Gun – as in what you want when you use it). It gets the job done, shows you the stats you really would care about like “How full is my cluster in total?” or “How much traffic am I seeing to all nodes?” etc.. The command line is also very functional. Most of the commands start with ‘isi’ like “isi stat” that will show you the cluster status.
One rather dramatic display of simplicity is when you setup a new node. You just connect it to the infiniband and within two keystrokes on the node’s front panel you have the new node join the cluster. The cluster expands the space available and get’s you going right away.
