Straight from StarWindsoftware.com, mind you this is a little late, but I am sure not many people were aware, is if you are a VCP or MCP(apparently), and email email@example.com, you can get a key to activate the software. I have included an insert from the website below.
With StarWind, VMware certified professionals will get a scalable storage platform for VMware vSphere environments with advanced features at absolutely no cost. By creating networked storage with StarWind SAN software, VMware administrators get a scalable, highly cost-effective and easy-to-use iSCSI SAN that fully protects their VMware virtual machines in the event of failure. StarWind’s true active-active high availability storage architecture provides continuous and non-disruptive access to storage in the event of failure by synchronously mirroring data between two active storage appliances, or nodes, in real time with automatic failover and failback. If a disk, power or even an entire storage node fails, the redundant storage node will take over and will continue actively operating without any disruption, ensuring that storage is available and accessible on the network.
