The free ‘non-production use’ EMC Celerra VSA (virtual iSCSI appliance) is a great way to test iSCSI and SRM in a lab or evaluation environment. A few days ago EMC released a new version of the virtual appliance (18.104.22.168), based on the latest physical EMC Celerra product. You can find a complete list of all the new features, how-to guides, and other goodies here.
With this appliance you can test vMotion and SRM in your home lab, on the cheap. Great for studying for the VCP exam, or just getting experience with the advanced shared storage features of vSphere.
