It’s extremely cool, and extremely valuable to the business. You’ll have to make your own decision as to whether the cost of VI3 Enterprise is worth it to the organization. Personally, I think that the functionality you get in the VI3 Enterprise bundle–which includes HA, DRS, VMotion, etc.–is more than worth it. Is it worth having your workloads dynamically load balanced across all available physical hosts? Is it worth not having downtime due to a physical host failure, like I described above? Is it worth being able to move workloads from host to host on demand with no downtime? Again, that’s a decision you’ll need to make for yourself and your own organization.
