VMware announced a couple of weeks ago that ESXi was being made available as a free download. There was lots of talk and discussion about what this means. Detailed price analysis have been done. On twitter I have seen several posts where people were downloading, installing, or deploying ESXi. It's twitter so you don't get a lot of detail, but it does seem to indicate that people are doing something with it.

I just wonder exactly what to do with ESXi and does it really change things dramatically.

What you get with the free ESXi download - A high performance enterprise class hypervisor with a web based management tool to create, modify, monitor, and generally do cool stuff with all the VMs that are running on that server. This is a really good deal, especially considering the price.

For a single physical server or maybe a few servers, the free ESXi should be a really great solution.

What is not included is Virtual Center and all of the features of that are multi-server related. This means that there is no VMotion, no HA, no DRS, no multi-server management of any kind.

The great thing is that it is possible to buy the correct licenses (I'll let the license experts handle exactly what this means) and then be able to enable all of these great features with Virtual Center and ESXi. So you can use ESXi as a starting point and grow into a full blown enterprise virtualization solution - later. In many ways this seems to be the same exact thing that VMware did when they made GSX Server free and renamed it to VMware Server. They even renamed ESX 3.5i to be ESXi.

There are some things that I still wonder about. Is ESXi easy enough to use for those just getting started with virtualization? Will ESXi get more SMBs to try out VMware's virtualization?
