Red Hat Enterprise Linux, Basic (up to 2 sockets) $349
This would be used as either one standalone install of Redhat Basic on a physical server, or as one virtual machine.
Red Hat Enterprise Linux for VMware, Basic (up to 2 sockets) $594
CDW has this version for 489.99

Now here is where the headache comes in. You can only use this license on an esx host if it has 2 or less physical processers. This license would then allow you to create 4 virtual machines licensed with Redhat Basic. From the documentation:
"Basic subscription ( 1 year ) - 1 system, up to 2 sockets, 4 guests"
So this means
Basic subscribtion. 1 year license, for one VMware ESX server which gives you 4 virtual machines.
If you wanted to license 16 RedHat basic virtual machines on your esx host, you would need to buy 4 of these subscriptions.
In our case, we have 4 ESX servers and each have 4 physical processers. This is what forced us into the Red Hat Enterprise Linux Advanced Platform for VMware license. Redhat allows you to pool these licenses if you have an esx cluster. We wanted ~60 licenses, and the Advanced Platform allows for 10 RH VMs per license. To cover our need, we had to order 10 of these licenses.
>"I don't see where they say on the website per system vs per server. Your blog seems to imply that the second $594 is unlimited Basic installs on one ESX server?"
Yeah, Redhat almost seems like they are trying to hide the availability of this product line. If you need prices, check CDWs website. I searched for hours and found almost no documentation on RedHats site.
>"We have 2 socket ESX servers with quite a few RHEL VMs. This could definitely be helpful but am I following you? How does that work with VMotion?"
As long as you hold the correct number of licenses to cover the RH VMs, pooling is allowed and you will be fine. All RH VMs could migrate all of the VMs to one host and would not have a problem.
Just an FYI, we did go with this licensing and we did save a lot of money. Keep in mind though that you can do the RH basic license since the servers are 2cpu, but there is a downfall. If you do only basic, then the support contract for basic would apply. I think that's something like Mon-Fri 24 response time for support. So if there are critical systems that you might need immediate 24hr support on, talk with a RedHat rep or CDW. You might wind up needing to get a mix. Something like X number of basics, and one advanced license for the critical systems. Does that make sense? Let me know if you have any other questions.
