        Having this said running 3 CPU's with ESX will run just fine so don't worry about this.

         

        Absolutely true - but do keep in mind that you will be consuming 4 CPUs worth of ESX licenses, that will drive your cost up, too. I agree w/Massimo that the 3 CPU configuration is for those corner applications that have very specific demands. As with any benchmark test, it's important to read more than just the headline

         

        In my opinion, you'll (Paolo) come out ahead by populating your servers with the four CPUs it supports. If your environment is like most, the future cost of purchasing a single CPU (much more than if you buy it when you buy your system) plus the cost of opening the box to install it (labor, scheduled down time, etc.), it won't be practical to add the fourth CPU later.

          Ken, I will not waste license, the new model permits to use 3 x 2-socket license as Massimo said above.

           

          Yes, adding the 4th CPU will have some  (or more) additional costs. These two 3 CPU server comes from a little analisys in wich 2 CPU were not enough and 4 too expensive.

           

          For the moment my customer agreed to my proposal, so in 20 days or less I will start the project! I hope not to have troubles with this......

            Ken,

             

            assuming you have an even number of sockets in total (2 x 3 CPU's = 6 for example) I assume VC will be able to serve the proper number of socket licenses ...... (3 sockets times 2). Or are you saying it will only "distributed" an even number of socket licenses ? (2 - 4 - 6 - 8 - ect etc)

             

            Never thought about this really ......

             

            Massimo.

              Well, since I've never played with an odd number of active sockets, I can't say for sure. I assume (I know, I know...) that licenses are served in two-socket increments. That's how you have to purchase them...

               

              I guess we'll find out for sure in about 20 days

                Yes guys,

                 

                more than 20 days are passed. There were some problems in the supply chain!

                 

                But now it is official. 3 Socket consume only 3 License.

                 

                It has been tested on a x3755 with 3 dual core CPU, with esx 3.0.1 and VC 2.0.1

                 

                So, no license wasting in this case

                  What do you mean? Say you have loaded 8 x 2-socket licenses in VC (i.e. a total of 16-socket). What happens when you connect the first 3-socket server? Those 16 gets to 13 ? And then to 10 when you connect the second 3-socket ?

                    Massimo,

                     

                    I have  3   2-socket Enterprise License loaded on lic server, so a total of 6 CPU (sockets) appear on Virtual center.

                     

                    The first 3-CPU node joined to virtual center use 3 License. The remaining 3 are for the second node, with 3 CPU.

                      Well color me pink! Interesting, but I don't think I'll ever take advantage of that, unless we come up with some reason to use a server with a single CPU populated...

                       

                      Thanks for letting us know the outcome of your testing

                        Ken, I agree with you. It is a really strange configuration, but I was able to start a new virtualization project where costs were very important.

                         

                        x3755 permitted to use 3 CPU and licensing was reduced to 3 2-socket.

                         

                        I made some projects with 30/60 virtualized servers but here in Italy a lot of my customers have 5/10 Physical server...I think about this project as a victory! Mine, of IBM x3755, and Vmware of course!

                          I'll ever take advantage of that, unless we come up

                          with some reason to use a server with a single CPU

                          populated...

                           

                          I've been using 1 cpu servers for demo purposes,

                          only one cpu license taken from the license server.

                          It was even HP gear...
