        I expect to start looking at XENServer as there is no need to purchase MS licences and they have a good blend of features across their releases, but as a medium term solution as my current 4.1 licences will keep me going for a good year or so.

         

         

        The new limit seems just a bit daft as it means I have more memory allocated to my VMWARE Workstation environment than I will be allowed to allocate to a 'VMware vSphere Hypervisor' system!

          I was thinking of that too. I am having 16 GB of RAM in this PC running Windows 7 and VMware Workstation, really strange that it should scale better than the free Hypervisor.

           

          I wonder what the reason for this could be. When Microsoft has the free Hyper-V version based on Server Core available for small business companies, it is somewhat unlogical for VMware to make the VMware product unavailable.

            8GB vRAM max for freeware ESXi?

            I'm shocked...

             

            Little question: 8GB vRAM max. per CPU or per physical server?

              That will be 8GB per physical server, but there does not seem to be a limit on the number of CPUs

                No, definitively it is 8 GByte per virtual machine, not per ESXi host.

                It has a socket/core limitation, but I was unable to find the number quickly. I am running a two socket, four core each machine.

                  Where did you find the information about the 8 GB vRAM limit?

                   

                  In this chart, which is for vSphere Hypervisor 5, it says that a virtual machine could use 1 TB of RAM.

                   

                  See the bottom:

                   

                  http://www.vmware.com/products/vsphere-hypervisor/compare.html

                   

                  However, there are errors in the chart, for example claims that Storage vMotion and Storage DRS would work, but clearly not since they are vCenter technologies.

                   

                  This also seems a bit strange:

                   

                  "Ability to reclaim unused memory, de-duplicate memory pages, compress memory pages" .. great features of course, but not much use if the total configured memory limit is 8 GB.

                    Are you thinking of 4.1 rather than the new 5.0 release?

                     

                    No that is 8Gbytes of vRAM as stated at the end of this page

                     

                       http://www.vmware.com/products/vsphere-hypervisor/faq.html

                     

                    vRAM is the entitlement of pooled virtual memory used across all active virtual machines on the system (or that is how it is at least defined on the other versions of ESX 5.0).

                      One of the two tabs next to each other is wrong then. The FAQ tabs says 8 GB vRAM total and the Compare tab claims 1 TB/vm. Which is correct?

                        Yes, I am thinking of 4.1 and I would be greatly disapointed, if VMware would lower the limits. There is already a growing market of other solutions.

                          The 1TB/vm is the maximum amount that the VSphere 'engine' can now manage if you have the correct licensing in place. While the 8GB is the limit set within the licensing terms of the free edition of the hypervisor. The 8GB limit may not be enforced but if you go beyond it you break the T&Cs.

                            But the chart is to compare the free vSphere Hypervisor against Microsoft and Citrix. Since there is no license you could not have a "correct licensing"?

                             

                            If the 8 GB vRAM is correct than the claim on the compare tab is a lie. If we look at the competitors in the chart we see that Hyper-V "only" has 64 GB/vm and Citrix 32 GB/vm.

                              Hopefully there is a typo on that FAQ page like there were on the VSA presentation - support for RAID5.

                               

                              I hope that the listed entitlement is per CPU. 8GB per CPU would not be that bad.

                               

                              All the other vRAM entitlement that I see listed are per CPU.

                                Well it would still be very low. The kind of environment that would run vSphere Hypervisor would be very small customers and not likely multiple CPU sockets in these hosts.

                                 

                                If a CPU now could host 8 to 12 cores then it would be quite a waste to install several physical processors but still only use 16 GB of RAM for the virtual machines.

                                  I agree that it is still low (very low), but would be better than a hard entitlement of 8GB.  I currently have 3 ESXi 4 hypervisors running sparse dev environments (to prove the technology of course).  They are loaded with over 32 GB RAM and utilizing 90%.  So out the box with vSphere 5 Hypervisor I would be past my entitlement vRAM.

                                   

                                  I think this is an effort to push us to purchase licenses for the hypervisor.  They know that lots of people are running it in a production environment and they are loosing money on it.  After all their plan for releasing it was to "[enable] IT professionals to become familiar with the technology and prove its value in their own companies."

                                   

                                  I am not compelled to upgrade to hypervisor 5 for our dev environment. I will not have enough resource to prove the technology behind vSphere hypervisor 5.0...

                                   

                                  Lets hope they fix this.

                                    Item 2 is a bit of a joke, how many people use ESXi with only 8GByte of RAM!

                                    It's a rather poor joke at that. I'm only running 7 virtual servers on my current ESXi 4.1 host, but I'm using 10-12GB of RAM (16GB in the host)... I'm looking to increase the host memory (or add another host) so that I can run more VM's and/or have HA.

                                     

                                    Is that 8GB per socket/CPU or total?? IF per CPU/socket, then it's not as bad. It's still a bad joke, but it's not too hard to get around (and have a decent amount of VM's running in a home lab)...
