The document outlines the licensing changes introduced with VMware vSphere 5, focusing on the concept of vRAM entitlements and how they affect virtualization resource allocation. It explains the implications for existing users of vSphere 4 regarding upgrade paths and compliance, and addresses frequently asked questions about licensing practices. The document emphasizes the importance of understanding vRAM pool limits and compliance requirements for virtualized environments.

29. Top 10 Q&As from the webinar

30. Q: How am I compliant with this licensing model? Is there a “hard stop” at my vRAM limit?A: To be compliant, allocated vRAMmust be equal to or less than the available pooled vRAM Entitlement. VMware vCenter Server will not impose a hard limit on consumed vRAM, but will provide alerts that consumed vRAM is approaching or has surpassed available pooled capacity.Q: If you are not RAM-constrained, is it possible to license fewer CPU's than you are using?A: No it’s required to license every single processor on your virtualized host.Top 10 Q&As

31. Top 10 Q&As Q: Is there a cost saving upgrade path from V4 to V5?A: As long as you have active Support and Subscription (SnS) there is no cost to upgrade from version 4 to version 5. If you have expired SnS then you’ll need to get that current to upgrade. Q: Does powered off virtual machines count towards the vRAMtotal?A: No powered off VMs contribute their allocated vRAM back to the overall vRAM Entitlement Pool.

32. Q: Is the new licensing model having RAM limit per processor or per core?A:In vSphere 5 there is no limit on the amount of cores per processor or the RAM a customer can install. So long as the processors are licensed and the customer stays within the vRAM Entitlement they are compliant.Q: Is vRAM counted on a per host basis, or is it the total of all vRAM across the whole cluster?A:The vRAM entitlements of vSphere CPU licenses are pooled—that is, aggregated—across all CPU licenses managed by a VMware vCenter instance (or multiple linked VMware vCenter instances) to form a total available vRAM capacity (pooled vRAMcapacity). At any given point in time, the vRAM capacity consumed by all powered-on virtual machines within a pool must be equal or lower than the pooled vRAMcapacity.Top 10 Q&As

33. Top 10 Q&As Q: What if I have multiple clusters?A: As long as the total consumed vRAMacross all virtual machines managed by a VMware vCenterinstanceor multiple linked VMware vCenter instances is less orequal to the total available vRAM, vSphere is correctly licensed.Q. How does this affect VMware View licensing?A: For VDI Implementations nothing changes for View. It will still be licensed per concurrent user. If you are using VMware for the hypervisor layer of another VDI solution, VMware has released a licensing model for vSphere for Desktops link can be found here: http://blogs.vmware.com/euc/2011/07/vsphere-desktop-licensing-overview.html

34. Top 10 Q&As Q. We are using vSphere 4 with advanced license. We can continue to use until upgrading to 5, where we will be entitled for Enterprise, correct?A: Correct, so long as you have active Support and Subscription you can upgrade to vSphere 5 Enterprise from vSphere 4 Advanced at no additional cost. Q: I read something about having to run ESXi with vSphere 5. Will I need to run ESXi or can I stay with my ESX installs?A: You’ve heard correctly. ESXi is the only hypervisor supported with vSphere 5.

35. A Final NoteIf you would like to dig deeper into the changes and how they might affect your business , we recommend that your read Understanding the vSphere5 vRAM Licensing Model, from VMware .We received several very specific questions that are not outlined in this presentation. We would be glad to answer these questions in one-on-one meetings. Please contact us at vmware@softchoice.com to book an appointment and speak with one of our representatives. Thank You
