A company is planning an upgrade from vSphere 4.x to vSphere 5. They currently have three dual CPU servers licensed for ESXi 4.1 Advanced
Each server has 256GB of RAM installed.
Their virtual machines are sized three ways.
Light. 1v CPU, 4GB RAM
Medium. 2v CPU, 8GB RAM
Heavy. 4 vCPU, 12GB RAM
The Production workload consists of.
20 Light servers
20 Medium servers
2 Heavy servers
The Development workload consists of.
10 Light servers
10 Medium servers
How will vSphere 5 licensing impact their upgrade? (Choose two.)
A.
They will need to purchase additional ESXi licenses.
B.
They will be able to reduce their power consumption.
C.
They will be restricted from powering on additional virtual machines.
D.
A license upgrade will be needed to add vCPUs to the Heavy servers.
Can someone explain this one?
This question should be pulled from current exams because vmware did away with their stupid vRAM pricing model… and that’s what this question is really all about.
4.1 Advanced -> 5.x Enterprise
5.x Enterprise = 64GB vRAM per socket
6 sockets * 64GB vRAM per socket = 384 GB vRAM entitlement
30 light * 4GB + 30 medium * 8GB + 2 heavy * 12GB = 384 GB used
Indeed, i’m trying to see the math yet am coming up short. Where is the calculation at the deems no more VM’s can be spun up?
can someone explain how does it reduce power consumption ?
Old config.============
ESXi 4.1 Advanced supporting
1 pCPU / 12 vCPU
256 RAM
From the license model description licenses 4.1 Advaced were Upgrade to 5.0 Enterprise. The new lices model from the document located at:
http://www.vmware.com/files/pdf/vsphere_pricing.pdf
you may learn that
“VMware vSphere 5 is licensed on a per-processor basis.”
So if we have 3 machines with 1pCPU on each machine there fore we do not need additional licenses for ESX. So answer A is dropped.
As the new vsphere 5.0 Enterprise model has limitations up to 32vCPU/VM. So based on that you if you not want to have more than 32vCPU on heavy server (very unlikely) you may dropped this answer too.
However I not sure why “company will be able to reduce power consumption” just from simple upgrade? Physical Server and virtual servers are just the same. Or is just overall meaning that virtualization provides power saving by consolidating servers.
I am also not sure how company will be restricted from “powering on additional virtual machines”. Based on the document described above there is no more physical resources limitation exept pCPU.
Any ideas?
Hi Xelor,
You are on the right track. The difference between 4.x and 5.x in the licensing is that the 4.x is limited to 6 cores only this means that you have to put less virtual machines than a host running 5.x which you can put 8 cores. more hosts = more power consumption. The other question I have no idea.
As the new vsphere 5.0 Enterprise model has limitations up to 32vCPU/VM. So based on that you if you not want to have more than 32vCPU on heavy server (very unlikely) you may dropp D answer too.
They will have six ESX 5.x Enterprise pCPU licenses with vRAM entitlement of 384GB (6X64GB) when upgrading from 4.1 Standard. All the vRAM will be used by the current VMs and they will not be able to start up any more.
CentimC is right. If you check the official VSphere Pricing document page 7, Figure.4 states that vSphere 4.x Advanced and Enterprise versions are entitled to vSphere 5.0 Enterprise version. From this, we can deduct 64GB vRAM and 8-way vCPU entitlements. Good luck with the rest of the calculation.
B & C are correct.
For B: there was no DPM in vSphere 4.1 Advanced, so moving to vSphere 5 Enterprise allowed for the organization to (in theory at least) reduce power consumption.
