I had read up couples of review from the expert which provide some useful information for reference purpose.

VMETC

Virtualization Review

Both articles talk a little bit Nehalem. Personally, I will be very excited to take a test on this and perform the test comparison within the current quad core. VMETC did mention as it will able to support up to 21 VMs per core, and this is a real amazing number to be achieved.  Nehalem quad core will able to replace 9 single core xeon processors with 20 % energy saving.  This will boost up the CPU performance and reduce the power consumption.

Personally, I think the number of Vcpu per ESX servers is too minimal. Imagine if we do run a servers with 4 or 8 physical CPU sockets and we consolidate 40 : 1 Physical server in our virtualization environment, we will hit to the bottleneck on maximum numbers of Vcpu per ESX servers but not due to the CPU consumption.I hope VMWare should revise the configuration to greater number or 256 Vcpu per ESX servers.

The reason of virtualizing today, is really not about sacrifice performance. In our environment, we have most VMs running with 4 Vcpu as the result of customer compare VM to Physical Servers to ensure the performance is sustainable or improve when they switch to VM. When the VM itself is idle or less busy, it will not consume too much resources on the Physical CPU cores. Next release of ESX will go for 8Vcpu per VM. The number of Vcpu been assigned to the VMs which require extra CPU resources will increase too.

Updated: Configuration Maximums for VMware Infrastructure 3 – Number of Virtual CPU = 192

Most of the time, we may still not 100% utilize the servers capacity due to some consideration of High Availability and Performance issues.

Here I am interesting to show 1 of the screen shot I capture during my stress test on the ESX host for our production machine which hit to 100% of the CPU  utilization on the ESX host level.

This will be really amazing if we can keep this kind of utilization without impact to the performance for the VM guests. Unfortunately, it does slow down the VM guests in my case as many of us know that we shouldn’t keep the ESX servers resource utilization actively more than 90%. In this round of test, I manage to achieve 40 : 1 ESX host consolidation at my ESX Servers. The normal day, we will always have 28 : 1 as minimal.

Price cut from Intel and 6 cores cpu will definately increase the consolidation ratio in our case moving forward. The integration with the latest technology and ESX 4 will really help in the case to achieve higher number consolidation ratio moving forward.

For more information, please refer to the link below

Information Week – Intel slash processor price

In this economy situation, this is really helpful. For my personal experience, we always experience price increase significantly when we choose the upgrade of processor spec from 2.6Ghz to 3.0Ghz. The new pricing will allow the vendor to revise their current servers pricing and helpful for us who need powerful chips to support the virtualization environment. I am really waiting the price cuts from the vendor in my negotiation for my additional ESX servers that I plan.

As current agreement, it will maximum allow 4 cores per CPU sockets. Down the road, it will be 6 cores and 8 cores per CPU. They might be a chances of VMware to change their CPU licensing model in the future, or they may stick with the current policy which base on the physical CPU sockets. VMware is the best products at the current Virtualization market, but they do need to understand that the TCO for a users to start the Virtual Infrastructure Enterprise is more or double the price of the potential customer to switch for Xen, Citrix or Hyper-V. Personally,

I do hope the Licensing Module will be remain and VMware may need to consider to reduce the licensing or provide additional software or services to be bundle together. Let’s keep an eye on this and soon will have some announcement on this by VMware.
