VMware – Free VMware Certified Associate (VCA) exam vouchers for a limited time

Free certification information

For a limited time only, you will be able to get free VMware Certified Associate (VCA) exam vouchers and get certified by taking the exams from the comfort of your own home.

Update 06-12-2012 : Rasmus Haslund added a new method: http://www.perfectcloud.org/certification/vmware-vca-exam-experience-plus-free-exam-voucher/

Update 24-11-2013 : Rasmus Haslund provided a new code on his site : http://www.perfectcloud.org/certification/vmware-vca-exam-experience-plus-free-exam-voucher/
Give code VMRT9B503121 a try.

Update 22-11-2013 : Apparently the codes are not working anymore, see the comments. You could give code VMRT1B01791B a try.

Update 19-10-2013 : Apparently Global Knowledge provides a code as well. Can be used until January 31st: http://www.globalknowledge.com/training/generic.asp?pageid=3596

Update 09-11-2013 : Eric Sloof from ntpro.nl provides a code as well. Can be used until January 31st: http://www.ntpro.nl/blog/archives/2471-Free-VMware-Certified-Associate-Certification-Extended.html

The currently available tracks which you can do for free are:

VMware Certified Associate – Datacenter Virtualization (VCA-DCV) – Exam blueprint
VMware Certified Associate – Cloud (VCA-Cloud) – Exam blueprint
VMware Certified Associate – Workforce Mobility (VCA-WM) – Exam blueprint

Free online e-learning modules are available that take about 4-5 hours to complete and that are sufficient to pass the exam. The registration process is a bit cumbersome in my opinion, but this blog post contains some instructions to help you with that.

From what I can see, this offer is valid until the end of October, but I might be wrong so it’s best to take the exams as soon as possible. I also think you’ll also be able to use the same voucher code to re-take the exam should you fail, but again I’m not really sure. Once I have more information, I will update this blog post.

Future additions

In the future a new track VMware Certified Associate – Network Virtualization (VCA-NV) will become available. It is not clear when it will arrive and if you’ll be able to use the voucher on this exam as well, but using the link you can at least have VMware notify you when it becomes available.

Usefulness

I think these free e-learnings are a good way to become familiar on a high level with VMware products, terminology and use cases. The VCA certification is proof you have this knowledge and might give you an advantage.

Being able to certify for free now can come in handy for:

  • People that are still studying.
  • People that are in between jobs.
  • People that are working in other parts of the ICT that are interested in VMware, but cannot get their employer to pay for VMware training/certification.
  • People and companies that want to stimulate certification, but also have to save costs.
  • People that are interested in virtualization and are considering doing more with it, but don’t know yet if it’s something for them.

There are of course more possible situations, but I think these are very common.

Thanks

Thanks to VMware for making this possible and Rasmus Haslund (@Haslund) for sharing the information and the voucher on his website http://www.perfectcloud.org, If you decide to use this offer, please also leave a comment at his website.

Also, as always … sharing is caring, so share this with others.

VMware – PowerShell script to get (storage)vmotion history

Even though I’ve always liked VMWare vSphere, I thought the events and informational messages weren’t always as helpful as they could be.

One of the common things I want to know are the vmotions and storage vmotions that have taken place. Luc Dekens has created a great script that shows the (s)vmotions that have taken place including details about them.

Be sure to take a look at his website for the PowerShell / PowerCLI script including a detailed explanation:

Intel Haswell CPU available in June with VMCS shadowing – nested virtualization

In the beginning of June, the new Intel Haswell CPUs will be available. Besides the regular improvements like being faster, having better energy efficiency and having better graphics capabilities, these new CPUs will also include VMCS shadowing (Virtual Machine Control Structure Shadowing).

Basically it’s a feature that allows you to run a hypervisor (like VMware, Hyper-V, Xen Server) and create another hypervisor as a VM beneath it. This is also called nested virtualization.

Some of you might say, “Hey this is not new, I’ve already done this with VMware!”. The difference however is that the current method uses some sort of emulation that does not directly access the hardware. And even though it’s great for testing purposes, the performance is suboptimal.

With the embedded hardware supported VMCS shadowing in the new Intel Haswell CPU the nested hypervisor can directly access the hardware, which should improve performance. Also, it might even make it possible to use non-VMware hypervisors in a nested virtualization scenario.

Of course as always, we’ll just have to wait and see how the performance will be in real-life. It’s also not clear to me yet if hypervisors need to be updated to be able to leverage this option. Nonetheless, to me it sounds very promising and I look forward to playing around with it.

For more information read this great article by Gabe Knuth called “Could VMCS Shadowing (a.k.a. nested VMs) from Intel’s new Haswell processors be what Bromium needs to work in VMs?”. When you use the links in the article you will be able to get more information about the Intel Haswell CPUs including benchmarks and more detailed information about VMCS shadowing and use cases.

[EDIT 08-06-2013] Citrix is working hard on integrating VMCS Shadowing / Nested VMs in their products:
http://blogs.citrix.com/2013/06/03/intel-and-citrix-collaboration-to-bring-support-for-hardware-accelerated-nesting-of-hypervisors-into-market/#comments

If you’re planning to build / buy an Intel Haswell based computer or Home Lab, be sure to look into the confirmed USB3 bug in the chipset. Also unfortunately the DDR3 prices have increased substantially (almost 50%) over the last half year.

VMware – Free videos covering what’s new in VMware vSphere 5.1

In the last half year, it’s been a very busy time for me because of all the new Microsoft products being released. As a result of this, I unfortunately haven’t been able to look into the newly added features and capabilities in VMware vSphere 5.1

Luckily however, VMware has released these free videos covering what’s new in VMware vSphere 5.1. This should make it easier to get up-to-date again.

I hope you enjoy it.
