VCP4 Certified !!!


Yesterday I took the VCP410 exam and I’d like to share some of my experience.

First, here’s a personal guide I built for my self with the topics I have studied, may be it would not make sense for you, but it’s a start.

Another tip is to gain experience working with the environment, I know it’s not easy, may be your company does not have VMWARE yet, but it helps a lot.

Build your own LAB environment, there are several HOW-TO on the intenet about how to do that. It will allow you to test things, configure , troubleshoot, etc..

Be careful with DUMPs, I looked at a few ones, there are some wrong answers, others mix question about ESX 3.5 with ESX 4.0, so instead of memorizing it, try to duplicate the configuration on your LAB.


About the exam:
- I’ve seen a lot concern about maximum configuration and we should memorize them. So I did, in fact it was my main focus during study, but, lucky or not, I did not get a single question about it : (
- I got a bunch of vApp question, so take some time to study it, specially their configuration options.
- The majority of the question are multiple right choices, some times 2, some time 3 right answers, so be attention to those.


Whish you all good luck

End of Life (EOL) VMware Consolidated Backup

A few weeks ago VMware announced the EOL for VMware Consolidated Backup, formerly known as VCB.

For now on you should be thinking of implementing VMware Data Recovery, VBC still available but it will not be compatible with newer versions.

VDR is not the best backup solution yet, but VMware believes with the vStorage APIs made available, other companies will start creating theirs own backup solution. I can barely wait...

How check if your VMware License file is OK

I’m pretty sure there are plenty of VI3 out there, so I’ll post another topic related with the VMWARE Licensing for ESX 3.5… let’s get it on.

A few posts behind I talked about how to set up your license server to read multiple licenses file, but if you like to combine these multiples in just one ?!?!?

It would be amazing if there’s a way so you can test if your LIC file is OK and has all the features included into, right ?

We know that sometimes it’s expensive to create a lab environment for each aspect of systems, so what can you do about it ?

VMWARE has a simple webpage where you can test if your consolidate LIC file is the way it supposed to be.

Veeam FastSCP works

On my last post you saw that I found a tool that promises miracles when transferring VMDK files over DATASTOREs.

So, I did my own test to guarantee that there are performance improvements using Veeam FastSCP over regular SCP copies.

I took a single 20gb VMDK files with just 10gb of this file was in use, the rest was blank blocks.

As you can see on the chart comparison bellow, SCP took 27 minutes to copy the file when Veeam FastSCP took just 13 minutes.

Well… I would say it works and I can add that the bigger your file is and as much blank blocks you have the bigger you be the differences between then.

Do your own test and let me know the results… to me it worth’s a try!!!

See you

Transfering VMDK files

I’ve been working on a project for a client that is moving it’s datacenter to another one, in another city.
So, there is a need to move their guests to another VMWARE environment on the new datacenter. Both datacenters are connected with a fast LAN-to-LAN link, so it’s just a matter of doing the math …… size of VMDK x network speed.

Then I realized because of big VMDK files and several concurrent copies over the network would take me to a huge outage on the guests and probably the client would not approve it or be very upset.

Doing some search on the internet I found Veeam FastSCP, despite of the fact it’s free, it has some features that makes it very interesting:
- traffic compression
- empty block removal
- 6 times faster then SCP

Well, at least that’s what their website promises…
Let’s give it a shot…… I will let you know.
