vSphere 5 & 5.1 Licensing

As of today's announcement, the new vSphere licensing for 5 and 5.1 will be by per processor licensing moving forward from 27th August 2012.  This eliminate the need of vRAM entitlement which was used in vSphere 5.0 last year.

This come effect for all new and existing customers on vSphere 5.0 while vSphere 5.1 is yet to be released for download.  The updated End User License Agreements (EULA) will replaces and supersede statement can be found here.

This change was decided due to the feedback and confusion created when vRAM entitlement was release last year in partners and users.  Though vRAM would benefit people with bigger environment, the core processor licensing was still easier for everyone.

You can read from the vSphere 5 Licensing white paper here.  You may also refer to all the resources of vSphere whether for 5.0 or 5.1 all at this place.

I have the table of the license entitlement between 4.1 and prior and the new change for 5.x below:

Samsung Galaxy Note 10.1 Review

Image
Happen to be invited for a private Facebook fan event where 6 of us were invited.  It was a privilege so will just head to the review.  You can read about the technical specification here which I would go in details.  There is a review on the build which I never get to test it which you can view here.  So far I still like my ASUS Transformer TF101.  The build was solid and the price then was also good.

The brochure I receive on arrival.






The familiar Samsung brochure from all the Galaxy series.

The tablet on the table.  This is the white set that was presented to us on the day.  Just like the Galaxy Tab 10.1, it look just the same of the cause with just one different the S Pen which uses special touch technology from Wacom to be more precise than styluses for the iPad or iPhone.  This also add cost to the tablet which typically one Wacom writing pad would cost  you a price.

The display is a bit reflective and if you asked yes its using TFT instead of AMOLED display.  Yes a bit disappoi…

VCAP5 Upgrade Path

Image
For those who are already VCAP5-DCA, currently there is a a fast upgrade track.

Typically you would need to take up VCP5 followed by the various VCAP track e.g. VCAP5DCD or VCAP5DCA to be certified VCAP in the different tracks.

However for now till 9th Oct 2012, the VCAP5DCA requires you only to take up VCAP5DCA if you are already VCAP4DCA to be upgraded.  You will also get awarded wth VCP5.

So hurry!









As for those who are already VCAP4DCD, you just need to take up the VCP5 and VCAP5DCD to be VCAP5DCD.

VCAP5-DCA Passed!

Did the VCAP5-DCA beta exams which comprises more than a hundreds of questions.  As the kits are limited there were only a few participants or should I say unless you manage to book the exam for a time slot of your choice.

Its has been a long waiting time and finally receive a note that I have passed.  I didn't manage to finish the exam though but there are just too many things on each task to be completed.  I must congrats the certification team for able to rush the results out.  They have been providing us the update of the progress.  Having that there are the current certifications to be assessed and the betas.  It won't be easy.

I have drop some feedback to the certification team on some of the "not so specific" tasks which need to be completed.  That is the purpose of going through the beta exam.  Feedback is really important.

I managed to secure one slot before the closing date and brave through it.  4 hours of lab.  Experience wise?  Well its very slow co…
