  1. WAN VMotion – A Step Closer to a Private Cloud?
  2. VMotion Performance
]]> A couple of months ago i spoke about the possiblity of using VMotion over a WAN connection. Well yesterday at VMWorld, VMware announced that long distance VMotion was now supported for up to 200 Kilometers.

  1. WAN VMotion – A Step Closer to a Private Cloud?
  2. VMware vCenter 4 minimum RAM requirement, is it 2GB or 3GB?
]]> After reading through the ESX 4.0 and vCenter 4.0 Server Installation Guide I noticed the following requirement for adding vCenter to a Linked Mode group;

“All vCenter Server instances must have network time synchronization. The vCenter Server installer
validates that the machine clocks are not more than 5 minutes apart.”

Now this got me thinking…..

If a company had two Data Centers, lets say one in London and one in Amsterdam, They’ve decided they wanted to use vCenter Linked Mode to help them manage both Data Centers from a central location. According to VMware’s documentation this wouldn’t be possible due to the time difference between the two cities, London GMT and Amsterdam GMT+1 would mean that the vCenter Server clocks would be 1 hour apart.

  1. VCP vSphere 4 Practice Exam
  2. VCP4 vSphere 4 Beta Exam
  3. VMware vCenter 4 minimum RAM requirement, is it 2GB or 3GB?
]]> Tomorrow (17th July) I have the pleasure of sitting the VCP4 vSphere 4 Beta Exam, all 4 hours of it..

One of the main things I remember from taking the VCP3 exam was the amount of Configuration Maximum questions that VMware ftel the need to put into it. So I downloaded the vSphere 4 Configuration Maximum PDF and began reading, reading again and reading again. But nothing seemed to stick in my memory.

I have decided to make myself 3 mini vSphere 4 Configuration Max Practice Exams, so I can test myself over and over until I have learnt them. I haven’t added all the maximums to the exams, just the ones I think might be included in the VCP4 Exam.

]]> VMware has just released a joint Proof of Concept with Cisco titled VMotion between Data Centers.

Just lately I’ve been doing a lot of extra reading about how Cloud computing is shaping and evolving and I believe this to be another step taken by VMware to closer themselves on becoming a “Private Cloud” solution. Will we soon be seeing Virtual Infrastructures spanning separate Data Centers?

]]> I have just sumbled across “TWO” really easy to understand video thanks to Mike D Petrillo’s Blog and @HighTechDad on Twitter. I’m starting to hear more and more people talking about the Cloud and i’m finding that a lot people are not really exactly sure what “Cloud Computing” is.
