My response to a Hyper-V vs. VMware vSphere 5 blog

I came across a blog on twitter today at the below URL. I thought I would at least spend a few minutes checking it out, due to some of the erroneous information in it I decided I would re-post but with my comments on some of the points raised.

Before people jump in, yes I work with MS technology but I’ve also spent years working with VMware hypervisors. Personally I don’t really care which one people use, it’s more important to spend time on CSI than argue over hypervisors. I do care about advice being correct though…. So here goes.

Hyper-V 2012 versus VMWare vSphere 5


Tasked with investigating whether a big P2V project should go the Hyper-V 3 (Server 2012) route or the VMWare (vSphere 5.1) route, I spent a few weeks testing both solutions. I also spent some time googling the subject – and that is actually why I am writing about it here. The classic “VMWare versus Hyper-V” search yielded absolutely no useful information. In this post I will add my findings in the hope that this will be useful to someone.

Testing the throttling capabilities of VMware converter standalone (continued)

Throttle me this throttle me that…

In-between exam prep I remembered I had started to test the impact of the P2V synchronisation feature. Luckily my lab was in exactly the same state as before I went on holiday therefore to finalise this was going to take me (hopefully) hardly any time.

I logged into converter and selected the last throttled job… previously I had set medium CPU throttling and 15MBps network transfer throttle.

P2V Disk Throughput limitation

I was doing some testing with the initial sync feature of VMware convert standalone and came across the scenario whereby transfer speed was rather low <10MiBs – for a 1GB network that seemed a bit low so I thought I would throw up some stats to see what was going on.

As you can see on the left the vmware converter agent is only achieving 7,777,182 B/sec. I’ll test this with a faster disk later.

Once the initial sync has completed I an another sync.

As we can see here the operation is far less IO intense on the disk (there have been very few changes to the disk since I took the initial sync.

I’ll run this again using another system with a better specirfication disk.

More with vmware vcloud service

Ok so I’m testing out vcloud service.

I’ve gone to the administration tab and have click add new users.

I’ve filled in the details as below

And we have a winner! This function seems to work J

I’m going to log out (currently logged in with the ADMIN account

So I logged in fine! (note you need to ensure you add “@” & [ORGNAME] on the end e.g. [email protected]

Then I tried to create another VM again…
