VMWare 3.5 u4 - VC 2.5 U4 Cluster question

[elgordojimenez]

Hello Guys,

I have just had a pretty cool discussion with one of my colleagues at work regarding 3leafsystems technologies :: http://www.3leafsystems.com/dvmm.html and resource distribution. Whilst talking to him I kinda realized that a VMWareCluster has a pool of resources but does not actually take resources from any host, only from the one the VM is configured on. So I want to know if this is true?. I checked the VMWare DRS and HA documentation and it says that the resources are part of the cluster and they work as 1, but the resources assigned to a vm belong to the host it is actually set to, so can a VM have resources from different hosts in the cluster and one given time?, for example can it have memory assigned from 2 different hosts at the same time?. That was one of the points i was discussing with my colleague, this 3leafsystems can act as a "cloud" of hardware and take it from any server in the "cluster".

also can this be accomplished with VSPhere maybe?

Thanks.

vSphere and VI-3 work in much the same way in that a VM can only utilize the resources from a single ESX host at a time - the 3leaf system sounds very similar to the clustering that done in the days of DEC VAX VMS clustering and other products in the Grid computing space - the two things to keep in mind with solution like this is you are fixed at using Linux and how perfectly matched does the underlying hardware have to be
