VMotion on a HP C3000

Where I am currently we have just upgraded to a HP c3000 Blade server setup (about 6 months ago).

We are using VMware ESX etc but have run into a little problem.

Can you Vmotion across 2 different generation of blades e.g. Gen 1 blade to a Gen 6 ?

The Gen 1 blade uses a L5335 Xeon and the Gen 6 blade uses a L5520 everything else is as identical as can be (Ram, HDD etc)
 
It is not necessarily the Generation of the Server that makes a difference...it's the CPU. They don't necessarily need to be the exact same series, but need to fall into the same group. Per this article, I believe the 5300 and 5500 are not compatible. Call VMware to confirm.
 
In most cases vmotion requires the same architecture to work. This means same cpu (or same family and even that is limited.) VMware exports the CPU's capabilities to VM. You cannot move from a machine that has say: 3MB of cache and SSE2 to a cpu with 2MB of cache and SSE3 because virtual machine may be using features of the cpu and will in turn crash on move.

The is a way in the advanced options to disable the filter checks but when I played with that in the test environment it was very quick way to bomb a machine on move.
 
Yeah, I would check out EVC, but I wouldn't use it with 3.5, I don't think the support was really all there for it.
 
While we're on the subject (and not to derail the thread too much)...how many of you have moved on to vSphere 4? How has your experience been?

So far so good, it is definitely a much more matured product compared to 3.5.
Better performance, more flexible management, and the new fault tolerant feature; what more can you ask for 🙂
In my opinion there is nothing to loose other than initial cost, for upgrading to vSphere.
oh yeah, I dont work for VMware 🙂
