Installing a new processor on an ESXI machine

We have two esxi 4.1 machines that we're trying to get the same hardware on so we can eventually run vmotion.

To do this, the one host needs to have a second processor installed (and the first processor swapped out)... so going from one processor X5560 to two Xeon X5660 processors.

It's a Dell R710.

Just wondering if there's anything special I need to do?  Would it be as easy as powering down ESXi, swapping the processors, and powering it back up again?

What issues would I run into, if any?

At the same time I would also be installing more memory - the same # and type of modules of memory that are running in the first ESXi host.

There's not really any need to get the same processors, VMware vSphere have a function called EVC

Enhanced VMotion Compatibility (EVC) processor support

But as for your question, there is nothong for you to do on the ESXi host, it will auto-configure.

VMware KB: EVC and CPU Compatibility FAQ

VMware VMotion and CPU Compatibility

It was designed, so you could mix and match old and new servers, with new processors in a Cluster for vMotion and DRS.

OK i should never have mentioned vmotion... i need to get the same specs on both machines though, just because one is drastically underpowered (1 processor 4 cores, 12GB ram, vs 2 processor 12 cores and 96GB ram)

So I just pop the new processors in, and bump the RAM, and everything is gravy?

Ensure the memory is balanced between processors as per Dell documents.

Okay, just drop in the processors, usual anti static precautions.

nothing todo with ESXi configuration, it will self configure.

This did it.  ESXi automatically reconfigured, detected the processor, and all was gravy
