Ressources allocations

[brodyy]

Hi all,

I have a question about ressources allocation on ESXi hosts.

For example, I have 3 ESXi hosts with 12GB RAM each.

If I create a vCenter and add them into it, can I create a virtual machine with 24GB RAM (which she will really use) on one ESXi host ?

How a single ESXi host will gave the necessary memory that the VM want ?

We can't talk about DRS, right ?

Thank's.

Hi brodyy​

You can do this but the virtual machine will hang when the host memory limitation is full

vm status (memory consumed)

Hi asajm,

Thank's for responding.

So if i'm correct, we can't deploy a VM on a Host if she need more RAM than the host can provide (even if it's in a cluster)?

That's correct. A VM cannot be "spread" between multiple hosts simultaneously. It takes its resources from only one host at a time.

Thank's daphnissov for your answer !

Have a good day.

I said that you can assign memory for the VM more than the host memory

VM processing cannot exceed the maximum host memory
