Resource Pool Setup Question
We are currently not using resource pools within our environment. What we are looking to do is implement resource pools with memory reservations based upon our VM sizes. For example, we'll create a 4GB...

The resource pool reservations have no affect on the VM's reservation in the pool - they are independent The problems you had with HA is one issue - another is by assigning reservations to all VM's you...

If we have an 8 host cluster, each using about 90% of its total 132GB of memory, and the VMs are configured in resource pools to reserve about half of their memory, that means we would need about ~60GB...

Essentially, yes. If you're using the percentage-based admission control policy (you should be), then simply use the following trivial formula, set, and forget. The good folks at VMware have done the...

Using you example of an 8 node cluster 1ith 132 GB total - for a 4 GB VM with a 2 GB reservation there will need to be 2 GB of free RAM on a single host for that VM to start in the cluster - so now let...

Gav0 - Thank you for your examples. When you say setting a 50% reservation at the VM level, you do mean going to each VM and setting this correct? If your objective is to save disk space by...

Thank you for that explanation Gav0. I do like your idea about a LUN dedicated to swap files. We could potentially run into problems with VMs starting if the datastore were to be lost though correct?...
View ArticleRe: Resource Pool Setup Question
If the lun datastore is not available then ESXi will default to storing the swap files with the VM files, so as long as their is space on the VM datastore they will power up. If the lun were to go...

Nice, thank you Gav0. So with expandable reservations enabled, any of the VMs within the resource pool will be guaranteed a reserved amount of physical memory. If the VM requests memory outside of what...
