In this video, Russ Long discusses how reservation pools can affect the validity of your DRS cluster. Learn how DRS handles pool reservations and how those reservation are calculated.
- [Instructor] Now, DRS is required…in order to create resource pools.…So when implementing resource pools we can adversely…impact the way our DRS cluster functions…or even the validity of the cluster itself.…So there are three statutes for the cluster…and it's pretty simple.…Valid is green, which is good.…Overcommitted is yellow, that's the bad.…Invalid is red, and that's the ugly.…So let's break this down.…Valid, everything is good, all the reservations are met,…we are happy.…
Overcommitted, this is yellow, and in this case…everything is still able to run but there are not enough…resources to meet the reservations of the VMs…within the parent pool and all its children…resource pool, or nested pools.…Now this often happens when cluster capacity…is reduced suddenly.…Now, the invalid, or, red, cluster.…In this case, we are breaking our own resource pool rules.…
We no longer follow our shares or reservations.…The danger, at this point, is if a VM becomes starved out…or unstable due to contested resources.…Now, remember, this is all within our resource pools.…
