Now it takes some work to properly implement it, but essentially what DRS provides us with is vMotion for load balancing purposes. So for example, let's say that we have the two ESXi hosts shown in the slide and in reality we would probably have more hosts than this, but essentially what DRS is going to do is this. If ESXi host one starts to become overwhelmed we can use vMotion to load balance. We can take this virtual machine and we can migrate it to a different host with no down time. All right, that's one of the main purposes of vMotion is to allow us to load balance across ESXi hosts, but identifying when these vMotions need to happen, you know, identifying there's an imbalance across multiple ESXi hosts becomes increasingly difficult as your environment gets larger and larger. That's where DRS comes in. DRS will automatically…
