I have a Dell PowerEdge R520 that is currently running 4 virtual machines. It has an application, DC, Exchange, and file server vms. It has failed disks and a bad setup to begin with so I just want to back it up, put in new drives, configure a new array, and clone the vms back onto the new setup. Does anybody have the appropriate link to download Dell's custom ESXi iso for Dell? It is currently ESXi 5.1 with the VMware vSphere 5 Essentials, licensed for 2 physical CPUs. How would I apply that license when I reinstall? Also, while I'm at it, I want to add more storage. It looks like this server has a PERC H710 Mini array controller on it. Are there any Dell disk enclosures you've had success with or recommend? Right now I'd just had a couple TB but would expand at a later date.
