I installed a host on a Dell T420 and added a couple VM's to it and now having a bit of a storage issue. Read/writes seem to be very slow and after talking to Dell they tell me that I needed to use their ESXi Build since it has their controller drivers build in. The issue is that this Host and the few VM's are in production and I would prefer finding an answer without having to blow away the entire host and VM's. ESXi is installed on mirrored SD cards and the Storage that we are using is internal to the 420 setup in a RAID 5 config. My thought were, since it's installed on the SD cards that I could get another T420 (which I have) that has the same controller, install VMWARE on that system then put them in the production box, rescan the adapters for storage and then import my VM's. That's my short version of what I'm thinking. A couple questions I have are...is that possible or is there a way to update the drivers in the original system without issues? Any comments or suggestions are welcome. Thanks!
