I do have two hosts, actually 9 to be specific. However, I'm looking at this from more of a hypothetical/design question. I'm trying to build out the initial stages of a vCloud and the best practice is to have a management cluster and resource group clusters. I also have to maintain a "legacy" cluster with our VM's that haven't been migrated to the vCloud. Since these are all currently in production, I don't have much wiggle room to dedicate a bunch of resources to building this out so to start, my management cluster was going to be a single host. And to keep the I/O off of the shared storage I really wanted to just use local disks. For some reason the SQL server for this vCenter is absolutely killing disk I/O (100MBps [yes big B] according to VeeamONE and vSphere client performance tab). Big picture I need to figure out what is happening there because that definitely seems ridiculously high, but it definitely brought up the original question of how to deal with updating a host where vCenter runs from local storage on that host.
