After the upgrade to ESX 4.0, the service console's partitions are stored in a .vmdk file. These partitions include /, swap, and all the optional partitions. The name of this file is esxconsole-<system-uuid>/esxconsole.vmdk. All .vmdk files, including the esxconsole.vmdk, are stored in VMFS volumes.
