The Storage Path chart displays historical statistics for paths used by the storage adapter on the selected ESX(i) host.
You can switch between adapters using the Adapter list below the performance chart.
The name of each storage device connected to the storage adapter via the selected path is specified after the ESX(i) host address (separated by a forward slash). It has the following format: <HBA>:<SCSI target>:<SCSI LUN>:<disk partition>
The following table provides information on predefined views and counters.
