'''PSA - Pluggable Storage Architecture''' | |||
* Manages storage multipathing | |||
* Allows simultaneous operation of multiple multipathing plugins (MPPs) | |||
* Native Multipathing Plugin (NMP) provided by default, can have sub-plugins (can be either VMware or 3rd party) | |||
** Storage Array Type Plugin (SATP) - unique to a particular array (effectively an array driver, like a standard PC hardware driver) | |||
** Path Selection Plugin (PSP) | |||
* Multipathing Plugin (MPP) - 3rd party, can run alongside or in addition to Native Multipathing Plugin | |||
'''PSA operations''' | |||
* Loads and unloads multipathing plugins | |||
* Hides VM specifics from a particular plugin | |||
* Routes I/O requests for a specific logical device to the MPP managing that device | |||
* Handles I/O queuing to the logical devices | |||
* Implements logical devices bandwidth between VM's | |||
* Handles I/O queueing to the physical storage HBA's | |||
* Handles physical path discovery and removal | |||
* Provides logical device and physical path I/O stats | |||
'''MPP / NMP operations''' | |||
* Manage physical path (un)claiming | |||
* Manage creation, and (de)registration of logical devices | |||
* Associate physical paths with logic volumes | |||
* Process I/O requests to logical devices | |||
** Select an optimal physical path for the request | |||
** Depending on storage device, perform specific actions necessary to handle path failures and I/O cmd retries | |||
* Support management tasks, EG abort or reset of logical devices | |||
'''PSA Claim Rules''' | |||
Used to define paths should be used by a particular plugin module | |||
'''LUN Masking''' | |||
Used to prevent an ESX from seeing LUN's or using individual paths to a LUN | |||
Add and load a claim rule to apply | |||
