Is ALUA supported in PowerPath for all vendors?
Hi,
I'm with the VPLEX team and I need to understand an issue with PowerPath's ALUA feature - is it supported in a generic form for any array that reports itself to use ALUA paths, or is it vendor specific?
Thanks

Yarivz - did you have a specific 3rd party array in mind?

PowerPath works with three types of storage systems:
Active-active, Active-passive and ALUA (asymmetric logical unit access).
Your platform release notes provide information on the supported storage systems for your PowerPath environment.

Bob - I am researching implementing ALUA in VPLEX, and want to verify it will be supported by PowerPath. We currently identify as Invista if that matters...
Pragadees - Just to verify, PowerPath supports ALUA arrays no matter the vendor? If an unknown array type is connected to PP and claims to support ALUA, will PP accept it and work with the Active/Optimized paths the array presents?

Hello,
Just to provide clarification to your question, PowerPath only supports specific third party arrays. The PowerPath documentation for your host platform will have the specifics. If an array is directly connected to the PowerPath host that is not qualified it will not claim the luns.
When PowerPath identifies a lun as VPLEX you will have a choice of both basic failover and adaptive load balance policies.
