In this acronym, "Logical Unit Access‟ part is well understood but "Asymmetrical" at
the beginning could sometime confuse or make it sound little complicated.
So, What exactly is "asymmetrical‟ ? Well, if you google for the word "asymmetrical‟
you can learn many definitions around this word, but all trying to convey the same
message. In a nutshell it means – “when the two halves are not equal”, from storage
"multipathing‟ perspective it means – “Not all paths available to a LUN, necessarily
have same equal access”.
In this document we shall try and cover all aspects around ALUA & multipathing.
