I know about the the desc of fixed and MRU...But need to know at what situation we go for Fixed or MRU

[geddam]

Can you be more precise on "what situation we go for Fixed or MRU".....

Fixed is for Active-Active SAN

MRU is for Active-Passive SAN

MRU is prefered for active-passive storage.

Note the it mean active-passive on the same LUN... like for example AX, MD3000i, ...

Round robin is a way to do load balancing with active-active storage or (better) on storage with multiple active "channels" on the same controller, like for example Equallogic PS.
