Hi Shaheed, Currently N-way clustering is still not possible with CC, AS & SM. We completed the initial phase of this feature however it was not completed. You could refer mail thread "[Discuss] Clustering Feature Implementation for 4.1.0-Alpha Release" for details.
However at present [1] is valid. We could use Linux HA and deploy CC, AS and SM in Active-Passive mode.
