Exactly. Given the allocation scores are as the following at this time:
native_color: main_rsc1 allocation score on srv-a1: -INFINITY native_color: main_rsc1 allocation score on srv-b1: 100 native_color: main_rsc1 allocation score on srv-b2: 100 native_color: main_rsc2 allocation score on srv-a1: -INFINITY native_color: main_rsc2 allocation score on srv-b1: INFINITY native_color: main_rsc2 allocation score on srv-b2: 100 native_color: main_rsc3 allocation score on srv-a1: -INFINITY native_color: main_rsc3 allocation score on srv-b1: INFINITY native_color: main_rsc3 allocation score on srv-b2: 100 And the resources would get assigned from top to bottom. Actually I've been optimizing the placement-strategy lately. It will sort the resource processing order according to the priorities and scores of resources. That should result in ideal placement. Stay tuned.
