I think we are getting into a hypothetical land. Most Ignite users are having the reverse problem - index pages get evicted in the same way as data pages. Currently, we are solving it in a most awkward way by trying to give index pages a different eviction policy. A right solution would be to stick them into a different region and control the eviction policy for the index region separately from the data region. D.
