server pools in Halfin-Whitt regime. Class i customers has priority for service
in pool i for i = 1, . . . , d, and may access some other pool if the pool has
an idle server and all the servers in pool i are busy. We formulate an ergodic
control problem where the running cost is given by a non- negative convex
function with polynomial growth. We show that the limiting controlled diffusion
is modeled by an action space which depends on the state variable. We provide a
complete analysis for the limiting ergodic control problem and establish
asymptotic convergence of the value functions for the queueing model
