> h3. Motivation
> As a prerequisite it's worth to mention that placement drive should be
> reliable and have sort of inner fail over that
> Despite the fact that it's valid to have more than one PD active actor (the
> one that will check topology, send leaseGrant msg, etc) it's better to have
> one only in order to reduce the amount of unnessesy calculations, messaging
> duplications and so on. It's worth to metnion that
