> Need to revisit keys/requests mapping procedure and map the update directly to stripe
on remote node.
> Here are some points:
> # Abovementioned will require adding stripes count attribute to node's attribute list
> # Need to make sure we take all benefits of biased locking and stripes never get mutually
blocked
> # locking all entries before processing request can be removed since it does not make
too much sense to atomic cache
