Two new backend capabilities were added to Manila in order to help
administrators to control and balance their cloud resources. The capability
called `max_shares_per_share_server` allows the administrators to define a
maximum amount of shares that a share server can have. The capability called
`max_share_server_size` allows the administrator to set a maximum number of
gigabytes a share server can grow to, considering its instances, replicas and
snapshots. Both capabilities accept only integer values. If at least one of
these limits is reached, Manila won't consider reusing the referred share
server. If there aren't share servers available to reuse, Manila will create
another one to place incoming request. If none of these limits were specified
in the backend stanza, Manila will consider them as unlimited and allow share
servers to be reused regardless the amount of shares or the size they have.
