  Yes.  Just create an SQL cluster, and point the servers at the cluster.

  It will be slower, and database replication may not happen quickly.

  The servers will have to communicate with each other before handing
out IP addresses.

  Or, split up the IP pool ranges so that each server has their "own"
range that they prefer.  i.e. server 1 allocates from pool 1, and then
pool 2 if pool 1 is full.  Server 2 allocates from pool 2, and then pool
1 if pool 2 is full.

  There are other, more complicated ways of doing the same thing.
