Various embodiments are generally directed to an apparatus and method to receive client traffic comprising information at a primary cluster of a clustered system over a communications link, perform, a replication operation on the clustered system to replicate the information on a secondary cluster of the clustered system, and determine a client traffic throughput for the client traffic and a replication throughput for the replication operation. In some embodiments, the apparatus and method may include buffering one or more write operations to control the client traffic such that the client traffic throughput is less than or equal to the replication throughput for the replication operation.
