Abstract
Servicing an access request using a plurality of replicas of data includes determining which of the replicas are available and selecting one of the replicas for servicing the access request based on which of the replicas are available. At least one other replica is indicated as not available in response to receiving a monitoring message indicating that the at least one other replica is subject to degraded performance. The monitoring messages are independent of the access request. The monitoring messages may be SNMP messages. Servicing an access request using a plurality of replicas of data may also include determining if each of the SNMP messages affects the availability of the replicas. The replicas may be selected in round robin fashion or randomly.
