Abstract
Techniques and mechanisms for establishing quorums on an object-by-object basis; e.g., by associating quorum schemes, quorum-eligibility groups and/or quorum rules with objects on an object-by-object basis. For example, a certain quorum scheme may be associated with one object in a system and a different quorum scheme may be associated with another object in the system. A management system may be configured to be part of a quorum-eligibility group of an object based on any of a variety of factors, including any of: the number of management systems in the system, the quorum rule to be employed; whether an instance of the object is stored in a same fault domain of at least one of the management systems that are members of the quorum scheme; and the desire to maintain high availability of the object in response to various failure scenarios.
