CONNECTIVITY ANALYSIS AND A MASS STORAGE SYSTEM CAPABLE OF CONNECTIVITY ANALYSIS

摘要

A method for connectivity analysis, the method may include: obtaining, by a mass storage system, hierarchical cluster mapping information that is indicative of host computers that belong to a cluster of host computers and of host ports of the host computers of the cluster; receiving, from at least one intermediate device of a network that couples the cluster to the mass storage system, host port state information indicative of a state of at least one host port that belongs to one or more host computers of the cluster; estimating, by the mass storage system, an estimated state of at least one entity out of (a) the one or more host computers, (b) the cluster and (c) at least one path out of a group of paths that couple the mass storage system to the cluster; wherein the estimating is responsive to the hierarchical cluster mapping information and at least one out of (a) the host port state information, and (b) traffic statistics related to traffic conveyed over the at least one path; determining whether to generate an alert, by the mass storage system, in response to the estimated state of the at least one entity; and if it is determined to generate an alert then generating an alert.
