Abstract

An apparatus comprises at least one processing device configured to identify a plurality of networks providing connections to a data storage system, to determine network topology dependencies associated with resources shared by different ones of the networks, and to generate network sets including first and second network sets comprising first and second subsets of the network determined to have first and second sets of network topology dependencies for at least one type of resources. The at least one processing device is further configured to select a given set of networks for at least one client device accessing the data storage system, the given set of networks comprising at least a first network in the first network set and at least a second network in the second network set.

Dependent claims

An apparatus comprising:

at least one processing device comprising a processor coupled to a memory;
the at least one processing device being configured:
to identify a plurality of networks providing connections to a data storage system;
to determine network topology dependencies between the plurality of networks, the dependencies being associated with one or more types of resources shared by different ones of the plurality of networks;
to generate two or more network sets, a first one of the two or more network sets comprising a first subset of the plurality of networks determined to have a first set of network topology dependencies with one another for at least one of the one or more types of resources, a second one of the two or more network sets comprising a second subset of the plurality of networks determined to have a second set of network topology dependencies with one another for said at least one of the one or more types of resources;
and
to select a given set of networks for at least one client device accessing the data storage system, the given set of networks comprising at least a first network in the first network set and at least a second network in the second network set;
wherein the first subset of the plurality of networks are implemented using a first set of resources of said at least one of the one or more types of resources, and the first set of network topology dependencies indicates that the first set of resources implementing the first subset of the plurality of networks have at least a first threshold likelihood of failing together;
and
wherein the second subset of the plurality of networks are implemented using a second set of resources of said at least one of the one or more types of resources, and the second set of network topology dependencies indicates that the second set of resources implementing the second subset of the plurality of networks have at least a second threshold likelihood of failing together.

and
to select a given set of networks for at least one client device accessing the data storage system, the given set of networks comprising at least a first network in the first network set and at least a second network in the second network set;
wherein the first subset of the plurality of networks are implemented using a first set of resources of said at least one of the one or more types of resources, and the first set of network topology dependencies indicates that the first set of resources implementing the first subset of the plurality of networks have at least a first threshold likelihood of failing together;
and
wherein the second subset of the plurality of networks are implemented using a second set of resources of said at least one of the one or more types of resources, and the second set of network topology dependencies indicates that the second set of resources implementing the second subset of the plurality of networks have at least a second threshold likelihood of failing together.
