Mapping of logical volumes to host clusters

A distributed network for storing data, comprising:

• a data storage system comprising a plurality of logical volumes including a first subset of the logical volumes;
• a plurality of host computers in communication with the data storage system, the plurality of host computers including a first subset of host computers including at least a first host computer and a second subset of host computers including the first host computer and a second host computer that is not included in the first subset of host computers such that the first host computer is included in both the first subset of host computers and the second subset of host computers;
• and
• a processor in communication with the data storage system and the plurality of host computers, the processor configured for:
• in response to receiving a single first mapping instruction, mapping, by a processor, each host computer in the one of the first subset of host computers and the second subset of host computers to each logical volume in the first subset of the logical volumes;
• and
• receiving a single management command for performing a configuration operation on one of the first subset of the host computers and on the second subset of the host computers;
• wherein, when performing the configuration operation, the processor is configured for assigning a specified level of service to each host computer in one of the first subset of the host computers and the second subset of the host computers.

A computer program product comprising a computer-useable memory including computer-readable program code embodied therein for storing data in a distributed network comprising a plurality of host computers in communication with a data storage system comprising a plurality of logical volumes including a first subset of the logical volumes, the plurality of host computers including a first subset of host computers including at least a first host computer and a second subset of host computers including the first host computer and a second host computer that is not included in the first subset of host computers such that the first host computer is included in both the first subset of host computers and the second subset of host computers, the computer program product comprising:

• computer code for mapping, by a processor in response to receiving a single first mapping instruction, each host computer in the one of the first subset of host computers and the second subset of host computers to each logical volume in the first subset of the logical volumes;
• and
• computer code for receiving, by the processor, a single management command for performing a configuration operation on one of the first subset of the host computers and on the second subset of the host computers;
• wherein the configuration operation comprises computer code for assigning a specified level of service to each host computer in one of the first subset of the host computers and the second subset of the host computers.
