1. A method comprising:
- filtering one or more available ports on a data storage system to determine candidate ports based on at least their hardware redundancy information, the data storage system comprising one or more data storage volumes; and
allocating one or more ports to the data storage volume from the candidate ports based on parameters to enable communications from a host, using the one or more allocated ports, to the data storage volume through the one or more storage components, the host having one or more initiators,wherein the parameters comprise at least two of a maximum paths parameter to determine a maximum number of ports to allocate, a paths per initiator parameter to determine a number of ports to allocate for each initiator, and a minimum paths parameter to determine a minimum number of ports to allocate.

Abstract
In one aspect, a method includes filtering one or more available ports on a data storage system to determine candidate ports based on at least their hardware redundancy information. The data storage system includes one or more data storage volumes. The method also includes allocating one or more ports to the data storage volume from the candidate ports based on parameters to enable communication from a host, using the one or more allocated ports, to the data storage volume through the one or more storage components. The parameters include at least one of a maximum paths parameter, a paths per initiator parameter and a minimum paths parameter.
