Virtual machines in a computer system cluster, or cloud environment, require access to their assigned storage resources connected to the virtual machines via storage area networks (SAN). Such virtual machines may be independent from associated physical servers in the computer system cluster on which they are deployed. These virtual machines may dynamically migrate among assigned physical servers while maintaining access to their connected storage resources both from the source physical server and the target physical server during the migration.

Flexible deployment and migration of virtual machines

Validating access consistency to a set of accessed resources over a set of virtual ports, including determining a number of virtual ports to provision, allocating each physical port and each virtual port among two or more buckets, and validating access to the set of accessed resources via each virtual port over each physical port that is allocated to the same bucket. At least one virtual port in the set of virtual ports shares no bucket with at least one physical port in the set of physical ports, and each virtual port is only validated over each physical port with which the virtual port shares a bucket.
