Abstract
Technology is disclosed for stack isolation in a storage system including a storage network switch and multiple storage sub-systems (e.g., storage stacks). The storage network switch includes multiple ports and at least one of the ports is configured to dynamically connect to a device that can be either a storage controller device or a storage sub-system. The technology can receive an identification message indicating that a device is connected to a port of a storage network switch, determine based on the identification message at the storage network switch whether the device is a storage controller device or a storage sub-system, and transfer messages between the ports of the storage network switch such that the storage network switch prevents communications between storage sub-systems connected to the storage network switch, but allows communications between the storage sub-systems and storage controller devices connected to the storage network switch.
