A Meshed fabric SAN topology is recommended when the customer requires a high-performance, port- efficient network with many-to-many connectivity and cannot predict I/O traffic patterns. This topology provides multiple paths between devices, ensuring high availability and redundancy. It is flexible and can easily accommodate changes in the network, such as the acquisition of another company, making it ideal for environments with dynamic requirements.
