Cisco MDS 9148 SAN switch model is the best product. It is highly reliable and at a low cost, easy to deploy, easy to upgrade, easy to configure and easy to administer. This gives effective performance when used for SAN switch connectivity between hosts and storage boxes. It supports reverse compatibility 4/8/16 Gbps of throughput. When configured in redundancy there is a 0% chance of a path missing between the host and storage array. It also supports short distance and long-distance ISL configuration without any issues. WebUI is simple and easy to understand.

The primary use case is as a standard SAN (single-site), and metro-SAN (10-15km between datacenters). Both types of switches, fixed and directors, are used.

We use this solution to manage our storage and inner network solution.
