A storage area network (SAN) is itself a network. How is this both an advantage and a disadvantage?

What will be an ideal response?

The advantage comes from the efficiencies that a SAN, as a separate network, can bring to storage access and retrieval. The disadvantage comes primarily from the initial cost and complexity of setting up the SAN infrastructure. As with any business solution, the decision of whether to use a SAN will be based on how cost-effective and efficient a SAN would be for the organization.
