We have also seen that it is wise to proceed carefully. Here are some things we have learned.
Storage is often the hardware that users spend the most time managing.
The most common reason for working with storage is adding additional capacity to a system. Since on a SAN, the storage is physically separate from the system, connecting additional storage is like adding a node to a network. In this case it is usually Fibre Channel, not Ethernet, but the independence is similar. Just as workstations are not affected by another being brought on-line, so new drives can be put on a FC SAN, without affecting operations. This storage can then be mounted on the CPU that needs it and immediately made usable.
