Today, the vast majority of vendors selling SAN solutions are planning to provide both Fibre Channel and IP-based products to accommodate their customers' requirements.The people who have direct responsibility for designing and implementing SANs desperately need more detailed information on product capabilities and interoperability, i.e., what version of a particular backup application works with a specific database or operating system level. Therefore fibre channel is being selected as an avionics communication solution for a variety of new military aircraft and upgrades to existing aircraft. Chapter 5 describes the product suite vendors have developed for Fibre Channel servers, storage, interconnects and other components. Under the ANSI X3T11 standards, regulation, up to 126 storage devices (nodes) can be linked.

Storage-area network storage is in a period of major change -- it's getting much easier. Testing at the fibre channel protocol level detects bad receivers, transmitters, media, and fibre channel processors, but fails to find problems in the inner workings of an LRU. The more customers and technologists align their common goals, the more quickly viable solutions can be put into the customers' hands. Given the lead time required for hard copy publishing, it is impossible to capture this very useful but granular information. A SAN provides storage, access to client devices, but does not impose any in-, herent restrictions on the operating system or file sys-, tem that may be used. We have the Servers, which are not directly accessed by the end-user.These Servers provide the computational power, processing and other resources to the end-user terminal which is typically a desktop computer.
