Chapter 5. Adding New Storage via SAN with Reference to PCMCIA and USB

"Nothing has changed on my system" is a common statement made by people calling an IT helpline for assistance. It is a well-known fact that no system remains stagnant forever, so for those who try to achieve life eternal for their systems, ultimate failure awaits. Take racing as an apt analogy. If a racer never upgrades to a newer engine (CPU) or chassis (model), then the racer will have a hard time staying competitive. Thus, in this chapter, we discuss how to add more to our "racer."

The term storage area network (SAN) will become, if it is not already, a common one among system administrators. The capability to consolidate all storage in a data center into large frames containing many drives is indeed the direction companies will, and need to, take. Large enterprise operating systems such as HPUX, AIX, Solaris, SGI, MVS, and others have made very impressive leaps in that direction. Therefore, Linux must "Lead, follow, or get out of the way." With vendor support from Emulex, QLogic, and others, Fibre Channel storage has become commonplace for Linux, and now system administrators must learn the tricks of the trade to become power players.

In this chapter, we discuss adding disk storage (the most commonly added item) through SAN and touch on PCMCIA/USB. We begin by defining the configuration used to demonstrate our examples and by discussing some highlights. We then discuss the addition of a PCI device to connect additional storage. Next, we move to a discussion of adding storage to a defined PCI device. Due to its complex nature, we conclude this chapter by covering a few topics with respect to adding storage through PCMCIA/USB.
