Comparison of Libraries, Tape Drives and Disk Storage Systems

Hi!

I am new in Storage Technologies since I come from Networking. I have to face storage issues at my new job, so I have basic questions. Let´s focus on HP solutions: which main differences has selecting a library, a tape drive or a disk storage systems?

The second question is: is SAN always referred to a FC network? Why iSCSI doesn´t seem to be a real good solution nowadays for SAN environment? It seems that EVA, P2000 and other storage systems are thought for Fiber Channel, although we already have 10 Gigabit Ethernet. IS the reason maybe that FC is more resilient and reliable for SAN?

Thank you very much.

Thanks for your information, it´s quite clarifying. Is library and tape drive the same thing? Are libraries or tape drives then used to storage data that are no longer usually accessed to and for the every day work we have EVA4400 for example?

A library is a box with a tape drive in it plus magazines full of tapes, and a robot that takes tapes out of the slots and puts them in the drives.
