MySQL does not really care if you use SAN or directly attached hardware. In fact it does not even know.

We have number of customers using SAN with mixed results. Some are happy some went back to directly attached hardware, using large amount of MySQL boxes instead and MySQL replication or Partitioning (more likely for 2TB)

One thing you should keep in mind - SAN are good for ease of management, but they do you no magic in terms of performance. Well... They do in a sense as they may have very lage number of hard drives, but do not expect much better performance per drive, unless your application working set fits in SAN memory of course.

SAN are also likely to increase latency even though they have good throughtput, so for latency critical sequential writes, such as log files you may consider using directly attached
couple of drives with battery backed up cache - this is if log writes are being bottleneck for you.
