Are your 2 SANs mirrored? If not, you may not be accomplishing the same thing that Heimatplan is. It sounds like he is running active/active, but I could be mistaken. None of Dell's SAN solutions provide an active/active setup (Equallogic nor Compellent), as far as I know. It sounds like you have 2 SANs that are separate, which will provide you with 50% of your storage staying online if one were to go down, assuming you're just operating completely independently. They could be replicating to each other, which would provide quicker recovery, though.

SAN availability is typically viewed as the number one priority when designing your storage architecture; more important than throughput or IOPS. Of course, different businesses have different needs. This is really something your business owners would need to determine more than IT: how long can our business operate without our systems? Active/active is great, but typically expensive. Your SAN vendor is a great resource when planning/architecting things like this.
