we have a Cisco/IBM solution based on 3 IBM FastT600Turbo and a Cisco MDS 
9509, giving us around 56 TB of managed storage.

So far we are very happy. One of the greatest features is flash-copy. You 
get nearly instantaneous backups at the logical level. Since there is also 
redundancy at the physical level this seems to cover most eventualities. Of 
course only time will tell how well this works in the real world.

Cheers, Sebastian
