We have storagehungry customers, and centralizing storage for multiple customers and at the same time safekeeping backup-data for multiple customers takes the storage demands to new levels. Who has a larger SAN, and only using 1 GB/s links today? I mean 10GBe, FiberChannel, Infiniband are all technologies that eliminates the bandwidth issue, it is just a matter of infrastructure, and even with 1 GB/s you can achieve much higher bandwith, bonding 2, 4 or 8 gigabit ports...
