Learning a lot about SANs and will possibly need to build one ... and am interested in the feasibility of distributing a SAN across a wide geographical area. Because of their wide private network and reasonable costs, Level3 comes to mind ... So the question is, if you need to build a fiber SAN across several datacenters, do you have the ability to have a real fiber connection between all of them, or is it a virtual connection, where your fiber goes to their routers, which goes to fiber between their routers, etc., making several hops between each node of your SAN ? This seems "bad" to me, because a router problem between the two nodes would essentially "break" the SAN - much like breaking a hardware RAID array by disconnecting a drive. Comments ? How are people, from the point of view of the network, building fiber SANs, and what providers (L3 ?) are they using ? thanks. __________________________________ Do you Yahoo!? Yahoo!
