There are quite a few options you can look into. CNT builds protocol converters that you can use to convert FCP <-> IP <-> FCP (fiber channel protocol) and accomplish data mirroring via a WAN connection. Other DWDM / Dark Fiber options exist too, and can play well with the larger disk subsystem's software based copy services such as PPRC (IBM) and SDRF (EMC). Collectively, these are all high cost solutions, but offer lots of flexibility and HA type configurations. Other, less expensive methods/tools probably exist too--
