Wanted: Geographically distributed filesystem solution

I'm looking for a means to ensure that servers in the two or three datacenters, connected in a ring via IP through two ISPs, can distribute load and/or replicate data among at least two SAN-class disk devices.

I want to evaluate several solutions, and I'm open to solutions ranging from free, off-the-shelf, off-the-top-shelf (ie, really expensive), to custom designed by leading tech suppliers.

(Please help)

NAME
aoe-discover - tell aoe driver to discover AoE devices SYNOPSIS
aoe-discover DESCRIPTION
The aoe-discover command tells the aoe driver to discover ATA over Ethernet (AoE) devices on the network. All network interfaces will be probed with a AoE config query broadcast. If the aoe-interfaces command has limited the allowable network interfaces, only devices discovered via allowable interfaces will become available. The default is to make available all AoE devices found on all accessible ethernet networks. It's good to run the aoe-discover command after running aoe-interfaces. EXAMPLE
In this example, the root user on a host named nai loads the aoe module with only eth0 allowable for AoE traffic. After remembering that shelf 7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list of allowable network interfaces and then calls aoe-discover to ask the aoe driver to look for new AoE devices. nai:~# modprobe aoe aoe_iflist="eth0" nai:~# aoe-stat e10.9 eth0 up nai:~# aoe-interfaces eth0 eth3 nai:~# aoe-discover nai:~# aoe-stat e7.0 eth3 up e7.1 eth3 up e7.2 eth3 up e7.3 eth3 up e7.4 eth3 up e7.5 eth3 up e7.6 eth3 up e7.7 eth3 up e7.8 eth3 up e7.9 eth3 up e10.9 eth0 up SEE ALSO
