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)
