The approaches I'm aware of: * Buy one for every node. Typically the most expensive approach, but simplest and most reliable. * Buy a USB switch with auto-switch capability. These let you connect a USB device (or devices) to multiple computers. You'd have to test whether the auto-switch works in your setup (they're typically marketed for printers). The switch becomes a single point of failure. * Use a USB-over-Ethernet device. These are generally proprietary and become a single point of failure. You'd have to test whether the latency is good enough for your purpose. (In this case, you could instead get a GSM modem with built-in TCP/IP connectivity, but it would still be a single point of failure.) * If the device is for non-essential capabilities, manually move it after a failover. _______________________________________________ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
