Oracle's GPL Linux Firewire Clustering

Posted by CmdrTaco on from the not-a-bad-idea dept.

Smoking writes "It seems that Oracle just released libraries to allow low cost Linux clustering solutions using firewire... Aside from the coolness factor (imagine a beowulf cluster of DV cameras...) it's quite new for Oracle to release GPL software. They also seem to include really useful tools for NIC failover, Wizard building framework and integration of the cluster into Gnome (via a gnomevfs plugin)."

      I have to confess that I don't actually know what HACMP requires at the switch level-- I've never used that particular HA implementation-- but setting up FC failover on SGI systems is about as simple as it gets. You just set a config file on the host telling it what the primary and failover device paths are for each LUN, and off you go. It requires no special configuration at all on the switch, so it's very close to plug-and-play.

This would fit into that level of sharing (and a few others as well), just better performance.

    Firewire doesn't need a computer to work. USB 2.0 and 1.1 need a computer for it to work, but you can actually plug a DV camcorder straight into a digital VCR.

    There is up to 50MB/s transfer rates (400Mbits/s) and the design is scalable, meaning the next iteration of Firewire will be 800Mbits/s, or possibly even 1.2Gbits/s

    Ease of use: FireWire cables are a snap to
    connectyou dont need device IDs, jumpers, DIP switches, screws, latches or
    terminators.

    It is an industry standard. Bar none. Purchase a new digital 8 or mini DV camcorder. What do you get? A firewire port right on the side.
