OpenMosix::HA Description

OpenMosix::HA is a High Availability (HA) layer for an openMosix cluster. OpenMosix::HA is a High Availability (HA) layer for an openMosix cluster.SYNOPSIS use OpenMosix::HA; my $ha = new OpenMosix::HA; # start the monitor daemon $ha->monitor;This module provides the basic functionality needed to manage resource startup and restart across a cluster of openMosix machines.This gives you a high-availability cluster with low hardware overhead. In contrast to traditional HA clusters, we use the openMosix cluster membership facility, rather than hardware serial cables or extra ethernet ports, to provide heartbeat and to detect network partitions.All you need to do is build a relatively conventional openMosix cluster, install this module on each node, and configure it to start and manage your HA processes. You do not need the relatively high-end server machines which traditional HA requires. There is no need for chained SCSI buses (though you can use them) -- you can instead share disks among many nodes via any number of other current technologies, including SAN, NAS, GFS, or Firewire (IEEE-1394).Commercial support is available for OpenMosix::HA as well as for openMosix clusters and related products and services.
