Introduction to High-Availability Clusters On Linux And Other Systems

Comes as an added product for Solaris operating systems.
Until Solaris 9 (inclusive) was scarcely used - everyone used Veritas cluster.
Has an active-passive mode and a phony active-active mode. In the 'active-active' mode, all I/O from the 2nd node flows via the LAN to the first node, so only one node actually accesses disks.
Has a nice GUI to configure it - which is somewhat complicated to use.
(Probably) works only with SCSI disk devices.
