Using SNAplus2 in a High Availability Environment

Using SNAplus2 with MC/ServiceGuard

	Using SNAplus2 with MC/ServiceGuard
	MC/ServiceGuard (product number B3935AA) is a specialized facility for
	protecting mission critical applications from hardware and software
	failures by allowing you to organize groups of servers into clusters and
	applications (like SNAplus2 ) into packages. (See Managing
	MC/ServiceGuard, HP Part No. B3936-90003). Using SNAplus2 in a
	ServiceGuard cluster protects against many of the unexpected failures
	that can interrupt SNA network access to end users. The strategy
	employed by ServiceGuard is to prevent a single failure from disrupting
	service by providing software and hardware redundancy. The typical
	SNAplus2 environment might look like the following example when used
	with ServiceGuard.
