VAXcluster Systems Quorum

This issue of VAXcluster Systems Quorum (August 1992) covers critical performance and management topics for VAXcluster environments, including:

• HSC Cache: Detailed guidance on how the HSC cache improves I/O performance in VAXcluster systems, including configuration tips, tools (CNAT, VTDPY, DSCACHE), and management command strategies.
• State Change Timing: An analysis of VAXcluster transition and recovery mechanisms, explaining the phases involved in failure detection, reconfiguration, and database recovery, along with methods to manage transition timing via SYSGEN parameters.
• Large VAXcluster Configurations: Strategies for scaling VAXcluster systems, covering hardware requirements, system disk throughput, managing boot times, and system parameters (SCSCONNCNT, SCSRESPCNT, SCSBUFFCNT).
• Revision Management Level P1: A reference guide summarizing the revision levels for various VAX, VAXcluster, and storage components as of the journal's publication date.
