Installation guide

Figure 3–10 shows a dual-host configuration with one KFMSA in each
system. For DSSI VAXclusters, each system can have up to six KFMSA
adapters. Host systems can be VAX 6000s or VAX 4000 Model 300 systems.
The ISEs can be in either of the host systems or in SF2xx storage array
cabinets. This manual covers installation of single- and dual-host systems
only.
Dual- and tri-host systems must have:
• Two or more VAX 6000 or VAX 4000 systems
• Software licenses of
First System Additional Systems

VAXcluster VAXcluster
DECnet full-function DECnet end-node

On any cluster, the maximum difference in VMS revision levels between any two sys-
tems cannot be greater than one.
• DSSI adapters (KFMSA adapters for VAX 6000 systems)
• Ethernet hardware
• No more than six ISEs on each DSSI bus
