DECarray Cabling Information
A.3 Stripeset Configurations with SF7x Enclosures
A.3 Stripeset Configurations with SF7x Enclosures
Table A–3 contains cabling information for DECarray stripeset configurations
using SF7x enclosures.
Note the following:
• The SF7x storage enclosures must be operating in split-bus mode.
• DSSI bus termination is supplied by the TTM module inside the SF7x
storage enclosures.
• If a DSSI bus is not connected to a SF7x storage enclosure, then DSSI bus
termination is accomplished by using a DSSI terminator (PN 12–31281–
01).
• Stripesets are supported only in a single-system configuration.
