Explanation
Left—Left DSSI connector on SFx storage enclosure)
Right—Right DSSI connector on SFx Storage enclosure)
TOP—TOP DSSI connector on TFx Storage enclosure)
Bottom—Bottom DSSI connector on TFx Storage enclosure)
P0x—DSSI port x of the I/O panel
SF2–L—Left DSSI connector of the SF2 Storage enclosure)
TERM—Terminator
For combinations of Tape Loader with Disk Storage enclosure like TF1 & SF1
or TF2 & SF2 or TF3 & SF3 connect the bottom connector tape loader with
the right DSSI connector of the SF storage element. For example connect the
bottom connector of the TF1 with the right connector of SF1.
A.1.3 Stripeset Configurations
This section contains cabling diagrams for DECarray stripeset configurations.
• The SF7x storage enclosure must operate in split-bus mode
• DSSI bus termination is supplied by the transition termination module
(TTM) inside the SF7x storage enclosure
• Stripes are supported only in a single-system configuration
• DSSI termination of the Tape Loader magazine by terminators in bottom
DSSI connector.
