Installation guide

4.1 Configuration Overview
All DSSI shipping variations are cabled for single hosts. See Appendix B for
recabling to a dual-host configuration.
4.1.1 Single-Host Configurations
In a single-host configuration, one tape integrated storage element (ISE) and
up to six disk ISEs can be connected to one DSSI bus. Table A–4 lists the
building blocks for each single-host configuration.
For further information on single-host configurations, refer to the KFMSA
Module Installation and User Manual (EK–KFMSA–IM).
4.1.2 Dual-Host Configurations
In a dual-host configuration, one tape ISE and, up to, four disk ISEs can
be connected to one DSSI bus. Table A–4 lists the building blocks for each
dual-host configuration.
For further information on dual-host configurations, refer to the KFMSA
Module Installation and User Manual (EK–KFMSA–IM).
4.2 Single-Host Installation of an SF3xx Storage Array
This section provides the procedures for installing the SF3xx storage array in
a single-host configuration correctly and safely. Digital Multivendor Customer
Services or trained installing personnel must perform the procedures.
Make sure that all precautions for site preparation have been completed. Refer
to Chapters 1 and 3.
The procedures provide the steps to do the following:
• Inspect the SF3xx storage array for the correct configuration (Section 4.2.1)
• Cable the SF3xx storage array to the host system in the single-host
configuration (Section 4.2.2)
• Power up the SF3xx storage array after a successful installation
(Section 4.2.4)
• Verify the SF3xx storage array for correct operation (Section 4.2.5)
