4–4 Installing an SF200 Storage Array with a VAX 6000 Series System
4.2 Dual-Host Overview
As many as two VAX 6000 series systems can be used with a single SF200
storage array.
A single SF200 storage array requires up to three KFMSA modules
(installed in the system’s XMI backplane) to support the DSSI ISEs
resident in the SF200 storage array.
In a dual-host configuration, both systems must have up to three KFMSA
modules installed in the system’s XMI backplane to support dual-host
configuration guidelines.
In a dual-host configuration, one tape ISE and, or up to, four disk ISEs
can be connected to one DSSI bus. For further information on dual-host
configurations, refer to the KFMSA Module Installation and User Manual
(EK–KFMSA–IM).
Refer to Table 4–2 to confirm that the correct system configuration exists
to support the installation of the array.
