To create a suitable configuration, run the SDM utility and create the zone groups
shown in the following figure.
Figure 9: Creating Zone Groups
Next, use the SDM utility to assign the following permissions, by creating zone sets:
„ Zone group 6 accesses zone groups 8 and 9, and vice versa.
„ Zone group 7 accesses zone groups 9 and 10, and vice versa.
1.6 Connecting Devices to
the SAS6160 Switch
The rules for connecting devices to the 16 SAS connectors on the SAS6160 switch are as
follows:
„ Any SAS initiator can be connected to any SAS connector on the switch.
„ Any SAS target can be connected to any SAS connector on the switch. A target can
be a RAID array, a JBOD, or another switch. Individual SAS drives or SATA drives may
not be connected to the switch.
„ Switches can be cascaded by connecting any SAS connector of the downstream
switch to any SAS connector on the upstream switch.
„ When SAS zoning is used, and multiple SAS6160 switches are used in the domain,
the switches can be cabled directly to one another.
„ Two switches can be connected with more than one cable to increase bandwidth
between switches.
„ All SAS connectors on the switch are Mini SAS, wide port style connectors. In
addition, connector 0 and connector 2 are keyed for active cables (see
Section 1.4,
SAS Connectors and Cabling ).
„ All connections must be x4. For any other configuration, contact your field
applications engineer.
„ Maximum connections allowed:
— Six cascaded expanders with each switch counting as one expander
