Chapter 1: Overview Connecting Devices to the SAS6160 Switch

LSISAS6160 SAS Switch User Guide

A separate cable with a Mini SAS connector on each end is used for each connection. All eight servers can access data on the RAID array. If more storage capacity is required in the future, the RAID array could be expanded, or a configuration with a second cascading switch could be created, as shown in the next example.

The third example (Figure 12) shows eight servers and one cascading switch connected to the SAS6160 switch. Several JBODs and RAID arrays connect to the other switch.

NOTE: Example 5 and example 6 also show configurations with cascading switches.

Figure 12: Example 3, Multiple Servers and a Cascading Switch

This example shows how you can cascade two SAS6160 switches to increase the number of devices in the SAS domain. Like in Example 1, all of the servers can access all the data storage devices, or you can implement a zoning configuration to restrict the access.
