SAS Zoning Cabling
The SAS zoning configuration can only apply to the first layer of XCubeDAS system when
cascading multiple XCubeDAS systems. Usage examples are illustrated in the following.
Two Servers to One XCubeDAS / Two SAS Zones
In this case, XCubeDAS is configured to two SAS zones for access right control. There is no
storage expansion follows XCubeDAS system.
SAS zoning plan is listed as below:
Zone 1: Port 1 and Port 2. Port 1 is for host connectivity, Port 2 is disconnected.
Zone 2: Port 3 and Port 4. Port 3 is for host connectivity, Port 4 is disconnected.

Two Servers to One XCubeDAS / Two Zones
Two Servers to Three XCubeDAS / Two SAS Zones
In this case, XCubeDAS is configured to two SAS zones for access right control. There are
two XCubeDAS systems deployment for storage expansion follows one XCubeDAS system.
Only the XCubeDAS system on top layer can set SAS zones, the XCubeDAS systems
cascaded to it is only for storage expansion.
SAS zoning plan is listed as below:
Zone 1: Port 1 and Port 2. Port 1 is for host connectivity, Port 2 is for expansion.
Zone 2: Port 3 and Port 4. Port 3 is for host connectivity, Port 4 is for expansion.
