The fourth zoning allocation option, shown in the Quick Setup dialog, scans the blade chassis system for CPU blade servers with a storage blade in an adjacent slot. If the CPU blade server does not have a storage blade server in an adjacent chassis slot, the Sun Blade Zone Manager will not allocate storage to that CPU blade server.
Option 4 is best suited for chassis systems that contain: (1) an equal number of storage blade servers and CPU blade servers, and (2) each CPU blade server is installed in a chassis slot that is adjacent to a storage blade server.
For further instructions on how to create SAS zoning allocations for the whole chassis, see Allocating Storage to Entire Chassis: Quick Setup (Web).
