Multi-initiator Two hosts Two SCSI-2 adapters (one per host) One SCSI-2 bus Two SPs Multi-bus/ multi-initiator Two hosts Four SCSI-2 adapters (two per host) Two SCSI-2 buses Two SPs Adds backup host to two-SP configuration. Applications can continue after the failure of any disk module. If one host, one SCSI-2 adapter, or one SP fails, the other host can take over the failed host's disks if the array and hosts have been appropriately configured with LVM. If both hosts intend to access a particular disk simultaneously in this configuration, each host should access the shared disk using the same primary controller to avoid continuous automatic controller ownership transfer, which is not supported as a dynamic feature. Provides the highest availability and best array performance for dualhost configurations. Applications can continue after the failure of any disk module. If one host, one SCSI-2 adapter, or one SP fails, the other host can take over the failed host's disks automatically when primary and alternate paths have been configured using LVM. CAUTION 4-4
