Using iSCSI Multipathing in the Solaris 10 Operating System 
by Aaron Dailey and Scott Tracy
December, 2005
This article describes how to use Internet Small Computer Systems Interface (iSCSI) multipathing in the Solaris 10 Operating System. Implementing iSCSI in a storage solution provides two important benefits: it can increase storage availability via fail-over protection and also increase scalability and throughput via link aggregation.
This article describes different approaches to implementing multipathing between an iSCSI initiator and an iSCSI target device. It reviews the reasons for multipathing, describes the different approaches that Solaris supports, discusses the trade-offs between those approaches, and provides recommendations for specific configurations.
This article contains discussions about: the iSCSI Protocol, iSCSI Support in Solaris 10 Update 1 and Solaris 10 Multipathing Options for iSCSI Devices.
