The building strategy of iSCSI appliance
Dong Zeng, Jingli Zhou, Dong Xiang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2005
Even though the foundation of iSCSI (Internet SCSI) protocol is quite different from that of Fibre Channel, and maybe the original idea of replacing FC-SAN with truly IP-based iSCSI-SAN is hard to be fulfilled in short term, nobody can ignore the broadly existence and the bright future of the iSCSI technology. We present an introduction to build several iSCSI appliances in this paper from a single stand-alone iSCSI Target, an iManager-based iSCSI appliance, and our embedded iSCSI Target implementation to a RAIN (Redundant Array of Independent Nodes) -based iSCSI appliance. Not only do we offer some experiment results of our standalone iSCSI Target and our embedded iSCSI Target, our in-band and out-of-band iManager-based iSCSI Target designing strategy and performance comparison, but also give an explanation of our RAIN-based iSCSI Target implementation concerning to the topology of our RAIN Target, the node data distribution method and our ways to deal with the capacity-expansion-on-demand problem.
