The iscsi protocol is a method for transporting standard SCSI blocks across IP networks. Traditionally, this is done over Ethernet to take advantage of the massive installed base and knowledge base. iscsi also allows you to build storage area networks over IP using something you already know and use everyday: Ethernet. In this way, iscsi removes the limitations of direct attached storage, including the inability to share storage resources across servers and to expand capacity without shutting down applications. What are the advantages of iscsi? An iscsi SAN solution costs less than 1/3rd the cost of Fibre Channel and uses standard Ethernet and TCP/IP, so all the same management and knowledge is leveraged. Easy setup, simpler management and lowered costs. What do I need to use iscsi connected storage? You need an iscsi based RAID external storage subsystem like the Promise, a standard Cat5E or Cat6 Ethernet cable, either a standard Gigabit Ethernet NIC with a free iscsi software initiator or a hardware iscsi /TOE HBA. If you want to connect more than two servers or build a SAN then you can use any standard Ethernet switch and connect it to that.
