WebIt is then sent to the Network Layer 3 where it is placed into an IP datagram to form the TCP/IP packet. The TCP/IP packet is then placed into an Ethernet frame at the Datalink Layer 2; The “iSCSI Ethernet” frame is then sent out onto the physical network Layer 1 to be sent to the storage target. This process is shown in the following figure: WebThe iSCSI is a transport layer protocol running over TCP/IP. This IP-based storage networking standard enables you to transfer block-level data to hosts using the SCSI protocol. iSCSI links data storage facilities and gives TCP the recovery from packet loss. It also supports network packet encryption and decryption.
