    iSCSI GbE to SAS/SATA RAID Subsystem 3.6 iSCSI Introduction iSCSI (Internet SCSI) is a protocol which encapsulates SCSI (Small Computer System Interface) commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. iSCSI provides high performance SANs over standard IP networks like LAN, WAN or the Internet.
  • Page 58 iSCSI GbE to SAS/SATA RAID Subsystem The host side needs an iSCSI initiator. The initiator is a driver which handles the SCSI traffic over iSCSI. The initiator can be software or hardware (HBA). Please refer to the certification list of iSCSI HBA(s) in Appendix A. OS native initiators or other software initiators use the standard TCP/IP stack and Ethernet hardware, while iSCSI HBA(s) use their own iSCSI and TCP/IP stacks on board.

    iSCSI GbE to SAS/SATA RAID Subsystem 6.8 MPIO and MC/S These features come from iSCSi initiator. They can be setup from iSCSI initiator to establish redundant paths for sending I/O from the initiator to the target.

Hence, all MPIO infrastructures are shared among all SCSI transports, including Fiber Channel, SAS, etc. MPIO is the most common usage across all OS vendors. The primary difference between these two is which level the redundancy is maintained.
