This iSCSI adapter option uses a new protocol that enables block-oriented storage data to be carried by Ethernet IP networks. It is a first-generation, hardware-based iSCSI Initiatior for IBM eServer xSeries servers to connect to iSCSI target devices, such as the IBM TotalStorage DS300 external storage enclosure. It provides hardware failover and remote boot capability. This option reduces CPU workloads by moving all protocol I/O processing off the host.
