Iscsi Adapters; Fibre Channel Adapters - IBM Power 720 Overview

2.7.7 iSCSI adapters

The iSCSI adapters in Power Systems provide the advantage of increased bandwidth through
hardware support of the iSCSI protocol. The 1 Gigabit iSCSI TOE (TCP/IP Offload Engine)
PCI-X adapters support hardware encapsulation of SCSI commands and data into TCP, and
transports them over the Ethernet by using IP packets. The adapter operates as an iSCSI
TOE. This offload function eliminates host protocol processing and reduces CPU interrupts.
The adapter uses a small form factor LC type fiber optic connector or a copper RJ45
connector. Table 2-16 lists the orderable iSCSI adapter.

2.7.8 Fibre Channel adapters

The systems support direct or SAN connection to devices using Fibre Channel adapters.
Table 2-17 provides a summary of the available Fibre Channel adapters. All of these adapters
except FC 5735 have LC connectors. If you are attaching a device or switch with an SC type
fibre connector, an LC-SC 50 Micron Fiber Converter Cable (FC 2456) or an LC-SC 62.5
Micron Fiber Converter Cable (FC 2459) is required.
