Fibre Channel and iSCSI functions
The Fibre Channel functions include the Fibre security control function and the host group function:
- The Fibre security control function controls the access from specific hosts or specific commands.
- The host group function also enables the storage system to make a suitable response to each host connected, even within the same port, by grouping connected hosts within a port and setting the logical unit mapping and the host connection mode for each host group. You can set up to 255 host groups per port.
The iSCSI functions include the iSCSI security control function and the iSCSI target function.
- The iSCSI security control function controls the access from specific hosts or specific commands.
- The iSCSI target function enables the storage system to respond to each connected host, even within the same port, by grouping the connected hosts within a port and setting LUs and host mode options for each group. You can set up to 255 iSCSI targets per port. Authentication can be performed for each target by using the CHAP authentication concurrently.
NoteThe iSCSI ports do not support fragment processing (dividing a packet). When the maximum transmission unit (MTU) of a switch is smaller than that of an iSCSI port, packets might be lost, and data cannot be transferred correctly. The MTU value for the switch must be the same as or greater than the MTU value for the iSCSI port. For details about the MTU setting and value, see the user documentation for the switch.
