Connectivity

This information lists the number of Fibre Channel and Ethernet (iSCSI) ports that
are available in fully and partially populated racks.
The maximum number of iSCSI host ports that can be logged-in concurrently is
700 per interface module. The maximum number of Fibre Channel (FC) host ports
that can be logged-in concurrently is 350 per target port and 700 per interface
module. However, the limit of 700 per interface module includes FC and iSCSI
host ports logged-in concurrently, and mirror connectivity. The per system limit is
1400 concurrent port log-ins for a six module system and 2000 concurrent port
log-ins for nine or more module systems (including FC, iSCSI and mirror
connectivity). This applies to XIV Gen3 microcode version 11.1.1 or later.
The following table lists the number of Fibre Channel and iSCSI ports and
identifies the interface modules from which Fibre Channel and iSCSI ports are
available for each module configuration. For XIV systems with 1 Gb Ethernet
ports, interface module 4 has four Fibre Channel ports and two Ethernet (iSCSI)
ports. Interface modules 5 - 9 have four Fibre Channel ports and four Ethernet
(iSCSI) ports each. For XIV systems with 10 Gb Ethernet ports, all interface
modules have four Fibre Channel ports and two Ethernet (iSCSI) ports.

Notes:
1. Fibre Channel and iSCSI ports on module 6 are not active in configurations of 12 or
fewer modules.
2. Fibre Channel and iSCSI ports on module 9 are not active in configurations of 10 or
fewer modules.
3. On interface module 4, only two of the four available Ethernet ports are used.
