node

Host Connectivity (Fibre Channel )
Max FC Initiators per InServ 768 1024 1024 1024
Fan-Out (Max initiators (host HBA ports) per InServ port over SAN)
NOTE: This limit is an aggregate of the total iSCSI and/or FC initiators

Host Connectivity (iSCSI)
Max iSCSI Initiators per InServ 256 1024 1024 1024
Max Dual-path iSCSI Linux hosts per InServ with Open-iSCSI initiators
128 512 512 512
Max Dual-path iSCSI Linux hosts per InServ without Open iSCSI
initiators (Each iSCSI Linux initiator visible to a single InServ port = 2
initiators; Linux host with 1 iSCSI initiator that is visible to two InServ ports
via IP network is equivalent to dual-path Linux host and counts as 4
initiators)

Max Dual-path iSCSI Windows hosts per InServ (Each iSCSI Windows
initiator visible to a single InServ port = 1 initiator; Windows host with 1
iSCSI initiator that is visible to two InServ ports via IP network is
equivalent to a dual-path host and counts as 2 initiators)

Fan-Out (Max iSCSI initiators per InServ port over IP network; each Linux iSCSI
initiator counts as two iSCSI initiators on the InServ)

Host Connectivity Limits
Note: Host connectivity limits for configurations with Vmware ESX servers are limited to an aggregate of 32 host initiators fan-out per 4Gbs InServ port
and 16 host initiators fan-out per 2Gbs InServ port. This separate limitation applies to all InServ models and node configurations. Please refer to the
VMware Implementation Guide for further details.
