Does the iSCSI solution support direct connect (no switches) between iSCSI HBAs?

Yes, with IBM I 6.1, a switch is not required between the iSCSI HBAs for simple one-to-one configurations. For more complex configurations and for prior releases, a switch is required between the iSCSI HBAs. See the Ethernet switches for iSCSI page for details.

Yes, with IBM I 6.1 or later, a switch is not required between the iSCSI adapters for simple one-to-one configurations that use an IBM I iSCSI hardware target (iSCSI HBA). For more complex configurations, configurations that use an IBM I iSCSI software target (Ethernet NIC), and for I 5.4, a switch is required between the iSCSI adapters. See the Ethernet switches for iSCSI page for details.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
