hello there,

in this configuration you are going to need 4 * server connections on
the ds4300. When you create your arrays and luns on the ds4300 you are
going to map them to the mac addresses of the hba's on the servers.
This term is LUN masking.

A better scenario, and for scalability would be to connect the servers
to fibre switches then connect the switches to the ds4300. You would
then zone the switches, hba and port on the ds4300

ie,

hba 0 --> port 0 on switch 1 --> controller a --

----- lun0
hba 1 --> port 1 on switch 2 --> controller b --

You would then use rdac on aix that would create 1 dar (disk array
router) and 2 dacs (disk array controller). This would present you lun0
with 2 paths

HTH
