We are setting up FAS3240 on 2 chassis with IOXM, which will be connected to both DS14 FC/SATA and DS4243 SAS disk shelves. SAS ports are enough and it's the FC ports that giving us issues as:
1. we were planning to use the 4 onboard FC ports to connect to the DS14 shelves: 1 pair to DS14-FC and the other pair to DS14-SATA
2. the FC HBA in expansion slots will then be used as target
However, we did not realize that the cluster interconnect between the chassis will be using up the 2 onboard FC ports so that we have only 2 onboard FC ports left to connect to the DS14.
Can you advise:
1. whether it is possible to configure the other FC ports in the expansion as interconnect between the chassis?
2. if not, whether it is an advisable option to go single path to the DS14 - 1 port to the DS14-FC and the other to DS14-SATA?
Thanks for your comments
