Our new NAS has four network ports that are linkable and I would like to utilise that extra potential capacity.
1 - create an iSCSI volume, with its lower overhead, connect the main file sharing server to that volume then reshare via SMB and group policy to mapped drives for the users? Issue I see with this is I wont be able to utilise the extra network capacity of the linked lan ports on the nas as all the sharing is going through the one file server which will create a bottle neck with its own single lan port. As its a local drive to the server I can more easily do various operations like backup/moving/searching etc etc
2 - create the SMB shares directly on the NAS and point the user mapped drives there which will theoretically allow all users to go through the 4 linked ports increasing potential bandwidth.
