SAN Configuration do I really need a switch?

I have 2 Linux Hosts, and a NexStor CR8F array. The array has 2 channels, A and B with DB9 input and output connectors. If all I want to do is hook the two hosts to the array do I need to put a switch in or can I just connect Host 1 to channel A and Host 2 to channel B? I will be using RAW devices for a couple of small files (300 mb) and then handing the rest over to Oracle ASM to manage.

Would it be better to hook Host 1 to input A, cross-connect output A to input B and then hook Host 2 to output B to make a complete loop?

I used the simple Host 1/channel A input - Host 2/Channel B input on a NexStor 18f and it worked fine. Doing it with the NexStor CR 8F seems to cause blocking on the raw devices.

Thanks for any topological help...

Mike
