In theory but it will be 3 different subnets and I not convinced it will work unless you bind SM to specific ports.<BR>
<BR>
Initially just have Client1port2 connected to Client2 port2owith a SM on both, no other connections. This should work. After that you can look at adding extra cables<BR>

Hi Richard
Thank you for your information.
SubnetManager
192.168.100.231(port1) Subnet Manager
192.168.200.231(port2) Client1(192.168.100.232)
+----------+ +----------+
| | 192.168.100.0/24 | |
| port1------------port1 |
| port2--+ +-port2 |
| | | | | |
+----------+ | | +----------+

| | Subnet Manager
| | Client2(192.168.200.233)
| | +----------+
| | | |
+-------|--port1 |
+- port2 |

+----------+
It is mean that If I connect Client1 and Client2 directory, and run
OpenSM on client1 and client2
this topolgy would work??
BTW I'm reading
InfiniBandTM Architecture Specification Volume 1 Release 1.2.1 for
study about Infiniband.
CHAPTER 3: ARCHITECTURAL OVERVIEW
It is a bit difficult for me.
I would appreciate If you could tell me more better tutorial
book/website/ml or so on..
