MSA 2000fc direct connect

Hi All,

We want to connect one server with 2 HBA to the MSA 2000fc using direct connect without fibre channel switches.
If there some problems or bugs when using direct connect?

BR,
Max

Hi Max

One server, 2 * HBAs connect fibre cables to P0 on both controllers ( the ports on the left)

Is there any HBA settings when using direct connect?

Re: MSA 2000fc direct connect

What about multipath drivers? Does it works in direct connect configuration?

Re: MSA 2000fc direct connect

In the QLogic adapters, "point to point" refers to Fabric switch connectivity - you need to select 'loop' for FC_AL protocol.

Re: MSA 2000fc direct connect

I' confused about following: in MSA 2000fc cabling guide host must be connected to the P1 ports on each controller, but in the MSA 2000fc user guide host must be connected to the P0 ports on each controller and i don't know where is correct solution. (please see attachment for details)

I'd say that both are 'correct' examples.

Can you give me the document and page numbers so that I can check the context, please?

Re: MSA 2000fc direct connect

Hi Max

Just checked my documents Uwe is correct on the Direct attach sorry for my error earlier.

My details say for the MSA2000fc Direct Attach via FC-AL or Private Loop.

Both cabling concepts are correct, my details are as follows:

One server, dual HBA use P0s

Two servers, first server use the P0s, second server use the P1s

for mulitple hosts single paths: (Max of 4 servers)
Server1 P0 Controller B, Server2 P0 Controller A, Server3 P1 Controller A and Server4 Controller B port1
