P2000 G3 SAS cable settings windows clustering.

Hi,

 

i am wundering on  how we shuld set up the cables betwen the p2000 and the servers when we plan to use Winodws 2008 active/passiv clustering

 

the p2000 has 4 ports on controller a 1-1, 1-2, 1-3 , 1-4

and 4 ports on controler b 2-1, 2-2, 2-3, 2-4

 

Shold the first server be connected to 1-1 and 2-1 and the secound server be connected to 1-2 and 2-2?

is there a resone why we should not connect the first server to 1-1 and the second to 2-1?

if we use 1 controler on 1 server we can connect 8 servers if we use 2 controlers on 1 server then we can connect 4 servers

Hello,

AFAIK you can technically connect the servers anywhere you want.

HP may have some recommendations (or maybe even requirements?) in regards to which setups they support etc.

I believe the idea is to have same port going to the same 'place' - be it server in your case or switch. If you know that port 1 on both controllers go to the same server (maybe server1?) then I believe that getting an understanding of the cabling/setup is quicker.

Wouldn't you want to use two SAS connections/server for redundancy?

Re: P2000 G3 SAS cable settings windows clustering.

HP actually has some great documentation on this with diagrams etc;

 

"HP P2000 G3 MSA Systems Installation Instructions"

 

In Basic:

Server 1 port one to MSA controller A port one, Server 1 port two to controller B port one

Server 2 port one to MSA controller A port two, Server 2 port two to controller B port two

 

See attached.
