P2000 G3 SAS Dual Controller and 2 Dual Ported HBAs

Hi,

 

I have a DL380 server with 2 Dual ported SAS HBAs. I also have another server with  1 Dual ported SAS HBA.

Looking at the cabling guide for the P2000 G3 SAS, it does not mention or show how to connect a single server with 2 Dual ported HBAs to the P2000 G3 with dual controllers. Is there a specific port assignment I need to use?

 

The P2000 SAS controllers go from left to right as SAS1 SAS3 SAS2 SAS4

So mine looks like this

CntrlA SAS1 | CntrlA SAS3 | CntrlA SAS2 | CntrlA SAS4  --  CntrlB SAS1 | CntrlB SAS3 | CntrlB SAS2 | CntrlB SAS4

 

I know to connect  port 1 and port 2 on the HBAs to controller A and B for redundancy. However with 2 Dual ported HBAs on the single server I am not sure if I need to use any specific SAS port pairs on the controllers..eg... 1 and 3 or 1 and 2.. This is how I plan to lay it out.

 

Server 1

HBA1 Port1 = CntrlA SAS1(1st from left controller 1)

HBA1 Port2 = CntrlB SAS1(1st from left controller 2)

HBA2 Port1 = CntrlA SAS3(2nd from left controller 1)

HBA2 Port2 = CntrlB SAS3(2nd from left controller 2)

 

Server 2

HBA1 Port1 = CntrlA SAS2(3rd from left controller 1)

HBA1 Port2 = CntrlB SAS2(3rd from left controller 2)

 

Does this look OK?

 

Again, the cabling guide or installation guide does not mention connections with 2 dual ported HBAs in a server.

 

 

Thanks

Hi,

The cabling manual is not what you need.

HP P2000 G3 SAS MSA System User Guide
http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c02254382/c02254382.pdf
Page 38

And i think It is necessary to use same Server HBA configuration on both servers.
