This server will support  a maximum of 2 internal controllers and one external controller; You can find more information here in the techinical guide:

Ok, so there is no limitation like 'given backplane and be connected to only one controller'? My concern was not having multiple controllers, I was concerned about connecting both controllers to the same backplane.

thanks

Hi,

Was it possible to use to cards on the same backplane ?

thanks 

Hello,

yes you can connect one perc on SAS A connector and the other PERC on SAS B connector.

Thanks

Hi Marco,

Thanks for the answer.

Just to be precise I will add DELL 9260-8i card in addition to PERC h710. And I have 12 LFF backplane.

Will the first card occupy the first 6 slots and the second one occupy the rest ?

Regards,

Mnd 

Mndshayeb,

There is a couple issues with that. The first issue is that the 9260-8i isn't supported on the T620, and the second would be that the T620 only supports dual controllers on the 2.5in drive configuration.

Let me know if this helps.

OK. May I know what is the use of two SAS ports on the backplane ? Is it for multipathing ? 

Hello,

yes it is for redundancy.

Thanks

Marco

Thanks Marco.Any document explains what kind of redundancy is provided ? I would like to know more about it.

Cheers,

Mnd

Thanks Chris 

I am not seeing anything in the documentation. Let us look into it for you and we will let you know what we find.

Hello, I'm sorry but i confirm there is no public documentation about backplane redundancy.

Thanks

Marco
