Hi,

I'm not much into storage and RAID so i got couple of questions. Is there any other functionality to two connectors in a SAS backplane beside redundancy? Which RAID controller is recommended for Dell Power Edge R310 to achieve hardware RAID, and which cable needs to be used to connect that controller to the backplane and how.

Thanks.

All of the main RAID controllers available from Dell will work.  Note that the controllers in the list with S in front is for Software RAID, H for Hardware RAID.  The PERC 6 is a hardware RAID controller.  So is the SAS 6, but it is much lower in performance and features.

Sorry ... if you check that link, the H700 and the H200 (and SAS 6/iR) are the only supported hardware RAID controllers for the R310 (I was looking at the T310).

The two SAS connectors are not for redundancy ... they are for multiple channels.  Some multiple RAID array configurations are best configured on separate channels for performance.

Hi,

Thanks for the clarification, i would also like to know which cable do I need to use (is supported) if I am using SAS 5/iR or SAS 6/iR cards.

Those are a little more difficult without a parts matrix (or having one yourself, which I don't) - I would call Dell's support to ask for a part number for that machine.

Would be easier if you could use Google Images to see a picture of it to see if there were 4 or 8 or 12 disk bays and make an educated guess as to whether there is a SAS expander and multiple paths but Dell have that stupid plastic grill on the front of all the pics of their servers.

I'm not sure that would be easier than calling Dell ... they'll be able to look it up within minutes.

Also, the R310 only supports 4 drives.  Hot-swap was also optional, so you would need to know if the drives are cabled or attached to a backplane.

If attached to a backplane, it will look something like this (not saying this will work):

If cabled, it will look something like this (again, not saying this is the one you need):
