Perc 310 and I7-3930K C2 and Sabertooth X79?

1. Maybe. Dell designed the H310 to work in specific Dell servers and workstations. Using it in another system is in no way supported, nor was it ever intended to work in another machine. That doesn't mean it won't work, simply that it is going to be a matter of trial and error and is completely up to you to try and troubleshoot any issues that may arise.

2. The H310 supports RAID and non-RAID, and they can be mixed (but are NOT compatible, meaning if you configure a disk as non-RAID, you cannot convert to a RAID configuration later without data loss).  There are issues with RAID 5 on the H310, so I would recommend against that RAID level on it.

3. 3TB and 4TB drives are supported on the H310 with the latest firmware.

4. Yes, two cables, each supporting 4 drives.  They can be SAS or SATA - you just have to have the right cable(s).  You need an SFF-8087 to multiple SFF-8482 for SAS drives (will also work for SATA drives), something like this:

"I don't want to buy it and get stuck with a product I can't use"

Are you buying an H310 for this project, or do you already have one that you want to use?  If you want to use it because you have it, then go for it - there are just no guarantees that an OEM product will work in a system other than the ones for which it was designed.  However, if you don't already have one and are looking to purchase one specifically for this project, then I would suggest buying a generic/retail controller - like an LSI controller similar to it (or one that specifically meets your needs), then there is no reason to wonder if an OEM part will work (although, as with any parts, sometimes there may be incompatibilities, but they are far less likely/common).  What are you looking for in a controller?  What system are you looking to use it in - custom built? another OEM?

All your questions are answered in my previous posts and title. Asus Sabertooth X79 with i7-3930k cpu. I already mentioned LSI..M1015 which is basically an LSI..can be LSI 9240 or 9211 from what I read. I am looking to buy of course otherwise I'd just try it if I had it.

Many people ask these types of questions having already tried it without it working - or don't dare try.

There remained some ambiguous details, which is why I asked, but if you have a handle on this, then I'm not sure you need to answer.  Good luck.

theflash1932: sorry, one more thing if you can answer with certainty. You said the H310 can support 3 and 4TB drives with latest firmware (from Dell I assume). But according to this link it looks like only 2 TB will be recognized.  Have you actually used a 3 or 4 TB drive with this card? Or do you have another link that confirms you're right?

Do you know if only SAS drives are 6gps? From what I read in the specs it mentions 6gbps but for SAS only. So it seems like it's 3gbps for SATA drives?

No, SATA also comes in 6Gbps.  SAS 2 and SATA 3 are 6Gbps.

That doc predates all 12G controllers (PERC 8 family:  H310, H710, etc.), and the H310 replaced the H200, which supported 3TB and 4TB drives with a minimum firmware level.  That said, there is no explicit mention in any of the docs I could find, but the main reason I say they will work is that fact that you can configure a 12G server with an H310 controller and 3TB and 4TB drives on Dell.com ... the configurator throws a fit if you were to add drives with a controller that does not support them..
