If you are expanding the existing arrays, you will need to use 15k SAS drives. Mixing different speeds of drives in a single array will lead to strange results - at best, everything will slow down to the speed of the slowest drive. NLSAS drives are basically 7.2k RPM SATA drives with a SAS controller on the drive, so they are much slower. If you are ...

Well, there is a reason Dell writes a comprehensive technical guide for these kind of systems: To answer that kind of question. See http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/dell-poweredge-r510-technical-guide.pdf Spoiler: It supports only one full length card.

The DELL PERC H730 is based on the LSI 3108 Chipset, and since this chipset supports disks larger than 2TB and SAS3 communications I can't see reasons for this controller won't work with those Seagate NL-SAS 4TB discs. What you should consider is the cabling used on this card, since SAS3 cards uses the new SFF8643 connector.

After a lot of going back and forth with Dell, pulling out the iDRAC Enterprise, the problem was isolated to a faulty iDRAC Exress card. Found a replacement for £30 and once replaced, everything is running as it should.

What specific errors are you receiving? I would recommend trying to get some more information from the PERC controller. With Ubuntu, you may not be able to install Dell's OMSA for monitoring and management. You could likely install MegaCLI and use it to export a controller log to get more info on events that are occurring. Is there a reason you haven't ...

Can you see the SMART information for the individual disks via the Disk Utility? Look at the Pre-Fail checks & see if anything stands out. This will indicate a failing physical device. Is the disk that's producing the errors in a RAID group with other disks? If not it may be the file system and not the drive or, depending on the layout, could be the ...

You have one drive in a RAID that is misbehaving, and producing occasional errors? Sounds like a hardware problem, and one that is likely to get worse. You should consider replacing the drive. Yes, it's expensive, but how much is your time worth, and how bad would it be if the entire drive went south at an inopportune moment?
