The drive size is added up and then cut in half because of the striping. If they wanted to go Raid 10 they would be losing disk space based on the two 1 TB drives already on the system correct? I have built some RAID 10 before but always with the same drive size.
He currently has a setup of Raid 1 with two 1 TB disks. From what I read it supports Raid 1, 0, and 10. keeping my regular PCIe slots free.Friend of mine has a Dell T310 server with an H200 perc controller. I was even able to put the card in the the normal integrated slot. It just flies right through that part of POST. I'm not sure if you have to flash the SBR and SPD back.

Next, I used a USB DOS disk and the LSI feature pack to get access to all the apps I need to flash (you need both megarec and sas2flash): more than enough to reach the controller in the PCIe slot. I eventually did figure it out, though.įirst off, I was able to finagle some extra slack from the cables behind the backplane. I looked through it, but didn't find anything that helped. which I really don't want to do, as I plan on filling them up with PCI SSDs. If that doesn't work, I'll look into longer cables and sacrifice a PCIe slot. So at this point, I want to get back to the stock H200 firmware and be able to boot off it in the controller slot once again. Even though the ROM says "valid" before the flash, and works fine with sas2flash.efi, it doesn't actually flash (I can't remember the error message. The third post by gwm210 talks about using a USB DOS disk and the Megarec exe to flash the integrated Dell H200 firmware, but Megarec doesn't seem to want to work. I was able to find someone with a similar problem on this page, though with an H700. None seem to be able to boot in the integrated (or is it modular) R710 slot, and I don't have longer SAS cables. I've tried flashing the official Dell H200 adapter, integrated, and modular firmware. The only clue I have to what is going on with that is when I flash using sas2flash.efi, is says something about a mismatch, then writes something to NVRAM. I've read that the R710 flashes *something* to the NVRAM to keep track of the card (?), but clearing NVRAM doesn't help, either. I can boot with the card in a regular PCIe slot, but no matter what I flash to it now, I can't get it to boot in the integrated slot. However, upon rebooting, the R710 was not happy and said an invalid device was in the integrated PCIe slot.įrom there, it gets kinda fuzzy. The led me to the following section.įollowing the instructions on this page, I cross-flashed the H200 to an LSI adapter with version P20 firmware.
Dell perc h200 raid modes driver#
Additionally, when I booted into FreeNAS, it gave me an error that the firmware version (7) didn't match the driver version in FreeNAS (20). Well, for whatever reason, the H200 I purchased did not show a JBOD option.
So I bought an H200 off Ebay, which was recommended for its JBOD feature. The R710 came with an Perc 6/i, which according to the FreeNAS gurus, is not ideal due to the fact that it can't pass through the drives directly to the OS, which is best practice when using non-RAID systems like ZFS. Lots of good info in the forums here, but I haven't been able to find anything that can get me out of the boat I'm in.īasically, I have an R710 running FreeNAS 9.3.
