Would anyone happen to know a good cheap controller that supports both Ubuntu and Opensolaris?
raid is not an issue seeing as how I would use either ZFS and a Z-raid or a software raid under Ubuntu,
I need to be able to support 8 disk which means I could use multiple cards or a large one such as the Supermicro AOC-USAS-L8i.
The motherboard I would use has 2 x 16xPCIe slots and a 8xPCIe slot and a couple of 1xPCIe slots.
As mentioned above I have looked at the AOC-USAS-L8i but cannot find if Ubuntu supports it definitively and would not like to build custom kernel modules if possible.
It has Mini-SAS connectors which is just a simple way to have two big cables go to 8 SATA connectors without too much cable hassle. So its just a 8x SATA/300 PCIe x4 controller.
Best of all, it supports Staggered Spinup, so having many disks in a PC won't require you to have a 1000W power supply. As each 3.5" disk consumes about 30-35W when spinning up, this can get you into power problems with more than 10 disks spinning up all at once - like when ur powering it on. It might just as well power off one second later as a safety mechanism by the power supply. Using staggered spinup resolve this issue as the disks won't spinup at exactly the same time but is more spread evenly to give the PSU a break.
Only the case connector is UIO the bus is standard PCIe and will work with any PCIe slot.
Furthermore I know that the card is compatable with Redhat and Suse but I am much more familiar with Ubuntu and would like to continue using it or at least deibien.
Many opensolaris forums suggest the card for a cheap controller.

Tech Level Tech Level: high - Ownership: 1 month to 1 year
Pros: Works great for RAID10 with 4 Western Digital 1TB RE3 drives with the appropriate fan-out SATA cable.
Cons: NOT INTENDED FOR ANYTHING BUT SUPERMICRO BOARDS. The board connects to the UIO expansion of specific Supermicro Boards and will not work with ANY other brands in a PCIexpress card. NOT REALLY A CON... if you have a board that uses it.
Did you find this review helpful? Yes No
Thanks for the valuable feedback you provided!
Non-standard form factor

This user purchased this item from Newegg
Pros: Specs were good... 8-port SAS and 8x PCI-Express.
Cons: Super-Micro specific form factor? All of our machines, even those with server mobo, are incompatible with this card. Look closely at the pictures - the card form factor is mirror-image of a normal card.
Other Thoughts: Super-Micro has a list of compatible mobo and they are all Super-Micro mobos. I thought this was just the "tested" list but apparently they really mean it.
Im having a hard time understanding how the hard-forum posts are not convincing you of the fact that it works considering the pictures and multiple people's posts with clearly standard hardware such as an ABIT IX38 Max

I bought the AOC-USAS-L8i and recived it yesterday. Both opensolaris and Ubuntu recognise the contorller and load drivers for it.
However I have not had a chance to test the card due to the fact that the card does not recognize the drives that I have.
