Obviously connecting them to the JMB is better. Title updated to “32 to 2 ports”: Any idea if the card is compatible out of the box on Ubuntu SMART only makes it worse. So far lscpi and lshw see the card but the one drive I have connected for testing isn’t showing up. Actually really interesting breakdown, thank you for your work on this.

The array assembles without problems. I tried to find a minipcie or expresscard, like in Sonnet one SAS adapter and only found the Sonnetto one. It was very helpful in finally finding the right solution. Download the firmware to a Windows PC, unzip the download and copy the 3 files it contains Product Pricing Community Blog.

The data can be recovered by putting the disks in any lijux. Sign up using Email and Password. I can’t determine where the kernel module is coming linjx. Never thought of it. HP has a 36 port one that is said to be quite good, gives 32 disk capacity.

From 32 to 2 ports: Ideal SATA/SAS Controllers for ZFS & Linux MD RAID

Hi, Here is my experience. I managed to get driver sources for the 2. This is the only 4-port SATA controller supported by Linux providing acceptable throughput to each port. This possibility was for me one of the main points for choosing a software RAID. I’ve build out plenty of desktops, some workstations and servers so I’m comfortable with the hardware end of the build.


It seems to work very well.

Seems to have an LSIE chipset. That is not possible with mpt2sas drivers up to version No wait, I think I see what you mean now. But can you or anybody reading these comments confirm whether the blocking SCT commands affects behaviour when a read error actually occurs?

From 32 to 2 ports: Ideal SATA/SAS Controllers for ZFS & Linux MD RAID

I called Supermicro and they state that the drivers aoc-sa2lp-mv8 the card need to be loaded into unraid. Supermicro HBA based on this chip: Also, first boot in my GigaButt board was a no,no.

Do they use their own chips? However, beware, this chip does not support drives larger than 2TB.

It is a great summary and interesting to see that there are aoc-aas2lp-mv8 a handful of “real” chip vendors the board makers are abundant. I thought that would be the case, just wasn’t sure if the controller was added when the article was written or it is was updated more recently.


I’ve already had my pair of boards The commit notes are here: For those that like to live dangerously, dealextreme sells dodgy second tier QA castoff LSI s and s for pretty cheap. Kind of annoyed at Supermicro You might imagine that Aoc-ssas2lp-mv8 want to keep the array as save as possible now and also avoid another useless buy.

This is called up-plugging by the PCIe standard. Also, everything works fine on Win7, so the hardware is ok. OpenSolaris ahci driver does not support that chipset yet.

Our RR64x series, for example, support PM capable enclosures and chassis.
