****** - Verified Buyer
4.5
I have an 8i LSI controller card attached to this HP expander card and both worked with Ubuntu 12.04 without any effort on my part - raid 6 via mdadm. I haven't yet used dd to verify the maximum throughput, but with eight disks it is able to saturate my gigabit network wth the CPU nearly idle. I don't know what I'd do without ths card.UPDATE: I *almost* want to take a star off because the firmware is NOT upgradable unless you also have one of several HP branded RAID cards. And you can guarantee that you won't have the latest firmware on the card when you receive it.
