Well now I have
actual enterprise SAS drives running on a hardware RAID controller on a Raspberry Pi,
and it s faster than the fastest SATA RAID array I set up in that other video.
A Broadcom engineer named Josh watched my earlier videos and realized the ancient LSI card I was testing would not likely work with the ARM processor in the Pi, so he was able to send two pieces of kit my way:
A Broadcom-designed reference Universal Backplane following the SFF-TA-1005 standard
After a long and arduous journey involving multiple driver revisions and UART debugging on the card, I was able to bring up multiple hardware RAID arrays on the Pi.
