Could you please point out the intelligent, hardware RAID card that
Promise makes for PCIe? Or do you mean "dumb ATA channels with a 16-bit
only BIOS" (and 100% driver RAID) aka what I call "FRAID" (fake RAID)?
FRAID is not feasible with Linux, it never will be. It's better to use
the "dumb ATA" channels with MD/LVM. But I'd much rather have an
intelligent, hardware RAID solution.

Let me guess, High Point Technologies (HPT) or Silicon Image "FRAID"?

That's LSI Logic. Don't reuse the product as a vendor.

Products? I've seen a _lot_ of "dumb ATA" channels that do FRAID.
Nothing intelligent.

Everything I've seen is FRAID -- "dumb ATA" with 0 intelligence on-
board. I would be interested if you've found something else though.

FRAID. That's _not_ hardware RAID.

Yes, and use software RAID. I want intelligent, hardware RAID.
I've got *1* product choice, the LSI Logic MegaRAID 320-2E.

I want intelligent, hardware RAID in PCIe. I know only 1 product.
If you know more, please tell me. But don't tell me about FRAID.

Then you've never used a 3Ware Escalade 7000/8000 64-bit ASIC product or
an LSI Logic MegaRAID "X" series Intel XScale microcontroller product.
Besides, pushing _all_ I/O over a _single_, _shared_, _legacy_ was _not_
viable back in 2000, let alone now (5 years later).
I used to specialize in ripping out i440BX/GX chipset mainboards and
putting in ServerWorks ServerSet IIILE and IIIHE chipset mainboards for
$500-750 and companies would instantly see 3x the performance with their
_existing_ RAID controllers and GbE cards. And that was circa 2000.
