nvidia raid

Is it generic?

If I set up a RAID 0 on a nForce 570 Ultra, could the RAID be
recognized by the nForce 590 chipset on another board?

A very good question... unfortunately I don't know. I never personally trust
RAID between different chipsets...

Linux has a software driver foir this type of fake-RAID, called dmraid.
It may document whether the on-disk format is the same. However since
both chipsets are really RAID capable and the RAID is done in software
there is a good chance this may work.

Nothing to do with the chipset at all.
Any chipset is RAID capable, it's just a question of BIOS and drivers.

and the RAID is done in software

Like there is any difference if it was to be hardware assisted raid, babblebot.

Because it's both nVidia and they are the original creators (no OEM).

Why is it fake RAID?

Why is it fake RAID?

Because it is not hardware RAID, but pretends to be.

Babblebot, utterly clueless as always.
Because it is not hardware RAID, it doesn't need to pretend to be.
It just is Raid, whether that's firmware or hardware assisted.

Are Lunix freaks really so stupid? It is software RAID, it does not pretend to be anything else.

It calls itself a raid controller. It pretends to be a hardware controller
no matter what assinine assertions you may blather.

Verily I say unto thee, that Eric Gisin spake thusly:

Ignorant twit.

Fake-RAID is an implementation along the lines of other half-assed
hardware solutions, like Winmodems. Some (but *not* all) of the
functionality that would otherwise be in hardware is shifted to the OS
via drivers, thus reducing the cost of that hardware by 0.00001 cents
per unit (presumably).

Purely hardware RAID requires no drivers (other than (S)ATA/SCSI), and
is thus OS agnostic.

Software RAID is something else yet again, and does not actually require
anything but two or more hard drives (no special controller), since as
the name suggests, it is implemented purely in software.

Linux Software RAID can be set up using a tool called mdadm.

Fake-RAID (i.e. Intel ICHx) can be set up using dmraid.

Hardware RAID (e.g. certain cards from 3Com) just works. It also tends
to be a quite expensive (and arguably better) solution.
