SATA II PCI "Extender"

Hi,

I would like to make a home made backup server and if someone already used something like a PCI express card to extend the number of hdd’s supported in a single box it would be great to know what exact model was used.
I would like to know from someone with experience on this matter what is the best/more suitable PCI-Express model.
There is no need for a RAID controller, the idea is to get away from expensive solutions like 3Ware, LSI, and the like.
I want a simple card to plug more disks on a single motherboard.

I already checked the HCL but it seems to me quite incomplete … there must be more out there that run great on OpenSuSE …

So the idea for my server is to have a Software raid machine. There is no need to make a very expensive raid controller …

Any ideas on this?

Regards,
Pedro

Which one (brand and model) do you have in mind?

A modern kernel shouldn’t have any problem with sata cards (pci, pci-x or
pci-e based).

Anyway, you can take a look into “libata” status:

Hi,

I am asking for an exact Brand and model for a PCI-express card that must be Linux compatible and not expensive.
Not expensive as in the likes of those RAID controllers from 3Ware, LSI etc … (200+)

I want to make a Software RAID, I do not need it to be Hardware-based.

I checked the link before, but googling around proves that some cards, although compatible, will have some issues.
That is why I ask for a model that is truly plug and play in what concerns OpenSuSE 11.1.

For example I have a PC with an on-board controller AHCI form Intel.
No problems there.
What brand and model does have a PCI express SATA II 4 port Intel AHCI controller in the market ?

Or any other for that matter …

Because it is easy to find the driver compatibility … Serial ATA (SATA) on Linux
But sites that describe the PCI-express cards (online stores) do not show the internal chipset they have … some have a vague reference as in “Linux compatible” …

I could find for example a cheap HighPoint - PCI-Xpress SerialATA2 HighPoint 2300 RAID
But even that is around 150euros … too expensive.

Is there something in the order of 100 Euros / 100 US$ that can be used as a SATA II 4 port pci-express card with zero issues on OpenSuSE?

There are plenty of them in the market but their availability depends on
your country and your needs. The only you have to be aware of is about the
real chipset the card is using.

Software raid doesn’t need an independent controller, you can go with the
motherboard sata ports (if any).

O.k. :slight_smile:

AHCI has nothing to do here. If you want a PCI-e SATA card, you will use the
card ports, not the board’s ones.

Once you got a model you like (by prize and specs) then you have to perform
a bit of digging about the chipset…

What I do is going to NewEgg’s site (or any other megastore you know) to
find a brand and model (using filters) that fit my requirements. Then go to
the manufacturer’s site to check the chipset of the card and then look for
the status in the kernel of the driver :slight_smile:

Hope someone can tell you a more specific info.
