Never used, so I have no idea.
What do you suggest?
And have you got a unit for sale?
Let me know

I have one slot available, it's PCI-X, 64 bit, 66Mhz, 3.3V

I always liked the LSI SAS/SATA controllers. The LSI SAS3080X in particular is fairly cheap and easy to find on ebay. It has 8 internal SAS/SATA ports, but you'll need the appropriate breakout cable(s). There are other models with only external ports or a mix of internal and external, depending on what your needs are. The important thing is the X at the end of the model number to indicate the PCI-X version of the card. There's also a 3080E which is PCI-Express, so stay away from that!

Thanks for your answer.

I need more space, I need to connect two internal hard drives. My HPPA workstation is SCSI UW/DIFF. Since a brand new 150GB SCSI hard drive is listed at 150 euro, whereas a SATA 1TB hard drive is listed at 50 euro, and I need 300GB of space, I am moving to SATA. Fortunately I don't need HPUX, linux is fine, so I have just to find the right controller.

Beware that the older LSI SATA II controllers mentioned here are limited to 2TB disks.

Thanks, it's not a problem for me, bought two disks, of 1GB each :D

What do you think about Marvell 88SX6081?
It should be < 3Gbps, PCI-X 64-bit @ 66MHz
but I believe ~ 100MB/s on each SATA port.

I've had good experiences with the Syba SY-PCX40009. 4 ports, 64-bit PCI (I think 66MHz+). It does 64-bit DMA. Supported by the sata_sil (CONFIG_SATA_SIL) driver (or maybe it's the sata_sil24/CONFIG_SATA_SIL24?). It's about $30 on eBay.

interesting

kernel v4.9.* seems to have interesting sATA stuff under SCSI's kconfig (does it make sense?)
e.g. drivers/scsi/Makefile:obj-$(CONFIG_BLK_DEV_3W_XXXX_RAID) += 3w-xxxx
which points me to 3Ware's stuff

3Ware cards are usually well supported on Linux.
Theses cards are often considered as some of the bests hardware RAID controllers for GNU/Linux or BSD systems.
3Ware supports Linux and provide an opensource kernel driver which has been part of Linux for ages

2. Linux kernel drivers
There are two drivers for 3ware cards:

Driver Supported cards
3w_xxxx 3Ware Eskalad 7000 and 8000 series
3w_9xxx 3Ware Eskaled 9000 series

You should not expect any problems with theses drivers which are known to be mature and stable.
We don't know any current Linux distribution which miss theses drivers so no additional step should be required to get it working.


Does someone confirm it? On Kernels v4.9.* as well ?

These cards exist in PCI-X @ 66Mhz, around ~50 euro , acceptable for me, but I want to be sure it's a good choice.

I am tempted by 3Ware Escalade 8506-4LP

I have some 3ware cards, and I was annoyed by them. They have a BIOS program that sets up the disks, and I wasn't able to use it as a result in my MIPS system.

The SATA_SIL card I recommended had no such problem.

Perfect for my HPPA workstation, going to buy a couple of SIL :D

But let me understand about 3Ware. I don't need to setup raid, I mean in that case it will be soft-raid (done by Kernel).
Can 3Ware be used as "simple" sata interface? What I really need is a fast interface.

The MIPS system I have sata_sil on is a Broadcom BCM91250a.

As far as I remember, I was not able to access any drives on the 3ware card without configuring them in the BIOS program. :(
