Ooh, a few multi-port cards and then some port expanders. Backblaze are up to 60 drives in a box ! https://www.backblaze.com/blog/open-source-data-storage-server/ Simon ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Binding the driver is a matter of simple `echo` to the file in sysfs. See this article: https://lwn.net/Articles/143397/ and examples for PCI devices at https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-bus-pci Providing _exact_ parameters to use is not possible at this time. Only after you have the card in your computer you can use `lspci` to check for exact bus address. > The AHCI driver lists the ASM1062 and also the ASM1062 with the JMB575. > There is no listing for the 1064 or the other two newer chips. > Does this mean that I might have issues using this card? I don't expect any problems, but without the card we can't be 100% sure. I suggest you should buy the card from the place with reasonable return policy. And return it if you can't make it work. -- Tomasz Torcz 72->| 80->| to...@pipebreaker.pl 72->| 80->| ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

In inverse order: This particular chip '1064' is not listed in the pci.id directory although the company is. Will that cause problems for my use? Binding the driver to the card does not look at all straightforward. If this is something that I would need to do - - - - would I be able to get assistance (please)? Reading in ASMedia Technologies web site. in ascending order: 1061 - - - 2 ports 1062 - - - Gen 2 x 2 (pcie) - 2 ports 1064 - - - Gen 3 x 1 (pcie) - 4 ports 1164 - - - Gen 3 x 2 (pcie) - 4 ports 1166 - - - Gen 3 x 2 (pcie) - 6 ports The AHCI driver lists the ASM1062 and also the ASM1062 with the JMB575. There is no listing for the 1064 or the other two newer chips. Does this mean that I might have issues using this card? Greatly appreciating the gentle introduction to the arcane arts of 'under the hood tinkering' (!!!). Thank you greatly for your assistance.

There is only some $20 difference or so from some of the 8 port cards to this one. There are drivers mentioned for Windows but I can't find anything when I'm searching for linux + PCIe + card + SATA controller + drivers + ASM 1064 so thought I would tap the community to find answer(s).

But, in principle, no, you do not need any special driver to use a ridiculous number of SATA ports, or disks with any sort of connection. I have a machine with a motherboard having 6 SATA ports, into which are connected one SSD and five HDDs; it also has two USB3 ports into which are plugged two Fantec 8-drive external cabinets, each containing 8 SATA disks, so the total range of my /dev/sdX devices is /dev/sda to /dev/sdv. The standard (Beowulf at present) kernel just handles this fine. I can do MD- RAID and LVM2 (and also both) with the devices with no problem. Many years ago I did the same sort of thing with IDE - I had PCI cards with two IDE connectors, each connector capable of two devices each (master + slave), and I could build machines with four such cards in (so, 4 x 2 x 2 = 16 drives in total) again without doing anything special to the kernel.
