July 10, 201114 yr LyCom ST-126 SATA II 3Gbps 1-To-5 Port Multiplier PCI Low Profile Host Adapter. http://www.lycom.com.tw/st126.htm around 55 € over here maybe a bulk buy direct from Taiwan can make them a lot cheaper? a few questions? * Could This work with Unraid ? You dont even have to sacrifice a Pci-E slot. * Does anyone has something like this running with UnRaid? (particular this one , or similar card ) * Doesn't this slow everything down? now 5 HDD on 1 sata port? Update: Seems that Addonics also has some of these SATA Multipliers http://www.addonics.com/products/host_controller/ad5sapm.asp
July 12, 201114 yr I've heard of these port multipliers working with unRAID, but I don't remember specifically which models. Really no way to tell with this one without just trying it. I see nothing to indicate that it won't work.
July 13, 201114 yr I suspect the more important question to ask would be "Could this work with my SATA controller?" After quickly reading up on the subject, the controller needs to support port multipliers and many controllers cannot. Two informative links I've found: http://en.wikipedia.org/wiki/Port_multiplier https://ata.wiki.kernel.org/index.php/SATA_hardware_features If the controller supports it, I would imagine UnRaid can work with it too as it appears to be transparent to the OS. I expect FIS-support to be pretty much a requirement and even then, performance may suffer badly, possibly depending on the number of drives attached.
July 13, 201114 yr Author Thnx,, more if if 's i see,, too much chance of not working when you don't have the right controller. the wikipedia links answers almost every question i had. sharing the bandwith,maximum 15 drives on 1 onboard sata port,, etc etc i wil keep it in mind for a drive upgrade-solution when there is no other options to upgrade trough pci-e x1 , x4 ,x8 or x16
