I have been using an older 64bit system, socket 754 for a while now. It has the old PCI bus 33Mhz. I have two low cost (no HW RAID) PCI SATA I cards each with 4 ports to give me an eight disk RAID 6. I also have a Gig NIC, on the PCI bus. I have Gig switches with clients connecting to it at Gig speed. As many know you get a peak transfer rate of 133 MB/s or 1064Mb/s from that PCI bus http://en.wikipedia.org/wiki/Peripheral_Component_Interconnect The transfer rate is not bad across the network but my bottle neck it the PCI bus. I have been shopping around for new MB and PCI-express cards. I have been using mdadm for a long time and would like to stay with it. I am having trouble finding an eight port PCI-express card that does not have all the fancy HW RAID which jacks up the cost. I am now considering using a MB with eight SATA II slots onboard. GIGABYTE GA-M59SLI-S5 Socket AM2 NVIDIA nForce 590 SLI MCP ATX. What are other users of mdadm using with the PCI-express cards, most cost effective solution? - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
