Hey sbreden! :o) No, I havent tried to tinker with my drives. They have been functioning all the time. I suspect (can not remember) that each SATA slot in the card has a number attached to it? Can anyone confirm this? If I am right, OpenSolaris will say something about "disc 6 is broken" and on the card there is a number 6? Then you can identify the disc?
I thought of exchanging my PCI card with a PCIe card variant instead to reach higher speeds. PCI-X is legacy. The problem with PCIe cards is that soon SSD drives will be common. A ZFS raid with SSD would need maybe PCIe x 16 or so, to reach max band width. The PCIe cards are all PCIe x 4 or something of today. I need a PCIe x 16 card to make it future proof for the SSD discs. Maybe the best bet would be to attach a SSD disc directly to a PCIe slot, to reach max transfer speed? Or wait for SATA 3? I dont know. I want to wait until SSD raids are tested out. Then I will buy an apropriate card capable of SSD raids. Maybe SSD discs should never be used in conjunction with a card, and always connect directly to the SATA port? Until I know more on this, my PCI card will be fine. 150MB/sec is ok for my personal needs. (My ZFS raid is connected to my Desktop PC. I dont have a server that is on 24/7 using power. I want to save power. Save the earth! :o) All my 5 ZFS raid discs are connected to one Molex. That molex has a power switch. So I just turn on the ZFS raid and copy all files I need to my system disc (which is 500GB) and then immediately reboot and turn off the ZFS raid. This way I only have one disc active, which I use as a cache. When my data are ready, I copy them to the ZFS raid and then shut down the power to the ZFS raid discs.) However I have a question. Which speed will I get with this solution. I have 2 SSD discs in a PCI slot => 150MB/sec. Now I add 1 SSD disc into a SATA slot and another SSD disc into another SATA slot. Then I have 5 disc in PCI => 150MB/sec 1 disc in SATA => 300MB/sec (I assume SATA reach 300MB/sec?) 1 disc in SATA => 300MB/sec. I connect all the 7 discs into one ZFS raid. Which speed will I get? Will I get 150 + 300 + 300MB/sec? Or will the PCI slot strangle the SATA ports? Or will the fastest speed "win" and I will only get 300MB/sec? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
