Yes, the 7000-2, but it uses 2 IDE channels. 3ware only talks to IDE masters. i.e. The 4 drive card uses 4 IDE channels and 4 separate cables, one per drive. I have not yet tried the 8 and 12 port cards, but I assume they are the same. I want to build up a 1 TB machine for testing soon, so I need to buy a 8-port card. Not sure that I will ever need a 12 port. >> Now all I need to find is a source of 3ware IDE cards in New Zealand; >> I haven't found any retail sources so far, and the one distributor I >> found mentioned doesn't even have a website in New Zealand (it redirects >> to a flash-only overseas website). I don't know how many you need, but I buy them from Bell Micro in OEM packs (no cables, no manuals, no software). They come 10 to a box for slightly less than $1000 US. $130 US is for a retail package. You can download the manuals and software, and we did not use their cables anyway. Maybe Bell Micro ships to New Zealand? >> Ewen Greg -- Greg Freemyer _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
