It's not blindingly fast, but it's at the end of 2 PCI bridges and on a 33MHz 32-bit bus, but it's fine. I've had over 270MB/sec reads out of an 8-way RAID-0 array. (300Mb/sec writes!) although I want raid-6 on all partitions, that drops down to ~130MB/sec read. The problems happen when I plug-in a PCI SATA card (3112 chipset based). I've tried 2 different types of cards and while one is better than the other (causes less or no lock-ups) it's still not perfect. I'm going to try a 4-port card this week. It's solid with only one PCI card in. Assitionally, if I plug a card into PCI slots 3 or 4, then the bios locks up at boot time (Checking NVRAM ... ) Hm. According to the manual, your memory configuration isn't supported - you should be using slots 1 & 2 for each processor to get 128-bit access... I only have 2 x 512MB PC2700 modules in slots 1 & 2 of CPU0. If this box was just going to be a fileserver (NAS sort of thing) then I'd have gone with a single processor, but it's also going to be running some huge CVS and MySQL application (home built version control system) and they specified dual-processors. (The existing setup runs on a dual Xeon PII/700 Dull box which takes up too much rack space and doesn't have enough disks) Gordon - 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
