Roberto, sorry, I only saw the further replies after writing mine. Yes, it's a completely different chip. I think I used it the first time about two years ago. I was given a backup server (as in space to put backups on via samba) to set up - old P4 with a bunch of SATA discs and an LSI card. Performance sucked badly, I thought it was the megaraid driver. Ended up loading Win2k3 server with the newest drivers, and I still got only about 6mb/s sustained. Finally chucked out the LSI and got one of these Adaptec cards - immediately the performance jumped to about 50-60mb/s sustained - which I think is about as fast as that P4 can drive a gigabit NIC. I've used the Adaptec cards ever since and they've served me well Hans -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]
Etch not booting on Adaptec 2420sa
Hello, I just installed the latest etch distro (kernel 2.6.18-3-686) onto a whitebox intel pc running an Adaptec 2420sa raid controller and 4x sata 750gb hd's. The raid is configured as raid5 on three drives with the 4th running hotspare. The etch installer booted fine, saw the raid vol, let me partition it and run a full install. I installed the grub loader into mbr and all looked fine and dandy. The unit boots to the grub menu just fine. When I select the kernel to boot, it gives me the folloeing and just hangs: Booting 'Debian GNU/Linux, kernel 2.6.18-3-686' root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /boot/vmlinuz-2.6.18-3-686 root=/dev/sda1 ro [Linux-bzImage, setup=0x1e00, size=0x131990] initrd /boot/initrd.img-2.6.18-3-686 [Linux-initrd @ 0x1fba9000, 0x44675b bytes] savedefault Any suggestions? I booted to rescue mode and mounted the partition. The kernel images are there and look ok.

It's not hardware RAID. It is software RAID, provided by the BIOS on the card. Now, I am going to take a guess and assume that the 2420sa is also a fake raid. Given that, you are much better off using the kernel's built-in software RAID. Regards, -Roberto [0] http://linux-ata.org/faq-sata-raid.html#ad1210 -- Roberto C.

I had no trouble at all with it. The Adaptec card _is_ hardware RAID. I'm assuming that you correctly created and initialized the volume? Simple question but never hurts to ask. Basically I just followed the quick start guide and it worked, and that's why I have suggestions for you. Just saying that it does work and exactly as it should.
