I'm afraid they have only one with intel RISC on board for hardware raid, which amkes these card rather exensive for me wanting multilple channels, nota higher quality of service. It's like I do not want GB Ethernet, I only wanta single card with 4 Fast Ethernet ports.

Ok, so anybody knows a multichannel adapter? At least 4 channels? Andre? Where do I get one?

Re: Multi-Chanel ATA, was: Re: ATA-4, ATA-5 TCQ status
Hallo, the 3Ware Controllers have up to 8 channels. However I think you can only use one drive per chanel.

Exactly, Jens has seen the ugly beast because I have worked on coding it. I am working to get IBM to change the method of doing this to make it sane, but its not now.

ATA-4, ATA-5 TCQ status
Hi! I would like to ask if the tagged command queueing capability in the decent ATA standards is utilized in the linux IDE driver (2.2 2.2ide patches, or 2.4 maybe...)? Another question, a little bit offtopic is if anybody on this list is able to point me to some pci UltraATA controller card, which has more than 2 channels (more than 4 drives w/o cascade magic) (preferrably 6 or 8 channels)? If the exists one, I do not need no HW RAID or anything like that... I only need a lot of channels, in only one PCI slot. There have been a lot of rant around here, and why I am addressing Andre personally too is that in that debate his stated, that because such cards exist, IDE can fall into line with SCSI in drives possible / PCI slot. Your help is very much appreciated, -- SaPE - Peter, Sasi - mailto:[EMAIL PROTECTED] - http://sape.iq.rulez.org/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
