Hello,
I'm looking for a good raid controller, with good driver support, something I could really rely on !
I have some problems with my 3ware 8006-2 on freebsd 5.3 branch. Actually the box is a p4-3000 hyperthreaded, the 3ware card is running raid1 with 2 maxtor 80go drives. Acually the traffic on the card is less than 2 MB/s.
When the number of transactions/s a value around 70, the controller seems to "lag", the average time par transaction can be more than 10 seconds ! The box also reboot at random intervals giving no messages in the logs.
I don't know if the problem comes from the disks or from the 3ware card. If someone could post iostat values I can expect with other raid cards and/or other disks, it would be great :)
thanks, Julien
