Hi,
Is there any way or any advantage to building in the twe driver into the
kernel, or is it best to always load it as a module ? I just got a 4port
3ware control and am testing it with a couple of Maxtor 40gig hard drives.
Also, built as a RAID0 stripe,
newgranite# dmesg | grep twe
twe0: <3ware Storage Controller> port 0xe000-0xe00f irq 11 at device 12.0
on pci0
twed0: <3ware RAID unit> on twe0
twed0: 78163MB (160078336 sectors) RAID 255 (unknown)
newgranite#
Should it recognize it as RAID 0 ?
BTW, a quick test gave me the following results on a Celeron with 384M of
RAM with
ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xd400-0xd4ff mem
0xec200000-0xec200fff irq 10 at device 9.0 on pci0
ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs
da0 at ahc0 bus 0 target 0 lun 0
da0: <QUANTUM ATLAS IV 9 WLS 0808> Fixed Direct Access SCSI-3 device
da0: 40.000MB/s transfers (20.000MHz, offset 8, 16bit), Tagged Queueing
Enabled

Thanks for the cool little driver BTW!
