SV: Does 4.9-RELEASE work with 3Ware RAID card?

[Mike Tancsa]

its slow in RAID5, but thats more RAID5 than anything. This is a 3W-7810

offsite% grep twe /var/run/dmesg.boot
twe0: <3ware Storage Controller> port 0xc000-0xc00f mem 
0xe9000000-0xe97fffff,0xe9800000-0xe980000f irq 15 at device 1.0 on pci1
twe0: 8 ports, Firmware FE7X 1.05.00.056, BIOS BE7X 1.08.00.046
twed0: <Unit 0, TwinStor, Normal> on twe0
twed0: 38165MB (78163312 sectors)
twed1: <Unit 2, RAID5, Normal> on twe0
twed1: 763134MB (1562898560 sectors)
twe0: command interrupt

... However, it can easily handle 10Mb/s streamed at it which is what we 
need it for since its our offsite backup server :)  Our experience in 0,1 
and 10 have been really great.
