Message-ID: <0f4d9df36e260bf20a669d31e65eebca@quanstro.net> (raw)
yes it would. i'm not too worried about that yet.
i have worked with the dac960 before under linux.
we built a 2TB oracle database using the dac960; the
performance on a 4-way 600Mhz pIII xeon was
exceptional, handily beating 8-way ibm
r50s running oracle on SSAs (serial arrays).
as i understand it, the card is buit around an intel i960
chip that does the arithmatic for raid5.
the good news is that there's a linux driver. the bad news
is similar:
; wc -l /usr/src/linux-2.6.15-gentoo-r1/drivers/block/DAC*
7222 /usr/src/linux-2.6.15-gentoo-r1/drivers/block/DAC960.c
4429 /usr/src/linux-2.6.15-gentoo-r1/drivers/block/DAC960.h
