Oh, I also placed an order for a Adaptec 2820SA HBA which is a real
RAID controller....
sqorry if I seem silly, but how can any raid controller work without any
software? if not in user space nor kernel space; it must be somewhere
onboard?
The real question is "which functions reside in the module and which
reside in the raid hba".
In earlier times software raid was frowned upon because the server cpu
had
to compute the necessary raid striping, which degraded performance, but
today most cpus are not taxed enough to validate that argument.
I have a dual boot installation Suse/WinXP on a hardware raid5, I dare
you
to try that with software raid. (^-^)
Also, on top of that, I absolutely need 100% transparent hot-spare
functionality, no matter the O/S being running or not.
So, off-board RAID software isn't an option. That means, bye-bye
Highpoint...
Oh yeah.....
Today the Adaptec 2820SA adapter arrived... What a difference!
Everything runs on the controller, and it's MORE than twice as fast than
the Highpoint.
