I feel bad for unleashing yet another raid discussion but bieng pretty
new to all of this I could really use some advice from those who have
been there before.
The goal.... I'm trying to create a storage solution for an
ftp site I'm building somewhere in the range of 250-320GB. The major
goal I'm trying to reach is high storage and low cost. Redundancy is
not a big issue. It would be nice, but I need this pretty cheap.
I read through the archives as well as the supported hardware. Judging
from what I read confidence and support of CCD is generally lacking.
Has this changed recently? Even if it has I think I personally would
be much more confortable with a hardware solution.
In comes the 3ware cards. The HCL says they are supported (even got a
nice man page for it).
The plan.... I think the best way for me to go is 4x 80GB Maxtor
drives running at Raid 0. Seeing as how I don't really care about
redundancy I'll only be using the card to concatenate the disk. Sure
the striping is a bonus.
Is there a better solution for doing this? All I really need is to
concatenate the drives into one logical drive.
Are there any issues with using an additional SCSI card? The 3Ware
cards report the raid array as 1 logical SCSI disk. Maybe I'm not
thinking along the right lines but, would this affect a tape drive
hooked up to a different SCSI card?
Am I just bieng stupid using 4 brand new, just released 80GB maxtors
in a Raid 0 setup?
Has anyone had any issues other than those listed in the man page with
the 3ware cards? Specifically the Escalade 6400
Any other advice or criticisms?
