Ok, there are performance advantages and disadvantages to RAID5.
First, the advantage: reading is awesome. almost as good as a stripe.
the other advantage: writes in f
Well said.
Thankyou and everyone

Again, I appreciate the responses.

I am dealing with HW RAID. I looked for the "geometry" for my controller,

Thanks thats the exact same question I have.
Does this page,

any validity? The poster makes a good argument, but by seeing Damon's
response it makes no sense to go thru the trouble. I would be willing to try

Ummm, there is NO mirroring in RAID 5. Never has been.

My mistake: not RAID 0, but RAID 1.

Thanks for the responses all.
I want RAID 5 but without mirroring. The data is important but not that
important.
I am planning to use LVM.
If the controller creates a stripe size of 16k, do I need to do anything
special with physical extends (in pvcreate or vgcreate) ?
Do I need to do anything sp

With the RAID array I am planning to use RAID 5 so my data is still
protected. My confusion is going with RAID striping (picking the right
size). Also, Does the filesystem layout need to be specific when I do
striping? If I am using 128k stripes, should I start my filesystem on 129k
and end with ma

Damon,
I haven't even approached the file system level yet. The application is a
basic fileserver which will host our professor's mechanical engineering
images. These images can be anywhere from 20MB to 300MB so I would consider
them "normal files".
I am hoping some hardware people can chime in a
