RAID interleave for Solaris Volume Manager

Hi managers,

I have a basic question regarding -i flag for metainit. What does this
interlace size mean in terms of actual disk writes ?

Suppose I have an application that writes in 64KB chunks. I want Solaris
Volume manager (on solaris 9) to match this: I am trying to dodge multiple
writes per application write

1) For a RAID 0+1 volume composed of 5+5 disks -i 16k will give a __kb
chunk ?
2) For a RAID 5 volume of 10 disks how is this stripe size related to
interlace ?

What should I read to grasp this relationship ? Basically I am trying to
extract as much performance from a A5200 as possible.

Thank you again,
-ansh
