Hi, *SM Gurus:

I really need you guys help on this one:
I need to create a disk pool around 450G (50 9G disks)
. My basic layout would be: create 10 logical volume,
each lv spans on 5 disks. When creating the LVs, There
is three policies I can use 1) RANGE of physical
volumes set to minimum, which mean use them
sequetially, 2) RANGE of physical volumes set to MAX,
which means use soft-stripping with stripping block
size=PP size (16Mb) 3) use striping, set the blksize
to 4,8,16,32,56,128k.

What is the efficent way to layout on disk pool setup?
Should I use striping or not? If striping is
prefrered, what should be the striping block size, 4k
,16k or 56k?

What is you guys current setting, if you also have a
huge diskpool?

Thanks a lot
