iostat -E and -e seems to be more applicable to olden days of pure HDDs.
With SAN and RAID , I dun think it's relevant anymore.

Hi Guys,
I've been having some arguments with my colleagues about one thing.

raidfile.conf
RAIDFILE.CONF(5) Box Backup RAIDFILE.CONF(5)
NAME
raidfile.conf - Userland RAID for Box Backup
SYNOPSIS
/etc/box/raidfile.conf
DESCRIPTION
The raidfile.conf is usually generated by raidfile-config(8) but may be manually edited if the store locations move or if more than one
disc set is required.
discX
Specifies a set of discs.
SetNumber
The set number of the RAID disc, referenced by each account.
BlockSize
The block size of the file system (usually 2048). Under BSD with FFS, set this to your file system's fragment size (most likely an
8th of the block size).
Dir0
The first directory in the RAID array.
Dir1
The second directory in the RAID array. If you do not wish to use the built-in RAID functionality, this field should be set to the
same as Dir0. You should not use the built-in RAID if you have a hardware RAID solution or if you're using another type of software
RAID (like md on Linux).
Dir2
The third directory in the RAID array. The same notes that apply to Dir2 also apply to Dir3.
