hi,

what are the RAID Levels followed for various File systems ?

thanks

sorry i don't understand your question...
RAID levels have nothing to do with the filessystem, the raid is the device where you can install a filesystem but not in the otherway....
RAIDs [A case for Redundant Arrays of Inexpensive Disks] are standards defined by the Berekley University. defined are RAID 0-5 and compinations like 1+0 or 0+1. use your google to search for the principles behind the diff levels.

what are the RAID Levels(software RAID) using VVM we can implement for various File systems ?

for file systems :

root
/usr
/var
/export/home

as i know VxVM (and SVM/SDS) there is no possibility to use other raidlevels than RAID1 for the root disk, because when you boot your sun your solaris-mini-kernel need the possibility to read the kernel-systemparameters in a plain way.... cannot believe there is a other way to do that...
it's very easy to mirror the root disks with VxVM, when you have installed your VxVM just type vxdiskadm, there is a wrapper for mirroring disks...
