newbie to SVM....need advice
I have only ever worked with veritas before,so my knowledge of SVM is minimal.
I have a V240 server which is primarily a replacement backup server for the backup server, which will house a heavy read write database application.
This server has 4 internal harddisks (146 GB), I would like the raid config to be 0 +1. So basically the root partition would be included in the stripe. I know this bad practice but this is a test machine.
The server is at OS installation stage ( creating disk partitons) and I would be grateful for any advice how to proceed.
The os will be solaris 10.

It's not bad practice, it's virtually impossible (and it's identically impossible in VxVM as well).
The boot loader has to load the kernel. The kernel is in the root filesystem. The UFS boot loader doesn't understand how to read from a non-contiguous filesystem. So root cannot be striped, concatenated, or raid5 (but it can be mirrored).

You can have a root filesystem mirrored on 2 of the disks, then the remaining space can be a 1+0 stripe/mirror on all 4 disks.
