Leaving aside the performance improvements and re-engineering and architectural changes in Solaris 11, one of the significant and noticeable changes that comes along with Solaris 11 is the introduction of a lot of GNU tools out of the box.

This is my opinion is significant shift in approach from Sun (Oracle) for good reasons allowing users, admins to use more powerful features of the GNU tools that were missing from the default versions.

As we discussed earlier here, you can find the serial number of a Sun Hardware using the utility “sneep”. However, in Sun X86 systems, you can use the pre-installed tool “ipmitool” to find the system serial number. It is not as straight forward as sneep but still is simpl procedure.
