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. To make it even better, they replace the UNIX default versions.
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.

There has been more than one instance when the Sun ILOM was not responsive to commands or were throwing errors. For instance, when you try to run the following command to reset the ILOM

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.

Installing Perl modules in Sun Solaris is not as straight forward but is not very difficult as well.  Perl module installations in Sun Solaris needs GNU Make rather than the default make tool installed. And, requires using perlgcc to build the Makefile.PL than the default perl binary.

In the past we have to mess around with the NDD commands and stats tools like kstat to find the network link status, speed, duplex information in Sun Solaris. With Solaris 10, this has become much easier with the dladm utility.

dladm is the admin utility for Data-Link Interface which helps to display informarthe like Link Status (UP/DOWN), Speed, Duplex, MTU, VLAN Tagged and crucially statistics of network traffic on each of the interfaces historically as well as in real time. dladm can also configure and admin Link Aggregation on multiple NICs which we will not focus here.

sneep (Serial Number in EEPROM) is a cool utility for Solaris that can retreive the Chasis Serial Number (CSN) or the Product Serial Number (PSN). This comes real handy when taking inventory or when having to work with Sun Support. sneep can also store useful information like system Assett Tag or Location into the EEPROM which can be retreived later on.
