SR 2.7 includes support for Solaris 10, the new operating system from Sun 
Microsystems. Solaris 10 provides a number of innovative and improved facilities 
over earlier versions. Among these innovative and improved facilities are Dynamic 
Tracing (DTrace), Solaris Containers, Predictive Self-Healing, improved networking 
(new TCP/IP stack), and many others. 

Dynamic Tracing (DTrace) facility can be used by administrators and developers to 
explore the internal operation of the system, track down performance problems, or 
locate the cause of aberrant behavior. It is safe to use on production machines and 
does not require restarting either the system or applications. 

Solaris Containers is a server virtualization and software partitioning methodology 
that can isolate applications and services using flexible, software-defined 
boundaries. Solaris Containers enables you to create many private execution 
environments within a single instance of the Solaris operating system. 

Predictive Self-Healing is an innovative feature that monitors, diagnoses, isolates, 
and recovers from hardware faults and software errors. It works along with Service 
Management Facility (SMF), a feature that replaces the traditional UNIX run-level 
(rc) scripts and enhances the monitoring, starting, stopping, and restarting of both 
operating system and application daemons. 

Solaris 10 Operating System also contains a new and scalable TCP/IP stack that 
increases network throughput and capacity. The TCP/IP stack has been tuned for 10 
Gigabit Ethernet, wireless networking, and hardware offloading technologies.
