Solaris is an operating system that fits into the UNIX family of operating systems. Solaris 10 supports both AMD and Intel x86-64-bit machines together. Solaris 10 has dynamic tracing (DTrace) and Solaris containers. Solaris 11 is known more as exclusively Solaris 11 Express. In addition to having almost all the features of Solaris 10, Solaris 11 Express introduced several new features. One of these main features is the addition of a new packaging system called IPS (Image Packaging System) for program installation, updates and patching.
What is Solaris 10?
Solaris 10 adds the Java Desktop System, which is based on GNOME. Includes GRUB as a boot loader for x86 systems and iSCSI support. Initial Solaris 10 updates added the ZFS file system, Solaris Trusted Extensions, and Logical Domains. Later updates added Active Directory pools for the Samba server, Solaris Containers for Linux, and improved rcapd (Resource Capping Daemon). Additionally, Solaris 10 includes speed tests such as Speed Test and PowerNow for Intel and AMD processors, respectively. In terms of power management, Intel Nehalem processors are beefed up.
What is Solaris 11?
Solaris 11 uses the Image Packaging System (IPS) to manage mappings and patches. Both packages and patches will be treated as the same items. You need to configure the IPS repository nearby or remotely to pull packages and patches.
- Solaris 11 Express provides a convenient way to install, update, and patch programs in the form of IPS, which was not present in Solaris 10.
- Unlike Solaris 10, important Solaris 11 instructions are in /usr/bin. BSD commands, which were present in Solaris 10, have been deprecated in Solaris 11 Express and their use is also deprecated.
- Compared to solaris 11, Solaris 10 does not maintain ZFS encryption and probably never will.
- The main differences are package management, operating system installation methods, zone enhancement, and network virtualization.
- Solaris 11 Express provides a quick way to install, upgrade, and patch programs in the form of IPS, which was not present in Solaris 10. It is also much easier to upgrade to Solaris 11 from OpenSolaris.
- Compared to solaris 10, Solaris 11 (old OpenSolaris) has improvements in its networking stack, you can do virtual-nics, using dladm.
- Compared to solaris 10, Solaris 11 can break into a switch/router/firewall.
