The Solaris 2.6 release supports all sun4c and sun4d platforms. Most sun4u and sun4m platforms are also supported, but check with your hardware vendor for exceptions.
Solaris 2.6 installation requires a minimum of 16 Mbytes of RAM. At least 32 Mbytes of RAM is strongly recommended (Solaris Web Start requires 48 Mbytes of RAM). On some platforms, 16 Mbytes of RAM will not support the installation graphical user interface (GUI), which means the character user interface (CUI) must be used to install the Solaris 2.6 release.
The minimum disk space requirements for the Solaris 2.6 release are described in this table.
Contact your hardware manufacturer to determine if a specific system or device is supported by the Solaris 2.6 release.
