Recommended Configuration Values Summary
The following table summarizes all used and recommended variables and their values when configuring hosts for Solaris
Operating System.
NOTE: Unless indicated otherwise, use the default parameters values.
NOTE: Solaris OS can use two types of disk drivers to manage disk storage. The driver type depends on the platform
architecture (x86 or SPARC) and the version of Solaris installed on the platform.
All versions of Solaris x86 OS are using SD disk drivers to manage all disk storage.
For SPARC platform versions prior to 11.4, release SSD driver type is used to manage all disk storage.
To simplify configuration and disk storage management, as of SPARC platform version 11.4, both platforms are using SD
driver.
If the SPARC system is upgraded to Solaris 11.4 from one of the earlier versions, the system will continue to use SSD driver.
All new installations of Solaris 11.4 will be configured to use SD driver for disk management.
Make sure that you update the tuning settings in the correct disk driver configuration file.
