For UFS file systems

For each file system that you create, allocate an additional 30 percent more disk space than you need to enable you to upgrade to future Oracle Solaris versions.

By default, the Oracle Solaris installation methods create only root (/) and /swap. When space is allocated for OS services, the /export directory is also created. If you are upgrading to a major Oracle Solaris release, you might need to reslice your system or allocate double the space that you need at installation time. If you are upgrading to an update, you could prevent having to reslice your system by allocating extra disk space for future upgrades. An Oracle Solaris update release needs approximately 10 percent more disk space than the previous release. You can allocate an additional 30 percent of disk space for each file system to allow space for several Oracle Solaris updates.

The /var file system for UFS file systems

If you intend to use the crash dump feature savecore(1M), allocate double the amount of your physical memory in the /var file system.

Swap

For UFS file systems, the Oracle Solaris installation program allocates a default swap area of 512 MB under the following conditions:

• If you use the installation program's automatic layout of disk slices

• If you avoid manually changing the size of the swap slice

By default, the Oracle Solaris installation programs allocate swap space by placing swap so that it starts at the first available disk cylinder (typically cylinder 0 on SPARC based systems). This placement provides maximum space for the root (/) file system during the default disk layout and enables the growth of the root (/) file system during an upgrade.

If you think you might need to expand the swap area in the future, you can place the swap slice so that it starts at another disk cylinder by using one of the following methods:

• For the Oracle Solaris installation program, you can customize the disk layout in cylinder mode and manually assign the swap slice to the desired location.

• For the JumpStart installation program, you can assign the swap slice in the profile file. For more information about the JumpStart profile file, see Creating a Profile in Oracle Solaris 10 1/13 Installation Guide: JumpStart Installations.

For an overview of swap space, see Chapter 16, Configuring Additional Swap Space (Tasks), in System Administration Guide: Devices and File Systems.

A server that is providing home directory file systems

By default, home directories are usually located in the /export file system.

The Oracle Solaris software group you are installing

A software group is a grouping of software packages. When you are planning disk space, remember that you can add or remove individual software packages from the software group that you select. For information about software groups, see Disk Space Recommendations for Software Groups.

Upgrade

• If you are using Live Upgrade to upgrade an inactive boot environment and want information about disk space planning, see Live Upgrade Disk Space Requirements in Oracle Solaris 10 1/13 Installation Guide: Live Upgrade and Upgrade Planning

• If you are using the Oracle Solaris installation program or JumpStart to plan disk space, see Upgrading With Disk Space Reallocation

• If you have non-global zones installed on a system, see Disk Space Requirements for Non-Global Zones

• If you are upgrading with Live Upgrade for a ZFS root pool, see Chapter 11, Live Upgrade for ZFS (Planning), in Oracle Solaris 10 1/13 Installation Guide: Live Upgrade and Upgrade Planning

Language support

If you plan to install a single language, allocate approximately 0.7 GB of additional disk space for the language. If you plan to install support for all languages, you need to allocate up to approximately 2.5 GB of additional disk space depending on the software group you install.

Printing or mail support

Allocate additional space.

Additional software or third-party software

Allocate additional space.
