Kernel Limits

The following table summarizes the kernel limits associated with SUSE Linux Enterprise 11. These limits are applicable to all SUSE Linux Enterprise Server and SUSE Linux Enterprise Desktop versions based on Code 11.

SUSE Linux Enterprise 11 Kernel (2.6.27) Limits

	x86 (IA-32)	x86_64 (AMD64 and EM64T)	ia64 (Itanium)	ppc64 (POWER)	s390x (IBM System z)
CPU bits	32	64	64	64	64
max. # logical CPUs	32	512	4096	1024	64
max. RAM (theoretical / certified)	64 GiB / 16 GiB	64 TiB / 512 GiB	1 PiB / 4 TiB	1 PiB / 512 GiB	4 TiB / 256 GiB
max. userspace / kernelspace	3 GiB /1 GiB	128 TiB / 128 TiB	2 EiB / φ	2 TiB / 2 EiB	φ / φ
max. swap space	up to 32 * 64 GB
max. #processes	1048576
max. #threads per process	tested with more than 120000; maximum limit depends on memory and other parameters
max. size per block device	up to 16 TiB	up to 8 EiB

Notes:

φ = insufficient data
Theoretical limits are those which are theoretically possible, based on their design. In other words, systems within these limits should work, at least theoretically. On the other hand, certified limits are those which have been tested by Novell and its partners, and certified to work in real life scenarios.
1024 Bytes = 1 KiB; 1024 KiB = 1 MiB; 1024 MiB = 1 GiB; 1024 GiB = 1 TiB; 1024 TiB = 1 PiB; 1024 PiB = 1 EiB (see also http://physics.nist.gov/cuu/Units/binary.html)
Logical CPUs refer to CPUs that are identified and seen by the Linux kernel. This can be different from the number of physical CPU sockets, which are physical entities typically mounted to a motherboard, or cores, which are also physical entities but usually not visible components of multi-core systems, or virtual CPUs, which are logical CPUs seen within a virtual machine.

File System Support

SUSE® Linux Enterprise was the first enterprise Linux distribution to support journaling filesystems and logical volume managers back in 2000. Today, we support ext3, ReiserFS, XFS, and OCFS2. The current default file system for new SUSE Linux Enterprise 11 installations is ext3, and no longer ReiserFS. OCFS2 is a cluster-aware file system, and is included with our High Availability extension.

Maximum File System Size	16 TiB	16 TiB	8 EiB	16 TiB
Maximum File Size	2 TiB	1 EiB	8 EiB	1 EiB

Notes:

The maximum file sizes above can be larger than the filesystem's actual size when using sparse blocks. Unless a filesystem comes with large file support, the maximum file size on a 32-bit system is 2 GB (2³¹ bytes). Currently all of our standard filesystems (including ext3 and ReiserFS) have large file support, which provides a theoretical maximum file size of 2⁶³ bytes. The numbers in the above table assume that the filesystems are using 4 KiB block sizes. When using different block sizes, the results are different. 4 KiB reflects the most common standard.
1024 Bytes = 1 KiB; 1024 KiB = 1 MiB; 1024 MiB = 1 GiB; 1024 GiB = 1 TiB; 1024 TiB = 1 PiB; 1024 PiB = 1 EiB (see also http://physics.nist.gov/cuu/Units/binary.html)

Accessibility

Novell believes our responsibility is to bring the benefits of technology to people with disabilities. We believe that universal access to computers is important, and we integrate accessibility technologies into our products.

As part of our commitment to accessibility, Novell continues to contribute to open accessibility, in conjunction with Sun and IBM. Our extensive work ranges from infrastructure, to debugging and test, to fast, native OpenOffice.org accessibility.

Recently, Novell extended its technical collaboration with Microsoft to make it easier for all software companies and developers to create and deliver accessible applications across both Windows and Linux platforms. We believe this will improve access to computer technology for people with disabilities even further.

As part of this new collaboration, Novell will develop and deliver an adapter that allows applications written using Microsoft's User Interface Automation (UIA) API to work seamlessly with existing Linux accessibility projects, thus complementing investments made by Sun, IBM and others. To promote interoperability between leading accessibility frameworks in the market, Novell's work will be open sourced. The adapter effectively makes the UIA framework cross-platform, thus enabling UIA to interoperate with the Linux Accessibility Toolkit (ATK), which ships with SUSE Linux Enterprise, vertical applications being migrated from Windows to Linux.
