Kernel Limits
This table summarizes the various limits which exist in our recent kernels and utilities (if related) for SUSE Linux Enterprise 10 Service Pack 3. This is Novell's award-winning family of Linux operating system products based on a common code base, including SUSE Linux Enterprise Server 10, SUSE Linux Enterprise Desktop 10, SUSE Linux Enterprise Real Time 10 and others.

Remarks:
- The maximum file size above can be larger than the filesystem's actual size due to usage of sparse blocks. It should also be noted that unless a filesystem comes with large file support (LFS), the maximum file size on a 32-bit system is 2 GiB (231 bytes). Currently all of our standard filesystems (including ext3 and ReiserFS) have LFS, which gives a maximum file size of 263 bytes in theory. The numbers given in the above table assume that the filesystems are using 4 KiB block size. When using different block sizes, the results are different, but 4 KiB reflects the most common standard.
- The rationale for the use of theoretical vs. certified in the following tables is as follows: theoretical means that's what should work, at least theoretically, while certified describes something which Novell and our Partners have tested and certified to work on existing machines in real life scenarios. With this explanation, the values for the x86, i.e. 32-bit bigsmp kernels should have been 64 GiB in the first place, but everyone knows that would just be too theoretical as it doesn't really work (and if it did in older kernels, only for very special configurations and workloads).
- In this document: 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)
文件系统支持
早在 2000 年，SUSE Linux Enterprise 就成为支持日志文件系统和逻辑卷管理器的首款企业级 Linux 发行套件。目前，我们拥有运行在一个文件系统内具有超过 8TiB 空间的 XFS 和 ReiserFS 的客户，且 SUSE Linux Enterprise 工程师团队也在对其所有的服务器使用我们的 3 个主要 Linux 日志文件系统。
对于大型文件系统，我们尤其推荐使用 XFS，例如文件伺服（如 Samba、NFS 等）。
