SUSE Linux Enterprise Server 11

System Requirements

Minimum Linux server system requirements for installation

• Local Installation: 512 MB RAM
• Secure Shell (SSH)-based network install, graphical: 512 MB RAM
• Virtual Network Computing (VNC)-based network install using File Transfer Protocol (FTP): 512 MB RAM

Minimum Linux server system requirements for operation

• 512 MB RAM

• 750 MB hard disk space for user data

Recommendations for specific uses

• 512 MB to 4 GB RAM, at least 256 MB per CPU
• 4 GB hard-disk space
• Network interface (Ethernet, wireless or modem)
• For Xen virtual host server – At least 512 MB RAM for each virtual host server
• For Xen virtual machines – At least an additional 256 MB RAM for each virtual machine
• For print servers – A relatively faster processor or additional processors to improve server-based printing
• For web servers – Additional RAM to improve caching, and additional processors to improve Web application performance
• For database servers – Additional RAM to improve caching, and using multiple disks for parallel I/O
• For file servers – Additional memory and disks, or a Redundant Array of Inexpensive Disks (RAID) system to improve I/O throughput

Supported processor platforms

• x86
• x86_64 (AMD64 and Intel EM64T)
• IA64 (Itanium 2)
• IBM POWER
• IBM System z (64-bit)

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 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.
