3 Planning a Storage Solution

Consider what your storage needs are and how you can effectively manage and divide your storage space to best meet your needs. Use the information in this section to help plan your storage deployment for file systems on your SUSE Linux Enterprise Server 11 server.

3.1 Partitioning Devices

For information about using the YaST Expert Partitioner, see Using the YaST Partitioner in the SUSE Linux Enterprise Server 11 Installation and Administration Guide.

3.2 Multipath Support

Linux supports using multiple I/O paths for fault-tolerant connections between the server and its storage devices. Linux multipath support is disabled by default. If you use a multipath solution that is provided by your storage subsystem vendor, you do not need to configure the Linux multipath separately.

3.3 Software RAID Support

Linux supports hardware and software RAID devices. If you use hardware RAID devices, software RAID devices are unnecessary. You can use both hardware and software RAID devices on the same server.

To maximize the performance benefits of software RAID devices, partitions used for the RAID should come from different physical devices. For software RAID 1 devices, the mirrored partitions cannot share any disks in common.

3.4 File System Snapshots

Linux supports file system snapshots.

3.5 Backup and Antivirus Support

3.5.1 Open Source Backup

Open source tools for backing up data on Linux include tar, cpio, and rsync. See the man pages for these tools for more information.

  • PAX: POSIX File System Archiver. It supports cpio and tar, which are the two most common forms of standard archive (backup) files. See the man page for more information.

  • Amanda: The Advanced Maryland Automatic Network Disk Archiver. See www.amanda.org.

3.5.2 Commercial Backup and Antivirus Support

Novell Open Enterprise Server (OES) 2 for Linux is a product that includes SUSE Linux Enterprise Server (SLES) 10. Antivirus and backup software vendors who support OES 2 also support SLES 10. You can visit the vendor Web sites to find out about their scheduled support of SLES 11.

For a current list of possible backup and antivirus software vendors, see Novell Open Enterprise Server Partner Support: Backup and Antivirus Support. This list is updated quarterly.
