Chapter 6. Installing And Configuring Your SME Server V5 with ServiceLink
Software
6.1. Licensing Terms and Conditions
In installing the SME Server V5 with ServiceLink software, you are agreeing to the open source licensing terms and conditions
associated with it. You can read these terms and conditions in the introduction to this manual under the title Software Licensing
Terms and Conditions.
Warning
The computer on which you install this software will be totally dedicated to being your SME Server V5 with ServiceLink.
The hard drive of this computer will be erased and re-written with the Linux operating system - dramatically enhancing the
reliability of your server over other operating systems. However, this means that while this computer is acting as your
server, you cannot use it for any other purpose.
Note: If you have previously installed and configured a server and are reinstalling the software, please be aware that you must use
the Upgrade option in order to preserve your existing configuration and data. Simply performing a new installation will erase all
previously existing user accounts, user directories, i-bay contents and web site and configuration parameters. If you have not
already done so, you may wish to back up the contents of your server onto one of your desktop computers. You can do so easily by
selecting "Backup or restore" from the server manager, as explained in the chapter on on-going administration of your server.
6.2. RAID1 Support (Disk Mirroring)
With SME Server V5 with ServiceLink, you have the ability to set up disk mirroring, also called RAID Level 1. In disk mirroring,
you basically write all of your data to two separate hard disks installed in your server. One is the mirror of the other. Should the
primary disk experience a hardware failure, the mirror disk will continue operations as if nothing had happened. All of your data will
be protected.
Disk mirroring can be accomplished through either software or hardware .
6.2.1. Software Mirroring
To enable software RAID1 support, you must first have two disks that are either the same size or capable of having partitions of the
same size. They can be either SCSI or IDE drives. They must both be installed in your system prior to installing the SME Server
V5 with ServiceLink software. Software RAID support can only be configured at the time you install the software. If you
choose not to configure RAID support on your server, and later wish to do so, you will need to reinstall the SME Server V5 with
ServiceLink software.
Once you have two disk drives, activating RAID support requires only a very slight change in the software installation process.
Note: SME Server V5 with ServiceLink supports a software implementation of RAID Level 1, known as disk mirroring. It does not
support RAID Level 0 (disk striping), as that does not provide any protection of your data whatsoever. It does not support RAID
