====5.2. RAID1 Support (Disk Mirroring)====
====RAID1 Support (Disk Mirroring)====
With SME Server, 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.

=====5.2.1. Software Mirroring=====
=====Software Mirroring=====
The SME Server comes by default with RAID1 disk mirroring if you install one or two drives. The server is configured to accept one drive and will function properly. You can verify the RAID1 status from the console. --server manager.-- If you later wish to add a second drive, just add it and instruct the server via the console. --server manager.-- to create the mirror. It will take some time to build so do it during scheduled maintenance. They can be either SCSI or IDE drives.

=====5.2.2. Hardware Mirroring=====
=====Hardware Mirroring=====
With hardware mirroring, you use a special RAID disk controller to perform the actual mirroring across multiple disks. As mirroring is performed in hardware, the performance can be significantly faster than software mirroring. Additionally it can simplify configuration because to the operating system the entire RAID disk system looks like one single disk. You should be able to use any supported SCSI hardware RAID controller.

====5.6. Setting Your Administrator Password====
====Setting Your Administrator Password====
As shown in the image below, the first thing you will be asked to do is to set the system password. This is the password you will enter to access the web-based server manager. Depending on how you configure the system, you may also need to enter this password to access the server console. It is extremely important that you choose a good password and keep that password secret.

It is extremely important that you choose a good password and keep that password secret.
{{DrawBoxWarning|content=You can use any ASCII printable characters in the administrator password. As this password gives someone total control over your server, you should choose a password that cannot be guessed easily. A good password should contain mixed upper- and lower-case letters, numbers and punctuation, yet also be easy to remember. An example might be "IwmSMES!" as in "I want my SME Server!" (Please don't use this example as your password!)}}

====Configuring Your Local Network====
=====5.8.1. Selecting Your Local Ethernet Adapter=====
=====Selecting Your Local Ethernet Adapter=====
An ethernet adapter - also called an ethernet card or network interface card (NIC) - is a special piece of hardware that serves as the interface between a computer and the ethernet network. It connects your computer and the ethernet, allowing the computer to communicate with other computers and devices on the network.

It connects your computer and the ethernet, allowing the computer to communicate with other computers and devices on the network.
If you are using a PCI ethernet adapter that appears on our supported list, it is likely that your server will be able to detect your hardware automatically and you will simply be able to choose option 1, "Use xxxx (for chipset yyyy)", where 'xxxx' and 'yyyy' are specific to your hardware. If the software fails to detect it correctly, you can manually select the appropriate driver for your ethernet adapter from a list of drivers or from a list of ethernet adapter models. After the appropriate driver is selected, select "OK" and proceed to the next screen.

=====5.8.2. Configuring Local Network Parameters=====
=====Configuring Local Network Parameters=====
Your SME Server needs information about your local network in order to communicate with the other computers on your network. This includes the IP address and the subnet mask on your server's internal interface. Because your server acts as a gateway and firewall, these will differ from the IP address and subnet mask on the external interface.

=====5.9.1. Option 1: Server and gateway mode=====
=====Option 1: Server and gateway mode=====
In server and gateway mode, your server provides services (such as e-mail, web services, file and print sharing) to your network and also acts as a gateway between your internal network and the outside world. The fact that it serves as a "gateway" means it has separate interfaces with each network, and provides security and routing.

This mode is a variation of option 1 and provides the same functionality with the following differences:
This mode is a variation of option 1 and provides the same functionality with the following differences:
* our web server is not visible to anyone outside of the local network.
* our web server is not visible to anyone outside of the local network.
You would select this mode only if you wish to use the server as a gateway, but do not wish to publish any services to the external Internet.

=====5.9.3. Option 3: Server-only mode=====
=====Option 3: Server-only mode=====
Server-only mode is appropriate if you do not wish to use the gateway capabilities of your server. In this configuration, your server connects only to the local network and does not connect directly to the outside world (although it may connect indirectly through your firewall or another server).

====5.10. Configuring Server and Gateway Mode====
====Configuring Server and Gateway Mode====
If you are configuring your server to operate in server and gateway mode, you must select one of two Internet connection types - a dedicated connection (such as ADSL or cable modem) or a dialup connection (in which case you will be connecting to your ISP via a modem).

====5.11. Server and Gateway Mode - Dedicated====
====Server and Gateway Mode - Dedicated====
How you configure your server's external interface depends on whether you are using a dedicated connection or a dialup connection. Therefore, if you configured your server for "server and gateway mode - dedicated connection" you will be presented with very different configuration screens than if you configured the server for "server and gateway - dialup connection" (as discussed in the next section).

=====5.11.1. Configuring Your External Ethernet Adapter=====
=====Configuring Your External Ethernet Adapter=====
As you did previously with your local ethernet adapter, you need to configure the driver for your external ethernet adapter. As before, the software will attempt to detect the card. If it correctly identifies the card, you can proceed using Option 1, "Keep current driver". If it does not, you will need to manually select the driver.

=====5.11.2. Assigning Your Ethernet Adapters to Network Connection=====
=====Assigning Your Ethernet Adapters to Network Connection=====
To communicate successfully, your server needs to know which ethernet adapter connects it to the internal network and which adapter connects it to the external network/Internet. Your server will make this designation automatically - the first ethernet adapter (in position "eth0") will normally be assigned to the local, internal network and the second ethernet adapter (in position "eth1") will normally be assigned to the external network/Internet. In the event that this assumption is incorrect, this screen allows you to easily swap that designation.

=====Configuring Dynamic DNS=====
If you choose either of the DHCP options or PPPoE, you will be presented with an additional screen where you can choose which dynamic DNS service you wish to use.
If you choose either of the DHCP options or PPPoE, you will be presented with an additional screen where you can choose which dynamic DNS service you wish to use.
The server is pre-configured to operate with four dynamic DNS organizations: yi.org, dyndns.com, dyndns.org, and tzo.com. (You can elect to use a different service, but doing so would require some customization of the server.) Once the service is selected, the subsequent two screens will prompt you to enter your account name and the password for your account. (These two parameters would be given to you by the service. Note that the dynamic DNS service may place restrictions on which domain name you can use for your company.) Please read Appendix B on dynamic DNS for more information about whether a dynamic DNS is right for you.

====5.13. Configuring Your DHCP Server====
====Configuring Your DHCP Server====
You now will be prompted regarding DHCP service. Your SME Server can be configured to provide DHCP service to your internal network. The DHCP server can automatically configure the other computers on your internal network with such parameters as non-routable IP address, subnet mask and gateway IP address. This reduces the risk of error and simplifies the process of configuring your network.

=====5.13.1. Configuring the DHCP Address Range=====
=====Configuring the DHCP Address Range=====
Before the DHCP server is able to assign IP addresses to the computers on your network, you need to tell it what range of IP addresses it can safely distribute. As above, this section is pre-configured with defaults that are appropriate in most situations. If you have fewer than 180 machines on your local network and no reason to prefer one range of IP addresses over another, you can simply accept the defaults for these screens.
