1.4. What’s New

For the most complete list of information about changes that have been made in SME Server V5 with ServiceLink, see the release notes that accompany your software.

Chapter 1. Welcome to your SME Server V5 with ServiceLink

1.4.1. ServiceLink

With the release of SME Server V5 with ServiceLink, Mitel Networks Corporation is also introducing ServiceLink, a suite of network-delivered services that extend the functionality of the server. These include:

• 24x7 Alerts and Reporting - Provides round-the-clock monitoring of your SME Server V5 with ServiceLink and your Internet

connection alerting you or your Authorized Partner when there are problems, and compiling monthly performance reports.

• Virus Protection - Automates the downloading and installation of up-to-date virus pattern ﬁles and ensures that all e-mail

messages and attachments are scanned for the latest known threats.

• Guaranteed E-mail - Should your Internet connection fail for any reason, mail destined for your server will be held by our

Network Operations Center (NOC) until such time as it can be delivered successfully.

• DNS Services - Allows users to publish up-to-date DNS records via the Mitel Networks NOC, ensuring that their domain name

remains accessible to the world.

• IPSEC VPN Service - Provides a fast, easy way of linking multiple servers together into a larger network using the secure IPSEC

standard.

Each of the services is described in more detail in the chapter entitled "ServiceLink".

1.4.2. Blades

SME Server V5 with ServiceLink introduces support for blades, a new way of customizing your server. Blades allow you to easily install or remove software modules via the server manager. The section in the Administration chapter on "Blades", describes this feature.

1.4.3. Administration

• New manager panel for viewing log ﬁles - allows you to easily view system log ﬁles and ﬁlter for speciﬁc information.

• Private server and gateway mode - this new server operation mode allows you to use the server’s gateway functionality but not

publish any public services.

• Hostnames and addresses panel - provides more options in the conﬁguration of DNS and host entries.

• Ability to disable user accounts - you can nowdisable, but not delete, a user account to temporarily restrict access to that account.

• server manager interface - the web-based server manager has been refreshed with a cleaner look.

• Secure access to server manager - you can now connect to the server manager using the secure HTTPS protocol.

• New URL for server manager - The URL is now http://www.domainname.xxx/server-manager instead of

http://www.domainname.xxx/e-smith-manager.

• New URL for setting user passwords - The URL is now http://www.domainname.xxx/user-password instead of

http://www.domainname.xxx/e-smith-password.

• Ability to verify desktop backups - you can now check the integrity of a backup to your desktop.

Chapter 2. The role of the SME Server V5

Your SME Server V5 with ServiceLink manages your connection to the Internet by routing Internet data packets to and from your network (which allows all the computers on your network to share a single Internet connection) and by providing security for your network, minimizing the risk of intrusions.

When one of your local computers contacts the Internet, or is contacted by an outside machine on the Internet, the SME Server V5 with ServiceLink not only routes that connection, but seamlessly interposes itself into the communication. This prevents a direct connection from being established between an external computer on the Internet and a computer on your local network thereby signiﬁcantly reducing the risk of intrusion onto your network.

Your server also provides services - including e-mail, web access and a powerful ﬁle sharing and collaboration feature called "i-bays"

- that allow you to communicate better internally and with the rest of the world using the Internet. Throughout this user’s guide, the word gateway is used to mean the computer that acts as the interface between your local, internal

network and the external world.

If you prefer, you can also run your SME Server V5 with ServiceLink in "server-only" mode. In "server-only" mode, your server provides your network with services, but not the routing and security functions associated with the role of "gateway". The server-only mode is typically used for networks already behind a ﬁrewall. In that conﬁguration, the ﬁrewall fulﬁlls the role of gateway, providing routing and network security.

Once installed, your SME Server V5 with ServiceLink can be conﬁgured and managed remotely. Routine administration is handled from your desktop using a web-based interface, so only on rare occasions will you require direct access to the server computer. Once installation is complete, most customers put the server in an out-of-the-way place like a utility closet. If you wish, you can disconnect the keyboard and monitor. (Note that some computers may not operate correctly without an attached keyboard.)

Chapter 2. The role of the SME Server V5

More About Ethernets

Appendix A: Introduction to the Ethernet Local Area Network (LAN), brieﬂy explains ethernets, ethernet components and typical ethernet conﬁguration.

Chapter 3. ServiceLink

With SME Server V5 with ServiceLink, Mitel Networks Corporation has introduced a suite of integrated network services ServiceLink - that extend and enhance the functionality of your server. ServiceLink maximizes the security, performance and reliability of your server through real-time interaction with the Mitel Networks NOC . You can register for ServiceLink by contacting any Mitel Networks Corporation Authorized Partner (please see our website for the name of an Authorized Partner near you) and choosing a subscription plan that meets your needs.

Until you register for ServiceLink, the links to pages in the server manager will take you to panels that are not active. If you would like to enable these services, please visit http://www.e-smith.com/.

Note: If your server is behind an additional ﬁrewall, that ﬁrewall will need to be conﬁgured to allow outbound SSH packets on TCP port 22 in order for ServiceLink to function.

ServiceLink provides the following services:

• 24x7 Alerts and Reporting

This service provides round-the-clock monitoring of your server and your Internet connection. By default, your server will synchronize with our NOC once each hour. (This can be customized by your Mitel Authorized Partner.) If the server fails to check in, an alert is sent to your Authorized Partner and, if desired, your network administrator.

In addition, Mitel Networks Corporation compiles monthly reports summarizing all ServiceLink activity for your Mitel Authorized Partner who in turn can share the information with you. These reports include such details as network performance, e-mail delivery problems and viruses detected. Among other things, this information can help you and your partner assess the reliability and quality of your Internet connection. It can also assist in analyzing the security of your network.

• Virus Protection

This service provides automatic setup and conﬁguration of e-mail virus-scanning services. Your server includes special virus-scanning software. When you subscribe to ServiceLink, your Authorized Partner will activate this special software. Your server will then download the latest virus pattern ﬁles from the Mitel Networks NOC. All e-mail messages and attachments received from that point on will be scanned for viruses. In the event that a virus is found, the message will not be delivered. Instead, the sender, all intended recipients and your Mitel Authorized Partner will be notiﬁed of the virus. The message itself will be quarantined in a special mailbox where the administrator can examine the message and determine what to do with it.

Virus pattern ﬁles contain the information required to accurately identify viruses. As new viruses are detected, anti-virus software manufacturers update their pattern ﬁles. Your server’s virus-scanning service automates the downloading and installation of new virus pattern ﬁles and ensures that the server is always capable of identifying the latest known threats.

Note: The ServiceLink virus protection is limited to 100 users. If you conﬁgure your system for more than 100 users, virus protection will automatically be disabled. The service can, however, be upgraded to support more than 100 users. Please contact your partner for more information.

Chapter 3. ServiceLink

• Guaranteed E-mail

This service provides a backup e-mail service if a server becomes unreachable and cannot receive mail. The most common reason for this is a temporary failure of the Internet connection provided by your ISP. With ServiceLink, mail that cannot be delivered to your server will be stored at the NOC. Simultaneously, notiﬁcations are sent to your Mitel Authorized Partner, who can investigate the cause of the outage.

This service uses what is called an MX secondary. Every domain name on the Internet has a record in the DNS which indicates which system should act as its primary mail exchanger ("MX" for short). When someone sends an e-mail, his or her local mail server will look for the recipient’s MX and send the e-mail to it. If the MX is unreachable due to a system or network outage, the mail may be queued or it may bounce back to the sender.

The guaranteed e-mail service provided to ServiceLink subscribers works by conﬁguring the DNS to use the NOC as a secondary MX. Therefore, if the primary MX is unreachable, the sender’s mail server will send the e-mail to the secondary MX – in this case, the NOC. All e-mail collected in this fashion will be forwarded to your server as it becomes available again.

There is nothing that needs to be done to conﬁgure the guaranteed e-mail service. As soon as the NOC starts publishing your domain through the DNS service, the NOC will be set up to act as an MX secondary and start guaranteeing the delivery of your e-mail.

In addition to storing the e-mail and eventually forwarding it, the Mitel Networks NOC provides notiﬁcation and reporting to your Mitel Authorized Partner. This allows your Partner to identify potential server or network outages at your site and respond in a timely fashion.

• DNS Services

One of the components of a full Internet solution is a domain name. Most businesses using the SME Server V5 with ServiceLink will want to register a domain name representing their business, and will need a DNS host to make this domain name accessible to the world.

For reasons of security and reliability, the server is not conﬁgured to publish DNS records by itself. (Any network server can be conﬁgured to act as a public DNS server, but doing so can create a serious security vulnerability.) A properly administered DNS host needs to be stable and always on the Internet, which is why a Network Operations Center such as that of Mitel Networks Corporation is ideally suited to the task.

The domain name hosting service provided by ServiceLink allows you to publish domain name records via our NOC. In addition to any domain names you may have registered, you will also be able to use the special e-smith.net domain. This provides a low-cost alternative for small businesses or home users who do not wish to pay registration fees for a .com or other domain. Users may register their server with a name such as "mycompany.e-smith.net".

• IPSEC VPNs

As discussed in the section on remote access, your server provides support for client-to-server Virtual Private Networks (VPNs) using PPTP. ServiceLink provides the additional ability to create server-to-server VPNs using the highly secure IPSEC standard. This service allows you to link together servers in different physical locations to make one seamless "virtual" network. Information sent via this network is encrypted to prevent "snooping" by others on the Internet.

To encrypt network trafﬁc between servers, the server uses the IPSEC protocol. This system uses an encryption technique known as public key cryptography. In simple terms, each server connected in a VPN knows the public key of each of the other servers on

Chapter 3. ServiceLink

the network; it uses that key to encrypt data intended for that server. A private key on the receiving server is then used to decrypt the data.

One of the difﬁculties in setting up a VPN is securely exchanging the keys required to set up the VPN. ServiceLink simpliﬁes and automates this process via a trusted central exchange – the Mitel Networks NOC. In addition, ServiceLink also secures and automates the renewal of encryption keys.

When you establish a VPN using ServiceLink, one server is designated to act as the "primary" server - the server whose user accounts will be accessible via the VPN. The other servers in the VPN (known as secondary servers) will function as gateways for the users on their local networks.

Chapter 4. Your Internet Service Provider (ISP)

Your ISP is your connection to the Internet - it routes Internet data packets to and from your server. It also provides other essential services. This section of the user’s guide reviews what ISPs offer and what the implications are in choosing among the various options available to you. While your ISP can also assist you in selecting and arranging the right Internet services for your organization, it’s important to know the general range of services available, since not all ISPs offer all services.

Warning

If you are operating the product in "server-only" mode, you will need to review your gateway/ﬁrewall documentation and perhaps consult with your ISP regarding your conﬁguration. For example, depending on your plans for the server, your ISP may need to publish DNS records associating your mail and/or web servers with your ﬁrewall IP address. Youmay also need to conﬁgure your ﬁrewall for port forwardingof services.

In server-only mode, the single Ethernet connection to the local network is "trusted" as being secure and packet ﬁltering is disabled. For that reason, a server-only server must always be behind a local ﬁrewall. You should not directly connect such a system to the Internet via an Internet Service Provider.

4.1. Dedicated versus dialup connectivity

Connectivity, also referred to as Internet access type, refers to the physical connection between your site and your ISP.How you connect to your ISP affects the speed of your Internet connection, which, in turn, impacts such things as how quickly your web site is displayed to visitors.

Dedicated connectivity refers to a full-time connection to your ISP. Although they are more expensive than the alternative, dedicated connections are generally faster and allow you to use the full range of services on your server. There are several common types of dedicated connectivity. ADSL provides relatively fast data transmission over phone lines. A cable connection links you to your cable company, which provides you with many (though not all) of the same services as a traditional ISP. The speed of transmission over a cable network can vary widely (from quite fast to very slow) based in part on the usage within your neighborhood.

If you have dialup connectivity, your server is not permanently connected to the Internet. Rather, it connects to your ISP over a phone line using a modem. Because your connection to the Internet is not permanent, some of the services on your server cannot be provided to the outside world. For example, having your server host your external company web site would create a problem because whenever your server was not connected to the Internet, the web site would not be available. (However, it could certainly host an intranet web site because the local network would always be connected.)

4.2. The IP address

An IP address is an identifying number assigned to all devices connected to the Internet, and is used in routing information from one device to another. Like your phone number, your IP address enables other people to reach you. In our standard conﬁguration, your ISP only needs to allocate one IP address for your network. It is assigned to your server, which will accept all the Internet data packets intended for your network and distribute them to the appropriate computer - much like an ofﬁce receptionist is able to accept incoming calls and direct them to the appropriate extension.

Chapter 4. Your Internet Service Provider (ISP)

4.2.1. Static versus dynamic IP addressing

A static IP address never changes. It is permanently assigned to your server by your ISP.

Note: Static IP addressing is preferable to dynamic IP addressing because it makes it easier for users on the Internet to connect to your services.

Dynamic IP address assignment means that your IP address is assigned to you only temporarily and may be changed by your ISP. This makes it more difﬁcult to ensure continuity of service to your network. Consider again our telephone number analogy. When your telephone number changes, you are able to place outgoing calls. However, until your new phone number is registered with Directory Services, other people are unable to look up your new number and place calls to you. Similarly, whenever your IP address changes, a record associating your server with its new IP address must be published with the equivalent of Directory Services (known as Domain Name Service or DNS) before incoming trafﬁc can ﬁnd you.

If your IP address is dynamically assigned and you have a dedicated connection to your ISP (for example, with a typical cablemodem), you may ﬁnd it helpful to use a dynamic DNS service. Westrongly recommend you review Appendix B: Dynamic DNS services for more information about this worthwhile option.

4.2.2. Routable versus non-routable IP addresses

If an IP address is analogous to your phone number, then a routable IP address is the equivalent of a full telephone number complete with country code and area code such as +1-613-555-1234. Using the same analogy, a non-routable address is the equivalent of an ofﬁce extension. If your server is assigned a non-routable address, it cannot directly receive incoming Internet connections, which limits the services that it can provide to your site.

4.3. Arranging connectivity with your ISP

If you are going to be using your server in "server and gateway" mode, you will need to arrange for a connection to the Internet. Your ISP will help you connect your site and provide you with services that enable you to take advantage of the Internet (e.g. e-mail delivery). To some extent, the type of connection used determines the services needed. Therefore, we guide you ﬁrst through arranging connectivity and then direct you to the appropriate list of services for each type of connection. The terms used in the following sections are deﬁned at the end of this chapter.

To connect your site to the Internet, you not only need to arrange your physical connection (modem, DSL, etc.), but you also need to ensure that your server can locate the appropriate devices at your ISP’s site. Your ISP will give you this information (e.g. IP addresses for their devices) which must eventually be entered into your server console (a straightforward process covered in a later chapter). Many ISPs use a DHCP server which can directly conﬁgure your server with some or all of these parameters.

4.3.1. Ordering a corporate ADSL or other commercial dedicated connection

Typically, your ISP will arrange for and conﬁgure your external hub and router. Alternatively, you may be required to install that hardware yourself under their direction. If a special phone line is required, the ISP will typically arrange that. It is most typical with

Chapter 4. Your Internet Service Provider (ISP)

corporate service that you receive a routable, static IP address. In fact, usually you will be allocated a block of routable, static IP addresses for your corporation - you will need only one for your server.

Information provided to you by your ISP:

• static IP address (or block of addresses from which you choose one)

• IP address of router ("gateway IP address")

• subnet mask

Order services from: Service List A

4.3.2. Ordering cablemodem or residential ADSL service

Typically, your cable company or ADSL provider will install a conﬁgured cablemodem or ADSL router at your site. If you do not have cable access, your cable company will install it for you. ADSL connects to the ISP via a conventional phone line. If you require an additional phone line, it is typical for you to arrange that yourself. There are three possible conﬁgurations when ordering cablemodem or residential ADSL services.

Chapter 4. Your Internet Service Provider (ISP)

Note: In the tables below, please keep the following information in mind:

1. ISPs often supply the items marked * to your server by DHCP.

2. Some ISPs block outgoing HTTP connections, forcing you to use their proxy server. This interferes in a fewminor wayswith your server (e.g., the test for Internet connectivity will fail erroneously). However, using the ISP’s proxy server will normally work ﬁne.

1. You receive a routable, static IP address Information provided to you by your ISP:

• static IP address

• IP address of cablemodem or ADSL router ("gateway IP address")

• subnet mask

Order services from: Service List A

2. You receive a routable, dynamically assigned IP address and you elect to use a dynamic DNS service (We encourage you to review Appendix B: Dynamic DNS Services for a discussion of dynamic DNS services.)

Information provided to you by your ISP:

• gateway IP address*

• subnet mask*

Information provided by dynamic DNS service:

Chapter 4. Your Internet Service Provider (ISP)

• DNS service account name

• DNS service password

Order services from: Service List B

3. You receive a routable, dynamically assigned IP address and you elect not to use a dynamic DNS service OR your IP address is non-routable.

Information provided to you by your ISP:

• IP address of cablemodem or ADSL router ("gateway IP address")*

• subnet mask*

Order services from: Service List D

4.3.3. Ordering a dialup connection

It is typical for you to purchase and install your own modem for your dialup connection. (Be sure to use a Linux-compatible modem

- WinModems will not work.) Your modem connects to your ISP over a conventional phone line. If you require an additional phone line, it is typical for you to arrange that yourself.

There are two possible conﬁgurations with dialup service:

1. Your ISP is able to meet all of the following three conditions:

• you receive a routable, static IP address

• your ISP will provide a secondary mail server for your domain, which receives e-mail when your server is not connected.

Chapter 4. Your Internet Service Provider (ISP)

• your ISP is able to accept the "ETRN command". (This command is used by the server to retrieve the mail held by the ISP’s

secondary mail server.)

Information provided to you by your ISP:

• static IP address

• dialup access number

• dialup account name

• dialup account password

Order services from: Service List C

2. Your ISP is unable to meet all three of the above conditions Information provided to you by your ISP:

• dialup access number

• dialup account name

• dialup account password

Order services from: Service List D

4.4. Arranging Services From Your ISP

In each section on connectivity, above, we direct you to the appropriate list of services that should be ordered from your ISP.

4.4.1. Service List A

• domain name set up and hosting

• publication of DNS address records for your web server, FTP server and e-mail server

• publication of DNS mail (MX) records

• secondary mail server (optional)

• Internet news server (optional)

Chapter 4. Your Internet Service Provider (ISP)

4.4.2. Service List B

Services to order from ISP:

• secondary mail server (optional)

• Internet news server (optional)

Services From Dynamic DNS Service

• domain name (depending on the service purchased, your dynamic DNS service may restrict what your domain name can be)

• publication of DNS address records for your web server, FTP server and e-mail server

• publication of DNS mail (MX) records

4.4.3. Service List C

• PPP dialup access (with static IP)

• domain name

• publication of DNS address records for your e-mail server*

• publication of DNS mail (MX) records

• secondary mail server (ETRN must be supported)

• Internet news server (optional)

Your web and FTP servers are available to the external world only when your server is connected to the Internet. DNS address records for web and FTP servers only need to be published if it is likely that someone external to your site will need to connect to them for a particular reason.

4.4.4. Service List D

Please read the important notes (below) on the limitations of this conﬁguration.

• PPP dialup access (if you are using dialup connectivity)

• POP mailbox (with generous size limitation)

• domain name - route all mail for domain name to the single POP mailbox

• Internet news server (optional)

Chapter 4. Your Internet Service Provider (ISP)

Some Important Notes on Service List D (Multidrop Mail)

Service list D is applied to conﬁgurations where the publication of DNS records is not practical either because your IP address changes frequently or because it is non-routable. Because there is no published address receiving incoming network connections, this conﬁguration does not allow you to host a web page or FTP site using your SME Server V5 with ServiceLink.

In this case, e-mail is handled using a method called "multidrop", which involves temporarily storing all e-mail messages addressed to your domain in a POP mailbox at your ISP until your server connects and fetches them. Your POP mailbox must be large enough to hold the e-mail for your organization until it is fetched. If your primary ISP cannot supply this, you can use another ISP for your e-mail hosting.

As e-mail messages are delivered into the POP mailbox at your ISP, some of the addressee information is removed. To determine to whom the e-mail message is addressed, your server uses several heuristics. This works very well for normal person-to-person e-mail. However, messages from mailing lists (and other sources where the user’s account name is not present in the headers) cannot be delivered. Any e-mail that cannot be delivered will be returned to the sender. If the e-mail cannot be returned to sender, it will be directed to the system administrator.

Some ISPs add a header to each e-mail message as it enters the POP mailbox to assist in determining the addressee. One common header tag is: "X-Delivered-To". If your ISP does this, make note of the header tag used so that you can conﬁgure your server to look for it (explained in a later section).

Because of the potential problems involved with delivery of e-mail to multidrop mailboxes, we strongly encourage you to consider other means of mail delivery before resorting to using multidrop.

Terms used in ordering connectivity and services

ADSL (or DSL)

ADSL is a type of high-speed Internet access that uses regular phone lines and is available in many metropolitan areas.

Domain Name

This refers to the unique name attached to your organization on the Internet. For example, "tofu-dog.com" or "e-smith.com". If you don’t have a domain name, your ISP can help you select one, ensure it is available, and register it.

DNS (Domain Name Service)

DNS, or Domain Name Service, refers to the software and protocols involved in translating domain names to IP addresses. Your server provides DNS lookup services for your local network, and your ISP typically also provides you with the IP addresses of DNS servers. These servers do not need to be conﬁgured into your server as the DNS server that is provided with your server will correctly resolve all local and Internet names.

DNS: Publication of DNS Address Records

The publication of DNS address information allows other DNS servers to look up your domain information. Your ISP must publish DNS address records associating the name of your web server ("www.domain.xxx"), FTP server ("ftp.domain.xxx") and e-mail server ("mail.domain.xxx") with the IP address of your server.

Chapter 4. Your Internet Service Provider (ISP)

DNS: Publication of DNS Mail (MX) Records

The publication of DNS mail (MX) records is the method used to inform Domain Name Services worldwide that all e-mail to your domain ("yourdomain.xxx") should be delivered to your e-mail server ("mail.yourdomain.xxx").

ETRN

ETRN is a command used for dialup solutions in order to retrieve e-mail temporarily stored at your ISP

Gateway IP Address

A gateway is the device on your network that forwards packets to and from the Internet. The gateway IP address is the IP address for that device.

Internet News Service

If you want access to Internet newsgroups, your ISP will need to provide the IP address of an Internet news server. The ISP will provide direction in conﬁguring your web browser or other newsreading software.

PPP

PPP refers to the "Point-to-Point Protocol" used when a modem connects to the ISP.

PPPoE

"PPP over Ethernet" is a modiﬁed version of PPP that is used over some high-speed ADSL connections to the ISP.

Secondary Mail Server

A secondary mail server receives e-mail for your domain if your server is unavailable, and reattempts delivery later.

Subnet Mask (or netmask)

A subnet mask (or a netmask) has four numeric segments (each between 0 and 255) and looks like an IP address. It enables your computers to deduce what network they are on. Your ISP provides the netmask for the external network between the ISP and your server.

Chapter 5. Hardware Requirements of the SME Server V5 with ServiceLink Host Computer

The hardware requirements of the SME Server V5 with ServiceLink are modest compared with other server software available today. However, because of its critical role in your ofﬁce, selecting an appropriate host computer is important. The hardware requirements of the host computer depend on such things as the number of users on your network, whether you plan to use the proxy server on the server, and the speed of your Internet connection.

Because the SME Server V5 with ServiceLink software relies upon your computer meeting the hardware standards noted in this section, Mitel Networks Corporation cannot support a server installed on hardware that does not meet these standards.

Before you consider the requirements deﬁned below, please be aware of the following notes:

• The server ships with the remote access services disabled by default. Enabling webmail will increase the resource requirements of

your server, in particular the memory requirement. Other remote access services, such as ssh and PPTP, are also processor-intensive. You should consider a fast processor speed if you intend to make signiﬁcant use of these services.

• The server should work with any Pentium, Celeron, AMD or Cyrix processor that can run Red Hat Linux 7.1.

• For a dedicated connection in server and gateway mode, your server requires two ethernet adapters (also called network adapters

or network interface cards). For a dialup connection or server-only mode, one ethernet adapter is needed.

• SCSI (Small Computer Systems Interface) is a system for adding peripherals to a computer which enhances performance,

reliability and scalability. If you are using a SCSI system, you will need a speciﬁc adapter/driver (installed similarly to an ethernet adapter) and will need to purchase SCSI-enabled peripherals. These tend to be more expensive than their non-SCSI counterparts but the tradeoff is often worth it if the system will be under heavy loads.

Note: Our hardware recommendations only apply to servers with up to 500 users. This is not a technical limitation, and the SME Server V5 with ServiceLink can provide services to more than 500 users. In that case, we suggest that you specify a custom system using our Category 4 requirements as the minimum starting point.

5.1. Hardware Requirements for a Category 1 Server

The following information outlines what we consider the minimum system that can give satisfactory performance as a basic ﬁle/print server and network gateway. Note that we do not believe such a system will provide satisfactory performance for features such as webmail, remote access via PPTP and for ServiceLink offerings such as automatic virus protection and IPSEC VPNs.

5.5. Supported Ethernet Adapters

Either one ethernet adapter (in the case of dialup connectivity or server-only mode) or two ethernet adapters (for dedicated connections in server and gateway mode) must be installed on your SME Server V5 with ServiceLink. This section describes which types of ethernet adapter can be used in the computer that will become your server. (There are no restrictions on the ethernet adapters in your other computers.)

Any adapters installed on the server must appear on the following supported list. Note that only PCI adapters are supported. The PCMCIA adapters used in many laptops and the older ISA adapters are not supported.

Note: Because SME Server V5 with ServiceLink is based on Red Hat Linux version 7.1, PCI ethernet adapters that can work with Red Hat 7.1 should also work with SME Server V5 with ServiceLink. You can ﬁnd an up-to-date searchable database at Red Hat’s web site at: http://hardware.redhat.com/redhatready/cgi-bin/us/db-hcl.cgi (Choose Network Device/Controller from the

"Hardware Category" menu.)

5.6. Supported SCSI Adapters

If the computer you plan to use for your server has a SCSI hard disk, your SCSI adapter must be supported by Red Hat Linux 7.1. PLEASE NOTE: Only PCI SCSI adapters are supported by the SME Server V5 with ServiceLink. Furthermore, they must contain a SCSI BIOS so that the PC can boot from the SCSI disk.

Note: As SME Server V5 with ServiceLink is based on Red Hat Linux version 7.1, PCI-based SCSI adapter that can work with Red Hat Linux 7.1 should also work with SME Server V5 with ServiceLink. You can ﬁnd an up-to-date searchable database at Red Hat’s web site at: http://hardware.redhat.com/redhatready/cgi-bin/us/db-hcl.cgi (Choose Storage Device/Controller from

the "Hardware Category" menu.)

Because there are a very large number of SCSI adapters supported, the list below contains the overall categories of supported adapters. If your adapter falls into one of these categories, it is probably supported. Please check with your Mitel Networks Corporation service representative to verify support for your card.

Be aware that your Mitel Networks Corporation service representative may not be able to support you if choose to use a SCSI adapter that is not on our supported hardware list. Please consult your Mitel Networks Corporation service representative for more information.

Note: In the list below the use of an ’x’ symbolizes a wildcard. For example, ’AHA-29xx’ indicates it applies for the ’AHA-2930’ as well as the ’AHA-2940’ and any other models beginning with ’AHA-29’.

5.7. Supported Tape Drives

If you intend to use the tape backup capabilities of the SME Server V5 with ServiceLink, you must have a tape drive that will work with a Linux system.

Webelieve that most SCSI tape drives and many IDE tape driveswill work correctly. Unfortunately, the popular OnStream tape drives do not at the current time work with Red Hat Linux version 7.1, and hence are not supported by your SME Server V5 with ServiceLink.

Wehave tested the following tape drives and know that they work with the SME Server V5 with ServiceLink:

If you do not have one of the supported drives listed above you may want to check with http://hardware.redhat.com/ for information about how well that drive will work with Red Hat Linux 7.1.

Note: If your tape drive is not listed at Red Hat’s site, you can visit http://www.linuxtapecert.org/ to see if your tape drive vendor is participating with that tape drive certiﬁcation effort. Be aware that some of the solutions developedto get certain tape drives to work with Linux may require kernel modiﬁcations and only be attempted by experienced developers.Please consult your Mitel Networks Corporation service representative for more information.
