ServiceLink Manual

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.

# of Users Up to 10
Usage Light (minimal use of remote access, file sharing and other disk-intensive activity. No use of
webmail, virus scanning or VPNs.)
