Note: The following sample configurations are for illustration only and may not be suitable for any specific customer installation. Contact your IBM Business Partner or IBM
Marketing Representative for assistance with your specific configuration requirements.
Internet Server
An Internet server is a server that handles all requests from the Internet (Intranet or Extranet). Usually, this type of server has the same characteristics as a normal file server. The
main difference is that an internet server talks a different language (TCP/IP vs. NETBEUI or IPX/SPX) and often needs to do an extra security check (firewall). In the case of an
Internet server, the server itself talks mostly to just one client, the Internet Service Provider (ISP), instead of many clients like a file server does.
With this is mind, the IBM Netfinity 3500 M20 was selected to provide an affordable price point for the growing Internet server market with up to two-way Pentium III processing
capability, 256 MB of system memory (expandable to 1 GB), and power protection with an APC Smart-UPS.
The network configuration depends on the method that will be used to connect the server to the Internet. Usually fast Ethernet routers are used, but if other methods are used you can
add the appropriate adapter. The configuration includes a tape backup unit for secure backup of critical data in the event of a system or storage failure.
File and Print Server
A small business or departmental server is usually required to perform all typical server functions while servicing up to 100 users in a normal workgroup computing environment,
but doesn’t require the high-end performance and fault-tolerance properties of larger servers.
The sample configuration above consists of an IBM Netfinity 3500 M20 with 256 MB of memory and 54.6 GB of hard disk space. It has enough processor power and memory to run
most current network operating systems comfortably and enough hard disk drive space to store a significant amount of data with additional external storage expansion still available.
Demanding network traffic is effectively handled by the standard 100 Mbps Ethernet connection.
This configuration also includes a tape backup unit, monitor, and a UPS to keep the system protected during power surges and outages.
Application Server
An application server differs from a file and print server in that it has a higher workload, in providing application serving requirements for users. With this in mind, the IBM
Netfinity 3500 M20 was selected to provide an affordable price point for an application server, with two-way Pentium III processing, 384 MB of system memory (expandable to 2
GB), and availability features such as RAID-protected internal storage and power protection with an APC Smart-UPS.
