System Requirements

If you wish to try the system, you will require a PC with a browser, and an internet connection. For full-scale multi-user trials, please contact us.

For most clients, the Caterman service provided over the internet is more than adequate, and does not require the client to support anything more than a PC/browser with internet connection for each user. If a dedicated system is preferred, a server located at a reputable internet server farm or "hotel" is available for £400/$800/€600 per month supporting upto 40 concurrent power users, with additional power users at £10/$20/€15 per month in groups of 10. The number of users is the maximum number of power users that can be logged on to the system at any one time. The standard system can support several thousand users, a user being defined as someone who has a degree of operational control over the system, i.e has a secutiry level greater than zero. Cashless catering account holders and similar are not included, and there may be very many of them logged on at any time limited only by the capacity of the server and its internet connection bandwidth. The number of users is the maximum number of power users that can be logged on to the system at any one time. In a 40-user system at any time there may be up to 40 power users (with security levels greater than zero) logged on plus several hundred non-power users (with security level zero).

The design is four-tier based on a standard browser/PC combination providing the GUI for each user (tier 1), connected over the internet to one of any number of web servers (tier 2). Each web server is supported by one or more of any number of application servers (tier 3) each of which uses one or more data servers (tier 4). Ultimately, the actual data may be segmented by table and spread over several servers each of which might be the largest possible current LINUX machine and each of which may be mirrored.

In-house installations (i.e. where the client owns or leases the computer(s) running CATERMAN) can start with a single powerful PC supporting upto 100 power users.

For an existing in-house configuration supporting 1000 concurrent power users, see Typical 1000-user system

For clients requiring larger user numbers initially, CATERMAN runs on most LINUX machines including IBM xSeries for typically 250 users, IBM pSeries or iSeries for 500 to several thousand users depending on user mix, or IBM zSeries for thousands of users (or a virtual machine on any of these).
