     BACKGROUND OF THE INVENTION 
     Many different types of problem situations are presented to digital designers, proposal makers and configurators of Enterprise systems using Server Farm networks who have the purpose of laying out, designing and configurating computer server facilities. 
     In order to develop a profile of the particular customer&#39;s situation, involving the type of application requirements he may have, the number of maximum users and normal-situation users utilized in the situation, plus the location and types of sites involved for that particular customer, it is necessary to develop the information and to insert and store this information in a Configuration Database. 
     There have been earlier large and unwieldy attempts in order to develop a customer&#39;s profile which were attempted to be used to eventually determine the best enterprise configuration for the particular customer. However, these often involve considerable guesswork and trial-by-error methods. 
     By using a specific routine which can be laid-out on window screens of a personal computer, it is now possible to present an orderly set of questions and information data developments which will provide a very specific customer profile for meeting the needs of a specific customer or end user. 
     As will be seen in the presently disclosed application, a series of specific steps involving site information, the quality of Servers and Server Farms to be used, the types of applications, the types of users who are involved, and also the types of reliability, availability and redundancy that may be required by the customer, will all be taken into consideration later by a very specific step-by-step algorithmic method which is applicable to a series of window screens on a designer&#39;s personal computer, which will then enable him to develop a specific customer profile which can then be stored in a database designated as the Configuration Session Database. 
     SUMMARY OF THE INVENTION 
     A personal computer is used which has a series of windows onto which may be developed a series of questions and responses which will then enable a user to develop a customer profile for the particular customer which can be stored in a Configuration Session database. 
     The series of windows will lead the person interviewing or communicating with the customer to develop a base of information which will indicate the name, location and the number of users at each locational site. Then, for each site, there is developed a differentiation as to whether this site is a extra-large site or a less-than-large site, in which case different window steps are answered in order to satisfy the types of information that is required. 
     For the smaller, or more manageable sites, there is entered the features and capabilities of the Server Farm, the Server Farm&#39;s primary role and the number of users, followed by information on the types of users which are assigned to each Server Farm. 
     Subsequently, there are windows used to enter information regarding applications, user types and other parameters, such as disk requirements and memory requirements. Subsequently, there is calculated the amount of disk space required for each user-type which uses any particular given application. Later, this information is all collected and stored as a customer profile in a Configuration Session Database.

     GLOSSARY LIST OF RELEVANT ITEMS 
     1. ADJUSTED USER TOTAL (SERVER FARM): The normalized total number of Users that will be supported by the SERVER FARM. Unadjusted Users are grouped into 4 distinct usage-pattern categories, namely (a) Light, (b) Medium, (c) Heavy, and (d) Super Heavy. Calculations are performed on the number of Users in each grouping to determine the normalized number of Users. These normalized numbers are then summed to establish the ADJUSTED USER TOTAL for the entire SERVER FARM. 
     2. APPLICATION DELIVERY SOLUTION CONFIGURATOR: This is the Unisys approved and recognized designation of the present method and system as defined by this invention. This is a Windows application that helps one in choosing the best-developed Application Delivery (Thin Client) server solution that will meet a client&#39;s requirements.

     A new customer configuration interview session is started (B 1 ) to determine a solution for a small customer with one site, for example, containing 2000 users. 
     The marketing/interview personnel would then enter “Customer 2K” at the site name, “Anytown, USA” as the location and 2000 as the number of users (B 2 ) in the Site component of the interview session. Since there is only one site, the decision block “More Sites?” (B 3 ) is answered with “NO”. 
     For the Site entered at step (B 4 ), the site of this example is not considered large (which would be more than 10,000 users) so “NO” is the answer to the decision block “Large Site?” at step (B 5 ). If the answer here was “YES”, then a recommendation for subdividing the site at step (B 6 ) would be requested as described in the co-pending U.S. Ser. No. 09/813,672 entitled “METAFARM SIZER CONFIGURATION METHOD”. 
     In the present illustrative example, one Server Farm is defined as (1) “Manufacturing” with a primary role of “Other” and 800 concurrent users (B 7 ). The features and capabilities are entered for the Farm at step (B 8 ). 
     The “More Server Farms?” decision block at step (B 9 ) is answered with “YES” in this example and a second Server Farm is defined as of Farm (2) “Engineering” having a primary role of an Application Server with 650 concurrent users at step (B 7 ). Features and capabilities required for the Servers are added for the Farm at step (B 8 ). This time, the “More Server Farms?” decision block question (B 9 ) is answered with “No”. The Customer 2K Site is now defined with 2000 total users and the two Server Farms 1 and 2 are defined to serve a total of 1450 users concurrently, i.e., 725 concurrent users for each Server Farm. 
     For the first Server Farm defined and called “Manufacturing” in step (B 0 ), a new User Type is required which provides a “YES” at step B 11  and is defined as “Testers” with the level of “slow” typing speed at step (B 12 ). No more new User Types are required, thus now the New User Type decision block query is “NO” at step B 11 . 
     The Farm example here is assigned two types of users: (i) Developers (a type that exists in the configurator&#39;s pre-defined list of User-Types with insignificant typing speeds) and the new type, (ii) Testers (B 13 ). 
     The decision block question “New Applications?” is answered with “YES” (B 14 ) and a new application is defined here at step (B 15 ) named “IOCooker” using a pre-defined 20 MB of disk space and 2 MB&#39;s of memory. The “IOCooker” application is further defined to make use of a 32-bit environment, text based input and output (I/O) and heavy background processing. Since no more new applications are defined, then the decision block question on “New Application?” is “NO” at step B 14 . The new IOCooker and Internet Explorer 5.0 (an application that exists in the configurator&#39;s pre-defined list of Application Types) are assigned to the Server Farm at step (B 16 ). The Internet Explorer 5.0 has been pre-defined to need 70 MB disk space, 12 MB memory, a 32-bit environment with text based I/O and “light” background processing. 
     For each User Type at step (B 17 ), and each Application type in the Server Farm at step (B 18 ), the User is required to distribute the appropriate portion of the Server Farm&#39;s 800 concurrent Users. Starting with the Developer&#39;s user type, say that 400 users are estimated to be concurrently working with Internet Explorer at step (B 19 ) and they require an additional 200 MB&#39;s of working disk space at step (B 20 ). The question block “Another Application?” at step (B 21 ) is answered with “YES” and the next application, IOCooker, is considered at step (B 18 ) with respect to Developers. No developers are users the of IOCooker Application (B 19 ), therefore, no additional Disk Space is required (B 20 ). The question block “Another Application?” at step (B 21 ) is answered “NO” this time and the Application loop (B 18 -B 21 ) is exited and “Another User Type?” question block is asked at step (B 22 ) and answered “YES” bringing the flow sequence back up to step (B 17 ). 
     The next User Type at step (B 17 ) of Testers (user type ii) is considered with each Application type at step (B 18 ) as assigned to the Server Farm. The remaining 500 concurrent users require distribution among the User/Application pairs. The first Application Type (B 18 ), Internet Explorer, is estimated to be used concurrently by 100 Testers (B 19 ), requiring an additional 25 MB&#39;s of working disk space (B 20 ). The question block “Another Application?” is answered “YES” at step (B 21 ) returning flow sequence to (B 17 ). The 300 Testers are estimated to be using the IOCooker Application concurrently (B 19 ) and require 100 MB additional working disk space (B 20 ). There are no more Applications involved (“NO” at B 21 ) and no more User Types involved (“NO” at B 22 ) left to consider. 
     The decision block question is then asked “Are the numbers of users distributed in Loop B 23 -B 24  equal to the number of concurrent users defined for the Server Farm at B 23 . If the answer is “NO”, then the User is required to redistribute all of the concurrent users among the User Type/Application combination pairs (B 24 ) so that all the concurrent users are covered by a User Type/Application combination. If the answer is “YES” at step B 23 , the distributed number of users is the same as the concurrent users assigned to the Server Farm, (as it is in this example), and the flow sequence continues to (B 25 ) where “Another Server Farm?” is answered with a “YES” (B 25 ) and the loop is now reiterated (at step B 10 ). 
     At this point, the Site Customer  2 K is defined with two Server Farms, (1) Manufacturing (800 users) and (2) Engineering (1500 users). The Manufacturing Server Farm has 400 Developers and 100 Testers using Internet Explorer and 300 Testers using IOCooker, as per Table I. 
     Table I assumes the applications are all in the configurator&#39;s pre-defined Application list with the exception of the IO Cooker which was user-defined and whose attributes were stored when assigned during the Manufacturing (1) Server Farm loop. The Attachmate installation needs 35 MB disk space, plus 8 MB memory, and involves a 32-bit environment, GUI-based input, text-based output and “light” background processing. Access 97 needs 40 MB disk space, 8 MB memory, and involves a 32-bit environment, GUI-based input, Text-based output and “heavy” background processing. This information is relevant when determining a solution. 
     When the information for the Engineering (2) Server Farm is entered, the decision block question “Another Server Farm?” at step (B 25 ) is answered “NO” leading to the “Another Site?” question block (B 26 ) which is also answered “NO”. 
     The interview is now completed (B 27 ) information stored in the Configuration Session Database, 50. The Solution Generation described in co-pending U.S. Ser. No. 09/813,670, can now begin with the following customer profile:
     Site: Customer 2K (200 total users)
       Farm: Manufacturing (800 concurrent users)
           400 Developers use Internet Explorer needing 200 MB disk ea.   100 Testers use Internet Explorer needing 2 MB disk ea   300 Testers use IOCooker needing 1 MB disk ea.   
           Farm: Engineering (650 concurrent users)
           300 Developers use Attachmate Terminal Emulator needing 30 MB disk   200 Developers use Internet Explorer needing 20 MB disk   100 Developers use Access 97 needing 10 MB disk   50 Developers use IOCooker needing 5 MB disk.   
           
       

     Described herein as been a method for developing a specialized customer profile by supplying answers to queries on a Windows screen. Thus, site locations, applications involved, user types, server parameters, Server Farm parameters, disk and memory requirements are recorded into a Configuration Database which will specify the particular profile for the selected customer. 
     While one embodiment of the invention has been described, there may be other variations which can be developed but which are still encompassed by the attached claims.
