RE: [ISSForum] Microsoft SQL Licensing question.



Title: Message
I was told by Tech Support that you only needed 1, for the App server.  This doesn't seem correct to me, especially since there are users in the DB for the Event Collector and Fusion.  However, I don't know much about MSSQL.
 
Is there a way to check the number of licenses used for SQL?

I haven't seen any document from ISS on this matter but i am very interested to know about the licensing of sql server for siteprotector.

Subject: [ISSForum] Microsoft SQL Licensing question.

I am hoping someone from ISS would be able to answer which Microsoft SQL licensing method is required to support SiteProtector with approx. 800 sensors?  I've re-read the licensing FAQ (see below) and am not sure if 'mulitplexing' applies to the number of sensors.  Obviously, getting the processor license eliminates the probelm of CALs, but I'll be installing SQL Enterprise on 3 machines running quad processors and at approx. $20K per processor (12x$20K=$240K), that may be prohibitive for my client.   
 
I'd like to be able to get one Server License (for the Enterprise Database) and 7 Device CALs ( for the 5 Event Collectors, 1 SFM, and 1 Application Server), and be properly licensed.  But again, does 'multiplexing' apply to the machines that the SiteProtector Console is installed on?  If I have 5 remote users using the Console software, do I need a SQL Device CAL for each?  Also, would I need a Device CAL for each sensor?  This would also be cost prohibitive for us (800x$150=$120K).
 
From the 'multiplexing' example below, does a sensor "use its [SQL Server] data, services or functionality"?  The sensor are in contact with the event collectors and the application servers sensor controller service, but I don't see how they would use the SQL data or services, but 'functionality' could be argued.
 
Anyway, thoughts, real-world examples, ISS guidance, would be a great help.

SQL Server is currently available under three licensing options:
 
Processor license. Requires a single license for each CPU in the computer running SQL Server. This license includes unlimited client device access.
 
Server plus device client access license (CAL). Requires a license for the computer running the Microsoft server product, as well as CALs for each client device.
 
Server plus user client access license (CAL). Requires a license for the computer running the Microsoft server product, as well as CALs for each user.
 
SQL SERVER 2000 PROCESSOR LICENSING
Microsoft offers a processor-based licensing model to help alleviate complexity. Processor licenses can be used for any type of application (not limited to Web-based scenarios).
Processor License - A Processor license is required for each processor installed on each server running SQL Server or any of its components (for example, Analysis Services). It includes access for an unlimited number of users or devices to connect from either inside or outside the firewall. Customers do not need to purchase additional Server Licenses or client access licenses (CALs).
Processor licenses are available in both Enterprise and Standard Editions and offer tremendous simplicity.
 
SQL SERVER 2000 SERVER PLUS CAL LICENSING
In addition to Processor licenses, SQL Server 2000 offers separate Server licenses (in both Standard and Enterprise Editions) in conjunction with per device or per user client access licenses (CALs). Server plus CAL licenses are useful to customers using SQL Server in non-Web-based scenarios.
 
Server License - A Server license (for either Standard or Enterprise edition) is required for every server on which that edition of SQL Server software or any of its components (for example, Analysis Services) is installed.
Device CAL - A SQL Server Device CAL is required in order for a device (for example, a PC, workstation, terminal, PDA, mobile phone, and so on) to access or use the services or functionality of either edition of Microsoft SQL Server. The Server plus device CAL model will likely be the more cost-effective choice if there are multiple users per device (for example, in a call center). Please see multiplexing section to ensure every device is licensed properly. The only exception is communication exclusively between SQL Servers.
 
User CAL - A SQL Server User CAL is required in order for a user (employee, customer, partner, and so on) to access or utilize the services or functionality of either edition of Microsoft SQL Server. The Server plus user CAL model will likely be more cost effective if there are multiple devices per user (for example, a user who has a desktop PC, laptop, PDA, and so forth).
 
A CAL is not software; it is a legal document granting a device or user access to server software. A single device CAL grants access to multiple servers for one device (CAL must be same version as latest version of any of the servers). A single user CAL grants access to multiple servers for one user (CAL must be same version as latest version of any of the servers). The following illustrates a scenario requiring two SQL Server licenses and three CALs deployed in the per device mode:
 
MULTIPLEXING: USE OF MIDDLEWARE, TRANSACTION SERVERS, AND MULTI-TIERED ARCHITECTURES
Sometimes organizations develop network scenarios that use various forms of hardware and/or software that reduce the number of devices or users that directly access or utilize the software on a particular server, often called multiplexing or pooling hardware or software. For example, say a client PC is using a server application that calls the Microsoft Transaction Server (MTS) component of Microsoft Windows® 2000 Server on one server, which in turn pulls data from a Microsoft SQL Server database on another server. In this case, the only direct connection to Microsoft SQL Server is coming from the server running MTS. The client PC has a direct connection to the server running MTS, but also has an indirect connection to SQL Server because it is ultimately retrieving and using the SQL Server data through MTS. Use of such multiplexing or pooling hardware and/or software does not reduce the number of CALs required in order to access or utilize SQL Server software. A CAL is required for each distinct device or user to the multiplexing or pooling software or hardware front end. If, in the above example, 50 PCs were connected to the MTS server, 50 SQL Server Device CALs would be required. This is true no matter how many tiers of hardware or software exist between the SQL Server and the client devices that ultimately use its data, services or functionality.
