How to buy a correct license of MS SQL 2012 or 2014 Standard?

Hi, I'm working on an it project for the Government of Hong Kong. The project will use MS SQL in the database back-end with 100 concurrent users. Please find below issues:

1 do still buy us MS SQL Standard 2012 now, or need to buy MS SQL 2014?

2. in the Site Production, we need to install 2 instances of database. For the execution of the high availability requirements, each database instance will be installed within 2 MS SQL cluster of physical servers (active-passive mode, for failover only) mode. In other words, total 4 physical servers (each server with 6-cores) were used.

A license. review by Core

(2.1) in this case, we need to buy 2 sets of licenses Per Core for the active 2 physical servers only, right?

2.2) because each server is 6 hearts, we buy 3 licenses (pack of 2-cores) for each physical server Active.

including the total we need to buy 6 licenses for 2 active physical servers.

B . Whereas the license server + CAL

(2.1) in this case, we need to buy 2 licenses of server for 2 active physical servers only, right?

2.2) since there are 100 concurrent users, we need to purchase 100 user licenses for each user access to the 2 servers (or 2 instances of database).

3. in the Disaster Recovery (DR) Site, we have 2 physical servers (each being installed with the different database instance) running on the cold standby mode. So, no need to purchase a server license or by Core, right?

4 should we buy Software Assurance (SA)? I guess not that it applies to MS SQL Enterprise Edition only, no?

Please advise on the above scenarios. Thank you very much.

This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)
