Hey Aj, need guidance . I am building passive physical servers , 4 of them , each node is about 12 cores . This case i might need 24 (2 core packs) of SQL enterprice licenses . SQL licenses on active servers were purchased without SA (SQL 2014 enterprise edition) , do i need to buy licenses for passive farm , active node is 16 core box . How do you think i should play out licensing situation , as for me to minimise license purchase for passive . Can i use 30 or 90 days free run of passive licenses to manage load for a specific month , like black friday load ?.
