I was recently asked question about SQL Server 2008 pricing. I have bookmarked official site here which lists the pricing.
Official site: What’s New in SQL Server 2008 R2 Editions
|Editions||Per Processor PricingRetail
||Per Server Plus CAL PricingRetail
|Parallel Data Warehouse||$57,498||Not offered via Server CAL|
|Datacenter||$57,498||Not offered via Server CAL|
|Enterprise||$28,749||$13,969 with 25 CALs|
|Standard||$7,499||$1,849 with 5 CALs|
However, I have bookmarked following site of Brent Ozar SQL Server 2008 R2 Pricing and Feature Changes. I think Brent has answered one very interesting question there that SQL Server R2 is FREE for only who has purchased software assurance.
I really would like to know if your organization is upgrading to SQL Server 2008 R2. Please leave your comment here.
