Codename Aurora will be known as Windows Small Business Server 2011 Essentials. Priced at $545, it is slated for release in the first half of 2011. Windows SBS 2011 Essentials is targeted at small businesses that want to deploy their first server. It protects your data, lets you organize and access business information from virtually anywhere, supports business applications, and connects to online services such as Office 365, hosted e-mail, collaboration, and CRM. It can be used by up to 25 users and requires no CALs for user access.
Codename SBS 7 will be known as Windows Small Business Server 2011 Standard. Priced at $1,096, with CALs going for approximately $72, it is slated for release in December 2010 (available through OEMs and System Builders in February 2011). It is aimed at small businesses with up to 75 users that want enterprise-class server technology, automatic daily server backups, and features like e-mail, Internet connectivity, internal websites, remote access, as well as file and printer sharing. Licensing is consistent with previous versions of Windows SBS 2008 Standard, which required a Server License and CALs for each user.
Finally, there will be a server add-on known as Windows Small Business Server 2011 Premium Add-on. Priced at $1,604, with client-access licenses going for approximately $92, it too is slated for release in December 2010 from Microsoft and February 2011 from OEMs and System Builders. The add-on consists of an additional server that provides support for SQL Server-based LOB applications and access to Window Server 2008 R2 technologies. It includes Windows Server 2008 R2 Standard as well as SQL Server 2008 R2 for Small Business, and can be added to both previously mentioned SBS 2011 products. Access to the Windows Server components for the add-on will be covered by the Windows SBS 2011 CAL model, but SQL Server access will require Premium Add-on CALs. Microsoft said it decided to move to an add-on model to give its customers "more flexibility and deployment options providing the ability to purchase additional servers either up front or as needed."
Microsoft has two more Windows Server products on the way. We've known about codename Vail, the second version of Windows Home Server, for a while now, but there's another one: Windows Server codename Breckenridge, according to a Microsoft Connect page titled "Windows Server Solutions Log Collector Privacy Statement" (via ZDNet). Breckenridge will reportedly be a derivative of Windows Home Server Vail optimized to function as a storage server. The release details about these two have yet to be finalized.
