It is not uncommon to have developers and project managers demanding a new instance of SQL Server for every new application or service.

While technologies like virtualization and Cloud have made spinning up new instances a breeze, some age-old techniques inbuilt with SQL Server make it possible to achieve low turn-around times when there is need to provide a new database for a new service or application.

In the article, we shall highlight some considerations we have had the opportunity to experience when using clustering and stacking as a means to consolidate SQL Server databases.

Windows Server Failover Clustering is a very well-known High Availability Solution that has survived many versions of Windows Server and which Microsoft intends to keep investing in and improving.

This state of affairs can be created by a DBA who can design and deploy a large SQL Server cluster capable of supporting most SQL Server databases required by the organization.

There are added advantages to this kind of consolidation such as lower license costs, better governance, and ease of administration.

Consolidating databases on a single SQL Server FCI gives the benefits such as: -- Extract Instance Details -- Includes a Column to Check Whether Instance is Clustered SELECT SERVERPROPERTY('Machine Name') AS [Machine Name] , SERVERPROPERTY('Server Name') AS [Server Name] , SERVERPROPERTY('Instance Name') AS [Instance] , SERVERPROPERTY('Is Clustered') AS [Is Clustered] , SERVERPROPERTY('Computer Name Physical Net BIOS') AS [Computer Name Physical Net BIOS] , SERVERPROPERTY('Edition') AS [Edition] , SERVERPROPERTY('Product Level') AS [Product Level] , SERVERPROPERTY('Product Version') AS [Product Version] , SERVERPROPERTY('Process ID') AS [Process ID] , SERVERPROPERTY('Collation') AS [Collation] , SERVERPROPERTY('Is Full Text Installed') AS [Is Full Text Installed] , SERVERPROPERTY('Is Integrated Security Only') AS [Is Integrated Security Only] , SERVERPROPERTY('Is Hadr Enabled') AS [Is Hadr Enabled] , SERVERPROPERTY('Hadr Manager Status') AS [Hadr Manager Status] , SERVERPROPERTY('Is XTPSupported') AS [Is XTPSupported]; SQL Server supports up to fifty single instances on one server and up to 25 Failover Cluster Instances on a Windows Server Failover Cluster.

Different versions of SQL Server can be stacked on the same environment to provide a robust environment that will support different applications.

With so many drives to deal with you definitely would need to work out a way for both you and the Storage Administrator to identify a disk unique so that maintaining the disks at storage level, for example, would not be much of a hassle.
