Installing and Configuring SQL Server 2012
Failover Cluster Instance on Windows Server 2012

Published: October 15, 2018

 INTRODUCTION

This guide is intended for experienced Windows system administrators, IT professionals, and the SQL Server database administrators who would like to install and configure a 2-node Windows Server 2012 Failover Cluster that will host SQL Server 2012 Failover Cluster Instance (FCI).

The Windows Server 2012 hosted storage that will be used for building Windows Server Failover Cluster leverages StarWind Virtual SAN for the implementation of a block-level replication.

This document assumes that:

  • Windows Server 2012 is installed on each server that would be joined to the cluster and to the Active Directory (AD) domain.
  • The disks (LUNs) are exposed to the servers that should be clustered and are configured according to the StarWind Virtual SAN High Availability Best Practices documentation.
  • The disk witness will be used as a quorum model.

A full set of up-to-date technical documentation can always be found here, or by pressing the Help button in StarWind Management Console.

For any technical inquiries please visit our online community, Frequently Asked Questions page, or use the support form to contact our technical support department.

Solution Diagram

The diagram below illustrates the network and storage configuration of the solution described in this guide.

NOTE: Additional network connections may be necessary, depending on the cluster setup and application requirements. For any technical help in regards to configuring additional networks, please, do not hesitate to contact the StarWind Support Department via online community forum, or via support form (depending on the support plan).

1.Make sure to have a domain controller and the servers added to the domain.

2. Install Failover Clustering and Multipath I/O features on both servers.

3. Configure network interfaces on each node to make sure that the Synchronization and iSCSI/StarWind Heartbeat interfaces are in different subnets and connected according to the network diagram above. In this document, 10.0.0.x subnet is used for the iSCSI/StarWind Heartbeat traffic, while 10.1.1.x subnet is used for the Synchronization traffic.

The procedures mentioned above can be performed by following the instructions below.

SQL Server 2012 Windows System Requirements

Make sure that the server used for SQL Server 2012 deployment satisfies the requirements listed below.

Hardware requirements

Memory: 512 MB minimum for Express, 1 GB for Standard, Developer & Enterprise.

File System: NTFS or ReFS.

Please note that other file systems, such as FAT32, are not supported.

Disk space: 6 GB minimum.

Processor speed: Clockspeed of 2 GHz or more. 1.4 GHz minimum.

Processor cores: 2 cores (Virtual or Physical).

Processor type: 64-bit x64-compatible AMD or Intel CPU only.

Software Requirements:

  • A minimum of .NET 4.6.1 is required. The SQL Server 2012 setup will install the necessary files before the actual installation.
  • The SQL Server setup support files and the native client should be installed first.
  • Client versions of Windows 10 or 8.1 and Windows Server 2012 R2. Windows Server Essentials and Foundation Editions are also supported.
    However, the SQL Server setup requires a GUI and will not work on the Core editions.
  • To install all the components, 8030 MB of the hard disk space is required.
  • The supported storage types are the following:

– Local

– Shared

– Storage Spaces (including S2D)

– SMB (supported with certain limitations)

  • SQL Server has limitations when installing on a domain controller (DC). Failover clustering is not supported on a DC.

The SQL Server Core engine is 64-bit only and does not support the 32-bit editions of Windows 8 or Windows 10. Barring a few 32-bit components (such as Client Tools, Data Quality Client), all other parts require the native 64-bit support.

Cluster Configuration Details

The following prerequisites are used in the configuration:

Active Directory Domain Name: TESTDOMAIN.local

StarWind Virtual SAN Servers IP addresses: 10.0.0.200, 10.0.0.201

Cluster Nodes Names: WS-CLUSTER3, WS-CLUSTER4

Cluster Disks: Q:\, E:\, F:\ & H:\

Windows Server Failover Cluster Name: WINCLUSTER2

Windows Server Failover Cluster IP Address: 172.16.0.211

SQL Server Failover Cluster Name: SQLCLUSTER2

SQL Server Failover Cluster IP Address: 172.16.0.212

SQL Server Service Account: TESTDOMAIN\sqlservice

Connecting to the iSCSI Storage

4. Windows Server 2012 comes with the iSCSI Initiator that enables connection of a Windows host to an external iSCSI storage array, i.e. StarWind Virtual SAN using network adapters. To launch the tool from the Server Manager dashboard, select the iSCSI Initiator in the Tools drop-down menu.

NOTE: These steps should be performed on both servers to act as nodes in the Failover Cluster.

8. Click OK to close the iSCSI Initiator Properties window. Once the targets are defined using the iSCSI Initiator tool, bring the disks online, initialize them, and create new volumes using the Disk Management console.

Initializing and Formatting Disks

9. After configuring the servers to connect to the iSCSI target, proceed with initializing and formatting the disks using the Disk Management console.

10. To launch the tool from the Server Manager dashboard, select Computer Management in the Tools drop-down menu.

NOTE: These steps must be performed on both servers to act as nodes in the Failover Cluster.

21. Repeat the steps above on all disks that need to be configured as part of Windows Server Failover Cluster.

Installing .NET Framework 3.5

SQL Server 2012 requires both Microsoft .NET Framework 3.5.1 and 4.0 as parts of its prerequisite software. The .NET Framework 3.5.1 package is already a part of the Windows Server 2012 installation media, while the .NET Framework 4.0 is included in the SQL Server 2012 installation media. The installation of the .NET Framework 3.5.1 on the Windows Server 2012 machines may lead to issues in case if the Server Manager dashboard is used. For more information about possible issues and workarounds, please navigate to the Microsoft article at the following link.

The Deployment Image Servicing and Management (DISM) Command-Line tool can be used to install Microsoft .NET Framework 3.5.1 on Windows Server 2012.

NOTE: These steps must be performed on both servers that will act as nodes in the failover cluster.

22. To install Microsoft .NET Framework 3.5.1, open the command line and type the following:

Installing Windows Server Failover Clustering Feature

The Windows Server Failover Clustering feature provides high availability and scalability in many server workloads. SQL Server 2012 takes advantage of this feature and its capabilities to support Failover Cluster Instance and the AlwaysOn Availability Group feature. This guide is focused on SQL Server Failover Cluster Instances.

NOTE: These steps must be performed on both servers to act as nodes in the Failover Cluster.

23. To add the Failover Clustering feature:

Open the Server Manager dashboard and select Add roles and features.

Installing SQL Server 2012 Failover Cluster Instance

Initial Cluster Node

Installing SQL Server 2012 Failover Cluster Instance requires appropriate permissions in the Active Directory domain and the local Administrator rights to the machines that will act as nodes in the Failover Cluster. Configuring the appropriate permissions in Active Directory is beyond the scope of this document. For more information, refer to the document Failover Cluster Step-by-Step Guide: Configuring Accounts in Active Directory.

There are two ways to install the SQL Server 2012 Failover Cluster Instance. The first one is to use the integrated failover cluster installation with the Add Node option. The second one is the Advanced/Enterprise Installation option.

The process outlined below describes the first option and the DEFAULT SQL Server instance configuration.

To install SQL Server 2012 Failover Cluster Instance:

39. Run setup.exe from the installation media to launch SQL Server Installation Center. Click on the Installation link on the left-hand side.

40. Click the New SQL Server failover cluster installation to run the SQL Server 2012 Setup Wizard.

70. Reboot both nodes after completing the installation to make sure that there are no pending reboot operations that may be flagged as warnings.

CONCLUSION

The steps described above allow configuring a 2-node Windows Server 2012 Failover Cluster that will host a SQL Server Failover Cluster Instance (FCI). StarWind Virtual SAN was taken as the basis for use in the Windows Server 2012 hosted storage during the implementation of a block-level replication and creating Windows Server Failover Cluster. StarWind VSAN ensures data safety of the entire system and maintains continuous application availability.
