StarWind Virtual SAN®
Installing and Configuring SQL Server 2019 (TP)
Failover Cluster Instance on Windows Server 2016

Published: October 30, 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 2016 Failover Cluster that will host SQL Server Failover Cluster Instance (FCI).

The Windows Server 2016 hosted storage that will be used for building Windows Server Failover Cluster (WSFC) leverages StarWind Virtual SAN for the implementation of a block-level replication.

This document assumes that:

  • Windows Server 2016 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.

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 Synchronization and iSCSI/StarWind Heartbeat interfaces are in different subnets and connected according to the network diagram above. In this document, 10.1.1.x subnet is used for iSCSI/StarWind Heartbeat traffic, while 10.1.2.x subnet is used for the Synchronization traffic.

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

SQL Server 2019 Windows System Requirements

Make sure that server used for SQL Server 2019 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.

All the requirements for the components can be found at following the link:

https://docs.microsoft.com/en-us/sql/sql-server/install/hardware-and-software-requirements-for-installing-sql-server?view=sql-server-ver15

Software Requirements

  • A minimum of .NET 4.6.1 is required. The SQL Server 2019 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 2016 or 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.

Enabling Multipath Support

4. Open the MPIO Properties manager: Start -> Windows Administrative Tools -> MPIO. Alternatively, run the following PowerShell command:

5. In the Discover Multi-Paths tab, tick the Add support for iSCSI devices checkbox and click Add.
