To reduce installation time, you may consider installing. NET Framework 4 before you run Setup. SQL Server Setup support files. You can install these files by running SqlSupport. Verify that antivirus software is not installed on your WSFC cluster. For more information, see the Microsoft Knowledge Base article, Antivirus software may cause problems with cluster services.

When naming a cluster group for your failover cluster installation, you must not use any of the following characters in the cluster group name:. Verify that you have cleared the system logs in all nodes and viewed the system logs again. Ensure that the logs are free of any error messages before continuing. Before you install or update a SQL Server failover cluster, disable all applications and services that might use SQL Server components during installation, but leave the disk resources online.

Do not set dependencies for disks before Setup. In a Windows Server cluster, the cluster name account computer account of the cluster itself needs to have permissions to create computer objects. For more information, see Configuring Accounts in Active Directory. If the cluster solution includes geographically dispersed cluster nodes, additional items like network latency and shared disk support must be verified.

Verify that the disk where SQL Server will be installed is not compressed or encrypted. Run cluster validation after finding the certified components. SMB File Share is also supported for installing data files. For more information, see Storage Types for Data Files. If you are using SMB file share storage other than Windows File server, please consult the storage vendor for an equivalent setting on the file server side.

A mounted volume, or mount point, allows you to use a single drive letter to refer to many disks or volumes. If you have a drive letter D: that refers to a regular disk or volume, you can connect or "mount" additional disks or volumes as directories under drive letter D: without the additional disks or volumes requiring drive letters of their own.

SQL Server Setup requires that the base drive of a mounted drive has an associated drive letter. For failover cluster installations, this base drive must be a clustered drive. Volume GUIDs are not supported in this release. The base drive, the one with the drive letter, cannot be shared among failover cluster instances.

This is a normal restriction for failover clusters, but is not a restriction on stand-alone, multi-instance servers. Before you install Windows clustering, we need to perform a series of important preparation steps. Once they are complete, then you can install Windows clustering. Here are the steps you must take:. These are a lot of things you must check, but each of these is important. If skipped, any one of these steps could prevent your cluster from installing or working properly.

Now that all of your physical nodes and shared array or SAN is ready, you are now ready to install Windows clustering. In this section, we take a look at the process, from beginning to end.

To begin, you must start the Microsoft Windows Clustering Wizard from one of the nodes. If you are using a SCSI shared array, and for many SAN shared arrays, you will want to make sure that the second physical node of your cluster is turned off when you install cluster services on the first physical node.

Once you have installed cluster services on the first physical node, you can turn on the second physical node, boot it, and then proceed with installing cluster services on the second node. The SQL server will not handle this, as it runs in separate instances, each with its own memory handling.

Is it a setting that needs to configure in SQL that handles the 'insufficient memory' scenario? How do you check if both instance will not consume more than 64GB? Do you manually change the max setting for each instance first to make sure that it won't consume more than 64GB? I tried to search from web on the best practice on how to handle memory allocation for multi-instance failover cluster but no luck. I would like to confirm what is the current situation?
