Is SQL always on a cluster?
SQL Server Always On is a flexible design solution to provide high availability (HA) and disaster recovery (DR). It is built upon the Windows Failover Cluster, but we do not require the shared storage between the failover cluster nodes. All the participating nodes should be part of the failover cluster.
How do you set a work schedule in SQL?

What is a quorum server?
The cluster configuration database, also called the quorum, tells the cluster which physical server(s) should be active at any given time. Although clusters comprise multiple servers, users or other computers see any given cluster as a single virtual server. The physical servers themselves are called cluster nodes.
Do you need failover cluster for always on availability groups?
Deploying Always On availability groups requires a Windows Server Failover Cluster (WSFC). To be enabled for Always On availability groups, an instance of SQL Server must reside on a WSFC node, and the WSFC and node must be online. Furthermore, each availability replica of a given availability group must reside on a different node of the same WSFC.
When to use SQL Server Agent for Aoha cluster?
When scheduling jobs using SQL Server Agent for AOHA cluster, does one use a Master-Target config as you would as if the servers were separate? Or is there a better way to distribute the jobs to all of the servers so that they can be picked up by one of the replicas in case the primary server fails?
Are there always on availability groups and SQL Server jobs?
There is a very good series by Michael K. Campbell called “ Always On Availability Groups and SQL Server Jobs” . In this article, I will be focusing on one of the practical solutions for management of internal SQL Server jobs in Always On Availability Groups scenarios.
Do you need shared storage for SQL server failover cluster?
However, if you use a SQL Server failover cluster instance (FCI) to host one or more availability replicas, each of those FCIs will require shared storage as per standard SQL Server failover cluster instance installation.
