What is clustering in SQL Server?

SQL Server clustering is the term used to describe a collection of two or more physical servers (nodes), connected via a LAN, each of which host a SQL server instance and have the same access to shared storage. When the primary server is fixed, you can quickly revert operations back.

How does failover cluster work?

A failover cluster is a group of independent computers that work together to increase the availability and scalability of clustered roles (formerly called clustered applications and services). If one or more of the cluster nodes fail, other nodes begin to provide service (a process known as failover).

What is Failover Clustering in SQL Server?

SQL Server failover clusters are made of group of servers that run cluster enabled applications in a special way to minimize downtime. A failover is a process that happens if one node crashes, or becomes unavailable and the other one takes over and restarts the application automatically without human intervention.

What is window clustering?

Windows clustering is a strategy that uses Microsoft Windows and the synergy of independent multiple computers linked as a unified resource – often through a local area network (LAN). Clustering is more cost-effective than a single computer and provides improved system availability, scalability and reliability.

What is Hyper-V clustering?

What is Hyper-V failover cluster? Failover cluster is a set of several similar Hyper-V servers (called nodes), which can be specifically configured to work together, so that one node can take the load (VMs, services, processes) if another one goes down or if there is a disaster.

Does SQL standard support clustering?

SQL Standard Edition SQL Server Standard Edition will provide most functionality that administrators will want. This includes the most common type of mirroring, and clustering up to two cluster nodes.

What are clustering methods?

Clustering methods are used to identify groups of similar objects in a multivariate data sets collected from fields such as marketing, bio-medical and geo-spatial. They are different types of clustering methods, including: Partitioning methods. Hierarchical clustering.

Does SQL Server 2008 Failover Clustering support cross-subnet failover?

I mentioned “cross-subnet failover” as a great new feature of Windows Server 2008 Failover Clustering, and it is a great new feature. However, SQL Server has not yet embraced this functionality, which means you will still be required to span your subnet across sites in a SQL Server multi-site cluster.

What is the name of SQL Server Cluster?

The cluster is named SQLCLUSTER01. It has two nodes (servers), which are named SQLCLU01NODE01 and SQLCLU01NODE02. People connect to the SQL Server instance at SQLCLU01A\\SQL. The instance has been configured on port 1433.

Does clustering help or hurt SQL server maintenance?

You still need to do all of your maintenance as normal. Clustering also won’t help you scale out your reads. While a SQL Server instance can run on any node in the cluster, the instance is only started on one node at a time. That storage can’t be read by anyone else on the cluster.

Is it possible to run multiple SQL Server instances in cluster?

A: Yes, but it requires some fancy setup. Most SQL Server clusters are installed in the same subnet in a single datacenter and are suitable for high availability. If you want to look into multi-site clustering, “geo-clustering” became available with SQL Server 2008, and is being enhanced in SQL Server 2012.
