An Introduction to SQL Server Clusters with Diagrams. The options for high availability can get confusing. I was lucky enough to begin working with SQL Server clusters early in my career, but many people have a hard time finding simple information on what a cluster does and the most common gotchas when planning a cluster. Today, I’ll tell you what clusters are, what they’re good for, and why I like to plan out my clusters in a very specific way. I’ll also give an overview of how clustering relates to the Always. On Availability Groups feature in SQL Server 2. SQL Server. What Type of SQL Clustering are we Talking About? There are lots of types of clusters out there. When we cluster SQL Server, we install one or more SQL Server instances into a Windows Failover Cluster. In this post I’m talking specifically about clustering SQL Server 2. Windows Server 2. Key Concept: A Windows Failover Cluster uses shared storage– typically, this shared storage is on a SAN. When a SQL Server instance is installed on the cluster, system and user databases are required to be on the shared storage. That allows the cluster to move the SQL instance to any server (or “node”) in the cluster whenever you request, or if one of the nodes is having a problem. There is only one copy of the data, but the network name and SQL Server service for the instance can be made active from any cluster node. Translation: A failover cluster basically gives you the ability to have all the data for a SQL Server instance installed in something like a share that can be accessed from different servers.It will always have the same instance name, SQL Agent jobs, Linked Servers and Logins wherever you bring it up.You can even make it always use the same IPAddress and port– so no users of the SQL Server have to know where it is at any given time. . Here is a diagram of a SQL Server cluster.The cluster is named SQLCLUSTER0. It has two nodes (servers), which are named SQLCLU0.NODE0. 1 and SQLCLU0. World Poker Championship 2 Cracker . NODE0. 2. People connect to the SQL Server instance at SQLCLU0. A\SQL. The instance has been configured on port 1. Oh no! There’s been a failure in our environment! Here’s what happened. The SQLCLU0. 1NODE0. When this happened, the Windows Failover Cluster service saw that it went offline. It brought up the SQL Server services on SQLCLU0. NODE0. 2. The SQLCLU0. A\SQL instance started up and connected to all the same databases on the shared storage– there’s one copy of the data, and it doesn’t move. As part of the SQL Server startup, any transactions that were in flight and had not committed at the time of the crash were rolled back. While this automatic failover was occurring, users could not connect to the SQLCLU0. A\SQL instance. However, after it came back up they were able to resume operations as normal, and had no idea that a server was still offline. Why You Care About SQL SERVER Clustering. If you’re a business owner, manager, or DBA, you care about clustering because it helps keep your applications online more of the time— when done properly, it makes your database highly available. Here are some ways that clustering makes your life easier: Hardware failures are a nightmare on standalone servers. If a server starts having problems in a failover cluster, you can easily run your SQL Server instance from another node while you resolve the issue. Applying security patches on a standalone server can be very tedious and annoying to the business: the SQL Server is offline while you wait for the server to reboot. By using failover clustering, you can apply patches with only brief downtimes for your application as you move your SQL Server instance to a different node. Failover clusters can also give you an additional tool in your troubleshooting toolkit. Example: if you start seeing high latency when using storage and you’ve ruled out all the immediate candidates, you can fail to another node to try to rule out if it’s a problem with a per- node component like an HBA. Clustering is transparent to the calling application. Lots of things with SQL Server “just work” with clustering, whereas they’re a little harder with other alternatives. With clustering, all of my databases, logins, agent jobs, and everything else that’s in my SQL Server instance fail over and come up together as a single unit— I don’t have to script or configure any of that. I can also cluster my distributed transaction coordinator and fail it over with my instance as well. Gotchas and Notes for Planning a SQL Cluster. Know What Clustering SQL Server Doesn’t Do. The first gotcha is to be aware of what a failover cluster won’t help you with. Clustering won’t improve your performance, unless you’re moving to more powerful servers or faster storage at the same time you implement clustering. If you’ve been on local storage, don’t assume moving to a SAN means a nirvana of performance. Also, clustering doesn’t guarantee that everything involved in your SAN is redundant! If your storage goes offline, your database goes too. Clustering doesn’t save you space or effort for backups or 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. Finally, clusters won’t give you 1.There are periods of downtime when your SQL Server instance is “failing over”, or moving between nodes.Invest Time Determining the Right Naming Convention.You have a lot of names involved in a cluster: a name for the cluster itself, names for each of the servers in the cluster, and names for each SQL instance in the cluster.This can get confusing because you can use any of these names later on when connecting with Remote Desktop– so if you’re not careful, there may be times when you’re not entirely sure what server you’re logged onto! I have two general rules for naming: First, make sure it’s obvious from the name what type of component it is– whether it’s a cluster, physical server, a SQL Server instance, or a Distributed Transaction Coordinator.I also recommend installing BGINFO to display the server name on the desktop for every server in the cluster.Second, name everything so that if you later add further nodes or install another SQL Server instance onto the cluster, the names will be consistent. on this page. Avoid Putting Too Many Nodes in One SQL Cluster. I prefer to have only two or three nodes in a cluster. For example, if I need to cluster five SQL Server instances, I would put them in two failover clusters. This requires a few extra names and IP Addresses overall, but I prefer this for management reasons. When you apply patches or upgrades, you must make sure that each service on your cluster runs on each node successfully after you’ve applied the change. Having a smaller cluster means you don’t need to fail your instance over as many times after a change. Don’t Assume Your Applications Will Reconnect Properly After Failover. Even though your SQL Server instance will come up with the same network name and IPAddress (if not using DHCP), many applications aren’t written to continue gracefully if the database server goes offline briefly. Include application testing with your migration to a failover cluster. Even though the application doesn’t know it’s talking to a cluster (it’s a connection string like any other), it may not reconnect after a failover. I worked with one application where everything worked fine after a failover, except web servers stopped writing their log data to a database because they weren’t designed to retry after a connection failure. The data was written asynchronously and didn’t cause any failures that impacted users, but the issue wasn’t noticed immediately and caused the loss of some trending data.“Active Active” Can Be Useful. My ideal cluster layout to work with is a two node cluster with identical hardware and two SQL Server instances on it. This is commonly called “Active Active” clustering, but that term is technically a no- no. Officially this is called a “Multi- Instance Failover Cluster.” Not quite as catchy, is it? Many people think the ideal situation is to put their most important SQL Server instance on a two node cluster and leave the second node ready, waiting, and idle. So, why do I want a second SQL Server instance? I like to put my critical, heavy hitter database on one of those instances in the cluster.
