In a clustered server environment, each server in a cluster is called a node. However, each node has its own RAM, hard drive, operating system, and CPU resources to command. They are responsible for managing and owning their components, which means that work can easily be transferred to ano...
Server Clustering is a process in which a collection of servers, represented as nodes can communicate in- between to make a set of services that ensure high availability to the clients.
Clustering algorithms are sometimes distinguished as performing hard clustering, where each data point belongs to only a single cluster and has a binary value of being either in or not in a cluster, or performing soft clustering where each data point is given a probability of belonging in each ...
In a server cluster, each server owns and manages its local devices and has a copy of the operating system and the applications or services that the cluster is managing. Devices common to the cluster, such as disks in common disk arrays and the connection media for accessing those disks, ...
SQL Server Always On is a high-availability and disaster recovery product for Microsoft SQL server that takes advantage of WSFC. SQL Server Always On has two configurations that can be used separately or in tandem. Failover Cluster Instance (FCI) is a SQL Server instance that is installed acro...
A pod or a cluster is simply a set of computers linked by high-speed networks into a single unit. Computer architects must have reached, at least unconsciously, for terms rooted in nature. Pea pods and dolphin superpods, like today’s computer clusters, show the power of many individuals ...
Clusterings or sets of clusters are often distinguished as either hard clustering where each object belongs to a cluster or not, or soft clustering where each object belongs to each cluster to some degree. This is all apart from so-called server clustering, which generally refers to a group ...
This kind of machine learning is considered unsupervised because it doesn't make use of previously known values (called labels) to train a model. In a clustering model, you can think of the label as the cluster to which the observation is assigned, based purely on its features....
In a SQL Server failover cluster, data needs to be on a shared storage. The cluster can move the SQL Server instance if one node is having a problem because all the data is shared. This solution can guarantee higher up-time and redundancy. Because there is only one storage space, regula...
