HP Vertica Cluster Architecture

  The physical architecture of Vertica is designed to distribute physical storage and allow parallel query execution on a large collection of computing resources.

 Let's talk about the components that are part of the Vertica cluster. Host Machine with Intel or AMD processor, RAM, hard disk and network interface (TCP / IP IP address and the host name). The host will not share either disk memory space with other hosts. Instance An instance of the HP Vertica is the process in HP Vertica execution and disk storage (catalog and data) on a host. Only one instance of HP Vertica can be run on a host at any time. Node A host configured to run one instance of HP Vertica. It is a database set member. For a database to be able to recover from failure of one we need at least three nodes. It is recommended that you use a minimum of four nodes in building a Vertica cluster. Cluster Refers to the set of hosts (nodes) connected to a database. One set is not part of a definition database and does not have a name. Database A set of nodes that when active, can perform data storage distributed along the SQL statements through administrative, interactive and programmatic interfaces.
