  Reporting

  Reporting on a storage infrastructure involves keeping track and gathering information from various components/processes. This information is compiled to generate reports for trend analysis, capacity planning, chargeback, and performance.

  Capacity planning reports contain current and historic information about the utilization of storage, file systems, database tablespace, ports, and so on. Configuration and asset management reports include details about device allocation, local

  or remote replicas, and fabric configuration.

  This report also lists all the equipment, with details, such as their purchase date, lease status, and maintenance records. Chargeback reports contain information about the allocation or utilization of storage infrastructure components by

  various departments or user groups. Performance reports provide details about the performance of various storage infrastructure components.

  Data Center Organizations maintain data centers to provide centralized data-processing capabilities across the enterprise. Data centers house and manage large amounts of data. The data center infrastructure includes hardware components, such as computers, storage systems, network devices, and power backups; and software components, such as applications, operating systems, and management software. It also includes environmental controls, such as air conditioning, fire suppression, and ventilation.

  Large organizations often maintain more than one data center to distribute data processing workloads and provide backup if a disaster occurs.

  Five core elements are essential for the functionality of a data center: Application: A computer program that provides the logic for computing operations Database management system (DBMS): Provides a structured way to store data in logically organized tables that are interrelated Host or compute: A computing platform (hardware, firmware and software) that runs applications and databases Network: A data path that facilitates communication among various networked devices Storage: A device that stores data persistently for subsequent use These core elements are typically viewed and managed as separate entities, but all the elements must work together to address data-processing requirements.
