Data Center

• It is a facility that contain storage, compute, network, and other IT resources to provide centralized data-processing capabilities.
• Core elements of data center work together to address data-processing requirements
• Application: program provides logic for computing operations
• DBMS: provides a structured way to store data in logical order
• Host or compute: computing platform that runs appliations and database
• network: data path gives communication among various network devices
• storage: that stores data for subsequent use
• Key Characteristics of Data Centre:
• Avilability
• Security
• Scalability
• Performance
• Data integrity: Data integrity refers to mechanisms, such as error correction codes or parity bits, which ensure that data is stored and retrieved exactly as it was received.
• Capacity: when capacity requirement increase, dc must provide additional capacity of resources.
• manageability: A data center should provide easy and integrated management of all its elements. Manageability can be achieved through automation and reduction of human (manual) intervention in common tasks.
• Managing Data Center:
• Data is a collection of raw facts 
• from which conclusions may be drawn and information is the intelligence and knowledge 
• derived from data. Businesses analyze raw data to identify meaningful trends. On the basis of 
• these trends, a company can plan or modify its strategy. 
• Data can be classified as structured and unstructured. Big data refers to data sets whose sizes 
• are beyond the ability of commonly used software tools to capture, store, manage, and 
• process within acceptable time limits.
• Information-centric architecture is commonly deployed in today’s data center. It helps to 
• overcome the challenges of server-centric storage architecture.
• A data center has five core elements such as application, database management system 
• (DBMS), host, network, and storage. 
• The key characteristics of data are availability, security, scalability, performance, data 
• integrity, capacity, and manageability. 
• Virtualization is a technique of abstracting physical resources, such as compute, storage, and 
• network, and making them appear as logical resources. 
• Cloud computing enables individuals or businesses to use IT resources as a service over the 
• network.
