Information is the knowledge derived from data. Growth of digital information has resulted in information explosion. We live in an on-command, on-demand world. – We need information when and where required December 1, 2024 Storage Area Network - Module -1 6  Increasing dependency on fast and reliable access to information. Businesses seek to store, protect, optimize, and leverage/control the information. – To gain competitive advantage. – To derive new business opportunity.

December 1, 2024 Storage Area Network - Module -1 10  Big Data Big Data refers to the vast volumes of data that are too large, complex, or rapidly generated for traditional data processing methods to handle effectively. The concept of Big Data is not just about the size of data, but also about the tools, techniques, and methods used to analyze, manage, and extract value from this data. December 1, 2024 Storage Area Network - Module -1 11 December 1, 2024 Storage Area Network - Module -1 12  Big Big Data Data It 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. Includes both structured and unstructured data generated by variety of sources. Big data analysis in real-time requires new techniques and tools that provide: – High performance – Massively Parallel Processing (MPP) data platforms – Advanced analytics Big data analytics provide an opportunity to translate large volumes of data into right decisions.

Data centers are essential for the operations of the internet, cloud computing, and large-scale IT systems, serving as the backbone for virtually all digital services we use today. December 1, 2024 Storage Area Network - Module -1 23  Data Center Data Center It is a facility that contains storage, compute, network, and other IT resources to provide centralized data-processing capabilities. Core Elements of a Data Center; – Application – Database management system (DBMS) – Host or Compute – Network – Storage These core elements work together to address data- processing requirements.

Virtual software mimics the functions of physical hardware to run multiple virtual machines simultaneously on a single physical machine. Virtualization is a technique of abstracting Physical Resources and making them appear as Logical Resources. – For example: partitioning of raw disks. December 1, 2024 Storage Area Network - Module -1 29  Cloud Computing: An Overview Cloud Computing means storing and accessing the data and programs on remote servers, that are hosted on the internet instead of the computer’s hard drive or local server. Cloud computing is also referred to as Internet-based computing, it is a technology, where the resource is provided as a service through the Internet to the User. The data that is stored can be files, images, documents, or any other storable document. December 1, 2024 Storage Area Network - Module -1 30  Cloud Computing: An Overview Enables individuals and organizations to use IT resources as a service over network. Enables self-service requesting and automates request- fulfillment process. – Enables users to scale up or scale down the usage of computing resources quickly. Enables consumption-based metering. – Consumers Pay only for the resources they use. Example: CPU hours used, amount of data transferred, and Gigabytes of data stored December 1, 2024 Storage Area Network - Module -1 31 Some of the Operations that can be performed with Cloud Computing: Storage, Backup, and Recovery of data Delivery of Software on Demand Development of new applications and services Streaming Videos and Audio December 1, 2024 Storage Area Network - Module -1 32 December 1, 2024 Storage Area Network - Module -1 33  Module 1: Summary Key points covered in this module: Data and information Types of data Big data Evolution of storage architecture Core elements of data center Key characteristics of data center Virtualization and cloud computing December 1, 2024 Storage Area Network - Module -1 34
