Information Storage & Management

Hi All,

Today we will have an overview about Information Storage and Management (ISM) and to know about components of Intelligent Storage System.

Basic Introduction

Information is increasingly important in our daily lives. We have become information dependents of the twenty-first century, living in an on-command, on-demand world that means we need information when and where it is required. We access the Internet every day to perform searches, participate in social networking, send and receive e-mails, share pictures and videos, and scores of other applications.

Here we can learn about the basics of Information, Evolution of Storage technology and Architecture and its core elements.

Data

Data is a collection of raw facts from which conclusions may be drawn. Handwritten letters, a printed book, a family photograph, a movie on video tape, printed and duly signed copies of mortgage papers, a bank’s ledgers, and an account holder’s passbooks are all examples of data.


Today, the same data can be converted into more convenient forms such as an e‑mail message, an e-book, a bitmapped image, or a digital movie. This data can be generated using a computer and stored in strings of 0s and 1s.

Types of data

Data is of two types.

a) Structured data

Structured data is organized in rows and columns in a rigidly defined format.

b) Un-structured data

Data is unstructured if its elements cannot be stored in rows and columns, and is therefore difficult to query and retrieve by business applications. For example, customer contacts may be stored in various forms such as sticky notes, e-mail messages, business cards, or even digital format files such as .doc, .txt, and .pdf. Due its unstructured nature, it is difficult to retrieve using a customer relationship management application.

Information

Data, whether structured or unstructured, does not fulfill any purpose for individuals or businesses unless it is presented in a meaningful form. Information is the intelligence and knowledge derived from data.

Data Center Infrastructure

Organizations maintain data centers to provide centralized data processing capabilities across the enterprise. Data centers store and manage large amounts of mission-critical data. The data center infrastructure includes computers, storage systems, network devices, dedicated power backups, and environmental controls (such as air conditioning and fire suppression).

Core Elements

Five core elements are essential for the basic functionality of a data center:

Application: An application is a computer program that provides the logic for computing operations. Applications, such as an order processing system, can be layered on a database, which in turn uses operating system services to perform read/write operations to storage devices.

Database: More commonly, a database management system (DBMS) provides a structured way to store data in logically organized tables that are interrelated. A DBMS optimizes the storage and retrieval of data.

Server and operating system: A computing platform that runs applications and databases.

Network: A data path that facilitates communication between clients and servers or between servers and storage.

Storage array: A device that stores data persistently for subsequent use.

Key Requirements for Data Center Elements

Availability: All data center elements should be designed to ensure accessibility. The inability of users to access data can have a significant negative impact on a business.

Security: Polices, procedures, and proper integration of the data center core elements that will prevent unauthorized access to information must be established. In addition to the security measures for client access, specific mechanisms must enable servers to access only their allocated resources on storage arrays.

Scalability: Data center operations should be able to allocate additional processing capabilities or storage on demand, without interrupting business operations. Business growth often requires deploying more servers, new applications, and additional databases. The storage solution should be able to grow with the business.

Performance: All the core elements of the data center should be able to provide optimal performance and service all processing requests at high speed. The infrastructure should be able to support performance requirements.

Data integrity: Data integrity refers to mechanisms such as error correction codes or parity bits which ensure that data is written to disk exactly as it was received. Any variation in data during its retrieval implies corruption, which may affect the operations of the organization.

Capacity: Data center operations require adequate resources to store and process large amounts of data efficiently. When capacity requirements increase, the data center must be able to provide additional capacity without interrupting availability, or, at the very least, with minimal disruption. Capacity may be managed by reallocation of existing resources, rather than by adding new resources.

Manageability: A data center should perform all operations and activities in the most efficient manner. Manageability can be achieved through automation and the reduction of human (manual) intervention in common tasks.

Information Life cycle 

The information lifecycle is the “change in the value of information” over time. When data is first created, it often has the highest value and is used frequently. As data ages, it is accessed less frequently and is of less value to the organization. Understanding the information lifecycle helps to deploy appropriate storage infrastructure, according to the changing value of information.
