# Data Center Establishment to Run the IT System in Power Utilities Utkarsh Seetha, Rajesh Kumar Rolen & Hitesh Babu Sharma Objective -In this research we will focus the details of the IT System and business process requirements of IT Package need to be installed at Data Centers. This research details the project requirements, which are to be met by the applications and interfaces required within Data Center between different hardware and software systems. The objective of this research includes the design and development of Data Center architecture, hardware availability, proper installation and commissioning of all related networking equipments, storage devices and high end servers as per the current international standards. Keyword : LAN, WAN, MAN, IPS, Switch, VLAN, DC, DR, ACL, SCR, SCC, SaaS, DTMF, SAN. I. # RESEARCH SCOPE FOR DATA CENTRE he data centre project scope shall include the deliverables as mentioned in the document. The brief descriptions of the project scope have been described below in this document. HCL Scope as per the requirements given in the tender document as follows: ? Data Cabling ? Computing Setup with DR Solution ? WAN Connectivity II. # OVERALL SOLUTION DESCRIPTION The overall solution describes the required hardware need to be installed to run the applications/modules for the purpose of the Subdivision Automation of State Electricity Departments in respect to the business functionality. This solution covers the functionality as mentioned and required in the Document as this is an advanced engineered office management tool. It is developed to manage all types of useful databases, analyzes them by applying standard concepts and implement them in a manner consistent with its purpose or design the logic of electrical engineering and subdivision level management in a modernize way. After a deep study of RAPDRP requirements and the difficulties of DISCOMs, our research has suggested the solution with additional amenities. DISCOMs related business functionality would be customized in the product on the base of the Document. Author : Restructured Power Development and Reforms Programme, Rajasthan. The Data Center solution has the capability to integrate with other Business Process Applications as per the requirement captured in system study and suggested by Document. The integration architecture of Data Center solution is based on SOA (Service Oriented Architecture) and due to this it is easily mapped with the integration middleware for exposing the business functionality to external systems as well as to consuming the business functionality of external systems and other future needs which will be fulfilled by the installed hardware, networking equipments and storage devices for coming decades. # Features: ? Flawless Integration of Functions and Processes ? Increase Operation Efficiency # BASIC HARDWARE DESIGN CONSIDERATIONS In this research we will study the Basic Design Principles for the data centre and disaster recovery solution for APDRP which has been arrived at in conformance with the RFP Guidelines, Industry Best Practices, Critical Nature of the Centralized application and our experience in handling such large data centre and Multi-location projects. We have considered the following key design considerations for architecting the Data centre - ? Scalability ? Availability ? Reliability ? Performance ? Security a) Scalability In Utility segment the no of consumers are bound to grow with the increase in population and the usage of IT. Also as the various facilities are extended to new geographical areas the no. of offices / no. of consumers are bound to grow. This necessitates the scalability requirement at the Design level to ensure that there is enough room for growth to meet the future requirements. To meet the Scalability requirements Horizontal scalability, vertical scalability or a combination of both can be used. As per the RFP guidelines we have both horizontal and vertical scalability based on the product set and the application for which it is being used. # b) Availability This is a one of the most important design objective for the datacenter set-up, especially when all the applications are centralized in nature. Highly available Datacenter design ensures that the end users are able to operate and access the applications at all times with desired response time. To meet this objective we have taken care of redundancies at all levels and the choice of technology is to ensure that the applications are made available to the users in any event of failure or disaster. There are two strategies that we have followed in order to meet the above design objectives -? High Availability within the datacenter. ? # d) Performance We also understand that the systems should be designed keeping in view the performance requirement so that the desired response is met at all times. This requires capacity planning at all level to meets the performance availability criteria. Some key aspects which have been taken care in the design to meets the performance requirements are: ? All the Servers have been sized keeping in mind the appropriate concurrency at User Level ? The Servers are being load balanced to ensure that there is no performance choke due to excess load on one server ? The Interconnectivity between servers are on high performance network with Non-Blocking Architecture ? The Bandwidth Capacity planning is done keeping in mind the appropriate user load. # e) Security It's an inevitable fact that security is required at all levels to ensure that the application is available to the users as well as the data is protected from any kind of unauthorized access. In today's environment where the users access the Datacenter from both Intranet as well as Internet it becomes a challenge to ensure that we protect the datacenter from any damage due to different attacks. We have taken care of the following design considerations on the Infrastructure side to ensure end to end security from edge location to the Datacenter - ?![Installing the Antivirus server ?
