The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION

The present invention relates to optimization of data centers. Particularly the invention provides a method and system for optimizing networks in data centers and transformation of the data centers for consolidation.

BACKGROUND OF THE INVENTION

To support the consumer requirements  organizations across the information technology sector house big and complex IT infrastructure at different locations. These complexes  also known as data centers  comprise a variety of equipments such as plurality of servers  plurality of storages devices  various equipments such as telecommunication  networking  switch and other electronic equipment.

Introduction of new products or services  often flood the businesses with large number of consumers and their queries  making it necessary to refresh the infrastructure to meet the needs. However  the existing economic situation and challenges faced by a chief information officer (CIO) does not permit an organization to invest in refreshing the existing infrastructure.

One of the major challenges faced by a CIO is to run the IT operations both at organizational level and at data centers as a profit center rather than as a cost center as it accounts for 10-20% of total cost of ownership. To meet the challenge the CIO has to find way by which he or she can consolidate multiple data centers to fewer ones  optimize the network infrastructure at the existing data centre  so that the cost of operations can be reduced. However  to dynamically optimize or transform the data centre or IT infrastructure  the CIO has to depend upon network vendors such as Cisco  Juniper to carry out necessary network related modifications.
The patent application US20070299746 by Haley et al. discloses a convergence tool for analyzing an information technology infrastructure that integrates network performance  quality of experience (QoE)  and anticipated financial return parameters  which are interdependent on one another. One aspect of the invention includes a method including a step of identifying an information technology infrastructure configuration having an estimated subscriber load resulting from at least one service provided over the infrastructure. Performance metrics for the infrastructure can be computed based upon the subscriber load. Quality of experience metrics for subscribers receiving the service via the infrastructure can be determined based in part upon the computed performance metrics. Financial metrics can be calculated that are based in part upon an expected subscriber population  which is based in part upon the determined quality of experience metrics. The expected subscriber population can be used to adjust the estimated subscriber load. Haley et al. provides information relating to capacity upgradation of a network or data center by predicting the load and performance of the network and lays not emphasis on system re-architecting of the existing setup.

US20060053094 by Prasad et. al. discloses a method for self-service  automated information technology infrastructure management system that includes receiving minimal information pertaining to an information technology infrastructure from a user at a web portal  automatically gathering additional infrastructure information using the minimal information received from the user  and automatically monitoring the information technology infrastructure by collecting infrastructure data and examining the collected infrastructure data for a deviation from a normal operating condition. The disclosure by Prasad et. al. mainly focuses on analyzing the existing setup of the network infrastructure by performing as a management tool for operation.
The method and system disclosed in US20110022812 application filed by Linden et al. teaches about establishing a cloud bridge between two virtual storage resources and for transmitting data from one first virtual storage resource to the other virtual storage resource. The system disclosed includes a first virtual storage resource or cloud  and a storage delivery management service that executes on a computer and within the first virtual storage resource. The storage delivery management service receives user credentials of a user that identifies a storage adapter. Upon receiving the user credentials  the storage delivery management service invokes the storage adapter which then executes an interface that identifies a second virtual storage resource and includes an interface translation file. The storage delivery management service accesses the second virtual storage resource and establishes a cloud bridge with the second virtual storage resource using information obtained from the second virtual storage resource and information translated by the storage adapter using the interface translation file. Linden et al. provides a cloud bridge between virtual storage devices for performance monitoring and reporting.

US20100042449 by Thomas discloses a method according to an embodiment that comprises accessing one or more parameters based on an IT service request received from an upper-layer IT interface  the parameters formatted according to an upper-layer IT interface construct. Appropriate IT domains are determined  according to at least a portion of the parameters  from a number of IT domains for implementing IT infrastructure for fulfilling the request  the domains each associated with one or more vendor-specific solutions for providing IT infrastructure of a type associated with the domain. Using a common semantic inter-relational data model that includes mappings of constructs for upper-layer IT interfaces to constructs for IT domains  at least a portion of the parameters are translated from the upper-layer IT interface construct into constructs suitable for use by the determined appropriate domains. One or more parameterized instructions operable to cause appropriate vendor-specific implementations of the determined appropriate domains to implement appropriate infrastructure for fulfilling the request are communicated. The system deals with monitoring and reporting of heterogeneous infrastructure.

The US2002069102 application by Vellante et al. discloses a method and system for assessing and quantifying the business value of an information technology application or set of applications  particularly as those application or applications are subjected to a proposed change or variation. The method includes steps wherein a base application value is derived  following which a business experience based coefficient or factor is derived and  by using that coefficient or factor  the base application value is uplifted to provide an actual application value for an application or applications. A potential business value is derived by operating on the actual application value with a value representing the perceived value of an enablement attribute construct corresponding with the noted change to be applied. The ultimately sought net business value is derived for an application by removing the operational cost of the application from the potential business value. As an adjunct to the method the actual application value may be increased by the value of the highest optimized business value of an enablement attribute construct of the application to provide upper bound maximum business value of an application for comparing the relative results of any given analysis.

Peng et al. in “On-Demand Services Composition and Infrastructure Management” describes about several engineering applications that involves distributed software services. Due to the complexity of these applications  an efficient and flexible service composition framework is needed. A reference service composition framework is introduced to address two issues prevailing in current service composition: interface incompatibility and performance. The reference framework applies active mediation to enhance efficient execution of applications employing composed services. As the number of services becomes large  the composed application imposes challenge on the service infrastructure management. A reliability model is introduced for building an automatic infra-structure management paradigm.

The paper by Wang  “Towards an Automatic IT Infrastructure Management Paradigm for Manufactory and Enterprise” describes about mission critical manufactory and enterprise IT infrastructure and on-line internet services require 24x7 availability and usually have an agreed Service Level Agreements (SLA) around its services offering. Currently  most enterprise and manufactory IT datacenters experience severe problems managing the large N tier  networked environments that these mission critical systems run on. Most of these problems arise from the complexity of the infrastructure (containing many moving parts) itself rather than building the applications. Maintainability of the IT system for long-term operational efficiency is largely missing. On the other hand  new IT technologies aiming at automating the deployment and maintenance of IT infrastructure are emerging. One promising technology is that of autonomic computing where the IT infrastructure and its components are self-configuring  self healing  self-optimizing and self-protecting and thus free of the management complexity to a large degree. This paper proposes a management model for enterprise IT infrastructure using self-managing paradigm for enterprise IT system and then describes the procedure for using the model as the basis for providing realistic Quality of Service (QoS) and SLA for IT infrastructure services. We also suggest this autonomic infrastructure management model be applied to the management of complex manufacturing systems  including the management of the enhanced agile/lean/integration and configurable manufacturing systems. To summarize the reference  it teaches about managing existing IT infrastructure based on self-managing paradigm.

Graupner in “Architecture for the Automated Management of Data Center IT Infrastructure” describes about IT Infrastructure Management in the Data Center. The overall goals of operating systems and IT infrastructure management in a data center are essentially similar: to execute applications and deliver computational services in a controlled and coordinated manner. Like in operating systems  portions of data center components must be selected  configured and transformed into resources that can drive applications. In a data center  these activities are performed by organizations of specialists who are concerned with decision-making and execution of IT management tasks. Management systems are directed towards supporting people  they provide little support for autonomous decision making and management task automation. The management of a data center is a complex and thus fragmented task. Higher-ordered tasks  such as resource allocation and scheduling  are performed as planning tasks by one group of specialists. Another group is concerned with configuration and deployment  while yet another is in charge of operational management. Different specializations have emerged for different domains. Servers  networks and storage are largely managed separately by different groups of specialists today. The paper discloses about managing of an existing IT system but fails to disclose about a modified IT landscape in a transformed enterprise.

A publication by IBM  “IT Transformation and Optimization Consulting Services - IT optimization solution framing” describes about a comprehensive roadmap designed to help reduce IT costs and complexity and improve service levels. The publication teaches about delivering an umbrella of services to address the complexities of evaluating  rationalizing and right-sizing an IT organization. The paper helps to enable more effective and efficient response to changing marketplace opportunities by facilitating the alignment of financial  business and IT objectives. The reference assists in lowering total cost of ownership through improved asset utilization and reduced asset acquisition.

Jain in “Network Infrastructure Management System & Sla Generation Tool” aims at giving a simplified solution to network device management at the data centers of various countries for the whole organization which also provides a graphical user interface for internal DNS server using MYSQL database in the backend. The reference teaches about a new automatic service level agreement (SLA) generation tool for a computer system and network monitoring software application (Nagios) and developed scripts for updating SharePoint’s database. The focus of the paper is network management and SLA generation.

A publication by Design  “On Network Infrastructure Management” describes about setting of industries ‘best practice’ standards for company IT policy and procedures  enhancing the availability and accessibility of information  promoting adaptability of network resources to target your business needs  ensuring interoperability between network infrastructure and external sources maintaining strict change control policies and procedures and ensuring the effective management and optimal operation of key network infrastructure devices.

The above mentioned prior arts fail to disclose an efficient method and system for re-architecting the WAN/LAN/SAN. Another drawback observed in the references cited above is that present systems do not consider existing data to compute new infrastructure taking into account other changes happening in the infrastructure environment. Yet another drawback of the above mentioned system is that these systems are needed to deploy in the customer network to collect data relating data centre management.

Hence need in the art to eradicate dependency on vendor for network transformation and optimization  creation of a robust and scalable network infrastructure and reduction of cost both in terms of operations and ownership.
