Abstract

A method and system for optimizing a distributed enterprise information technology (IT) network infrastructure is disclosed, wherein the IT infrastructure comprises at least one server, at least one storage element, and at least one network element. The method comprises collecting data and arranging the collected data pertaining to an existing state of the information technology network infrastructure in a first set of templates. The method further comprises mapping the existing state and a new state of at least one of the at least one server and at least one storage element with an existing set of network elements using the first set of templates to form a second set of templates, wherein the method further comprises of planning the new state of the IT network infrastructure for transformation using the first set of templates and the second set of templates, the new state being an optimized state.

Claims

1. A computer-implemented method for optimizing distributed enterprise information technology (IT) network infrastructure, the IT infrastructure comprising at least one server, at least one storage element, and at least one network element, the method comprising:

collecting data and arranging the collected data pertaining to an existing state of the information technology network infrastructure in a first set of templates;

mapping the existing state and a new state of at least one of the at least one server and the at least one storage element with an existing set of the at least one network element using the first set of templates to form a second set of templates; and

planning the new state of the IT network infrastructure for transformation using the first set of templates and the second set of templates, the new state being an optimized state of the IT network infrastructure.

2. The method of claim 1, wherein the second set of templates comprises information obtained by mapping the existing state to the new state of at least one of the servers, storage elements and existing set of network elements.

3. The method of claim 1, wherein the optimized state is measured by at least one of QoS, QoE, cost, complexity, and space of the IT Network infrastructure and the optimized IT Network Infrastructure.

4. The method of claim 1, wherein the first set of templates includes information pertaining to servers, network components, storage devices, applications, switches, port connectivity, WAN bandwidth and data centers.

5. The method of claim 4, wherein the information pertaining to network components includes at least one of slots per component, ports per slot, ports bandwidth, and connectivity information.

6. The method of claim 4, wherein the information pertaining to applications includes at least one type of the application, protocols used for communication, number of users supported, and bandwidth per user.

7. The method of claim 4, further comprises extracting said information from a report or a log pertaining to the network components or applications when the information is not available directly and filling suitable assumptions is case of missing information.

8. The method of claim 1, wherein the second set of templates includes analyzed data pertaining to the at least network component with their respective critical parameters.

9. The method of claim 8, wherein the critical parameters include at least one of throughput, ports availability, and ports bandwidth.

10. The method of claim 1, further comprising reducing operational cost by consolidating multiple data centers to fewer data centers and bringing down the server sprawl.

11. The method of claim 1, wherein the distributed enterprise information technology (IT) network infrastructure is optimized by a processor executing the steps of:

collecting data pertaining to the one or more of IP traffic pattern, Data traffic pattern, existing network topology, information about number of applications/services running, protocols used for communication, Quality of Service (QoS) requirement of applications, number of users accessing the applications/services, and Quality of Experience (QoE) in the current network;

analyzing the collected data by calculating the average and peak wide area network bandwidth required for the servers; and

planning post optimized state of the information technology network infrastructure by verifying whether the existing average and peak wide area network bandwidth match with the values determined in the analysis step.

12. The method of claim 11, further comprising upgrading the wide area network bandwidth if existing wide area network bandwidth is not matching with the analytical derivative of a required value and determining possible causes for bottlenecks if existing wide area network bandwidth is matching with the analytical derivative of required value.
