Research on ways to reengineer a server room to improve the efficiency of IT infrastructure.

Abstract

The article considers a comprehensive re-engineering model for an outdated server room to improve the efficiency of an enterprise’s IT infrastructure. An audit of a typical legacy infrastructure was conducted, identifying key issues: hardware obsolescence, lack of fault tolerance, high operational costs, and low performance. A multi-level modernization model has been developed, which includes the design of a hybrid physical infrastructure with a dual-fabric network architecture (General Purpose and High-Performance Fabric) and specialized server pools. The transition to a software-defined platform based on virtualization and containerization systems is justified. A model for full management automation based on the "Infrastructure as Code" (IaC) paradigm using a stack of Terraform and Ansible tools is proposed. A comparative analysis of "before" and "after" metrics was carried out, which confirmed a significant increase in technical performance (response time reduction by 82%), improved reliability, and a substantial decrease in operational costs (60% reduction in electricity), proving the economic feasibility of the proposed solutions
