Performance Analysis and Massive Concurrent Access Response Test of Sichuan Top IT Vocational Institute Data Center Based on Virtualized Cloud Computing

摘要

Prior to 2017, the data center at Sichuan Top IT Vocational Institute adopted a centralized and traditional mode of "foundation-based support" with a high degree of coupling between network applications and physical servers. With the type of network services and business volume continuing to increase, the centralized and highly coupled architecture model cannot meet the growing demand for huge amounts of data and services, which exposed more and more disadvantages in resource integration, energy consumption, QoS, utilization, reliability, economy, manageability, security, etc. After full technical demonstration it is decided to adopt the H3C CAS virtualization cloud computing platform to transform and upgrade the data center1. The project has been completed its implementation in January 2017. After nearly three months of routine operating conditions and statistics analysis, in terms of energy consumption, qos, resource utilization, failure rate and so on it has achieved the intended expectations. Meanwhile a typical test program has been designed to simulate the mass visit, which verified that the system is fully capable of peak concurrent access.
