Assessment of Hypervisor and Shared Storage for Cloud Computing Server

This paper introduces the Open filer operation system to setup a network storage environment, and to build five different private small-cloud computing servers (PSCCS). Then by using the iSCSI storage technique through the TCP/IP protocol to explore the accessing assessments of the Open filer storage device for each feasible cloud computing system is undertaken. This includes comparing reading efficiency between storage device and cache. This storage technique can alleviate each physical host´s burden, and also becomes a storage method of shared resources. These assessments can provide optimized solutions to small and medium enterprises (SMEs), schools, and social groups in choosing a private small-cloud computing server. Experiment results of accessing assessment of the Open filer storage device shows that cloud server VMware vSphere V (ESX server) has the highest performance rate, but comes with high costs, alternatively free software Proxmox VE is the best choice among private small-cloud computing server.
