Efficient Operational Management of Enterprise File Server with File Size Distribution Model

摘要

Toward efficient operational management of enterprise file server, we propose an estimation method for relationship between file number and cumulative file size in descending order of file size based on a model for file size distribution. We develop the model by weighted summation of multiple log normal distribution based on AIC. File size data from technical and non-technical divisions of a company show that our model fits well with observed distribution, and that the estimated relationship can be utilized for cost-effective operational management of file server.
