## Data Storage System for VLBI Observations

Transactions of IAA RAS, issue 29, 28–32 (2014)

Keywords: e-VLBI, data storage, VLBI data transfer, virtual machines backup

### Abstract

Implementation of e-VLBI technology at the VLBI network Quasar started in 2008. Originally, the communication channel between observatories and the Correlation and Processing Center in St. Petersburg had not been able to transfer data with more than 100 Mbps rate. The bandwidth grown up to 400 Mbps in 2012 allowed the amount of the data routinely transfered to be considerably increased. Currently the daily data transfer capacity is from 200 Gb to 300 Gb. This fact raised a problem of a larger data storage. IAA RAS has built a new data storage system to solve this problem.
