Abstract

The IAA RAS is developing a data recording system for observations with radio telescopes of small diameter (13 m), which are also intended to realize the goals of the VLBI2010 international program. The main system goals are: • recording of eight data streams (with scalability up to 16) in the VDIF format with a data speed of 2 Gbps from each channel; • realizing data transfers to the Data Processing Centers at 10 Gbps transfer speed simultaneously with recording and buffering data; • storing session data up to 20 TB in size in a generic file structure with a set of disk pools
