抄録

In fusion experiments, diagnostic control and logging devices are usually connected through the field bus, e.g. GP-IB. Internet technologies are often applied for their remote operation. All equipment and digitizers are driven by pre-programmed sequences, in which clocks and triggers give the essential timing for data acquisition. Data production rate and amount must be checked in comparison with the transfer and store rates. To store binary raw data safely, journaling file systems are preferably used with redundant disks (RAID) or mirroring mechanism, such as "rsync". A proper choice of the data compression method not only reduces the storage size but also improves the I/O throughputs. DBMS is even applicable to quick search or security around the table data.
