SAN zoning is surely clear solution if Amanda has no plan for this problem and it's also a enough useful method for me for the moment. Thanks for your good advice. On the other hand, this solution brings a performance impedance problem between NW and FC. The most recent tape libraries, MSL6060 and so on, provide superior performance to GNIC. In this case, backup throughput is limited by network performance. But I will think about this when the time comes. -- Kazuhiro Takenaka <[email protected]>
