Open Sourcde And File Store Tech

Today, the standardization to the elemnet of communication such as high-performance PC, workstation and Internet is increasing. At the same time, operation systems including Linux are stronger and more stable, pc-cluster emerge as the times require。Generally, clusters are reliable, since every node in cluster has independent operating system kernel, one node failure don't affect to the function of the other nodes. In addition, we can improve further cluster's availability through using technique such as auto-negotiation, fail-over and data-recovery.The high performance-price-ration, updating and flexible structure are the mostly master advantages for cluster. Any technique used in PC can be used in cluster. We can also expand the cluster easily because of the flexibility of the structure. Most software based on open source is free, and...
