网络业务系统的新瓶颈 随着光通信和集成电路技术的发展,今天的通信网络和设备已经可以支持上百G的带宽,局域网的速率更是达到了1OG甚至更高。在一定的范围内,带宽已经不再是网络业务系统的瓶颈。电信网和互联网的相互融合,使得传统的计算机网络中各业务系统向着电信级的高性能、高可靠性方向发展。而在整个业务系统中,存储系统因其特殊的作用而日益成为整个业务系统的新瓶颈,业务系统的数据保护和灾难事件发生时的容错和恢复能力已成为网络运营商和企业考虑的首要问题。
New bottleneck of network business system With the development of optical communication and integrated circuit technology, today’s communication networks and devices have been able to support the bandwidth of hundreds of G, LAN speed is even reached 1OG or even higher. In a certain range, bandwidth is no longer the bottleneck of network business systems. The integration of telecom network and Internet makes each business system in the traditional computer network develop toward the carrier-class high performance and high reliability. In the whole business system, storage systems are increasingly becoming the new bottleneck of the entire business system because of their special functions. Data protection of business systems and fault tolerance and resilience in the event of disasters have become the primary issues for network operators and enterprises .
