Data storage
Data storage has become a hot technology, the Internet is following the heat wave after another technology that will network into the data-centric era. This article will present the popular data storage technologies are summarized summary and data storage trends and future data storage technologies have made some subjective forecast.
Server data storage through three stages: direct plug-in storage (DAS), storage area networks (SAN), Network Attached Storage (NAS). DAS is a CPU-centric computing is king of the times, adapt to the initial development of the computer industry, and for SAN and NAS, the biggest difference in the result is technically a special agreement or use of existing IP technology, and data sharing and other issues were considered, SAN has the advantage of the initial consideration to solve the problem of network bandwidth, while the NAS is more emphasis on versatility and data sharing considerations.
Fibre Channel SAN infrastructure is currently the only option to establish, but with new technology and market dual role in the future may be used G/10G Ethernet and / or InfiniBand architecture (the IBA) to achieve the SAN.
Currently, several existing and future network interconnection standards are to fight for market and competition, Infiniband several obvious competitor is the PCI-X, G/10G Ethernet, Fibre Channel, Rapid I / O , HiPPI-6400 (GSN). In data storage solutions, Infiniband will face G/10G Ethernet technology challenges.
From the initial server to the current focus on data archiving solutions, we can generally see a computer network server architecture trend that the current internal bus architecture will gradually die out, the formation of switched (fabrics) network development the direction of the trend in the first, data storage, computing and I / O is combined into one, and the current data storage part is independent, the future will be the I / O and computing further separation, the formation of data storage, computing , I / O throughput of the three pillars of the situation, this is the real server network architecture, is to be the SUN company’s “network is the computer” thesis.
