摘 要:
For providers of web-based services, it is the best of times and the worst of times. The best of times because customers are spending more than ever on services. The worst of times because with traditional architectures, no matter how much capacity sites allocate, end user demand outstrips the horsepower and storage capacity of the server plant. The most important problem faced by Web infrastructure designers is how to provision the systems to cope with the incredibly rapid growth in number of users and storage capacity. Storage Area Networks (SANs), based on Fibre Channel switched fabrics, provide a powerful framework for building and managing server plant that is flexible, cost-effective and future-proof. In this paper, we analyze several scaling problems and show how SAN technology can address these issues, allowing the administrator to create Web infrastructure with unprecedented management, flexibility, performance and scaling characteristics.
