Download The landscape of today's information infrastructure is continually changing. The amount of data that is being collected is increasing, and organizations are finding new ways to analyze, evaluate, and use the information that they collect. In addition, hardware trends are making it cost effective to capture new information sources and to automate data management. In the hardware arena especially, falling prices and increasing capacity for memory devices are reshaping the storage industry. Solid-state drives (SSDs), large amounts of RAM, and new I/O technologies influence raw system performance. The traditional paradigm that a system structure is built by a processor, cache, and global memory (dynamic RAM (DRAM)) is now being challenged by new trends. In addition, system virtualization can improve the utilization of hardware, software, networking, and storage resources. It can treat the physical resources as pools of virtual resources, which can in turn be dynamically allocated and reallocated in response to workload demands.
