Ensuring that business-critical data is available when needed is an ever-growing need in IT. Your systems must store massive amounts of data quickly and retrieve it efficiently. Simultaneously, you must use new technologies that can improve efficiency and take advantage of these technologies within limited budgets. One measure of growing efficiency in recent years is CPU processing power, which far exceeds growth in disk input/output (I/O). For this reason, disk I/O is often the reason for bottlenecks in high-performance applications.
16 Gb Fibre Channel connectivity combined with other storage technologies such as solid-state drives and storage tiering can help to balance the performance of storage subsystem with the server processing capabilities.
This IBM® Redpaper™ discusses server performance disbalance that can be found in typical application environments, and how to address this issue with the 16 Gb Fibre Channel technology to provide required levels of performance and availability for the storage-intensive applications.
