Performance monitoring

The statistics feature of SFW provides I/O statistics to allow performance tuning to improve overall disk and system performance. Through the Online Monitoring window, hot spots are identified. A hot spot is an area of high I/O activity that may cause bottlenecks in I/O throughput. If a disk has these hot spots, consider moving one or more of its subdisks to another disk that shows below-average I/O activity. For more information on this topic, see the Storage Foundation Administrator's Guide.
