The I/O storage system is a critical component of any SQL Server environment. Sizing and configuring a storage system without understanding the I/O requirements can result in poor performance, insufficient capacity, or both. Analyzing performance in an existing environment using a tool like Live Optics can help define the I/O requirements. Your Dell Technologies representative can assist with Live Optics data collection and analysis. For best results, capture performance statistics for a period of at least 24 hours that includes the system peak workload. Also include special operational circumstances such as critical business and maintenance activities.
