Efficiency Of Is Resource

Capacity Utilization Most computing systems operate at less than maximum capacity most of the time. However, allowance must be made for loading during peak periods. Margins are usually built into capacity planning to prevent performance degradation or data loss when hardware and software facilities begin to be pushed to their limits. If the system is properly managed, unused capacity can be minimized.

When planning costs, IS managers must distinguish between the theoretical and used capacity of a system. Failure to account for this is one of the more frequent causes of cost overruns among users moving to new systems. It may be necessary to add additional capacity to handle peak workloads. For example, properly managed disk storage subsystems may have high levels of occupancy (85 percent and over is the norm in efficient installations). There is a close relationship between data volumes used in applications and actual disk capacity. Inactive data is more frequently dumped to tape, thus reducing disk capacity requirements and corresponding hardware costs. If a system operates less efficiently, capacity requirements, and hence costs, can be substantially higher even if workloads are the same.
