Effective capacity in data management refers to the actual capacity available for storage after accounting for various factors such as data reduction technologies, which include deduplication, compression, and thin provisioning. These technologies optimize the use of storage space by minimizing the amount of data that occupies the physical disks, thereby increasing the usable capacity of the storage system.

For instance, if a storage system shows a total physical capacity of 10TB, data reduction technologies might allow effective capacity to be significantly higher due to the reduction of redundant data, making it possible to store more unique data than the physical limits suggest. This represents a more accurate measure of how much data can actually be stored and accessed efficiently.

Other options indicate different aspects of storage and data management that do not align with the specific definition of effective capacity. For example, the total physical size of an appliance does not account for data reduction techniques and reflects only the raw capacity rather than usable capacity. Similarly, storage space available for immediate use refers to how much space is available at a given moment but does not consider data reduction benefits. The overall system performance rating is not directly related to capacity at all, rather it evaluates the speed and efficiency of the system's operations. Therefore, understanding effective capacity is crucial for proper storage management and
