A Global Read Hit occurs when a requested data block is found in a cache that is accessible across the distributed storage environment, making it readily available for retrieval without the need for a more time-consuming operation. In this case, when the remote local cache reads data during a Global Read Hit, it retrieves the data from the Global Cache.

The Global Cache is essentially a shared resource that holds frequently accessed data blocks from multiple nodes within a system like VPLEX. This mechanism is designed to enhance performance by reducing latency, as accessing data from the Global Cache is significantly faster than fetching it from primary storage systems or local disks. This system ensures that when data is being accessed frequently across different locations, it can efficiently be served from this shared cache, providing a quick response to the read request.

While the other options may represent possible sources of data in a storage environment, they do not align with the mechanism of a Global Read Hit, where leveraging the Global Cache is the primary objective for reducing latency and improving read operation efficiency.
