Abstract
In one example, a method for de-duplicating redundant data in a virtualized storage environment includes, in response to receipt of a write request that includes write data and a virtual memory address of the write data, mapping the virtual memory address to a physical memory address within a pooled storage capacity that includes a virtualization of a plurality of storage devices. Next, a determination is made that a second block of data included in the write data of the write request is identical to a first block of data that is stored in the pooled storage capacity. Finally, a pointer, rather than the second block of data, is stored in the pooled storage capacity at the physical memory address. The pointer points to the first block of data.
