Deduplication and compression logic is applied to all writes in PowerStore, including VDI workloads. This logic ensures that data is stored in the most efficient way possible. Data reduction algorithms run automatically and cannot be disabled by the user. With PowerStoreOS 2.0, PowerStore may defer deduplication operations when the system experiences a period of heavy I/O so workload performance is prioritized. When deferral occurs, compression continues uninterrupted. Once deduplication resumes, the deduplication algorithm is applied to blocks that were skipped for further data reduction if achievable.
Data savings achieved with instant clone pools is high because desktops are cloned from a gold image. As workers log into their virtual desktops and generate unique data during steady state, expect data savings to decrease. The amount of data savings realized over time on PowerStore will vary based the type and quantity of new unique data written to the storage by VDI users.
