PowerFlex software uses the local disks and LAN of existing servers to create a virtual SAN that has all the benefits of external storage at a fraction of the cost and complexity. PowerFlex turns the existing local storage devices into shared block storage. For many workloads, PowerFlex storage is comparable to, or better than, external shared block storage.
PowerFlex software enables administrators to add or remove servers and capacity on-the-fly. The software immediately responds to the changes by rebalancing the storage distribution and achieving a layout that optimally suits the new configuration.
PowerFlex is designed and implemented with enterprise-grade resilience. In addition, the PowerFlex software features an efficient distributed self-healing process that overcomes media and server failures without requiring administrator involvement.
