The document discusses how the DataCore SANsymphony-V storage hypervisor can help virtualize business-critical applications without performance issues by managing resources across storage systems. It provides adaptive caching, auto-tiering of storage pools from different disk assets, and synchronous mirroring between fault domains. This allows applications to perform predictably even when virtualized, improves throughput by up to 5 times, and provides 99.999% availability. The storage hypervisor is a better solution than expensive hardware modifications to deal with virtualization issues, and provides benefits like preventing downtime and simplifying management of distributed infrastructure.
