Windows Server Windows Server Unified management in Windows Admin Center is an elegant browser-based HCI remote management interface that includes software-defined network configuration and monitoring. Storage Spaces protect your data from drive failures and extend storage over time as you add drives to your servers. Mirror-accelerated parity lets you create volumes that are part mirror and part parity for 2x better performance on storage spaces direct deployments. Writes land first in the mirrored portion and are gradually moved into the parity portion. Nested Mirror Accelerated parity enables two-node clusters at the edge to survive multiple simultaneous failures. Storage class memory support for new generation of server hardware including storage class memory, which drastically improves performance for server applications. Storage Replica provides storage-agnostic, block-level, and asynchronous and synchronous replication between servers for disaster recovery and allows stretching of a failover cluster for high availability.
