Dell EMC Unity XT midrange platforms are shared storage solutions that provide low latency, high throughput, and low management overhead for SQL Server workloads. All Unity XT systems employ a dual-active architecture that uses dual storage processors (SPs) to serve host I/O and run data operations in an active/active manner. Unity XT dual SPs use full 12 Gb SAS back-end connectivity and a patented multicore architected operating environment to deliver high performance and efficiency. Disk array enclosures provide additional storage capacity.
The Unity XT family includes Unity XT All-Flash, Unity XT Hybrid, UnityVSA, and Unity Cloud Edition.
Intel processor-based Unity XT Hybrid and Unity XT All-Flash storage systems implement an integrated architecture for block, file, and VMware VVols, with concurrent support for native network-attached storage (NAS), iSCSI, and Fibre Channel (FC) protocols. Unity XT Hybrid and Unity XT All-Flash platforms are NVMe-ready.
Unity XT Hybrid systems are designed for multicloud environments. They provide:
Unity XT All-Flash systems deliver speed, efficiency, and multicloud support, providing:
Unity XT All-Flash unified storage for SQL Server provides more details about Unity XT All-Flash systems.
The UnityVSA system is software-defined virtual storage for VMware ESXi environments, using server-based, shared, or cloud storage capacity. UnityVSA HA, a dual-storage-processor deployment of UnityVSA, provides additional resiliency against disaster. UnityVSA storage provides:
For file synchronization and disaster recovery operations in the cloud, the Unity XT family includes Unity Cloud Edition, which provides:
