FAQ

PowerStore supports block, file, and container workloads with protocols like NVMe-oF, iSCSI, SMB, and NFS. It’s ideal for databases (OLTP/OLAP), virtualized environments, and file-based workloads that need sub-millisecond latency, high throughput, and simplified management.

NVMe (Non-Volatile Memory Express) is a high-speed protocol built for SSDs. PowerStore uses end-to-end NVMe, NVMe-oF networking, and dual active controllers to deliver lower latency, higher efficiency, and better performance than hybrid HDD/SSD arrays.

PowerStore delivers 99.9999% availability with redundant hardware and active/active controllers. It offers local, remote, and cloud-based data protection, plus immutable snapshots, encryption, and role-based access controls to safeguard mission-critical applications.

PowerStore T models use TLC flash for performance-heavy workloads like databases and VMs, while Q models use QLC flash for cost-effective, capacity-driven needs like file repositories and archiving. Both deliver NVMe performance, scalability, and data reduction.

PowerStore lowers TCO with guaranteed 5:1 data reduction, higher density vs. spinning/hybrid arrays, and automation that saves admin hours. It supports scale-up and scale-out growth without disruption and includes Lifecycle Extension with ProSupport for long-term savings.

PowerStore Metro Volume ensures continuous availability across sites with automated failover and a free third-site witness. It’s easy to set up and delivers zero-disruption business continuity for VMware, Linux, and Windows environments.
