Q8B42A Use Case
Accelerated Enterprise Backup and Rapid Disaster Recovery
Scenario: A financial services firm with sub-minute RTO/RPO requirements deploys the Q8B42A-HPE NS SF100 Secondary Flash Base Array as a high-performance backup target. By offloading daily snapshots to secondary flash storage, the IT team reduces backup windows by 60% and enables instant failover in case of primary array failure. Benefit: Meets stringent recovery SLAs, minimizes potential data loss, and lowers OPEX by eliminating reliance on tape archives.
High-Performance Data Tiering for Real-Time Analytics
Scenario: A global manufacturer processes petabytes of IoT sensor data for predictive maintenance. Integrating the Q8B42A-HPE NS SF100 Secondary Flash Base Array as a hot tier in its Hadoop ecosystem accelerates random read/write workloads by 4× without impacting the primary SAN. Benefit: Delivers real-time analytics insights, optimizes data-processing throughput, and extends the lifespan of primary storage arrays.
Scalable VDI Boot-Storm Mitigation and Image Management
Scenario: A large university supports 1,500 virtual desktops and experiences severe login-storm bottlenecks each morning. By caching VDI images on the Q8B42A-HPE NS SF100 Secondary Flash Base Array, IT reduces login IOPS by 70% and maintains consistent user performance during peak hours. Benefit: Ensures predictable desktop performance, simplifies image provisioning, and reduces infrastructure TCO by offloading intensive I/O from the primary array.
