A mid-market firm running VMware vSphere deployed the K2Q81A-HP StoreVirtual 4335 Hybrid SAN to host 500 concurrent VDI sessions. By leveraging high-performance SSD caching and automated tiering across SAS drives, login storms are reduced by 40% and sustained IOPS increase by 3×. Benefit: consistent sub-millisecond latency, simplified capacity scaling and a 30% reduction in overall VDI TCO.
A retail chain modernized its on-premises SQL Server environment using the K2Q81A-HP StoreVirtual 4335 Hybrid SAN. Automated SSD/HDD tiering delivers 2× faster transaction throughput for ERP workloads, while thin provisioning and snapshot-based backups cut nightly backup windows by 60%. Benefit: accelerated query performance, near-zero backup impact and SLA-driven data protection.
A financial services company implemented synchronous replication between two K2Q81A-HP StoreVirtual 4335 systems located in separate data centers. In the event of a site failure, automated failover restores operations within five minutes and maintains an RPO under 15 seconds. Benefit: robust compliance with regulatory mandates, seamless failover testing and measurable improvements in uptime SLAs.
