K2Q28A Use Case
Enterprise VMware vSphere Scale-Out Storage with K2Q28A-HPE D6020 Enclosure
In a global financial services firm running a 100-node VMware vSphere cluster, storage I/O contention threatened application uptime. By integrating the K2Q28A-HPE D6020 Enclosure with Dual IO Modules via SAS lanes to HPE ProLiant hosts, IT teams rapidly added 60 hot-pluggable drives and redundant IO paths without downtime. Result: 4× higher IOPS, 99.999% availability, and seamless non-disruptive capacity expansion to meet growing virtual desktop and database performance SLAs.
Automated Disk-to-Disk Backup & Disaster Recovery for Remote Offices
A multinational retailer needed a reliable, low-latency backup target for 20 remote stores to meet compliance and RTO targets. Deploying K2Q28A-HPE D6020 Enclosures with Dual IO Modules at each site provided resilient dual-controller connectivity to an HPE StoreOnce backup cluster. Benefit: 3× faster backup windows, end-to-end encryption, and sub-4-hour recovery objectives, ensuring business continuity and regional data sovereignty.
Real-Time Big Data Ingestion for IoT Analytics on HPE ProLiant
A manufacturing enterprise streaming 50 TB/day of IoT sensor data required ultra-high throughput and low latency storage for real-time analytics. Connecting K2Q28A-HPE D6020 Enclosure with Dual IO Modules to HPE ProLiant DL380 Gen10 servers enabled sustained 12 GB/s sequential reads and sub-1 ms latency across large drive arrays. Outcome: accelerated predictive maintenance insights, 20% reduction in unplanned downtime, and data-driven operational excellence.
