749975-B21 Use Case
Accelerating VMware vSphere Clusters with HP Smart Array P246br/1G FIO Controller
In a mid-sized enterprise running VMware vSphere on ProLiant DL380 Gen10 servers, integrating the 749975-B21 HP Smart Array P246br/1G FIO Controller delivers up to 40% lower VM I/O latency and seamless failover. By offloading RAID management and optimizing flash I/O, IT teams achieve consistent VM performance under peak loads and simplify storage administration while ensuring 99.99% uptime.
Boosting SQL Database Throughput for Transactional Workloads
A financial services firm uses the P246br/1G FIO Controller to accelerate an on-premises Microsoft SQL Server cluster. Leveraging its full-height 1GB cache and Flash-Optimized I/O, the controller cuts 95th-percentile query response times by 60%, supports 50% more concurrent transactions, and maintains data integrity with hardware-assisted RAID protection.
Implementing Hybrid Flash-HDD Tiering for Cost-Effective Storage
An SMB deploys the 749975-B21 controller in a ProLiant DL360 storage node to manage mixed SSD and HDD arrays. Automated tiering moves hot data to flash and archives cold data to high-capacity disks, reducing overall storage spend by 30% while boosting random I/O performance by 3x and extending drive lifespan through optimized write patterns.
