804367-B21 Use Case
High-Density Virtualization for SMB Data Centers
In a mid-sized enterprise running 30+ virtual machines on HPE ProLiant Gen10 servers, the HPE Smart Array P204i-b SR Gen10 (4 Internal Lanes/1 GB Cache) 12G SAS Modular Controller consolidates VM storage traffic over four internal lanes. This scenario delivers sub-millisecond I/O latency, boosts VM density by up to 25%, and maintains enterprise-grade data protection with mirrored cache. Outcome: higher VM consolidation, predictable performance under peak load, and simplified storage management.
Accelerated OLTP Database Workloads
A financial services firm deploying mission-critical Microsoft SQL Server on dual HPE ProLiant Gen10 hosts leverages the P204i-b SR Gen10 controller to funnel high-speed 12G SAS disk arrays into a RAID 10 configuration. With 1 GB cache and battery-backed write protection, the controller delivers sustained 200 K IOPS for small-block transactions. Outcome: sub-5 ms write response times, 30% uplift in transaction throughput, and guaranteed data integrity during power events.
Fast Backup & Disaster Recovery for Virtualized Environments
An IT service provider implements daily snapshot backups and rapid restores across a cluster of HPE ProLiant Gen10 servers using the P204i-b SR Gen10 controller’s hardware-accelerated RAID features. By integrating with HPE StoreOnce and enabling online RAID level migration, backup windows shrink from 4 hours to under 1 hour and restore time objectives (RTO) drop by 60%. Outcome: minimized downtime, streamlined DR testing, and robust data resiliency for client SLAs.
