823852-B21 Use Case
Accelerating Virtualized Workloads for Mid-Sized Enterprises
In a mid-sized enterprise consolidating servers on HPE ProLiant Gen10 hosts, the E208i-c SR controller aggregates eight NVMe/SATA SSDs in RAID 10 to deliver high I/O throughput for VMware vSphere VMs. This configuration boosts storage performance by up to 40%, minimizes VM boot storms, and simplifies management via HPE InfoSight, ensuring predictable SLAs and rapid capacity expansion.
Ensuring High-Availability for Mission-Critical Databases
A financial services firm deploys the Smart Array E208i-c SR on HPE Gen10 servers to protect Oracle and Microsoft SQL Server databases with hardware-accelerated RAID 1+0 and battery-backed write cache. By reducing storage latency to under 2 ms and automating drive failover, the solution guarantees 99.99% uptime and enables sub-minute recovery, safeguarding transactional integrity and regulatory compliance.
Optimizing Remote Branch Office Backup and Recovery
A retail chain equips remote branch servers with the E208i-c SR controller to locally cache daily backups on dual SSDs configured in RAID 1 before centralized replication. This approach cuts WAN bandwidth usage by 70%, accelerates restore operations to under five minutes, and offloads the primary data center, delivering resilient disaster recovery and consistent data protection across distributed sites.
