726793-B21 Use Case
High-Density Virtualization Acceleration with HPE Smart Array P246br
In VMware or Hyper-V datacenters consolidating 100+ virtual machines per host, the HPE Smart Array P246br’s four 12 Gb/s internal SAS ports and 1 GB FBWC dramatically boost I/O throughput. By configuring RAID 10 for critical VM disks, IT administrators achieve up to 2× higher sustained IOPS and sub-1 ms latency under peak loads. The result is increased VM density, reduced storage bottlenecks, and a 30% improvement in TCO for large-scale virtualization deployments.
Enterprise Database Performance Optimization with 12 Gb/s SAS Controller
For SQL and NoSQL databases demanding sub-millisecond transactions, the HPE Smart Array P246br leverages its 12 Gb/s SAS bandwidth and battery-backed 1 GB cache to deliver consistent high throughput. Deployed in Oracle RAC or Microsoft SQL clusters, it accelerates random reads/writes by 40%, ensures data integrity during power loss, and minimizes lock contention. This translates into faster query response, seamless scaling under heavy OLTP workloads, and up to 25% lower latency for data-intensive applications.
Reliable Enterprise File Services & Data Protection Solution
In high-availability file server environments and SAN/NAS back-ends, the HPE Smart Array P246br provides robust RAID management for critical data sets. With support for RAID 5, 6, 10 and online spare configurations, plus 1 GB FBWC safeguarding write cache, organizations achieve 99.999% availability and accelerated rebuild times by 50%. The controller’s seamless integration with HPE InfoSight ensures proactive monitoring and reduces unplanned downtime, delivering business-critical file services with enhanced resilience and simplified storage administration.
