758801-B21 Use Case
Accelerating Virtual Machine Performance in Enterprise Data Centers
Scenario: A global enterprise deploys VMware vSphere clusters on HPE ProLiant Gen10 servers. Integrating the 758801-B21 Smart Array P240NR/1GB Controller provides a dedicated 1 GB flash-backed write cache and high-speed SAS connectivity. Outcome: VM boot storms are reduced by 40%, random I/O performance improves by 50%, and sub-millisecond latency ensures consistent 99.999% SLA compliance.
High-Performance SQL Server Transactions for Retail Point-of-Sale Networks
Scenario: A national retail chain operates hundreds of PoS terminals backed by on-premises SQL Server on HPE ProLiant servers. The P240NR/1GB Controller’s non-volatile write cache and optimized read/write algorithms minimize latency under heavy transactional loads. Outcome: Query response times drop by 30%, transaction availability reaches 99.9%, and peak-season bottlenecks are eliminated.
Optimizing Hyper-Converged Infrastructure Scalability and Resilience
Scenario: An IT services provider builds a VMware vSAN cluster with HPE ProLiant nodes equipped with the 758801-B21 P240NR/1GB Controller. The controller delivers consistent cache acceleration across distributed storage, speeding rebuilds and protecting against drive failures. Outcome: Data rebuild times accelerate by 25%, cluster resilience is enhanced with uninterrupted I/O under drive loss, and performance scales linearly as nodes are added.
