HPE 804331-B21 P408i-a SR Gen10 SAS Controller
Overview
The HPE 804331-B21 is an enterprise-grade Smart Array P408i-a SR Gen10 modular controller, engineered to provide high-performance storage connectivity and robust data protection for HPE ProLiant Gen10 servers. It is specifically designed for IT environments that require maximum storage performance and reliability for critical applications without consuming a standard PCIe expansion slot. This controller addresses the need for accelerated I/O in messaging, database, or general server workloads. At its core, the controller leverages 12Gb/s SAS and PCIe 3.0 technologies to eliminate storage bottlenecks and enhance server efficiency. Its key performance driver is the integrated 2 GB Flash-Backed Write Cache (FBWC), which significantly accelerates write-intensive application performance and protects data in the event of a power loss. The P408i-a supports a comprehensive range of advanced RAID levels, ensuring flexible and resilient data protection schemes tailored to specific business needs. Designed as a type-a modular controller, this unit fits into a dedicated slot on the server system board, preserving valuable PCIe slots for other expansion cards. It supports Mixed Mode, allowing it to operate in both RAID and HBA modes simultaneously for greater flexibility. Management is streamlined through HPE's suite of storage utilities, providing administrators with a secure and efficient platform for managing evolving data storage requirements.
