HP 726821-B21 Smart Array SATA/600 12Gb/s SAS 4GB PCIe Raid Controller

Product Description

The HP Smart Array controller, identified by SKU 726821-B21, represents a significant advancement in enterprise storage management, offering robust data protection and high-performance capabilities. This controller is equipped with a substantial 4GB of cache memory, which dramatically accelerates read and write operations, leading to improved application performance and faster data processing. It supports both SATA/600 and the high-speed 12Gb/s SAS interfaces, providing broad compatibility with a wide range of storage devices and ensuring maximum data transfer rates. Designed for integration into HP ProLiant servers via a PCIe slot, the 726821-B21 leverages a high-bandwidth connection to the server's system bus. It supports a comprehensive suite of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This extensive support allows for flexible configuration of storage arrays, enabling administrators to tailor solutions for specific needs, whether prioritizing performance, data redundancy, or a balance between the two. The controller's advanced features are crucial for mission-critical applications, large databases, and virtualization environments where data integrity and availability are paramount. Further enhancing its enterprise-readiness, the HP 726821-B21 controller typically includes support for battery-backed write cache (BBWC) or flash-backed write cache (FBWC). This feature protects data in the cache during unexpected power outages or system failures, ensuring data consistency and preventing data loss. Additionally, the controller supports hot-plug drive functionality, allowing for the addition or removal of drives without interrupting server operations, which is essential for maintaining high availability and simplifying maintenance tasks in demanding data center environments.
