Product Description
The HP 399550-B21 is a sophisticated Storage Area Network (SAN) controller engineered to provide robust data management and high-speed connectivity for servers. It leverages the SAS (Serial Attached SCSI) interface, known for its reliability and performance, alongside SATA compatibility, offering flexibility in drive selection. The integrated 256MB cache memory plays a crucial role in buffering data, thereby improving read/write operations and overall system responsiveness, especially under heavy workloads. This PCIe-based controller is designed for easy integration into standard server expansion slots, making it a suitable upgrade for existing infrastructure or a key component in new builds. It supports a range of RAID (Redundant Array of Independent Disks) levels, allowing administrators to configure storage for optimal performance, data redundancy, or a balance of both. Features such as hot-plug support ensure that drives can be added or removed without system downtime, enhancing serviceability and minimizing disruptions. With its support for 3Gb/s SAS and SATA/150 interfaces, the 399550-B21 is capable of handling demanding enterprise applications that require fast and reliable access to storage. Its advanced functionality helps protect data against drive failures through various RAID configurations, while also optimizing throughput for applications like databases, virtualization, and high-performance computing. This controller represents a significant step up in storage management capabilities for businesses seeking enhanced data integrity and operational efficiency.
