Product Description

The Dell 9K2C2, identified as the Perc H755N Front NVMe RAID Controller, is a high-performance component designed to enhance storage capabilities within Dell servers. It leverages the speed of NVMe (Non-Volatile Memory Express) technology, which is optimized for solid-state drives and offers significantly lower latency and higher throughput compared to traditional SAS or SATA interfaces. This controller is specifically designed for front-mounted configurations, indicating its intended placement within certain server chassis for direct access to drives. A key feature of the H755N is its 8Gb Non-Volatile Flash Backed Write Cache (FBWC). This cache memory is crucial for RAID controllers as it accelerates write operations by temporarily storing data before it is written to the drives. The 'non-volatile' aspect means that data in the cache is protected against power loss by a flash backup, ensuring data integrity even in the event of an unexpected shutdown. The controller supports the latest PCI-E Gen 4 interface, providing the maximum bandwidth available from modern server platforms, which is essential for maximizing the performance of NVMe SSDs. This RAID controller is engineered to support various RAID levels (e.g., RAID 0, 1, 5, 6, 10, 50, 60), allowing administrators to configure storage arrays based on their specific needs for performance, redundancy, and capacity. By combining NVMe technology with a powerful RAID controller and fast FBWC, the Dell 9K2C2 enables extremely high-performance storage solutions, making it suitable for demanding applications such as large databases, virtualization environments, high-performance computing, and video editing workstations where I/O performance is critical.
