Product Description
The Dell 405-ABCQ is a Dell PowerEdge RAID Controller (PERC) H355, a high-performance storage adapter designed for Dell PowerEdge servers. This controller utilizes a PCIe Gen 4 x16 interface, providing significantly increased bandwidth compared to previous generations, ensuring rapid data transfer between the controller and the server's motherboard. It features 16 internal ports that support both 12Gb/s SAS and 6Gb/s SATA drives, offering broad compatibility and high-speed connectivity for storage devices. The PERC H355 supports essential RAID levels including RAID 0, 1, 10, 5, and 50, enabling administrators to configure storage arrays that provide a balance of performance, data redundancy, and capacity. Unlike some higher-end PERC controllers, the H355 is a cacheless controller, meaning it relies on the host system's CPU and memory for RAID operations. This design can be cost-effective for certain workloads where extreme caching performance is not a primary requirement. Designed specifically for Dell PowerEdge servers, the 405-ABCQ ensures seamless integration and optimal performance within the Dell ecosystem. It is a suitable choice for entry-level to mid-range servers requiring reliable RAID functionality and high-speed SAS/SATA connectivity for applications such as file servers, web servers, and general-purpose computing. Its robust connectivity and support for key RAID levels make it a versatile storage solution.
