Product Features
Technical Overview
This adapter operates on a PCI Express 3.0 x8 interface, ensuring high bandwidth for data-intensive storage operations. The 12Gb/s SAS controller supports dual-port Mini-SAS HD connectors, each providing four lanes for a total of eight internal ports. This configuration allows direct attachment of up to eight SAS or SATA drives, supporting both performance-oriented and capacity-focused storage arrays.
RAID processing is handled entirely in hardware, offloading compute tasks from the host CPU. The supported RAID levels include striping (0), mirroring (1), parity-based (5,50), and nested (10) configurations, along with JBOD for individual drive management. The adapter is validated for server platforms and requires no external cache memory, reducing complexity and potential points of failure.
Relevant factors for this section include Host Interface, Controller Type, RAID Supported, Cache Memory. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
