Product Description
The HP K2Q90AR is a high-performance Host Bus Adapter (HBA) designed to provide robust connectivity for servers and storage systems. This controller card features dual interfaces: one supporting 6Gb/s SAS (Serial Attached SCSI) and the other supporting 8Gb/s Fibre Channel (FC). SAS is a standard interface for connecting storage devices like hard drives and SSDs to servers, offering high throughput and reliability. Fibre Channel is a high-speed networking technology primarily used for Storage Area Networks (SANs), enabling efficient and low-latency access to shared storage resources. With a substantial 4GB of onboard cache memory, this controller is optimized to handle demanding I/O operations, improving overall system performance by buffering data and reducing latency. The combination of SAS and Fibre Channel interfaces on a single card provides significant flexibility, allowing it to connect to both direct-attached storage (DAS) and SAN environments. This makes it a versatile solution for enterprise servers, storage arrays, and other data-intensive applications. The controller utilizes a PCIe (Peripheral Component Interconnect Express) interface, ensuring high bandwidth communication with the host system's motherboard. The HP K2Q90AR is engineered for reliability and performance, making it a critical component for environments requiring fast, dependable access to storage, such as database servers, virtualization hosts, and high-performance computing clusters.
