Product Description
The HP Smart Array H240ar HBA (749976-B21) is a versatile storage controller designed to provide high-performance connectivity for servers. It supports both SATA and SAS drives, offering flexibility in storage configurations. The H240ar operates at 6Gb/s for SATA and a faster 12Gb/s for SAS, ensuring that storage devices can perform at their maximum potential. This makes it suitable for a wide range of applications, from general-purpose servers to more demanding storage solutions. This HBA utilizes a PCIe 3.0 x8 interface, providing ample bandwidth for data transfer between the storage devices and the server's CPU. The inclusion of 4GB of cache memory significantly accelerates storage operations by buffering data, reducing latency, and improving the overall responsiveness of the storage subsystem. This cache is crucial for workloads that involve frequent read and write operations, such as databases and virtualization environments. The 2-port design of the H240ar allows for easy expansion and connection to multiple storage devices or backplanes. Its 'ar' designation typically indicates an 'array' configuration, suggesting it's optimized for direct-attached storage within a server. This controller is a key component for building reliable and high-performing storage solutions within HP ProLiant servers.
