HP A9891A Smart Array Ultra320 SCSI 256MB PCI-X Raid Controller

Product Description

The HP A9891A is a high-performance Smart Array RAID controller designed for servers equipped with PCI-X slots. It leverages the Ultra320 SCSI interface, which was a leading standard for high-speed storage connectivity in its era, offering a maximum theoretical throughput of 320MB/s per channel. This controller is ideal for organizations that still utilize SCSI-based storage arrays or require compatibility with legacy server hardware. Equipped with 256MB of cache memory, the A9891A enhances storage performance by buffering data during write operations and speeding up read requests. This cache is crucial for improving the responsiveness of applications that rely on fast disk access, such as databases and file servers. The controller supports hardware RAID configurations, providing reliable data redundancy and fault tolerance through various RAID levels like RAID 0, 1, 5, and 10. This PCI-X card ensures robust data integrity and management capabilities for SCSI storage devices. It is a key component for maintaining and upgrading older server infrastructures that depend on SCSI technology. The A9891A represents HP's commitment to providing comprehensive storage solutions that cater to a wide range of server generations and interface requirements, ensuring data protection and performance for critical business data.
