HP 490093-001 StorageWorks SATA SAS Raid Controller

Product Description

The HP 490093-001 is a RAID controller card from HP's StorageWorks line, designed to provide essential data storage management features for compatible HP ProLiant servers. This controller allows for the configuration of multiple physical hard drives (both SATA and SAS interfaces) into logical arrays, offering benefits such as data redundancy and improved performance. By implementing RAID (Redundant Array of Independent Disks) technology, it protects against data loss in the event of a single drive failure and can accelerate data access speeds. This particular controller typically supports common RAID levels, including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for a balance of performance and redundancy), and RAID 10 (striped mirrors for high performance and redundancy). It connects to the server's motherboard via a PCIe interface, providing a robust link for data transfer between the drives and the system's memory. The controller manages the direct connection to the SATA or SAS drives, abstracting the complexity of individual drive management from the operating system. While specific server compatibility can vary, the HP 490093-001 is generally found in older generations of HP ProLiant servers where advanced integrated storage controllers might not have been standard. It serves as a crucial component for ensuring data integrity and optimizing storage performance in environments that rely on these specific server models. Its function is to provide a reliable foundation for server storage, essential for business continuity and application responsiveness.
