Product Description
The HP 010495-001 Smart Array controller is a powerful PCI-based RAID solution designed to manage SCSI storage devices. It features a Wide Ultra3 SCSI interface, also known as Ultra320 SCSI, which offers significantly higher data transfer rates compared to previous SCSI generations. This controller is equipped with 128MB of onboard cache memory, which acts as a buffer to speed up read and write operations, thereby improving the overall performance of the storage subsystem. The cache memory is crucial for handling demanding I/O workloads common in server environments. This RAID controller supports a comprehensive range of RAID levels, including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for balanced performance and redundancy), RAID 6 (striping with dual parity for enhanced redundancy), RAID 10 (striped mirrors), RAID 50 (striped RAID 5 sets), and RAID 60 (striped RAID 6 sets). This flexibility allows administrators to configure their storage arrays based on specific requirements for performance, data protection, or a combination of both. It enables the creation of fault-tolerant storage systems that can withstand single or multiple drive failures without data loss. Integration into servers is achieved via a standard PCI slot. The controller typically provides multiple SCSI connectors, often two internal and/or external connectors, to support a variety of drive configurations. It is designed to work with LVD (Low Voltage Differential) and SE (Single-Ended) SCSI drives, offering broad compatibility. The HP 010495-001 is a robust solution for enhancing storage reliability and performance in older server architectures that utilize SCSI technology.
