Product Description
The HP Smart Array P420-1GB-HP is an advanced storage controller designed to enhance the performance and reliability of HP ProLiant server storage configurations. This model is distinguished by its 1GB of cache memory, which significantly improves I/O performance, especially in write-intensive workloads, by buffering data effectively. It supports both SAS (Serial Attached SCSI) and SATA (Serial ATA) drives at a 6Gb/s interface speed, offering flexibility in drive selection and ensuring high data throughput. The controller provides comprehensive RAID support, including levels 0, 1, 5, 6, 10, 50, and 60, enabling administrators to create storage arrays that balance performance, data protection, and capacity according to their specific requirements. Connected via a PCI Express 3.0 x8 bus, the P420i controller offers ample bandwidth for high-speed data transfers. The '1GB-HP' designation often implies the inclusion of a Flash-Backed Write Cache (FBWC) or similar technology, which protects cached data in the event of a power loss, further enhancing data integrity and performance. Its mezzanine form factor is designed for integration into specific HP server models.
