Product Description
The IBM 21P7816 is a high-performance RAID controller card featuring an Ultra2 SCSI interface, designed for PCI-based servers. This controller is equipped with three 68-pin ports, enabling it to connect to multiple SCSI devices and manage them in a RAID configuration. Ultra2 SCSI offers significantly improved data transfer speeds and cable lengths compared to earlier SCSI standards, making it suitable for demanding storage applications. This card provides hardware-based RAID capabilities, allowing for the creation of redundant arrays of SCSI drives. Common RAID levels such as RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity), and RAID 10 (striped mirrors) are typically supported. By implementing RAID, users can achieve enhanced data protection against drive failures, increased storage performance, or a combination of both, depending on the chosen configuration. The 21P7816 is designed for environments where high-speed, reliable storage is critical. Its PCI interface connects to the motherboard's expansion slot, while the Ultra2 SCSI ports allow for the connection of internal or external SCSI hard drives, tape drives, or other storage peripherals. This controller is a robust solution for servers requiring advanced storage management and high throughput from their SCSI subsystems.
