IBM 19K1104-00 Serveraid 4L Ultra160 SCSI Raid Controller

Product Description

The IBM 19K1104-00 Serveraid 4L is a dedicated RAID controller designed to manage and protect data stored on SCSI hard drives. It interfaces with servers via a standard PCI slot and utilizes the Ultra160 SCSI bus, offering a reliable solution for storage management in environments that rely on SCSI technology. This controller supports various RAID levels, including 0, 1, 5, and 10, allowing administrators to configure their storage for optimal performance, data redundancy, or a balance of both. By implementing RAID configurations, the Serveraid 4L enhances data availability and fault tolerance. For instance, RAID 1 (mirroring) provides data redundancy by writing identical data to two drives, ensuring that the system can continue operating even if one drive fails. RAID 5 offers a balance of performance and redundancy with striping and parity, while RAID 10 combines mirroring and striping for high performance and protection. The Ultra160 SCSI interface ensures a high data transfer rate for these SCSI drives. This controller is a crucial component for servers requiring robust storage solutions, particularly in older infrastructure that may still utilize SCSI drives. It provides the necessary intelligence to manage multiple drives as a single logical unit, simplifying storage administration and improving the overall reliability and performance of the server's storage subsystem. Its inclusion ensures that data integrity is maintained and that potential drive failures do not lead to data loss or significant downtime.
