IBM 02R0970 ServeRAID Ultra320 SCSI Raid Controller

Product Description

The IBM 02R0970 is a high-performance ServeRAID controller designed to manage and optimize storage using Ultra320 SCSI drives. This controller represents the pinnacle of SCSI technology, offering significantly higher data transfer rates (up to 320MB/s per channel) compared to previous SCSI generations. It is equipped to handle demanding enterprise workloads by providing advanced RAID capabilities, including support for a wide array of RAID levels such as RAID 0, 1, 5, 6, 10, 50, and 60. This extensive RAID support allows for flexible configurations that balance performance, data redundancy, and capacity requirements. The controller typically features a substantial amount of onboard cache memory (often 128MB or 256MB) and a dedicated RAID processor. This hardware-based RAID solution offloads complex RAID calculations from the server's CPU, ensuring consistent and high performance, especially under heavy I/O loads. The use of a PCI-X 133MHz interface provides the necessary bandwidth to keep pace with the Ultra320 SCSI drives, making it suitable for mission-critical applications that require fast and reliable storage access. Designed for integration into IBM eServer xSeries servers, the ServeRAID Ultra320 controller is a robust solution for building high-availability storage subsystems. It enables organizations to protect their data against drive failures through various mirroring and parity schemes while simultaneously improving storage performance through striping and caching. This card is essential for servers running applications that demand high throughput and data integrity from their SCSI storage arrays.
