Product Description
The IBM 13N2227, part of the ServeRAID 8i family, is a sophisticated RAID controller designed to enhance the storage capabilities of IBM servers. It leverages Serial Attached SCSI (SAS) technology, offering higher performance, scalability, and reliability compared to older parallel SCSI interfaces. This controller supports a range of RAID levels, including 0, 1, 5, 10, and 50, providing flexibility in configuring storage arrays to balance performance, redundancy, and capacity according to specific application needs. Equipped with 256MB of onboard cache memory, the ServeRAID 8i accelerates read and write operations by temporarily storing frequently accessed data. This cache is crucial for improving the overall responsiveness of storage subsystems, especially in I/O-intensive environments. Furthermore, the controller typically supports a Battery Backup Unit (BBU) or similar protection mechanism, which safeguards the data in the cache during power outages, preventing data loss and ensuring data integrity upon system restart. Designed for integration into IBM server platforms, the 13N2227 provides robust data protection features essential for business-critical data. It allows for the management of both SAS and SATA drives, offering flexibility in drive selection. This RAID controller is a key component for organizations seeking to build reliable, high-performance storage solutions within their IBM server infrastructure, ensuring data availability and operational continuity.
