IBM 13N2233 ServeRAID 8i SAS 256MB Cache RAID Controller Card

Product Description

The IBM 13N2233, part of the ServeRAID 8i family, is a dedicated hardware RAID controller designed to provide robust storage management and performance acceleration for IBM's server platforms. This card interfaces with SAS (Serial Attached SCSI) drives, offering higher throughput and scalability compared to traditional parallel SCSI. The inclusion of 256MB of onboard cache memory is crucial for RAID operations, as it allows the controller to buffer write data, significantly improving write performance and reducing latency by offloading these tasks from the CPU. This controller typically supports various RAID levels, such as RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for balanced performance and redundancy), and RAID 10 (striped mirrors for high performance and redundancy). The specific RAID levels supported would depend on the firmware version installed on the card. Its host interface is generally PCI-X, a high-speed bus prevalent in servers of the era, ensuring sufficient bandwidth for multiple high-performance SAS drives. Designed for integration into IBM eServer xSeries servers, the ServeRAID 8i controller simplifies the management of complex storage configurations. It allows administrators to create redundant arrays of independent disks (RAID) to protect against data loss due to drive failure, while also optimizing storage performance for demanding applications. This card is a key component for building reliable and high-performing storage subsystems in enterprise environments.
