Product Description
The IBM 39R8818 ServeRAID controller is a high-performance storage adapter built for demanding enterprise environments. It supports the Ultra320 SCSI interface, enabling rapid data transfers up to 320 MB/s, which is critical for high-throughput applications and large storage arrays. The controller utilizes the PCI Express (PCIe) bus, providing a high-bandwidth, low-latency connection to the server's motherboard, ensuring efficient data flow. This controller integrates advanced hardware RAID capabilities, allowing for the creation of fault-tolerant and high-performance storage configurations. It supports various RAID levels, such as RAID 0 for performance, RAID 1 for mirroring, RAID 5 for parity-based striping, and RAID 10 for mirrored stripes, offering flexibility to meet specific application requirements. The substantial 256MB of onboard cache memory significantly boosts I/O performance by buffering data and accelerating write operations, reducing the load on the host system and improving overall application responsiveness. As part of IBM's ServeRAID product line, the 39R8818 is designed for seamless integration with IBM servers and management software. It provides robust data protection features, including support for hot-swapping drives, online capacity expansion, and RAID level migration, ensuring high availability and data integrity. This controller is an ideal choice for mission-critical applications that demand reliable, high-speed access to storage.
