09N9540 - IBM ServeRAID 4L Ultra-160 SCSI RAID Controller Card Only

Description

The IBM 09N9540 is a ServeRAID controller card designed to provide robust hardware RAID capabilities for IBM server environments. Leveraging the PCI Express (PCIe) interface for high-speed communication with the server motherboard, this controller connects to storage devices using the Ultra160 SCSI protocol. This protocol was known for its high throughput in its era, making it suitable for demanding storage applications requiring fast data access and transfer rates. This controller offers hardware-based RAID processing, meaning it has its own dedicated processor and memory to manage RAID operations independently of the server's main CPU. This significantly improves performance, especially under heavy I/O loads, and reduces the burden on the system processor. The 09N9540 supports a comprehensive range of RAID levels, including RAID 0 (striping), RAID 1 (mirroring), RAID 5 (striping with parity), RAID 10 (striped mirrors), and RAID 50 (striped sets with parity), providing flexibility in configuring storage for optimal performance, redundancy, or a balance of both. Designed as a key component for IBM's server storage solutions, the 09N9540 enhances data protection against drive failures and boosts overall storage subsystem performance. It is essential for ensuring the availability and integrity of data for critical business applications running on IBM servers that utilize Ultra160 SCSI storage devices.
