Product Description
The IBM 46M0964 is a high-performance ServeRAID controller designed to manage Serial ATA (SATA) drives within IBM server environments. Leveraging the SATA/600 (6Gb/s) interface, it offers significantly faster data transfer rates compared to previous SATA generations, enabling efficient handling of modern high-capacity hard drives and SSDs. The controller connects to the server's motherboard via a PCI Express 2.0 x8 bus, providing ample bandwidth for multiple drives and demanding I/O operations. This controller supports a comprehensive suite of RAID levels, including RAID 0 for performance striping, RAID 1 for mirroring, RAID 5 and 50 for parity-based redundancy with good read performance, and RAID 10 for a combination of performance and redundancy. With standard onboard cache memory (often 256MB, with options for larger sizes or battery backup units), it accelerates read and write operations by buffering data, reducing latency and improving overall system responsiveness. The controller typically supports up to eight internal SATA drives, allowing for flexible storage configurations. Designed specifically for IBM System x servers, the 46M0964 ensures seamless integration and optimal performance within the IBM ecosystem. The optional Battery Backup Unit (BBU) is a critical feature for enterprise deployments, as it protects the data in the controller's cache memory in the event of a power outage, preventing data loss and ensuring data integrity. This makes the IBM 46M0964 a robust and reliable choice for building high-capacity, cost-effective, and protected storage solutions.
