Product Description
The IBM 19K1104 ServeRAID-4L is a high-performance RAID controller card built upon the robust Ultra160 SCSI interface, offering enhanced data transfer speeds and reliability for enterprise storage needs. This controller is engineered to manage multiple SCSI hard drives, providing advanced data protection through various RAID configurations and boosting overall storage performance. Featuring a 64-bit PCI bus interface, the ServeRAID-4L ensures high bandwidth communication with the host system, which is crucial for handling the demands of enterprise-level I/O operations. The inclusion of 64MB of ECC (Error-Correcting Code) SDRAM cache memory further enhances performance by buffering data, reducing latency, and improving the efficiency of RAID operations. ECC memory ensures data integrity by detecting and correcting common types of internal data corruption. This controller supports essential RAID levels including RAID 0 for maximum performance through striping, RAID 1 for data mirroring and redundancy, and RAID 10 (a combination of striping and mirroring) for a balance of performance and fault tolerance. It is designed to connect to a significant number of SCSI devices, making it suitable for building scalable and reliable storage solutions within IBM eServer environments. The ServeRAID-4L is a key component for ensuring data availability and optimizing storage performance in critical business applications.
