LSI puts RAID on a chip
This month, LSI Logic began shipping a single-chip PCI-SCSI RAID I/O processor. The SYM53C1510 chip, which replaces the four or five chips typically required, is designed for use on motherboards or in low-cost adapters. Potential benefits include reduced costs, lower power requirements, higher reliability, and fewer board-level layers.
The chip integrates two Ultra2 SCSI channels, a message-passing unit, memory controller interface that supports EDO RAM, and hardware XOR support for RAID 5 implementations. The chip is targeted at mid=range applications (e.g., five to 30 drives).
