SuperTrak66 Technical Specifications
Performance-Related Features
• True hardware-based RAID
• Single IRQ per RAID I/O
• Intelligent cache dynamically configures itself
• Support for up to 128MB (minimum of 8MB required) of EDO RAM in one 72
pin SIMM socket
• Microprocessor offloads tasks to reduce system CPU utilization
• User-configurable cache parameters for each array: dirty threshold, write policy,
read ahead policy and flush policy
