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

∙User-configurable RAID stripe sizing allows controller to optimize operations for operating systems and applications

∙User-configurable rebuild priority. Allows the user to keep RAID performance high while performing data rebuilds

∙Multi-threaded command processing and disk operations

∙Supports Tagged Command Queuing for optimal disk performance

∙Advanced load balancing and elevator seek for optimal disk performance

∙Intelligent algorithm to optimize RAID 5 writes

Data Protection Features

∙Support for RAID levels 0, 1, 0+1, 3, 5 and Spanning

∙Meets all of the RAID Advisory Board’s standards for RAID levels

∙Automatic sector re-mapping allows defective hard disk sectors to be re- mapped with data recovery

∙Automatic failed drive detection and transparent disk drive rebuild

∙Onboard buzzer sound audible alarms in the event of failure

∙Supports S.M.A.R.T. capable drives for predictive failure analysis messaging through SuperCheck GUI
