What is Zero Channel RAID?

A type of RAID implementation in which a PCI RAID controller is designed to use the on-board SCSI channels of a motherboard to implement a cost-effective Hardware RAID solution.  The following are the two standards that enable such a design.
 

1. RAIDport - Adaptec Standard (ARO-1130xx series)
   RAIDport connector "behind" a PCI slot
    
2. SISL (System Interrupt Steering Logic) - Industry Standard
   A dedicated PCI slot with SISL implementation
   -  Mylex AcceleRAID 200 series
   -  AMI MegaRAID Express762 series
    
3. RAIDIOS - Intel RAID I/O Steering Specification
   - Supported on PCI or PCI-X bus technologies
   - Supported on most Adaptec chipsets
   
   Further FAQ's for RAIDIOS technology can be found at:
