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
