The Intel® Server Board SE7501HG2 is capable of supporting zero channel RAID add-in cards. The ZCR cards are only supported in slot 2 on the P64-B segment.
The ZCR add-in cards leverage the on-board SCSI controller along with their own built-in intelligence to provide a complete RAID controller subsystem on-board. The baseboard uses an implementation commonly referred to as RAID I/O Steering (RAIDIOS) specification version 1.0 to support this feature.
When one of the supported RAID cards is installed, the SCSI interrupts are routed to the RAID adapter instead of to the PCI interrupt controller. In addition, the IDSEL of the SCSI controller is not driven to the controller and thus will not respond as an on board device. The host-based I/O device is effectively hidden from the system.
For a list of supported Zero Channel RAID cards, please refer to the tested hardware and operating system list.
