PRIMERGY Installation Release July, 2007 Zero Channel RAID ZCR card must be in correct slot that has the logic to enable it to utilise the onboard SCSI or SAS Most modern FSC motherboards colour code this blue Match LSI ZCR with LSI chip on motherboard Tx150S5,RX200S3 and Tx200S3 Embedded RAID Logic (EMRL): (the Adaptec term for it) SISL (the term LSI use) When the ZCR Controller is plugged in the dedicated PCI Slot, the EMRL activates the ChipSelect function for the AIC7901 / 7901 SCSI chip. By activating this function the SCSI Chip isn‘t shown on the PCI Bus any more. Aditionally the Interrupt channel is changed from a direct connection to the CPU to a connection to the ZCR Controller. So any operation is led directly to the RAID Controller which works off the requests LSI operates with S2 system boards with LSI chips... they tend to use the term SISL (SCSI Interrupt Steering Logic). Except that a different system board is involved with LSI chips, the operation is equivalent.
