Zero Channel RAID
PCI-X slot 2 is prepared for the operation of a Zero Channel RAID (ZCR)
controller. Such a ZCR controller has no ports for hard disk drives. Installing the
ZCR controller in this PCI-X slot upgrades the SAS controller on the system
board to a fully featured RAID controller. Without this upgrade the SAS
controller on the system board supports only RAID 0 and RAID 1 configurations.
PCI, PCI-X, PCI Express interrupts
Each device connected to a PCI bus, a PCI-X bus or PCI Express can use up
to four interrupt signals depending on the functionality.
PCI and PCI-X buses use four lines named INTA to INTD, typically connected
to all devices on the bus in order to periodically balance interrupt load. An
interrupt signal may thereby be used simultaneously by multiple devices
(interrupt sharing).
PCI Express devices send their interrupts through messages. This avoids
restrictions in wiring.
