Adding a third expansion is not shown, but is discussed later.
Notes
1. Installing the “A” expansion with a secondary RAID controller board in PCI slot 2
supports three new disk arrays. Two arrays connect to the RAID controller and one
array connects to the RAID connector in the ISA I/O slot.
2. Installing the “B” expansion with a secondary RAID controller board in PCI slot 1
supports three new disk arrays. Two arrays connect to the RAID controller and one
array connects to the RAID connector in the ISA I/O slot.
Adding a third expansion to this InterRAID-8 configuration provides a maximum of four
RAID controller boards supporting twelve disk arrays (including the internal RAID
subsystem). The fourth RAID controller board will reside in either PCI slot 6 or 5,
depending on which slot is available. The third expansion will also use an available ISA I/O
slot and the RAID SCSI cable.
Channels 0, 1, and 2 on the primary RAID
controller board in PCI slot 3 supports two
external disk arrays and one internal RAID
subsystem.
