This diagram shows one simplified example of an ASM interconnect network, intended to
illustrate the following key points:
The interconnect bus is a logically and physically distinct entity from any LAN connection.
Thus, ASM nodes are not required to be connected to the LAN that connects the focal point to the Director server.
The interconnect bus may not be used as a bridge between two LANs. This improves security and scalability.
Multiple hot-spare Director servers (or other management consoles) may exist for any
interconnect network. A Director server may also act as an interconnect node (compatible IBM hardware only),
allowing remote diagnosis and repair of the Director server itself from a hot-spare server. This provides greatly
improved availability and scalability.
Multiple hot-spare ASM focal points may exist for any interconnect network, allowing access to
ASM functionality even in the event of a complete failure of the default focal point. This provides improved
availability.
ASM interconnect networks may consist of up to 24 ISMPs or RSAs.
ASM interconnect networks may consist of up to 12 ASMPs or ASMAs, to which an additional 12
ISMPs or RSAs may be added.
Each ASM node on this diagram may be any xSeries server containing suitable ASM hardware.
