Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

1 Overview
The Cluster I/O Protocols (CIP) subsystem provides a configuration and management interface for
I/O on certain HP Integrity NonStop systems. To find out if your system supports CIP, see appropriate
planning guide; for example, for NS16000 Series systems, see the NS16000 Series Planning
Guide. You can also find information about which networking products are supported on your
system in the NonStop Networking Overview.
CAUTION: The CIP subsystem includes a front-end device running the Linux operating system.
Do not use any Linux command that is not documented in this manual as a supported command.
Using unsupported Linux commands can cause failure of the CIP subsystem.
This chapter provides an overview of the CIP subsystem including:
• “CIP Hardware Overview” (page 27)
• “CIP NonStop Host System Software Overview” (page 28)
• “CIP CLIM Software Overview” (page 29)
• “The CIP Subsystem for Internet Protocols (IP CIP)” (page 31)
• “The CIP Subsystem for Storage I/O (Storage CIP) and the Storage Subsystem” (page 57)
• “Subsystem ID and Product Numbers” (page 59)
• “Capacity and Resource Use” (page 60)
Internet Protocol Version 6 (IPv6) Compliance
The CLIM complies with Internet Protocol version 6 (IPv6), an Internet Layer protocol for
packet-switched networks, and has passed official certification of IPv6 readiness.
CIP Hardware Overview
NOTE: Your system might require a NonStop System Console that supports DHCP and TFTP. For
more information, see the planning guide for your system.
The CLuster I/O Module (CLIM) provides the physical interface to the network or storage devices.
The CLIM includes a ServerNet PCIe card with multiple ports that interface to the ServerNet fabric
of the NonStop host system.
The CLIM is rack mounted in the NonStop system cabinet and connects to one or two X and Y-fabric
ports by means of fiber cables running from its ServerNet PICs to ServerNet ports on the NonStop
host system. The CLIM connects from its management processor interface (eth0) and its Integrated
Lights Out (iLO) interface to a maintenance switch.
