Versatile I/O (VIO) Enclosure
A VIO enclosure, which is 4U, provides Gigabit Ethernet networking and connectivity to the
processors. Two VIO enclosures, one required for each ServerNet fabric, are installed in a 19-inch
rack.
For a description and illustration of the VIO enclosure slot locations, see Figure 3 (page 40).
Each VIO enclosure contains:
• Connectivity for up to four processors, configured in pairs
• Connectivity for up to four Storage CLuster I/O Modules (CLIMs) configured in pairs and used
to communicate with storage devices such as Serial Attached SCSI (SAS) disk enclosures or
Enterprise Storage System (ESS) disks
• Up to eight copper/optical Ethernet ports used for Ethernet connectivity. Additional Ethernet
connectivity is available via IP or Telco CLIM connections with up to two IP or Telco CLIMs.
NOTE: For details about how to connect to the embedded or optional expanded Ethernet
ports on the VIO enclosure, ask your HP service provider to refer to the Versatile I/O Manual.
• Two fans to provide the cooling for components inside a VIO enclosure
• Two power supplies with universal AC input to provide power to the components in a VIO
enclosure
CLuster I/O Modules (CLIMs)
CLIMs are rack-mounted servers that can function as a ServerNet Ethernet or I/O adapters.
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.
NOTE: All CLIMs use the Cluster I/O Protocols (CIP) subsystem. For more information about the
CIP subsystem, see the Cluster I/O Protocols (CIP) Configuration and Management Manual.
Two models of base servers are used for CLIMs. You can determine a CLIM's model by looking at
the label on the back of the unit (behind the cable arm). This label refers to the number as a “PID,”
but it is not the PID of the CLIM. It is the “Number on Label” in Table 1 (page 22) below. The same
number is listed as the part number in OSM. Below is the mapping for CLIM models and earliest
supported RVUs:
