Overview
V-Class System Components
monitoring the server hardware, as well as diagnostics operations. You
also must use the Service Support Processor when installing or
upgrading V-Class firmware.
The Service Support Processor runs HP-UX V10.20. In addition to HP-
UX software, the Service Support Processor includes files and utility
software for managing and monitoring the V2500/V2600 server. These
items and all other V2500/V2600-related files, including log files, that
are stored on the Service Support Processor can be found in the directory
/spp.
The default user account for Service Support Processor operations is
sppuser, with a home directory of /users/sppuser.
NOTE The abbreviation “spp” stands for “scalable parallel processor” and is not
to be confused with “SSP”.
See Chapter 3 for more detailed information on the Service Support
Processor.
Server Console and Diagnostic Connections
The V2500/V2600 server’s utilities board provides connections from the
Service Support Processor to a V2500/V2600 server’s cabinet or cabinets.
Both the console port and diagnostic LAN on each cabinet are connected
to the Service Support Processor for system monitoring, booting, and
other operations.
The Service Support Processor connections to a V2500/V2600 server
provide only console, diagnostics, and preliminary booting support. For
multiple-cabinet servers, the CTI cables between cabinets provide the
multiple-cabinet interconnections that create a single, unified V2500/
V2600 HP-UX system. Cross-cabinet connections are covered in the
section “Multiple-Cabinet Server Connections” on page 15.
A single-cabinet V2500/V2600 server is connected directly to the Service
Support Processor, as shown in Figure 6 on page 7.
As shown in Figure 5, multiple-cabinet V2500/V2600 servers have
connections from each cabinet’s utilities board to either the Service
Support Processor or a terminal server.
While a four-cabinet V2500/V2600 server configuration is shown in
Figure 5, a two-cabinet or three-cabinet configuration involves the same
type of set up among the Service Support Processor, V2500/V2600
cabinets, and the terminal server.
