This chapter includes the following sections:
The Netra CT server software can be categorized as follows:
The software is described in TABLE 1-1 and represented logically, with the hardware, in FIGURE 1-1.
MCNet is a communication channel over the cPCI midplane. It can be used to communicate between the alarm card, the host CPU board, and any MCNet-capable satellite CPU boards for exchanging system management information.
Note - The Netra High Availability (HA) Suite may be used to provide enhanced services for customer high-availability applications. It is required to use certain monitoring capabilities of the MOH application, such as monitoring nfs and tftp daemons. When installed, the software runs on the host and satellite CPU boards. The Netra HA Suite is ordered and shipped separately from the Netra CT server.
In the Netra CT server, the alarm card manages most of the components connected to the midplane. The host CPU board accepts and owns peripherals, such as I/O boards or disks; it runs user applications and distributes tasks within a system. In a Netra CT server, each CPU board (including satellite and host CPU boards) runs its own copy of the Solaris OS, and each is therefore considered a server; the alarm card, plus the CPU boards and the other system FRUs, make up a system. There can be several systems in one chassis.
The Netra CT server accepts the Netra CP2140 or the Netra CP2500 as the host CPU board.
The hardware interfaces include the Intelligent Platform Management Interface (IPMI), the CompactPCI (cPCI) bus, and the PCI interface (PCI i/f) on the alarm card, host CPU boards, and satellite CPU boards.
Netra CT server system administration typically includes installation, configuration, and administration tasks.
Solaris administration on the Netra CT server, including adding Solaris user accounts, is performed by logging into the host or satellite CPU board. Netra CT server administration is performed by logging into the alarm card and using the alarm card command-line interface. The alarm card can be used as the single point of entry in the Netra CT system for configuration and administration purposes.
System administration tasks are described in the following chapters.
