The Sun Blade 8000 Series offers various methods for managing chassis components and Sun Blade Server Modules (blades). All system management access is through a management port on the Chassis Monitoring Module (CMM). Internally, each CMM contains an Ethernet switch forming an internal Ethernet network. This internal Ethernet network connects the CMM, blade service processors (SP), and external Ethernet ports to enable full system management across an Ethernet LAN.
Installing a second CMM provides redundant system management access. Should network communication on one management port be lost, the management port on the redundant CMM will become active. Internally, the management network is also redundant. Each Chassis Monitoring Module and blade SP is connected to both the primary and backup networks. As depicted in the following schematic, if one network is unavailable, the other network is used, providing a protected environment.
