Features
The SCM provides or supports the following features and functions:
Switch Fabric
• Non-blocking architecture for 40-Gbps full duplex non-blocking
aggregate throughput
• 10-Gbps full duplex throughput for each service module slot
• Switch control-plane and data-plane functions
• 9K jumbo frames
Chassis Management
• RS232/Console serial interface for local switch management
• 10/100 Management Ethernet interface for local/remote switch
management
• Mirror port for monitoring and troubleshooting user ports
• Service definition and policy enforcement
• MAC-address assignment for modules
• Real-time clock synchronization for modules
• Gathering and monitoring of module health status and statistics through
LEDs and software
• Module insertion/removal in a slot
Environmental Control and Management
The SCM also manages or monitors the following functions:
• Temperature changes in the chassis and for each module
• Module resets (for example, if a module’s temperature gets too high) or
power-down operation
• Power draw for each module
• Fan tray control interface
Dual-Channel SCM
The SCM’s dual-channel bus architecture enables it to communicate over
two separate buses to the system disk drives. This configuration provides an
additional level of redundancy by providing a second SCSI bus and permits
each SCSI drive to be connected to the SCM in slot 1. For more information
about the SCM and its bus interconnections, see Disk Drives
, on page 3-4.
