Embedded Apex Software

All Paceline intelligent switches feature embedded Apex Software, which 
makes InfiniBand fabrics easy to install, operate and maintain. Apex 
Software features:

    * Trunk load balancing optimizes performance on parallel paths
    * Resilient topology control automatically reroutes traffic around 
fabric element failures
    * Independently enabled, full-function InfiniBand subnet manager with 
hot standby function
    * Powerful performance statistics and analysis tools
    * Familiar CLI, SNMP and web management interfaces simplify fabric 
    * Full Integration support for BMC Patrol, IBM Tivoli and H/P OpenView 
management applications

The Paceline 4100 is designed to deliver high performance in demanding 
enterprise and high performance computing applications. Based on the IBM 
InfiniBlue 4x switch chip, the 4100 delivers traffic independent, 
non-blocking throughput and line rate forwarding on all ports, 
The Paceline 4100 supports any network topology, from partial or full 
meshed network designs to multi-level hierarchal designs, ring designs, or 
re-arrangeably non-blocking Clos network designs.
A comprehensive set of management interfaces and tools enable the 4100 to 
seamlessly integrate into existing enterprise management frameworks. The 
4100 can be managed through a Command Line Interface (CLI), embedded web 
server, a standard SNMP interface, and a front panel LCD display and 
keypad. It can also be managed through popular enterprise management 
systems, including H/P OpenView, IBM Tivoli and BMC Patrol. The LCD 
display and keypad provide a convenient facility to enter configuration 
parameters, monitor device level attributes, and display critical events.
