Managing System Resources for Nodes and Queues
The type of ASIC that each line module uses determines the system resources for nodes and queues.
Line modules with the EFA ASIC hardware provide 85,000 descriptors that are shared between all nodes and queues. Each line module supports a maximum of 49,000 nodes or queues per line module.
Line modules with the FFA ASIC hardware provide 2000 level 1 nodes or queues and 64,000 level 2 nodes or queues. The ES2 4G LM provides 2000 level 1 nodes or queues and 128,000 level 2 nodes or queues. The router implicitly creates the level 2 node. Each line module supports a maximum of 64,000 nodes or queues per line module.
Line modules with the TFA ASIC hardware provide 96,000 descriptors that are shared between all nodes and queues. Each line module supports a maximum of 64,000 nodes or queues.
