The Isilon Node Layer

The tests mapped to this layer help administrators to find out the following useful metrics:

• the current status of the nodes;
• the load balancing capability of each disk on the node;
• the throughput of network and disk drives of the node;
• the load received by the nodes through each protocol;
• the rates at which the data was transmitted and received to perform the protocol operations.
