Symptoms

There were 2 nodes of a 7420 connected to an exadata over 10 Gbe network interfaces for RMAN backups. 

When running 'dd' commands from the exadata to each head, it was discovered that one head performs 2x as well as the other. 

We will call the heads 'T' and 'U'.  the 'T' head performed at 1/2 the performance of the 'U' head

  

Changes

A certain analytic was enabled as described in the cause section.
