Abstract :
PHENIX is one of two large experiments at Brookhaven National Laboratory´s Relativistic Heavy Ion Collider (RHIC). At the time of this conference, the Run 10 of RHIC is in progress and has generated about a PetaByte of raw data. The following summer shutdown marks the begin of the installation of the PHENIX upgrade detectors, the first of which will be commissioned for the upcoming Run 11. In order to accommodate the new detectors in the PHENIX data acquisition, we will start to implement significant changes to the system, such as the switch to a new generation of readout electronics, and the move to 10 Gigabit Ethernet for the components with the highest data volume. Once fully installed, the new detectors will about triple the current maximum data rate from about 600MB/s to 1.8 GB/s.
