  The Advanced GAmma Tracking Array (AGATA) multi detector spectrometer will
provide precise information for the study of the properties of the exotic
nuclear matter (very unbalanced proton (Z) and neutron (N) numbers) along
proton- and neutron- drip lines and of super-heavy nuclei. This is done using
the latest technology of particle accelerators. The AGATA spectrometer consists
of 180 high purity Germanium detectors. Each detector is segmented into 38
segments. The very harsh project requirements are to measure gamma ray energies
with very high resolution (< 1x 10 -3) at a high detector counting rate (50
Kevents / sec / crystal). This results in a very high data transfer rate per
crystal (5 to 8 Gbps). The 38 segments are sampled @ 100 MHz with 14 bits of
resolution. The samples are continuously transferred to the CAP module which
reduces the data rate from 64 Gbps to 5 Gbps. The CAP module also adds
continuous monitoring data which results in total outgoing data rate of 10
Gbps. The STARE module is designed to fit between the CAP module and the
computer farm. It will package the data from the CAP module and transmit it to
the server farm using a 10 Gbps UDP connection with a delivery insurance
mechanism implemented to ensure that all data is transferred.
