Description
The DZERO Level 3 Trigger and Data Aquisition (L3DAQ) system has been
running continuously since Spring 2002. DZERO is loacated at one of the
two interaction points in the Fermilab Tevatron Collider. The L3DAQ
moves front-end readout data from VME crates to a trigger processor
farm. It is built upon a Cisco 6509 Ethernet switch, standard PCs, and
commodity VME single board computers. We will report on operating
experience, performance, and upgrades. In particular, issues related to
hardware quality, networking and security, and an expansion of the
trigger farm will be discussed.
