Infiniband cluster for Future DAQ
نویسندگان
چکیده
The data acquisition for future experiments at FAIR requires a fast and relatively large network farm for event data transport from front-end electronics to the computing nodes where further event analysis can be performed. The CBM experiment, for example, produces about 1 TB/s of raw data rate, which should be switched in such event building network (B-Net). This requires to build a system with ∼1000 nodes, each connected to a network with 1 GB/s link performance. Currently we are evaluating InfiniBand (IB) as probable candidate for B-Net in our first prototype of a Data Acquisition Backbone DABC (see in this report). A small test cluster of 4 nodes was installed at GSI in November 2005. Each node of that cluster is equipped with a Mellanox MHES18XT InfiniBand Host Channel Adapter (HCA). The nominal data rate of such adapters is 1GB/s in full duplex mode.
