As part of the observatory project to upgrade the correlator, an assessment has been requested to different groups in the observatory that are affected or that they would need to provide improvements to their products in order to be compatible with the proposed upgrades. In particular ACS will analyze the existing infrastructure and software to allow bulk data transfer to satisfy a higher throughput than what is currently needed and what efforts would be required to go beyond the current capabilities.
The existing infrastructure consists of 10 Gbps equipment including, Ethernet cards, switches and cables. In specific cases, the connection between some servers is handled by Cisco's fabric interconnect which has a throughput capacity of 10+ Gbps.
An empirical analysis was performed over the network using three approaches focused on see the current performance of our existing implementation of the bulk data transfer system.
