Abstract :
The paper first reviews the main achievements obtained by the Romanian LCG Federation (RO-LCG) since its founding, emphasizing its recent performances within the WLCG collaboration and also discussing the current limitations of the network infrastructure. Then the presentation focuses on the technical organization of the DFCTI´s main Grid site, RO-07-NIPNE, and on the requirements it must satisfy in order to ensure the quality and reliability necessary for WAN communication with the Tier-1 centers, and for efficient data handling within the LAN. The design of a scalable Storage Elements optimized for ATLAS analysis is proposed. Also, the maximization of the throughput of the disk write on worker nodes by using congestion control algorithms is investigated.
