Conclusions

Status Reports on Tier 1 in Korea14/14CERN-Korea Committee Meeting Conclusions ■A lot of efforts has been put to make a secure plan for network upgrade to 10Gbps by Korean government. It will be completed by March ■KISTI Tier 1 has been running stable and fully functional, fulfilling the requirements for Tier 1. ■KISTI Tier 1 will prepare for receiving 10% of produced data from ALICE during RUN2, roughly 1PB per year. ■Excellent teamwork among KCMS, CERN-CMS and KISTI speeded up the fast implementation of new CMS T3 at KISTI. It is the evidence of our fruitful future collaborations.
