The purpose of this proposal is to describe highend computing, storage, networking and grid computing grid infrastructures in UNAM, and how high energy and particle physics research groups have promoted and used them. National University of Mexico (UNAM) has a long tradition in High Performance Computing. Since 1991, both centralized and group efforts have been conducted to provide high performance computers for several areas of research. For the last five years, the main supercomputer at UNAM has been KanBalam, which is a 342-node cluster with 130 TBytes storage and a performance of 7.13 TFlop/s. In a few months, UNAM will update its general-purpose supercomputing infrastructure with a new 100 TFlop/s. cluster. Staff for centralized supercomputing services has maintained close collaborations with high energy and particle physics Mexican communities, including HAWC, Auger and ALICE groups. Several projects and activities are the result of these collaborations, including the Latin American grid projects EELA-1, EELA-2 and GISELA. Since last year, UNAM is deploying infrastructure and human resources to become a T1 node of the ALICE-Grid.
