AFS@LNFAFS@LNF

• AFS is in use in LNF since 1996 using the national wide cell infn.it

• In 1999 born the lnf.infn.it cell with 2 IBM H50 running AIX 4.3.3 and AFS Transarc

• Today lnf.infn.it cell is based on a EMC2 SAN (CX500+CX300) and 7 file server running OpenAFS

• AFS/K5 cross authentication is supported towards infn.it, le.infn.it and ba.infn.it realms

• About 15 TBytes are served to about 1200 users

• AFS is used for users's homedir, software repository, experimental data, web pages for www.lnf.infn.it, www.infn.it and www.ac.infn.it web-sites
