Topic: Middleware_transition


I have a SL4 WMS (wms02.grid.hep.ph.ic.ac.uk) as there is no SL5 WMS in glite.
I use wms01 to test the EMI WMS, but it took today's (9/8/11) update to get it working. I intend to keep the glite 3.2 WMS around for a while longer until the EMI version is stable.
Note that our lcg-CEs are running SL5 (technically CentOS 5).

gLite3.2/EMI


ARGUS: none so far

BDII_site: glite 3.2

CE (CREAM/LCG): CREAM glite 3.2, no SGE support in EMI so far, lcg-CE 3.1 on CentOS 5

glexec: not so far

SE: dCache 1.9.12-8 (updates directly from dCache)

UI: glite 3.2

WMS: glite 3.1 and EMI

WN: glite 3.2

Topic: Protected_Site_networking


7th June ops meeting: Reasonably defined subnet, reasonably defined monitoring. Some firewall trickier means cacti plots aren't 100% accurate.
