gLite3.1/SL4
I have the following services on glite 3.1
-> CEs dgc-grid-40, and dgc-grid-44
Soon to be replace by CreamCEs
-> CE dgc-grid-35
it should be decommissioned by the end of the year
-> BDII
to be upgraded in the next few months
-> SE dgc-grid-50
it has only 2% of the data at the site. I'm planning an upgrade for the
3rd week of December. Most of the data at Brunel is in dc2-grid-64,
glite 3.2 SE.

ARGUS
. EMI Argus server running stable since May.
BDII_site
. Upgrading to glite 3.2 in October
CE (CREAM/LCG)
. dgc-grid-43 running on EMI CreamCE.
. Other CEs on LCG, but to be upgraded before the end of the year
glexec
. Deployed in dgc-grid-43
. To be deployed in all CEs when they are upgraded
SE
. Main SE (95%) of the storage running on SL5 DPM 1.8
. Remaining SE will be upgraded in December
