Topic: Middleware_transition
All nodes running SL5, exceptfollowing nodes:
- lcgCE 3.1 (condor)
- SE (DPM)
running SL4
Upgrading
SE under progress. the lcgCE would stay longer I imagine.

ARGUS/glexec
Not yet installed
BDII_site
gLite 3.2
CE (CREAM/LCG)
1 LCG CE (condor)
1 CREAM CE (torque)

Comments
Topic: Protected_Site_networking
- Gigabit backbone with 1Gbps connection onto the University network shared with Group Systems
- Two HP HP E2910-48G al Switches.
- All the WNs are on the gigabit-network
- Dual 10Gbps University connections on to JANET
- GRID systems on same public subnet (/24) as Group Systems.
- Gradual rearrangement of Group IP addresses to put Group and GRID systems in separate halves of this subnet – nearly completed (2 critical servers left to move).
- Monitoring – use MRTG for traffic history.
Topic: Resiliency_and_Disaster_Planning
- This section intentionally left blank
Topic: SL4_Survey_August_2011
We have following nodes running SL4
- lcgCE 3.1 (condor)
- SE (DPM)
- 7 x disk-servers
Upgrading SE and the disk-serves currently under progress. the lcgCE would stay longer I imagine.

SRM
Current status (19/11/2009): Presently at 1.6.11 ob gLite 3.1 (glite-SE_dpm_mysql-3.1.10-0.x86_64)
Planned upgrade: Already tried several times but error returned reporting:
Error: Missing Dependency: libapr-0.so.0()(64bit) is needed by package apr-util
Error: Missing Dependency: libapr-0.so.0()(64bit) is needed by package httpd
Comments: There is already a opened ticket for that: #52552
