  • Backup to tape autoloader (ADIC Scalar24 with SDLT).
unix services
UNIX services
  • Currently RedHat 7.3
  • File servers and Web server (also CVS server)
  • Needs hardware and software upgrades…
    • Possibly move to rack mounted systems
    • Scientific Linux ?
  • LINUX on desktop
    • Currently not encouraged, self-managed.
    • RAL looking at central rpm repository used with yum
      • Possibility of standard PPD configuration, with yum for updates, and yumit monitoring.
      • Looking to ‘discourage a bit less’
tier2
Tier2
  • Currently offering to LCG:
    • 21 dual-CPUs (mix of 1.4GHz PIII and 2.4GHz Xeon, (along with 8 infrastructure nodes)
    • 500GB disk
  • Just (about) delivered:
    • 24 dual 2.8 Xeon
    • 4TB disk
  • Plan future expansion in racks
    • Looking at space / power / cooling in computer room.
networking and vms
Networking and VMS
  • Gigabit fibre to router – possibly adding second gigabit link for Grid.
  • Gigabit switch central to networking. 10/100 to ports in offices
  • Gigabit over copper in server room.
  • Possibility of separate link from site router for GRID.
  • VMS expected to be turned off soon now…….
    • Financial information for budget holders being provided in another way.
security
Security
  • May 2004: Possibly a CVS exploit. System re-installed anyway.
  • Nov 2003: Did have a scare on Windows server when user directories vanished. Believe it was a false alarm, and really caused by a program running awry.
  • Scanning:
    • Lab scanning from ‘outside’ firewall
    • Microsoft HFNetChk – Windows patches
    • Nessus learning to identify false positives.
  • Just starting to look at running some spyware detection.
