HEP System Managers’ Meeting,

RAL,1st July 2004

farm hardware
Farm hardware
  • Alice Farm: 18 dual 800 MHz PC boxes
  • BaBar Farm: 40 dual 800 MHz blades
  • Atlas Farm: 38 dual 2.0 GHz blades
  • Upgrades to Atlas Farm ?
  • Currently housed in room with 25kW of cooling
farm systems
Farm systems
  • Alice and Atlas farms running RedHat 7.3
  • BaBar farm running RedHat 7.2
  • Issue of maintenance of BaBar farms and upgrades of BaBar software
  • Atlas farm split into local part and LCG-2 part at present
desktops
Desktops
  • Around 40 user-desktop PCs plus around 12 PCs in various labs/rooms
  • All but 2 user-desktops running RedHat 9
  • 2 user-desktops running Windows XP
  • The other PCs running Linux or Windows as required
laptops
Laptops
  • 9 laptops in a group Pool
  • Half-a-dozen user laptops (mainly students)
  • All laptops are behind an extra level of ‘firewall’ to the outside world
servers
Servers
  • Mixture of old and new general purpose Linux servers, with RedHat 9 and newer systems to be trialled (Fedora 2, and RHEL clones)
  • Citrix Windows Terminal Server(s) for those required MS applications.
admin
Admin
  • All Linux systems centrally administered (by me)
  • Windows systems dual-admin’d with owner
  • User laptops self-admin’d (hence the extra mostly-deny ‘firewall’)
networking
Networking
  • Gigabit to the newer servers, 100Mb/s to desktop (but gig interfaces on our new PCs)
  • 2 Gbits/s for the dept to rest of campus
  • Campus firewall expected to adopt default-deny policy
  • But - no extra I.S. personnel and history of delayed response to problems because of under-manning
question site firewall policy at other sites
Question – site firewall policy at other sites?
  • Default allow
  • Default deny incoming
  • Default deny incoming/outgoing
  • Difficulties for grid/video-conferencing?
