HEP System Managers’ Meeting,RAL,1st July 2004
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
• 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
• 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
• 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
• 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
• 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
• 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?
• Default allow
• Default deny incoming
• Default deny incoming/outgoing
• Difficulties for grid/video-conferencing?
