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?
