  1. Birmingham site reportLawrie Lowe HEP System Managers’ Meeting, RAL,1st July 2004

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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.

  7. 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’)

  8. 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

  9. Question – site firewall policy at other sites? • Default allow • Default deny incoming • Default deny incoming/outgoing • Difficulties for grid/video-conferencing?
