  1. Lawrie Lowe: System Manager Yves Coppens: SouthGrid support HEP System Managers’ Meeting, RAL, May 2007 Birmingham site report

  2. Desktops • 60 user-desktop PCs running Linux • Older user-desktops are Pentium 3.2 GHz, 1-GByte RAM, running Scientific Linux 3. • Newer desktops are Athlon X2 dual-core, 2-GByte RAM, running Scientific Linux 4. • Migrating all to SL4 on user request • 4 user-desktops running Windows XP • 12 PCs in labs running whatever experiment requires: Windows or Linux

  3. Farm hardware • Alice Farm: 18 dual 800 MHz PC boxes • BaBar Farm: 120 dual 800 MHz blades • Atlas Farm: 38 dual 2.0 GHz blades • 50% of Atlas Farm and 4% of BaBar Farm is for our local use on SL3 • 50% Atlas and 90% BaBar farm on grid • 6% of BaBar farm running a Pre-Production Service (PPS)

  4. Laptops • 14 laptops in a group Pool, running Windows XP and SL3/4 dual-boot • ~10 user laptops (mainly students) • All laptops are behind an extra level of ‘firewall’ to the outside world

  5. Servers • Linux servers running various systems: SL3, SL4, SL4_64, and CentOS 5 / SL5. • Most recent file-server running CentOS 5, with 16 TB raid, split as 2 filesystems. • Citrix Windows Terminal Server(s) for those required MS applications.

  6. Networking • Gigabit to the newer servers, 100Mb/s to desktop (but gig interfaces on most PCs) • 2 Gbits/s for the dept to rest of campus • Campus firewall adopting default-deny policy, but Physics has its own firewall • Connection on campus to UKLight, in testing by campus staff

  7. Grid • UK Front-ends hosting CE, MON and SE plus CEs for BaBar farm and PPS service • Storage increased to 10 TB earlier this year • All nodes run on SL305, gLite 3 update 24 • pxe-boot/kickstart installation using yum and yaim • + some steps to finish off configuration

  8. On-Campus clusters • Existing eScience cluster with a batch system of 38 dual nodes (nearly 3 yr old) • New BEAR cluster installing this week (May 2007): initial phase 256 nodes, each with two dual-core processors, 60 TB data. • By final phase: 2048 cores, 100 TB data. • A share for us; plan for gridPP too.
