  3. Outline • The last year • Things we did and stuff we bought • Where we are now • The next year • What is coming up • Some non *nix stuff

  4. Over the last year • Performance • Hardware • Other stuff • Issues

  5. Performance • 1,382,736 jobs in year to 2009-05-31 • Cluster has been underutilised much of the time • Availability 93% over last 6 months • Lower than we had hoped • But not entirely our fault!

  6. Jobs Run

  7. Hardware • Most purchasing was for GridPP • 70 new SuperMicro twins (1120 cpu cores)‏ • 25 new 20TB Viglen storage nodes (about 450TB of usable space)‏ • Assorted new hardware for service nodes, etc. • Not all new kit is yet fully commissioned

  8. Other Stuff • Tested SL5 WN • Logging with rsyslog (to 2 hosts)‏ • Setting up machines and services for assorted projects • Desktop Linux • Talked to users • One test (SL5) box set up

  9. Issues • Air conditioning • Several failures, including twice in one week after Xmas • Site power • Big power cut • Planned work (on short notice) • The Sun • Building Management System • R89 delays and movement schedules

  10. Where We Are Now • ~613 TB Storage • dCache version 1.9.1-7 • 1584 CPU cores • 2740 kSI2k • Ahead of 2009 GridPP pledges

  11. The next year • Consolidate storage in R1, CPU in lab R27 • Replacing RGMA and BDII hosts with virtual machines • Local private network for IPMI, RAID, APC, etc. • New machines to host VO software. • An SL5 CE • Getting ready to move to all SL5 some time. • CREAM for added yumminess. • Desktop Linux (again!)‏ • LHC data? • Networking...

  12. Networking: now • Nortel 55xx stack in R1 • Similar switches installed in R27 but not yet stacked • Interconnected through RAL site networking • 2 * 1GB links to R27 • 1 * 10GB to R1

  13. Networking: planned • Establish stack in R27 • Connect machine rooms with direct 10GB fibre link • Hopefully add second 10GB link later

  14. Not just *nix… • Windows • Macs • Other services

  15. Windows • Moving to Windows 2008 domain (as I speak!) • Recent desktop machines running Vista Business • VMs for some legacy software • Laptops running Vista Ultimate with Bitlocker encryption (older laptops encrypted with Pointsec) • Remote reporting/updating to our own WSUS (Windows Updates) service and Sophos Enterprise server

  16. Mac • An increasing number of Apple computers in the department • Support still not “official” but provided on a best efforts basis • Sophos antivirus • if you want to heckle this, wait for next year when we announce this for Linux! • Pointsec encryption

  17. Some General Stuff • Visitors’ network • Authenticated wireless access coming up... • Promoting the use of WebDAV for remote file access, rather than PPTP (CERN already use this)

  18. So… • We have the technology… • We’re doing pretty well, but are underutilised • Now we need to work on • Reliability • Getting everything commissioned promptly • Improving our infrastructure
