  1. Jefferson LabSite Report Kelvin Edwards Thomas Jefferson National Accelerator Facility HEPiX – Fall, 2005

  2. Networking • WAN Upgrade • Upgrading to 10Gb MAN with connectivity to ESNet and NLR • Wireless • Implementing secure wireless using WPA • Working with Windows XP SP2, RHEL3/4, MAC OS-X • WLSE installed for management and to detect rogue access points • Looking at AirDefense for better rogue access point detection and IDS • VLans • Provides functional vs. physical network segmentation

  3. Central Computing • Email • Installed and configured a secure email server • Upgraded our SMTP email hardware for better performance and failover • Examining Solaris 10 zones • Lightweight services placed onto a single machine which appears as two

  4. Central Computing (2) • RedHat EL3 and EL4 • EL4 used for newer servers • EL3 used for desktops and farm nodes • RedHat Network Satellite • Currently at version 3.7 • Upgrading to version 4.0 • Provisioning support • Solaris patch support

  5. Central Computing (3) • Windows builds • New builds get Windows XP SP2 installed • Evaluating the use of Folder Redirection for storing desktop files onto a central server (MyDocuments, etc) • Symantec Client Security • Upgraded from Symantec AntiVirus Corporate Edition • Includes malware detection and removal • Includes firewall, but we’ve disabled • All of this is manageable via a central console

  6. File Server Storage • Installed a 25TB Panasas system • Working to resolve a few minor issues • Memory problem with automount of DF client • Access time was a big issue for us • Finally resolved with version 2.3.1 and pan_atime client • Installed 2 StorageTek B280 systems (30TB) • Fiber Channel disks and controllers • Using these for NFS file service • Very reliable and stable

  7. File Server Storage (2) • Evaluated StorageTek Flexline B680 system • Similar to B280, but uses SATA drives • Not yet ready for production • Looking for an inexpensive, low maintenance Unix-based solution for NFS with reasonable throughput

  8. JASMine Upgrade • Centralized intelligent dispatcher installed • Increases throughput • Small file bundling • Reduces load on the database • File size limit increased from 2GB to 20GB • Supports tape reuse • Copying/compressing data from 60GB 9940A to 200GB 9940B drives • 5000 tapes to be reused at $80/tape

  9. JASMine and Auger interaction • Auger is JLab’s batch farm management system • Tightly integrated with JASMine • Share/reference a common MySQL database • Smart data staging for farm jobs

  10. Grid Developments • PPDG Storage Resource Manager developers meeting at JLab in Sept • revisit SRM requirements document • JLab has SRMv2 service, SRMv3 prototype

  11. Infrastructure • Power/Cooling issues • Problems with current Generator/UPS systems • Hot Aisle/Cold Aisle philosophy for new computer room • Location of Air Conditioning thermostats

  12. Infrastructure (2) • SiteView software • Provides an ability to drill down to see Air Conditioning and UPS status in near real-time. • Provides alarms if values exceed set thresholds • Viewable from web, on and off site.
