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

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

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

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

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

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

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

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

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

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

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.
