HEPiX – Fall, 2005
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 Unixbased 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.
