DETER Clusters ISI UCB
Progress (1) • People: • New ops guy (Kevin Lahey @ isi) getting up to speed • Reliability: • Daily backups for users and boss, 1-time tarballs for all other nodes • More robust Nortel switch configuration • ISI or UCB users/boss machines can run either or both clusters • Security: “Panic Switch” to disconnect from Internet
Progress (2) • Emulab Software: • Unified boot image for –com1 and –com2 machines • DNS servers, IP addresses in Database • Click image with polling • Incorporated state of Emulab as of about 9/30/05 • Debugged at UCB, then installed at ISI • Firewall and experimental nodes must be resident on the same switch • Release/update procedure is still problematic – for discussion in testbed breakout
In-Progress (1) • Reliability: • Automating fail-over between clusters (DB mirroring / reconciliation scripts) • Security: • Automatic disk wiping on a project/experiment basis • Automating leak testing for control/experiment networks • Performance: • Redoing the way emulab-in-emulab handles the control net (saves 1 experimental node interface) • Improving the performance of the VPN/IPsec links • Supporting a local tftp/frisbee server at UCB
In-Progress (2) • Federation: • Supporting running federated experiments between separately administered Emulabs using emulab-in-emulab • Netgraph module to rewrite 802.1q tags as they pass through a VPN tunnel (similar to Berkeley and ISI link) • Configuration: • Incorporating EMIST setup/visualization tools into Dashboard • New Emulab Hardware Types: • Supporting IBM BladeCenters (currently testing with 12x2 BC) • Routers as first-class objects
Network Topology • Open hypothesis: Inter-switch links may be a bottleneck • Foundry/Cisco-Nortel and Nortel-Nortel • Adding multiple 10GE interconnects • Exploring alternate node interconnection topologies • Example: connecting each node to multiple switches • Potential issue: Assign is a very complex program • There may be all sorts of gotchas lurking out there
Other New Nodes on the Horizon • Secure64 • NetFPGA2 • pc3000s with 10 interfaces • Research Accelerator for MultiProcessing (RAMP) • 1,000 200-300 Mhz FPGA-based CPUs • Some number of elements devoted to FSM traffic generators • Many 10GE I/O ports • ~$100K for 8U box at 1.5KW
