This page describes regular PolyLab equipment. If you have questions about the setup or want to donate some gear, please contact us.

Poly-client and -server machines

We have a cluster of 30 PCs dedicated for running Polygraph tests. Each PC has:

• Intel 440BX motherboard
• 400 MHz Pentium II processor
• 128 MB PC100 SDRAM
• Intel 10/100 Ethernet interface
• 8GB IDE hard drive

All PCs are running tuned FreeBSD 3.1-RELEASE OS. The machines are able to generate at least 700 req/sec stream under DataComm-1 workload (a ``no-proxy'' experiment).

Networking gear

All switches and routers in this section are donated by or loaned from the corresponding companies.

• Cisco Catalyst 2900 (24 100Mbps port Ethernet switch)
• Five Alteon AceSwitch 110 (8 100Mbps port Ethernet switch with two 1Gbps uplinks)
• Foundry FastIron (24 100Mbps port Ethernet switch), on loan from Novell
• Two Cisco 7200 routers
• 3Com 8 port 100Mbps Ethernet hub
• Intel 4 port 100Mbps Ethernet hub

Caching proxies

We have been working with several vendors on stress testing their caches. Some vendors found it useful to leave their boxes with us for evaluation purposes and to make sure they are compatible with new versions of Polygraph. The Lab currently hosts these proxies:

• Cisco Cache Engine 2050
• Cisco Cache Engine 550
• Cobalt Networks CacheRaQ
• Novell ICS powered by Dell (ICS-130A)
• Novell ICS powered by Compaq
• Squids powered by AC

Other

Five general purpose PCs that we sometimes use for small scale tests or for running proxy software. A Digital Alpha 1200 box with a disk shelf (an equipment and research grant from DEC/Compaq).

At least 100 hand-made Ethernet cables.
