Servers

• a users, file, and serial line server (ops.schooner.wail.wisc.edu), consisting of:
  • Dual 500MHz Intel Pentium III processors
  • Intel L440GX+ motherboard (the GX+ chipset)
  • 512MB PC100 ECC SDRAM

  • 512MB PC133 ECC SDRAM
  • Dual-Channel On-board RAID (5) Controller 128MB Cache (2-Int Channels)
  • Five 18GB Ultra3 (Ultra160) SCSI 10K RPM Hot Plug Hard Drives
  • Dual Redundant 330 Watt Power Supplies
  • Integrated Broadcom Gigabit BaseT and Intel Pro/100+ NICs

• a motley collection of serial line servers, consisting of:
  • a 2U home brew box (our old "ops" node) with 3 64-port Cyclades-Ze PCI Multiport Serial Boards (model number SEZ0050).
  • 1U box from ASA Computers with another 64-port Cyclades-Ze PCI Multiport Serial Board.
  • 2 Dell OptiPlex GX240s with a total of 6 32-port RocketPort Universal PCI interfaces.
  • a serial line server for critical Emulab machines, consisting of an ISP1100 box, like the "pc850" nodes above with a 4-port Cyclades card.

Switches and Routers

• 7 Cisco 6500 series high-end switches. Five serve as the testbed backplane ("programmable patch panel").
  The other two, a 6506 and 6509 providing "control" interfaces for the test nodes with the 6509 hosting an MSFC router card and functioning as the core router for the testbed, regulating access to the testbed servers and the outside world.
  

Power Controllers

• 10 APC MasterSwitch AP9210 8 port power controllers.
  (The AP9210 is discontinued; replaced in the product line by the AP9211.)

• 7 BayTech RPC27 20-port remote power controllers.
  

• 24 BayTech RPC14 1U 8-port remote power controllers.
  

Racks

• 13 Wrightline "Tech I" racks: 44U, 34" deep, 2 are 24" wide with cable management; the rest are 19" wide. (Aug 2001: these appear to have been discontinued or renamed.)

Layout

Four ethernet ports on each PC node are connected to the testbed backplane. All of the over 1300 ports can be connected in arbitrary ways by setting up VLANs on the switches via remote configuration tools. The current PC and switch topology is shown here.

The fifth ethernet port on each PC is connected to the core router. Thus each PC has a full duplex 100Mbps connection to the servers. These connections are for dumping data off of the nodes and such, without interfering with the experimental interfaces. The only impact on the node is processor and disk use, and bandwidth on the PCI bus.
