Fedora ARM Shopping List

July 2011

Equipment shopping list:

• DigiKey
  • 17 PandaBoards
  • 15 power leads/barrel connectors
  • Everything on the motion sensor parts list
• Canada Computers
  • 17 8GB SD cards
• McMaster-Carr
  • 4 stainless steel threaded rods - #4-40 x 24"
  • 2 packs of 6 acorn nuts - #4-40 stainless steel
  • 1 pack of 1.25" nylon spacers

Also needed but not yet sourced:

• Network cables (recommend Tiger Direct or Canada Computers)

Questions:

1. Do we need another switch?
2. Should we use the existing ATX power supply for both stacks, or buy a separate one for the new stack?
3. What colours of cables should we use? Buy 5' again?
4. Our existing numbering scheme is running out of numbers. Should we switch to groups of 10 machines? (i.e., cdot-guru-5-{0..9}?) Or change the way we map unit numbers to IP addresses?
5. Do we need anything else? How about...
   • The UPS -- does it have capacity for the additional builders? If Australia and Ireland are carrying part of the workload, does that shelving unit need a UPS too? Which model should we order?
   • NICs? We need to replace the one we swiped from Rome, should we add a 2nd one to Ireland too? (If we move the DB somewhere, that would be the ideal spot)
   • Disks?
   • RAM?
   • Flyswatter (Jtag for PandaBoards, to help pinpoint why they crash)?
   • Backup drives?
   •  ???

Note: hex nuts, 0.25" nylon spacers, and heat-shrink tubing are left over from first PandaStack
