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?
   •  ???

Suggestions:

1. Fast Ethernet/ Gigabit switch for new pandas .There is not enough room/ 17ports in existing ones.
2. Power Supply: we have the power connectors (but will have to cut them from unused connectors) for power supply. We have capacity in existing supply for new hardware.
3. UPS: In terms of free sockets on unit and enough power backup, we have it(battery backed up/4 and surged protected only/2) but good to have new one.
4. We also have to make room for new network switch on rack and will have to move some builders.
5. Good to have more removable drives (for backups ). We have 2 for now and each is being used almost 20% but mnt/koji is also growing too fast.
6. Good to have USB3 support on Hongkong.
7. 10 additional SD cards to replace old ones.

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