I love name bramble for the R-Pi cluster.
Im not sure if this is of any help to anyone but my plan is to create a small R-Pi cluster that will run Hadoop, Hive, HBase. So when doing work I can avoid a noisy server room.
This is a basic idea what I'm thinking.
- 8 port switch
- 7 port powered USB hub
power from each USB port on the hub wired into the 4,5,7,8 wires/pins of each Ethernet port, apart from the last two Ethernet ports which will be outside link as such, and to allow for daisy chaining them.
- mounting for R-Pi
- ethernet plug with micro-usb & ethernet wire coming off (PoE Adaptar)
- 2x LEDs (hope to connect via GPIO, power on led and network traffic)
Hopefully this is possible, as it would make wiring lots together quite a snap.
7 Port - Powered USB Hub (type 1):
7 Port - Powered USB Hub - with switch (type 2):
8 Port - 10/100 Ethernet Switch:
It be nice to know if i can network boot them, as that would be the most ideal method, have one R-Pi as master with netboot image, DHCP installed, Hadoop NameNode.
Then have a slave image that contains hadoop datanode, hive etc.. installed.
This would make adding a new node to the cluster as simple as use PoE adapter and connect to the network via one of the Power/Ethernet boxes.
