Simple USB3 + Power connectors for making computing grid or clusters

This board is perfect for making a computing cluster or grid and USB 3 seems to be the best interconnect method (Fast Ethernet is too slow).

What is the simplest and cheapest way of attaching a USB 3 and power cable?

Can you manufacture an edge connector/adaptor for the board with these cables?

Can you manufacture a base board that lets you connect 8 or 16 or 32 or 64 of these with USB 3 sockets and power?

Having one of these options would be perfect.

Hi
The LeMaker Guitar Base Board Rev.B is designed with the USB3.0 Mirco-B interface. Therefore, in order to connect to the USB3.0 HDD, you need to choose a USB3.0 OTG cable. For more information, please refer to the wiki tutorial at http://wiki.lemaker.org/LeMaker_Guitar:USB3.0 .
We are designing the base board Rev.D which can support four pieces the lemaker Guitar, and integrated 1000M switch chip, USB3.0 to 1000M chip. Meanwhile, you can extend your cluster based on  more base board Rev.D through the 1000M ethernet port. We will produce the project board in next month.
Thanks for your support.

Can you please elaborate a bit on that or better add the specs immediately here: http://wiki.lemaker.org/LeMaker_ ... ar_base_board_Rev.D

If I understood right you plan something like a cluster baseboard, providing 4 SO-DIMM sockets to insert coreboards into ? On this baseboard each coreboard is provided with an USB to GBit Ethernet chip and all 4 Ethernet ports are internally connected to a switch IC that has at least a fifth port available as external Ethernet jack? Correct?

a) which USB-to-Ethernet adapter do you plan to use?

b) which Ethernet switch do you plan to use?

c) Given the switch IC has more than 5 internal ports how many Ethernet jacks will the baseboard provide?

d) What about Ethernet throughput? Using an USB adapter is known to cause bad performance and many IRQs. Does the adapter chip you plan to use supports jumbo frames? What about Ethernet throughput with jumbo frames enabled?

e) What about the power consumption and PSU options of the whole setup? I managed to get close to 8 W when testing coreboard + baseboard version B therefore 12V/2A won't be enough.

f) What about storage options for the individual coreboards? If you don't implement an internal USB hub for each coreboard and use the one USB3 connection for Ethernet then all that's left is USB 2.0. Will one or both USB 2.0 connections be available per coreboard? In which form? Type A?

g) Did you thought about implementing one coreboard as 'master node' which an internal USB hub, a JMicron JMS567 USB3-to-SATA bridge and either a SATA or mSATA connector?

h) What about the price of this baseboard variant?

The whole idea to build a cluster from components that lack suitable interconnects seems a bit strange but if the price will be attractive and storage performance doesn't matter...
