Why do you think you need to build such a device? Why don't you buy
it?

Colocation requires rack servers, but thanks for thinking about it.
Some important things:
- what is the purpose of this collection of clients, servers,
networks and software?
- who will judge, and how will they judge, the effectiveness of it?
How fast/correctly it performs not just reliability
- what is their budget?
- how much time will they give you?
- how will you spend your time?
- how will you prove to yourself that you have finished? How can you
prove to your users/customer that it works?
I feel the general takehome from this conversation and Nick Holland's
suggestions, is that really anything might break and everything needs to
be set up to handle that.
So like, all of
* data integrity verifications,
* checksumming of everything,
* automated routines to take a node out of use in case of IO slowdown
or failure, or any other error, and
* live syncing of important stuff to another datacenter for the case o
power failures
need to be in place for there to be any real data integrity + QoS
guarantees.
Thanks!
