The tech assess call for 2/20 is cancelled since it turns out to be a
national
holiday. I don't know how many people will be home that day, but it
sure
includes me.
On another note, I have a proposal for the order of readout of the
CCDs on
each raft that minimizes the time required for the crosstalk
calculation.
I have another plan for multiplexing the 25 fibers (and telemetry
line) that
go into the IB switch on the mountain into the 10 nodes that drive the
data down to the base. The design will automatically and transparently
recover from the failure of any 1 of the 10 nodes on the mountain. No
one
node is now a single point of failure.
The addition of a second IB switch on the mountain eliminates that as
a single point of failure. This is probably as far upstream we can do to
add redundancy and insure no data is lost except for a fiber cut
connecting
the mountain to the base.
I will write this up and send it out to the team during the week of
2/20.
