Description
Summary of the Remote Labs West Lab PC Build.
Cubic Heavy Open Number Center, or C*H*O*N*C, is available for remote work. It's best equipped for DVB-S2/X experimentation, verification, and validation.

Here's
all
the
colorful
leds
blinking
away.
We
can
program
these
to
do
a
variety
of
things.
They
can
simply
be
decorations
or
they
can
track
a
wide
variety
of
things
going
on
in
the
computer.
All
these
lights
are
visible
because
the
case
has
glass
sides.
Here's
the
back
with
some
of
the
cable
routing.
This
is
before
the
glass
doors
went
back
on
chunk
has
all
the
usual
I
o,
and
you
can
see
a
lot
of
it
here
in
this
image.
We
plan
to
put
the
dvb
s2x,
modulator
and
demodulator
cards
in
here.
B
There
probably
will
not
be
a
lot
else
hooked
up
to
chunk
through
the
traditional
ports.
After
memory
tests
and
other
checks,
we
installed
unraid
what
is
unraid
it's
an
operating
system
built
based
on
linux,
for
storing
and
managing
data.
You
can
freely
mix
and
match
drives
of
different
sizes
and
speeds.
We
install
applications
within
a
container
system
and
manage
application
access
to
the
network
and
data,
we're
going
to
run
virtual
machines
from
unraid,
allowing
us
to
set
up
different
machines
for
different
tasks.
B
Unraid
is
efficient
fast
and
allows
virtual
applications
to
be
dedicated
to
physical
hardware.
Unraid
is
common
in
the
gaming
community.
It
lets
you
maximize
your
computer
system
to
be
a
high-end
gaming,
computer
and
a
home
pc.
At
the
same
time,
here's
paul
describing
some
of
the
challenges
with
unraid
setup.
A
Unraid
is
a
software
layer
that
installs
on
standard
pc
hardware
and
hosts
virtual
machines,
which
might
be
windows
or
linux
or
whatever
and
docker
containers
and
manages
the
disk
drives
the
same
sort
of
way.
A
network-attached
storage
device
would
do
at
one
level.
Unraid
is
just
a
customized
installation
of
linux,
but
it's
also
a
high
performance
hardware,
assisted
hypervisor
that
achieves
performance
nearly
as
good
as
the
bare
metal.
A
A
If
you
fully
embrace
unraid
you'll,
set
up
each
job
in
a
separate,
vm
or
container
optimized
for
the
needs
of
that
job.
The
various
jobs
might
need
completely
different
os
configurations
and
that's
no
problem.
Thanks
to
virtualization,
they
won't
interfere
with
each
other.
Much
if
you
set
it
up
right.
A
A
A
A
A
However,
I
soon
discovered
that
rebooting
the
system
from
software
didn't
work.
The
machine
would
instead
boot
to
the
bios
screen
and
sit
there
forever.
It
didn't
recognize
the
thumb
drive
on
a
reboot.
That
would
be
a
problem
for
the
remote
lab,
so
I
switched
to
a
newer
thumb.
Drive
unraid
does
allow
you
to
switch
to
a
different
thumb
drive,
but
the
automatic
procedure
for
doing
that
only
works
once
a
year.
A
A
A
A
A
Unraid's
primary
user
interface
is
through
web
pages,
which
you
can
bring
up
from
an
internal
vm
or
from
another
machine
with
access
to
the
local
network.
One
of
the
useful
screens
is
a
dashboard
status
display,
and
one
of
the
things
you
can
monitor
on
that
screen
is
the
temperature
of
the
cpu
and
disk
drives
when
idle.
The
spinning
disk
drives
run
pretty
cool,
but
the
cache
ssds
are
over
50
degrees
c,
despite
the
integrated
heat
sink
and
fan,
cooling
provided
by
the
motherboard
I'll
have
to
keep
an
eye
on
that.
A
On
the
other
hand,
the
manufacturer
only
rates
these
ssds
up
to
about
7
dc
chonck
also
features
a
high-end
graphics
card,
an
nvidia
geforce
rtx
3080.,
no
we're
not
planning
on
mining
bitcoin
or
playing
the
latest
video
game
at
a
high
frame
rate
with
the
highest
graphics
settings,
but
we
could
now.
The
graphics
card
is
for
developing
and
testing
signal
processing
code
for
dvb,
s2x
or
other
applications.
A
A
It's
as
if
the
device
didn't
exist
at
all
on
the
main
machine
or
in
any
other
vm.
The
vm
that
owns
the
device
can
treat
it
as
if
it
had
direct
access
to
the
hardware
which
it
effectively
does
graphics.
Cards,
in
fact,
are
the
most
common
use
case
for
mapping
pcie
devices
to
vms,
because
gamers
are
a
big
part
of
unraid's
customer
base.
A
A
A
The
usual
approach
would
be
to
designate
the
onboard
graphics
or
a
secondary,
inexpensive
graphics
card
as
the
console,
and
that
would
free
up
the
fancy
gpu
for
whatever
else
you
needed
to
do
with
it.
The
motherboard
that
we
use
in
chunk
doesn't
have
any
onboard
graphics
and
we
didn't
think
to
purchase
a
second
graphics
card
now.
It
is
possible
to
boot
unraid
and
still
have
the
one
and
only
graphics
card
mapped
to
a
vm,
but
it
isn't
at
all
straightforward.
A
A
The
windows
vm
was
able
to
run
the
benchmark
with
flawless
video
and
excellent,
measured
performance.
I
hope
this
means
that
gpu
programming
tools
will
be
able
to
run
on
the
system
as
if
running
on
standard
hardware,
only
one
vm
at
a
time
can
own
the
gpu,
but
it
is
possible
to
shut
down
the
vm
that
owns
the
gpu
and
boot
up
another
one.
So
it
also
owns
the
gpu
one
at
a
time.
