B
A
A
B
B
A
A
A
Personal
okay,
let
me
see
if.
B
A
A
There
you
go
in
that
comment,
icon
on
the
top
right
corner
next
to
share.
If
I
click
that
I
see.
A
I
will
oh,
this
is
also
for
the
the
survey
interface
right
you're,
given
some
of
it
make
the
make
this
multi-choice,
not
radios
buttons.
That's
for
the
question
content
right,
for
example,
yeah,
the
one.
B
A
A
So
I
didn't
looks
like
there
is
no
other
comment
that
was
added
I'll
work
on
this
today
and
put
them
in
place
so
that
mike
can
we
we
need
to
finalize
this
next
week.
I
guess
right.
A
And
see
if
this
is
sufficient
list,
probably
having
a
priority
of
what's
important
for
us
after
this
question
list,
or
there
are
others
that
need
to
be
added
I'll,
make
another
sheet
here,
step
2020
user
survey
and
then
start
listing
down
the
question
list
based
on
comments
and
then
at
least
the
content
part
will
get
ready
and
the
navigation
and
other
pieces
we
can.
A
I
don't
know
how
much
of
it.
Basically,
we
have
to
go
through
that
tool
and
see
if
we
need
to
make
changes
in
the
way
we
navigate
through
the
questions,
as
the
survey
appears,
yeah.
B
I
haven't-
I
haven't
looked
at
that
yet,
but
I
can
offer
some
thoughts
based
on
on
they're,
like
they're,
like
sites
that
do
surveys
where
you
can
get
points
to
to
get
like
airline
miles
or
other
things,
and
I
use
them
to
get
a
few
miles
to
keep
my
my
airline
miles
from
expiring,
and
one
thing
I
hate
is:
when
a
survey
doesn't
give
you
any
idea
of
progress
of
you
know
how
yeah,
how
much,
how
much
more
you
have
to
endure.
B
Should
we
should
let
the
user
you
know,
even
if
that
just
means
saying
up
front
there
are
you
know
50
questions
or
whatever.
A
B
A
Right
progress
of
the
survey
indicator
that
is
needed
right.
B
A
Right,
whichever
is
the
easiest
way,
we
can
put
that
just
on
one
of
one
of
the
corners
we
can
simply
say
10
out
of
50
or
whatever.
That
number
is
right,
but.
B
A
Meaning
you
mean
to
say
the
the
other,
the
last
discussion
it
was
like
you
know
if
I
choose
a
one
particular
option
there
on
that
survey,
and
you
answered
that
question
based
on
that
it
will
pop
up
other
questions
right.
So
it's
not
a
fixed
list
of
questions.
A
That
was
what
mike
was
telling,
and
if
that
is
the
case
right,
we
don't
know
how
many
total
questions,
but
at
least
in,
in
which
case
that
that
will
be
difficult
right.
We
wouldn't
know
how
long
the
survey
would
go
like
that.
Based
on
the
answer,
if
you
are
giving
more
questions,
even
if
that
has
a
max
limit,
okay,
there
will
be
about
20
questions
or
10
more
questions
that
will
be
helpful
right
now,
they're
just
some
idea.
A
A
Right
some
idea
on
how
many,
how
many
more
questions
are.
B
Yeah,
because
you
know
I
you
know,
get
these
surveys
where
they
give
me
page
after
page
where
they
list
like
three
things.
You
know
five
things
and
I
have
to
rank
them
and
the
next
one
it
gives
me
like
it
swaps
out
one
of
them
for
another
thing
and
wants
me
to
rank,
and
then
it
gives
me
like
20
of
those
in
a
row,
and
it's
like
this
is
and
that's
a
survey
off
literally.
A
Yes,
certainly
yeah,
and
the
first
point
that
you
said
was
some
kind
of
incentive
right
like
air
miles
or
is
that
what
you're
thinking.
B
A
Okay,
okay,
okay,
so
progress
indicator
and
then
some
idea
on
how
many
questions
they
need
to
be
answered,
and
then
the
other
piece
to
that
was.
A
As
you
start,
the
survey
would
we
have
categories
listed
and
they
can
choose
depending
on
the
user.
You
know
some
are
some
could
be
developers,
some
could
be
admins,
some
could
be,
you
know,
application
developers
and
they
might
are
systems
engineers
they
might
have
their
choice
of
what
questions
are
important
to
them.
A
Of
course,
the
first
few
can
be
like
you
know
the
where
they
are
the
geo
and
the
industry
that
they're
working
and
those
kind
of
general
questions
are
okay.
But
beyond
that,
if
we
can
target
to
their
specific
users
types,
then
it
will
be
much
more
interesting
for
them
right.
Would
you
would
that
be
a
good
one
to.
B
B
B
27.,
it
might
be
interesting
to
break
out
to
add
an
amd
choice
in
there.
A
A
Let
me
search
for
that.
One
cpu
right.
A
B
Or
processor
architecture
to
use,
let
me
go
back
up
here
and
see.
A
A
A
Yeah,
yes
from
a
let's
say
for
for
csps
right
cloud
service
providers,
they
would
like
to
have
a
leaner
rack
space,
and
if
you
have
this
scale
form
factor
drives,
then
they
can
bunch
in
a
bunch
of
group
of
those
drives
and
make
their
racks
much
more.
You
know
slim
climber
right
with
all
their
drives
together.
A
It
can
have
a
larger
capacity,
but
then
take
much
less
space
than
you
know.
You
fit
that,
of
course,
it
would
need
appropriate
ports
on
the
servers
to
attach
these
scale
form
factor
drives,
but
certainly
we
at
least
from
intel
side.
I
know
there
is
a
demand
for
it.
In
fact,
somebody
else
was
telling
right
they
wanted
that
in
the
last
call,
I
don't
remember
who.
A
A
A
Yeah,
so
maybe
that
might
be
a
good
one
to
add
dry
form
factors.
B
A
Oh
from
a
step
standpoint
yeah,
yeah
yeah,
but
this
is
mostly
a
more
of
a
infrastructure
question
right
from
a
safe
standpoint.
It
might
not
make
a
difference
from
software
and
as
long
as
there
isn't
any
dependency
that
ceph
has
on
a
particular
media
type
or
rather
form
factor
right.
You
have
the
right
driver
and
other
things
that
it
will
support.
Yeah.
A
A
Okay,
one
thing
which
I
did
not
see
here
is:
would
would
it
be.
A
They
are
both
multi-choice
make
sure
it
is
multi.
Multi-Choice
question.
A
Okay,
the
other
part
was
about
the
cpu
sockets
single
socket
versus
you
know.
Multi-Socket.
Would
that
be
of
interest.
A
Yeah
there
isn't
one
here,
there
is
cpu,
but
it's
just.
A
Socket
yeah,
it's
not
finding
anything
in
here,
maybe
in
2018
socket!
No,
it
doesn't,
I
think,
adding
one
question
on
that.
Certainly
it
would
be
meaningful.
A
lot
of
yeah
cost
performance
price
performance
right
with.
B
A
A
Four
yeah:
there
is
nothing
about
pneuma.
Certainly
that
should
be
there.
A
Question
one
number
of
seconds
and
of
course
yeah.
Probably
in
that
question
we
should
also
include
a
you
know
they
would
they
prefer
higher
smaller
number
of
cores
or
lower
frequency.
More
number
of
cores.
A
B
Question
is
but
yeah
so
like
the
like.
You
know
if
you
have
an
osd
node
with
like
24
osds
on
it
you're
going
to
favor.
You
know
a
higher
core
count,
but
people
running
an
mds.
B
A
Right
and
do
you
think
most
installations
have
them
dedicated,
like
you
know,
monitor
you
just
keep
a
monitor,
node
and
don't
put
a
club
it
within
osmena.
B
A
B
A
B
A
Yeah
yeah
there
isn't
one
on
that.
How
do
we?
How
do
you
frame
that
which
is
the
layout?
That's
that's
a
different.
B
I
would
say:
just
do
you
do,
do
you
run
dedicated
mod
notes?
A
A
A
Yes,
there
is
yes,
oh.
A
Two
three
backup
big
data
analytics
archive
other
archive
backup,
big
data
analytics
other
know
that
for
our
data
rdw,
where
do
we
have
one
for
rjw,
apis,
s3,
swift,
rgw
admin,
api,
nfs3
export
and
there's
lib
rbd
put
lip
rbd,
there's
a
boot
boot
virtual
machines
database,
other
that's
the
one.
I
think
that
might
is
there
anything
else.
Should
we
big
data
and
analytics?
Would
that
be
a
sufficiently
big
bucket
to
include
ai
and
ml.
B
Yeah,
I
wouldn't
get
too
obsessed
there,
but
back
under
under
the
the
rbd
question,
though
I
would
just
say
virtual
machines,
not
boot
virtual
machines.
A
B
A
Yeah
I
was
telling
the
same
thing,
but
I
found
that
what
are
the
use
cases
for
sep
clusters
it's
in
there,
but
it's
not
a
yeah.
It's
a
different
kind
of
question
in
the
rbd
one
back
to
rbd.
Let
me
go
back
to
rpd.
A
Right,
let
me
go
to
that
containers,
question
again:
containers,
that's
question
38
and
rbd.
A
Rbd
workloads
merge
this
into
question.
38.
A
A
The
other
ones
are
openstack
cloud
stack,
ecolyptus,
open,
nebula,
kubernetes,
vmware
windows,
hyper
way,
proxmox
kvm,
zen
rbd
directly
on
the
net
systems.
Those
were
the
options.
B
Didn't
nebula
shut
down.
A
Right,
that's
another
thing
we
need
to
keep
track,
of
which
ones
become
obsolete
or
kind
of
well.
A
A
A
A
Did
you
say
open
shift
or
open
container
storage?
I
don't
know
open
shift,
comma,
open,
container
storage.
A
Yeah,
that's
from
in
the
context
of
openshift,
it's
popularly
or
may
not
be
popular
yet,
but
commonly
called
ocs
open
containers.
Basically,
it's
the
it
is
underneath
ocs
is
basically
ceph
right.
Redact
moved
away
from
their
general
storage
solution
on
openshift
with
cluster
fs
to
ceph
like
they
don't
they
don't
stop
their
default.
Storage
support
is
not
cluster
fs
anymore,
it's
ceph
so
that
that's
what
they
call
as
open
container
storage.
B
A
A
What
else
yeah
all
the
ones
that
are
marked
in
red
in
the
2019
and
some
of
those
should
be
back.
I
think
right,
yeah,
the
red
means
it
was
not
part
of
the
2019
survey.
It
was
increased.
B
A
Yeah
red
means
they
were
dropped.
What
are
the
interfaces
used
to.
B
B
A
A
A
Used
on
the
cluster
right
block,
object
file,
fps
librarados.
What
are
the
interfaces
used?.
A
No,
the
question
we
asked
was
a
different
one,
which
was
rados
block
device.
What
is
it
rbd
workloads?
Those
were
workloads
right,
not
the
interfaces.
A
Where
else
did
we
did
we
use
rgw
elsewhere
or
liberators
vibratos
programming
language?
Did
it
come
in
there
liberators?
No,
it
came
here.
There
are
three
references
to
it.
That's
one
which
is
part
of
the
interface
question
environment
status
report
response
count.
A
A
A
B
A
B
A
A
A
Should
we
go
to
that
which
one
not
more
popular
melanox
or
somebody
else.
B
A
Because
we're
asking
amd
and
power
and
intel
and
all
that
but
similar
one
applies
to
the
nick
cards
as
well.
Right,
yeah.
B
I
mean
I
don't
think
seth
cares
that
much
as
much
about
that
than
the
cpu.
So
yeah,
I
don't
I
don't
I
I
don't.
I
don't
see
a
value
in
that,
but
but
the
block
object
file,
liberators
question:
where
are
we
going
to
bring
that
back.
B
A
A
Definitely
that'll
be
useful.
Let
me
who
joined
us-
stefan,
oh
great
hi,
stefan.
A
B
B
B
A
A
A
Yeah,
okay,
all
right!
Let
me
use
that
one,
then
that's
a
request
for
this
one.
B
B
A
A
Yeah
going
through
the
sheet
and
identifying
with
questions
would
make
sense
to
bring
back
and
change
the
content
and
yeah
sure
adding
new
stuff.
All
of
those
things,
and
also
one
of
the.
A
Individual
task
items
we
had
was
to
go
through
this
individually
and
then
add
comments,
so
even
if
we
cannot
cover
it
in
this
meeting,
please
at
any
time
you
get
some
time
put
in
your
comments.
A
A
A
A
B
Less
than
they
used
to
be
yeah,
I
I
guess
I
I
yeah.
I
there's
this-
this
module
in
the
manager
now
that
you
can
send
telemetry,
and
it
might
already
do
most
of
the
answer
most
of
the
questions
in
this
questionnaire
as
well.
We
don't
know
well
yeah.
Well,
it
doesn't
help
for
the
people
running
older
releases,
though
or.
B
B
A
That
question
the
one
underneath
it
row
number
113
and
column
f.
B
B
B
B
That
was
a
big
question,
but
like
especially
after
cern's
big
bang,
the
scalability
has
really
increased
and
there
are
any
number
of
people
running.
You
know
a
thousand
to
two
thousand
osb
clusters
right
and
so
yeah.
I'm
not
sure.
I
don't
know
that
that
either
of
these
here
that
they
should
be
included
really
give
us
any
value
and.
A
Even
that
one
right,
whether
that
would
make
sense
did
I
say
it
should
be
included.
We'll
just
put
a
question
mark
in
here-
need
more
clarification.
B
A
Okay,
disagree
remove
yeah
good
likewise,
which
osd
back
ends
are
used.
This
was
covered,
I
think
right,
so
we
don't
need
that.
A
Yeah
the
blue
store,
oh,
that
was
not
yeah
blue
store.
Xfs
I
mean
now,
I'm
seeing
more
and
more
people
are
moving
to
blue
store.
A
Yeah,
that
certainly
is
not
you,
so
what
kind
of
redundancy
is
used
to
application
and
erasure
coding.
A
A
B
But,
for
example,
you
know
in
in
use
cases
for
cold
data.
You
know
there
are
use
cases
for
rbd
for
cold
data
and
cold.
You
know,
you
know
just
archival
data,
yeah
stuff
stuff
that
doesn't
get
read
very
often
right
then
ec
is
is
not
a
bad
approach
there,
I'm
planning,
you
know,
I.
I
have
a
bunch
of
old
clusters
where
I
am
now.
B
The
management
wanted
me
to
use
ec
on
all
of
the
new
ones
that
I'm
replacing
them
with,
but
some
of
those
clusters
are
going
to
have
six
nodes
and
it's
like
yeah.
No,
that's
not
a
good
use
case
for
esc,
but
I
have
a
a
big
archival
cluster
that'll.
Have
you
know
like
200
osds
and
that's
much
more
reasonable
to
use
you
see
on.
A
A
A
So
yeah
this
is,
this
is
a
even
if
you
put
that
question
it
is
difficult
to
answer
right.
It
doesn't
make
sense
just
with
that
yes
or
no
kind
of
question
with
what
kind
of
redundancy
is
used.
A
A
B
So
the
k
n
m
levels-
I
I
don't
see
how
that
would
be
useful.
I
would
think
that
the
ec
plug-ins
would
have
some
utility,
but
I'm
confident
that
almost
everybody
is
gonna
either
not
answer
it
or
say:
j,
erasure.
A
B
A
B
One
yep
yeah
I've
never
run
set
ffs.
So
my
knowledge
of
it
is
limited.
Okay,
yeah
so
yeah,
but
this
question
makes
sense
yeah
yeah,
because
when
I
first
read
that
I
thought
it
had
to
do
with
the
the
tunable,
what
is
it
mon
osd
down
out
subtree
limit?
B
B
B
Yeah
multi
multi
mds
ffs,
okay,
62
number
of
active
mds;
okay.
So
it's
already
there.
It's
active
62.
A
B
There
we
go,
oh
yeah
number
affected
them.
Yes,.
A
Yeah
correct,
there
was
no.
This
was
basically
in
the
future
which
wish
list.
B
B
A
B
B
A
A
What
happened
here?
The
net
promoter
score
yeah,
don't
know
why
it
is
a
duplicate
which
was
there
another
one.
B
A
B
B
B
Yeah
and
then
the
same
with
42
and
34..
These
these
numbers
are
just
not
in
order
it's
very
confusing.
A
Yeah,
so
when
I
put
this
in
place,
I
had
to
put
this
in
this
fashion
to
map,
because
I
put
these,
I
added
the
questions
later
on,
and
then
I
followed
the
sequence
of
the
survey
in
question
numbers,
so
I
had
already
bucketized
these
questions
into
some
groups,
relevant
groups,
but
then
the
sequence,
and
if
the
questions
were
asked
in
the
survey
were
different,
so
I
had
to
put
these
that's
why
it's
unordered
all
over
the
place.
A
Maybe
we
can
change
that
later
on
yeah,
but
this
is
anyway
a
duplicate
duplicate
of
question.
10
then
maybe
yeah,
like
you
know,
anthony
had
already
given
for
you.
Stefan,
if
you
look
at
this
comment
section
here
of
papo,
he
has
put
a
lot
of
comments.
We
can
continue
that
this
week
and
add
some
more
or
directly
add
comments
in
here.
A
Both
are
okay
right.
We
are
at
the
top
of
the
hour,
so
I'll
just
send
out.
You
know
just
the
meeting
notes
with
what
we
did
today
and
then
schedule
one
for
next
week.
A
I
think
if
the
content
portion
is
ready,
then
rest
of
it
is
just
the
the
format
right
usage
there
are
there.
I
put
one
more
tab
here
that
2020
survey
the
third
one
now
this
is
basically
I'll.
Just
modify
update
this.
If
you
go
to
that
and
means
inputs
on
way.
A
A
B
A
And
stefan,
you
also
got
the
link
right
that
mike
sent
for
the
survey.
Yes,
I
did
yeah,
