A
All
right,
okay,
seven
minutes
why
parking
set
from
windows,
so
ceph
is
the
most
popular
distributor
on
open
source
target
solutions
out
there.
So
this
is
without
discussion
right
and
at
the
same
time,
windows
server
has
a
relatively
large
market
share,
especially
in
the
enterprise.
So
you
cannot
enter
a
large
company
these
days,
but
not
even
a
medium-sized
one,
without
finding
a
mixture,
of
course,
of
a
lot
of
windows,
servers
and
linux
servers,
and
so
on
so
having
something
that
will
bridge
the
gap
between
them
when
it
comes
to
storage.
A
It's
quite
ideal
in
this.
In
this
context,
of
course,
this
is
not
something
that
is
the
first
time
that
comes
up.
Actually,
companies
tend
to
use
a
lot.
This
is
called
sapphire
sketch
gateway
for
that,
but
there
have
been
always
a
lot
of
complaints
related
to
performance
and
scalability
for
that.
Okay,
so
that's
that's
something
that
we've
been
hearing
and
discussing
since
a
long
time,
and
finally,
recently
I
mean
approximately
one
year
ago,
we
started
actually
doing
all
this
work.
How
did
it
happen?
A
It
happened
thanks
especially
to
suzy,
so
big
kudos
to
to
suse
for
that,
especially
lars
and
mike
for
helping
a
lot
in
in
this
effort
working
with
absolutely
phenomenal
for
us,
and
we
managed,
thanks
to
this
partnership,
to
to
release
to
break
to
the
community.
Let's
say
this
particular
effort
for
for
the
party.
A
So
what
were
the
architectural
goals?
We
were
looking
at
to
begin
with,
we
wanted
to
have
a
user
experience
on
windows
which
was
as
close
as
possible
as
the
linux
one.
What
does
that
mean?
It
means
that
we
want
to
have
people
which
have
a
linux
experience
with
ceph
to
be
able
to
just
log
in
in
a
windows
server
and
find
themselves
at
home
as
much
as
possible
without
having
to
to
go
completely
to
a
new
learning
curve.
A
At
all,
okay,
so
those
were
some
of
our
goals
in
terms
of
user
experience
in
terms
of
performance,
we
want
definitely
to
outperform
the
ice,
casi
gateway,
otherwise
it
didn't
make
necessarily
too
much
sense
and
get
as
close
as
possible
to
the
linux
native
performance.
I
will
add
some
more
info
on
that
soon
secure
I
mean
it.
Anything
which
is
cloud
related,
of
course,
has
to
take
into
consideration
security
and,
in
terms
of
platform,
support.
We
wanted
to
have.
A
Windows
start
2016
and
19
as
default,
and,
of
course
it
will
support
also
the
upcoming
2022
version.
It
works
also
windows,
10
for
development
purposes
and,
of
course,
it
could
theoretically
work
on
also
in
previous
versions,
but
it's
not
something
that
we
we
plan
necessarily
to
support
at
the
moment,
non-goal
porting
osd,
directly
to
windows
so
right
now,
the
way
it
works
is
that
the
windows
server
nodes
will
connect
to
external
osd
nodes
to
access
the
storage
itself.
A
This
is
a
very
common
question,
especially
when
people
ask
it
with
how
it
compares,
let's
say
to
native
distributed
storage
options.
Okay,
a
quick
look
about
the
architecture,
so
here
we
have
the
the
windows
side
on
the
right
and
we
have
a
separate
user
space
and
kernel
space
space
part
the
user
space.
A
Actually,
that's
where
the
experience,
let's
say,
inspiration
for
that
came
from.
We
have
three
typical
command
that
we
use.
Rbd
will
be
the
map
and
map
and
list
specifically
due
to
rbd
volumes.
Okay,
images
mappings
are
managed
afterwards
by
a
windows
service,
meaning
that
if
you
reboot
the
host,
you
will
find,
of
course,
your
mappings
in
the
same
identical
place
from
a
user
perspective
and
from
a
operating
system
perspective,
the
rbd
images
will
just
look
like
regular
windows.
Disks
like
you,
would
expect,
with
iscsi
or
anything
similar
rbd
and
many
cli
tools
themselves.
A
Of
course
work
exactly
like
on
linux.
What
we
don't
have,
for
example,
there
are
a
bunch
of
python
specific
scripts
that
all
do
they
can
work
with
some
very
minimal
changes
on
windows
itself.
You
know
on
windows,
you
don't
automatically
associate
that
the
python
script,
let's
say
with
an
executable,
so
they
need
to
be
wrapped,
which
is
something
that
was
out
of
scope
of
what
we
needed.
So
you
cannot
just
run
seven
and
have
a
bunch
of
commands,
while
everything
will
say
executable.
A
It
implements
the
md
protocol
protocols.
That's
where
we
started
from
with
two
communication
options:
the
first
one
is
via
tcp,
which
is
compatible
with
any
linux
mbd
server.
Actually,
when
we,
when
we
designed
this-
and
we
worked
on
that,
we
wanted
it
to
work
like
in
in
in
order
to
be
able
to
work,
let's
say
with
any
ndp
server
itself,
so
not
only
ceph,
and
actually
it
still
allows
us
to
do
that.
But
performance
was
really
not
where
we
wanted
it
to
be.
A
So
what
we
did
is
that
we
did
is
that
we
developed
a
separate
user-space
camera
communication
channel,
which
proved
to
be
significantly
faster
and
allows
us,
of
course,
to
reach
the
performance
goals
that
we
wanted.
It's
licensed
it's
open
source
across
like
everything
else
that
we
did
here.
Lgpl
2.1,
to
be
also
consistent.
Let's
say
with
the
majority
of
the
safe
ecosystem,
and
it
currently
resides
at
the
github
repository
that
you
can
see
on
there
on
the
link
below.
A
Now,
let's
get
a
bit
on
the
how
the
configuration
works
you
know
on
on
linux,
you
will
find
everything
in
our
default
location
which
would
be
etc
self,
while
on
windows,
the
equivalent
of
vtc
will
be
program
data.
So,
for
example,
if
you
have
your
operating
system
and
everything
in
c,
that
would
be
the
column,
backslash
program,
data
and
then
self,
so
very
similar,
very
consistent.
Let's
say
in
how
it
works
on
linux,
so
the
typical
workflow,
considering
in
getting
ceph.cof
and
confident
keying
files
over
from
a
linux
node
install
windows.
A
A
There
are
a
bunch
of
them
in
the
community
and
after
we
looked
around
at
the
various
options,
we
decided
to
go
with
dokini,
which
is
a
very
stable
one,
works
extremely
well
and
we
are
very
happy
with
it.
So
that's
a
preach
that
needs
to
be
installed
in.
In
the
moment
we
choose
ffs
on
windows.
Beside
that,
of
course,
we
implemented
all
the
all
the
integrations
with
dockety
and,
and
it
works
like
you
would
expect
on
on
linux.
A
A
A
A
So
if
you
have
openstack
with
hyper-v
now
can
also
has
you
can
also
have
ceph
with
the
width
with
cinder
and
and
just
make
it
work
seamlessly
on
windows,
as
you
would
on
on
on
linux,
hyper-v
can
access
now
there
are
rbd
images
in
the
form
of
disk,
of
course,
and
you
can
also.
That
means
that
you
can
also
boot
dark
live
vm
from
an
rbd
image.
A
A
Let's
talk
quickly
about
performance,
so
we
had
a
very,
very
significant
improvement
over
the
ice
casing
gateway
and
in
our
tests
we
managed
to
outperform
also
the
linux
native
rbd
scenario.
Please
note
that
that
was
not
originally
what
we
wanted
and
it's
not
a
met,
a
matter
of
contest
I
mean
we
don't
want
to
say:
hey.
We
are
faster
than
linux,
okay,
so
that
was
really
never
ever
never
the
goal.
A
The
reason
why
it
happened
is
that
since
we
don't
use
the
tcp
overhead,
on
top
of
the
let's
say,
user
space
to
kernel
communication
part,
we
have
a
faster
communication
channel,
which
also
means
that
we
have
a
improved
the
io
worker
threads
allocation.
That
that's
why
this
happened.
Again,
we
tried
to
be
as
objective
as
possible.
A
A
A
A
A
A
As
you
can
see
right
now,
I
have
only
one
image,
which
is
called
hyper
v1
that
I
will
use
in
a
bit
here.
I
should
have
it
as
well.
Yes,
so
I
can
run
the
same
command
from
here
and
I
see
the
same
identical
details.
This
is
windows,
and
this
is
linux,
all
the
data.
Sorry,
I
mean
all
the
configuration
files
are
already
in
place.
I
already
put
them
there,
so
we
don't
have
to
spend
time.
A
A
A
A
A
A
Or
I
can
terminate
this
mapping
since
I
don't
need
it
the
windows
so
specifically
there.
There
is
already
an
rbd
image
called
hyperv1,
which
I
created
with
this
qemo
command,
which
I
don't
want
to
run
again,
but
just
to
show
you,
I
basically
converted
an
open
source,
a
qr2
directly
into
into
the
rbd
image,
which
I
call
hyper
v1,
which
I'm
not
running
just
because
it
takes
a
few
to
three
minutes
and
we
don't
want
to
spend
those
two
three
minutes
just
waiting
for
that.
Okay,
so
it's
already
there.
A
A
A
A
As
you
can
see,
we
didn't
copy
over
as
part
of
the
installer
any
specific
python
scripts
that
are
often
used.
Let's
say
in
the
in
the
management
of
observed
clusters.
The
reason
is
simple
that
for
that
we
will
also
need
a
python
environment.
I
mean
a
pattern
interpreter
which
is
not
available
by
default
on
windows
and
the
way.
Typically,
this
works
just
as
an
example
when
we
port
it
and
we
did
all
the
work
in
openstack,
which
is
entirely
python
based.
What
we
do
is
that
typically.
