Description
Ceph Practice And Usage In China Mobile - Zhang Shaowen, China Mobile (Suzhou) Software Technology Co., Ltd
China Mobile has used Ceph storage since 2016. Up to now, China Mobile has built hundreds of petabytes of block and object storage based on Ceph to support its own business. Besides, it also expands to external markets, including finance, education, government, etc. A large number of projects have helped China Mobile accumulate a lot of experience in using Ceph. This proposal introduces the use case and best practice in Ceph according to China Mobile's experience.
About Zhang Shaowen
Senior Engineer, China Mobile (Suzhou) software technology Co., Ltd
I've worked in China Mobile for 3 years and began to work on Ceph in 2016. Now my work is focused on object storage. I've got a little speaking experience, | but haven't got a chance to make a speech in a | big conference.

we

A

This

engineer
at
first
we
didn't
have
this
management
platform
and
as
a
monetary
and
allow
me
where
sources
were
all
connected
to
the
companies
dedicated
a
monitoring
platform.
However,
in
the
actual
project
we
found
that
the
customers
demand
for
the
management
platform
is
very
urgent
and
the
management
requirements
in
the
binding
of
some
projects
intention
the
current
self

and
mentions
the
management

is
relatively
high
beyond
the
campus
cabinetries
of
the
general
enterprise.
A
Yeah
and
see
different
hardware
can
provide
a
different
performance.
We
have
a
suite
to
be
Co
hardware
configuration
to
meet
a
different
user
requirements.
The
first
one
is
the
caps
T
type,
it
uses
SSD
a
toastie
journal
and
we
can
use
the
2
SATA
SSD
or
just
the
one
in
PCIe
SSD
to
hold
it.
You
know
they
turn
the
caps
t-type
had
higher
cavity
and
the
lower
crust
and
is
used
to
her
decoded
data.
The
second
one
is
the
balanced
type.
It
also
uses
SSD
to
hold
journal
data.
A
Besides,
it
used
be
catch
catch
data
to
improve,
read
opponents.
The
balanced
type
is
a
high
cost
effective
and
is
used
as
data
theory
to
hold
a
woman
at
home.
The
last
one
is
the
performance
type
which
doesn't
use
use
fgd
anymore.
Instead,
it
consists
of
ossd.
We
can
also
add
PCIe
SSD
to
hold
a
journal
data
for
further
improving
writer
performance.
A
How
did
this
hire
is
data
that
needs
to
be
accessed
the
frequently
for
the
data
we
can
put
it
on
high-speed
flashed,
so
the
latency
of
access,
a
low-cut.
The
data
is
the
data
that
is
existence
less
frequently
by
users.
It
is
usually
stored
on
lower
performance
me
and
less
expensive
story
like
HDD
how
to
achieve
higher
performance
with
a
lower
cost.
It
was
thinking
we
think
using
catch
is
one
of
the
solutions.
A
A
The
iope
has
a
longer
in
some
iowa
sinner
is
using
catch
serving
may
even
cost
performance
deprecated.
So
we
choose
a
way
to
speed
up
the
palaka
device.
Will
OSD
catch
in
the
linux
kernel
blocker
there,
sir,
for
a
mature
solution
to
speed
up
the
HDD
with
the
SSD,
the
fresh
catch
he
has
iowa
TM
catch
and
the
big
catch
after
compression
of
a
visa
for
seniors.
We
chose
because
our
caching
solution.
A
Among
the
open
source
solutions,
the
first
three
cache
block
index,
seeing
algorithm
smilla,
say
app
based
on
the
hash
index,
the
biggest
difference
between
P
cache
and
his
other
is
that
it
uses
a
peep
peep
as
cheap
as
the
index,
and
the
hit
rate
will
be
quickly
improved.
At
the
same
time,
it
takes
into
account
some
of
the
characteristics
of
the
SSD
itself
in
the
architecture
design,
while
maximum
the
performance
of
the
SSD,
it
also
protects.
The
life
of
the
SSD
below
is
the
effect
of
a
flash
cache
and
be

with
the
GC
mechanism.
