The
Simple
Idea
for
addressing
the
complexity
of
storage
management

ASM
History
101

•  Provides
an
integrated
cluster
volume
manager
and
file
system

•  Stripes
and
mirrors
files
across
disks
in
ASM
Disk
Groups

•  AutomaFc
rebalances
aêr
storage
configuraFon
changes

•  Built
on
the
Oracle
instance
architecture

•  I/O
operaFons
DO
NOT
go
through
the
ASM
instance!

•  Manages
storage
as
a
global
cluster
of
shared
Disk
Groups

•  ACFS
extends
the
ASM
management
umbrella
for
non-‐database
data

•  ASM
along
with
ACFS
define
the
Oracle
Storage
Stack

Value
of
the
Oracle
Storage
Stack

•  The
Oracle
Storage
Stack
began
with
the
development
of
ASM
and
greatly

simplified
Oracle
database
storage
management.

•  ACFS
introduced
in
11.2
extended
data
type
coverage
for
all
data.

•  Support
in
ACFS
for
databases
provided
new
choices
for
DBAs
for
managing

database
data.

•  The
Oracle
Storage
Stack
provides
a
single
comprehensive
storage
and
data

management
soluFon
required
of
enterprise
applicaFons.

•  Oracle
12c
Release
2
introduces
Storage
Management

for
greater
management
efficiency,
data
reliability
and

mobility.

Why
Are
You
NOT
Using
ASM?

•  Deploying
small
databases
using
local
or
3rd
party
file
systems

– As
you
grow,
managing
many
independent
volumes
and
file
systems
will
become

overwhelming
and
inefficient!

– For
clusters,
using
3rd
party
volume
managers
and
file
systems
with
Oracle
database

is
far
less
robust.

•  Deploying
databases
on
NFS
filers

– If
you
have
standardized
on
NFS,
then
consider
the
storage
management
advantages

of
layering
ASM
on
NFS.

– ASM
on
NFS
is
no
less
performant
than
NFS
alone

•  ASM
is
Oracle’s
strategic
plasorm
for
managing
all
data
