2. Agenda
• The
role
of
the
OS
in
applicaBon
delivery
• Oracle’s
two
OS’s
• Key
advantages
of
each
OS
• WHY
TWO???
• How
should
I
choose?

Like?

4. The
role
of
the
OS
in
applicaBon
delivery
• What
does
the
OS
actually
do
for
us?
• Do
some
do
different
jobs
bePer
than
others?
• NaBve
OS
features
versus
bolt-­‐on
features
• The
OS
is
NOT
unimportant
–
even
(or
especially!)
on
Hypervisors

5. Oracle’s
two
OS’s:
Solaris
and
OEL
• Solaris
–
Acquired
in
the
purchase
of
Sun
– Best
scaling
OS
– Largest
install
base
of
large
Oracle
installaBons
– Leader
in
performance
and
scale
in
many
categories
– Support
for
SPARC
and
X-­‐64
systems
from
many
vendors
– Comfortably
scales
beyond
512
threads,
TB’s
of
memory,
hundred
of
I/O
adapters

6. Oracle’s
two
OS’s:
Solaris
and
OEL
• OEL
–
refined
from
the
Red
Hat
source
base
– Now
Includes
Unbreakable
Enterprise
Kernel
by
default
– CAN
be
fully
Redhat
compaBble
– Supported
by
Oracle
for
enterprise
DB
before
any
other
vendor
– Used
in
original
Exadata

fresh

8. Key
Advantages
of
OEL
• Is
Linux!
(Some
organizaBons,
and
ISV’s
require
it,
aPracBve
development
environment.)
• Can
leverage
the
global
community
in
terms
of
available
applicaBons
and
OS
development
• Has
the
mindshare
as
‘Linux’,
which
is
separated
from
UNIX
• Support
on
a
variety
of
hardware;
though
OEL
is
only
X-­‐64.
• Support
for
many
devices

9. Key
Advantages
of
OEL
• Has
Bered
support
pricing
(Network,
Basic,
Premier)
• Is
more
familiar
to
School/University
leavers
than
UNIX
• Has
the
OVM
Hypervisor
as
an
opBon,
which
can
contain
OEL,
Solaris,
Windows,
etc.

10. Key
Advantages
of
Solaris
• Support
for
SPARC
hardware
– T-­‐series
systems
• Best
performance
per
waP
• Up
to
512
threads
in
5RU
• Consolidate
old
Solaris
systems
whilst
barely
breathing
– M-­‐series
systems
• mainframe
like
reliability
• HA
with
No
Single
point
of
failure
in
large
scale
systems
• Hardware
Domainable

11. Key
Advantages
of
Solaris
• Fastest,
highest
scaling,
most
resilient,
more
widely
supported
UNIX
• KEY
OS
capabiliBes
that
include
• Dtrace
• Resource
Management
• ZFS
• SMF
• Containers
• FMA
• SMF
• Full
support
for
LDOMS
• Branded
Containers
• Wholly
owned

12. Why
BOTH?
• Opportunity
to
make
the
best
of
all
worlds:
– Tightly
integrated
and
opBmized
for
the
total
Oracle
stack
– Opportunity
to
shape
the
OS
as
Silicone
is
developed,
and
take
advantage
of
it
first
– Tightest
integraBon
with
Oracle
DB
– Build
largest,
most
resilient
and
scalable
systems
– Many
elements
CORE
to
the
OS,
rather
than
bolt-­‐
on.

13. Why
BOTH?
• OEL
– Broad
compaBbility
with
Linux
Ecosystem
– Pricing
opBons
– Choice
of
Kernel;
Faster
and
bePer
scaling
Unbreakable
Enterprise
Kernel,
or
the
fully
RedHat
compaBble
Kernel

15. Wonder
Twin
Powers:
AcBvate!
• Both
OEL
and
Solaris
can
be
managed
by
OEM
Ops
Centre
• Using
OEM,
both
can
be
supported
by
the
one
support
team
from
an
operaBonal
perspecBve
• Regular
configuraBon
to
use
OEL
in
smaller
web-­‐
facing
environments,
and
Solaris
on
the
larger
systems
in
the
back-­‐end
• ‘Red
Stack’
–
It’s
actually
not
just
a
markeBng
thrust.

16. How
do
I
choose?
• SOE
/
Strategic
Architecture
/
Vendor
ojen
determines
rather
than
choice
• Where
more
business
criBcal,
higher
value
transacBons
are
involved,
Solaris
is
typically
a
bePer
choice
–
even
if
only
for
DTrace,
SMF
and
FMA.
• Horizontal,
node
based
scaling
typically
targeted
for
OEL.

17. The
best
of
both
worlds
• Whether
you
want
speed,
scale,
access
to
the
most
packages,
best
tools,
greatest
diagnosBc
capabiliBes,
highest
resilience,
Oracle
has
you
covered
in
the
Linux/Unix
space.
• OEL
6
has
released,
now
with
unbreakable
kernel
by
default
• Watch
this
space
for
Solaris
11
–
There
is
an
Express
Version
already
Available
• Wait
and
see
what
the
next
GeneraBon
SPARC
T-­‐
series
systems
can
do!

18. Summary:
• Typically
not
as
simple
as
one
or
the
other
• If
you
are
leaning
towards
verBcal
scale
and
high
value
business
transacBons,
Solaris
• If
you
need
greatest
reliability
or
diagnosability,
Solaris
• If
you
are
leaning
towards
lower
cost
compute,
or
business
transacBons,
OEL
• If
you
have
a
need
to
get
or
use
more
of
the
‘linux
/opensource’
community
sojware,
OEL.
• Frequently
use
both!
