The
Evolu@on
of
SoBware

•  The
@mes
the
are
a
changin
(Thanks,
Bob)

•  Much
less
about
what
the
vendor
gives
you

•  Much
more
about
what
the
business
wants

the
applica@on
to
do,
with
a
range
of
op@ons

•  Inﬂuenced
by
open
development

•  Inﬂuenced
by
compe@@on

•  Modularity
is
prolifera@ng


The
Evolu@on
of
SoBware

•  Many
systems
being
replaced
are
from
the

monolithic
era.

•  New
systems
are
typically
much
more
externally

dependent
rather
then
request
/
result

•  Custom
Binaries
in
C
have
moved
more
and
more

to
layered
architectures,
J2EE,
Web+App+DB,

message
busses
and
more

•  Ruby,
Python,
JAVA,
C#
-‐
all
have
considerable

system
level
impact


Assump@ons
of
New
SoBware

•  New
SoBware
oBen
makes
New
System

assump@ons

•  Much
of
the
new
soBware
out
there
expects

–  Huge
amounts
of
memory

–  Many
threads

–  Very
low
latency
interconnects

–  CPUs
with
hardware
support
for
many
func@ons


Solu@on
when
SoBware
and
Hardware

are
not
a
good
match?


The
Progression
of
Hardware

•  CPU’s
no
longer
gedng
drama@cally
faster
in

a
straight
line
–
but
are
gedng
WIDER

•  CPUs
gedng
more
capability
in
silicone

•  Memory
System
bandwidth
increasing
–

though
latency
is
not
improving

•  Memory
density
increasing,
but
also
not

progressing
nearly
as
fast
as
applica@ons
can

use
it


The
Progression
of
Hardware

•  Interconnects
have
improved

•  Busses
and
loops
have
given
way
to
fabrics

(SAS,
PCI-‐E,
Inﬁniband)

•  ‘Commodity’
is
a
commodity
term.

•  Focus
is
oBen
on
CapEx
–
though
oBen
at
the

expense
of
OpEx.


Interconnects


Interconnects
and
caching

•  10Gbe
Now,
40
and
100GbE
coming
soon

•  QDR
Inﬁniband
here
now
(40Gbps),
EDR
and

FDR
already
releasing

•  FLASH
(Ah
aaaaaah)

•  SoBware
gedng
much
smarter
about
using

@ers
WITHOUT
external
assistance
(eg:
11gR2

using
ﬂash
directly)


Hypervisors
are
cool,
right?

•  To
V
or
not
to
V!

•  Why
do
we
Virtualize?

•  Regularly
required
because
‘the
hardware
is
too

big’,
and
because
commodity
hardware
lacks

many
of
the
safeguards
of
Enterprise

•  The
an@thesis
of
what
makes
sense
in
‘large

systems’.
S@ll
has
value
(eg:
Availability)

•  Many
and
varied:
Which
should
you
use?
When

should
you
use
them?


Clawing
back
the
Datacentre

•  Racks
of
old
systems
can
be
consolidated
into

RU’s
of
space

•  Do
in
200W
what
previously
took
2000W

•  Legacy
support
costs
can
be
crippling

•  Message
passing
speed
of
older
plamorms

(using
PCI,
PCI-‐X)
are
slower.
Today
is
all
about

message
speed

•  Increased
reliability:
ECC,
Checksums,
etc.


Exclusive
Convergence
vs
Solu@ons

•  Many
vendors
have
their
own
‘convergence’

•  Most
are
claimed
to
be
designed
with
a
‘system’

approach
in
mind,
and
are
pitched
as
a

‘architected
solu@on’

•  Many
solu@ons
are
incompa@ble
and
force
you

into
that
vendors
idea
how
it
should
be
done.

•  The
Oracle
value
is
that
you
can
use
best
of
breed

components,
OR
allow
Oracle
to
provide
the

en@re
stack.


COST

•  New
hardware
delivers
more
bang
for
buck

•  Oracle
Core
Factor
-‐
.25
for
T3,
.5
for
M-‐series

and
X86,
1
for
P-‐series,
and
Itanium
largely

irrelevant!
;)


Lifecycle
WIN
vs
Expenditure
FAIL

•  Infrastructure
is
typically
only
a
small
component

of
an
IT
project.

•  It’s
typically
the
one
chance
for
a

to
change
it’s

deployment
architecture
and
to
get
onto
the

latest
and
greatest
hardware

•  Provides
the
opportunity
to
build
the
right
sized

infrastructure
rather
than
guessing

•  CPU
capabili@es
will
be
tracking
soBware

developments.
Eg:
DB
speciﬁc
instruc@ons


It’s
great
news:

Your
applica@on
can
be
fast.


Get
the
MOST
from
your
SoBware

•  Understanding
your
soBware
helps
architect
a

system
to
suit
it

•  Select
the
right
CPU
architecture
type

•  Select
the
right
memory
architecture

•  Balance
I/O

•  Use
teiring
intelligently,
not
just
because
you

can

•  Agility
in
deployment:
Virtual
versus
Physical


Summary:

•  Running
new
soBware
on
previous
genera@on

hardware
is
fraught
with
danger

•  Many
soBware
assump@ons
don’t
stack
up
on
old

hardware

•  Many
applica@ons
actually
require
instruc@on
set

support
to
run
at
their
best

•  To
get
the
most
from
your
soBware
applica@ons,

the
best
start
you
can
give
them
is
a
fresh
batch

of
@n.
