Maximizing Oracle Database performance with Intel SSD DC P3600 Series NVMe SS...Principled Technologies
If your organization runs critical, high-demand databases in environments such as Oracle Database, strong performance is not an option: it’s a must-have. Additionally, getting that necessary strong performance out of a single server can be essential for running a space and cost-efficient datacenter. In the Principled Technologies labs, we found that the Dell PowerEdge R930 offered strong performance for such transactional databases when configured with SATA SSDs. When we upgraded the servers to Intel SSD DC P3600 Series NVMe SSDs, performance doubled, increasing by 2.17 times, or 117 percent. If your datacenter needs a new powerhouse server, purchasing your Dell PowerEdge R930 with Intel NVMe SSDs for a cost increase of only 18 percent can double the performance you get from each server. This increases what your infrastructure can do within the same amount of space and lets you ultimately save money that would otherwise be spent purchasing additional servers and software.

The PowerEdge R750 solution boosted performance compared to a previous-generation PowerEdge R740 with PERC 10
Conclusion
Companies increasingly turn to big data applications to solve business problems such as understanding customer habits and behavior, maintaining electronic health records, and detecting fraud. In a 2022 survey of executives, 97.0 percent had invested in big data initiatives, and 73.7 percent said their organizations had appointed a Chief Data Officer (CDO), up from 12 percent in 2012.
With so much data at play, storage becomes an essential consideration for companies as they select hardware platforms to run their vital workloads. Two primary requirements for storage are fast performance and redundancy. Companies seek storage that can quickly put actionable insights into the hands of decision makers. At the same time, it is a fact of life that storage media occasionally fails, and no company wants to risk the potentially very large expense of losing vital business data.
In our testing with a disk-intensive TeraSort big data workload, we found that a current-generation Dell PowerEdge R750 server with a Broadcom-based Dell PERC 11 RAID controller with NVMe SSDs outperformed a previous-generation PowerEdge R740 server with a Dell PERC 10 RAID controller. The newer PowerEdge R750 solution completed the workload in 13.9 percent less time and with 16.3 percent better throughput, indicating that it could speed the delivery of insights to decision makers. With its PERC 11 RAID controller, it also offers RAID support for today’s speedy NVMe SSDs. Data-driven organizations must weigh the cost savings of putting off purchases of newer servers against the benefits of investing in those same newer, more powerful servers with RAID support for NVMe drives. Our testing shows that with the Dell PowerEdge R750 server with a Broadcom technology-based Dell PERC 11 RAID controller, buyers need not choose between redundancy and high performance.
By upgrading from the legacy solution we tested to the new Intel processor-based Dell and VMware solution, you could do 18 times the work in the same amount of space. Imagine what that performance could mean to your business: Consolidate workloads from across your company, lower your power and cooling bills, and limit datacenter expansion in the future, all while maintaining a consistent user experience—the list of potential benefits is huge.
Try running DPACK, which can help you identify bottlenecks in your environment and inform you about your current performance needs. Then consider how the consolidation ratio we proved could be helpful for your company.

Workstations powered by Intel can play a vital role in CPU-intensive AI devel...Principled Technologies
In three AI development workflows, Intel processor-powered workstations delivered strong performance, without using their GPUs, making them a good choice for this part of the AI process
Conclusion
We executed three AI development workflows on tower workstations and mobile workstations from three vendors, with each workflow utilizing only the Intel CPU cores, and found that these platforms were suitable for carrying out various AI tasks. For two of the workflows, we learned that completing the tasks on the tower workstations took roughly half as much time as on the mobile workstations. This supports the idea that the tower workstations would be appropriate for a development environment for more complex models with a greater volume of data and that the mobile workstations would be well-suited for data scientists fine-tuning simpler models. In the third workflow, we explored tower workstation performance with different precision levels and learned that using 16-bit floating point precision allowed the workstations to execute the workflow in less time and also reduced memory usage dramatically. For all three AI workflows we executed, we consider the time the workstations needed to complete the tasks to be acceptable, and believe that these workstations can be appropriate, cost-effective choices for these kinds of activities.

In our EBS-backed comparison, Dell APEX Block Storage for AWS offered 2.2x the throughput per node on sequential read operations vs. Vendor A.
Plus, the ability to scale beyond three nodes—up to 512 storage nodes with capacity of up to 8 PBs—enables Dell APEX Block Storage for AWS to help ensure performance and capacity as your team plans for the future.
Get in and stay in the productivity zone with the HP Z2 G9 Tower WorkstationPrincipled Technologies
We compared CPU performance and noise output of an HP Z2 G9 Tower Workstation in High Performance Mode to Dell Precision 3660 and 5860 tower workstations in optimized performance modes
Conclusion
HP Z2 G9 Tower Workstation users can change the BIOS settings to dial in the performance mode that best suits their needs: High Performance Mode, Performance Mode, or Quiet Mode. In good
news for both creative and technical professionals, we found that an Intel Core i9-13900 processor-powered HP Z2 G9 Tower Workstation set to High Performance mode received higher CPU-based benchmark scores than both a similarly configured Dell Precision 3660 and a Dell Precision 5860 equipped with an Intel Xeon w5-2455x processor. Plus, the HP Z2 G9 Tower Workstation was quieter while running CPU-intensive Cinebench 2024 and SPECapc for Solidworks 2022 workloads than both Dell Precision tower workstations. This means HP Z2 G9 Tower Workstation users who prize performance over everything else can do so without sacrificing a quiet workspace.
Open up new possibilities with higher transactional database performance from...Principled Technologies
In our PostgreSQL tests, R7i instances boosted performance over R6i instances with previous-gen processors
If you use the open-source PostgreSQL database to run your critical business operations, you have many cloud options from which to choose. While many of these instances can do the job, some can deliver stronger performance, which can mean getting a greater return on your cloud investment.
We conducted hands-on testing with the HammerDB TPROC-C benchmark to see how the PostgreSQL performance of Amazon EC2 R7i instances, enabled by 4th Gen Intel Xeon Scalable processors, stacked up to that of R6i instances with previous-generation processors. We learned that small, medium-sized, and large R7i instances with the newer processors delivered better OLTP performance, with improvements as high as 13.8 percent. By choosing the R7i instances, your organization has the potential to support more users, deliver a better experience to those users, and even lower your cloud operating expenditures by requiring fewer instances to get the job done.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

DELL POWEREDGE R930 WITH ORACLE: THE BENEFITS OF UPGRADING TO
PCIE STORAGE USING SANDISK DAS CACHE
Responsive
and
high-‐performing
Oracle
database
applications,
required
for
smooth
business
operations,
demand
high
I/O
throughput
from
storage.
This
means
that
companies
who
run
these
applications
need
powerful
servers
with
a
range
of
options
for
upgrading
storage.
Additionally,
the
balance
of
storage
and
compute
performance
determines
database
system
performance.
Knowing
that
storage
speed
and
technology
is
key,
Dell
designed
the
new
four-‐socket
PowerEdge
R930
server
with
extremely
fast
storage
technology
in
mind
to
deliver
outstanding
performance.
In
the
Principled
Technologies
labs,
we
tested
a
Dell
PowerEdge
R930
server
running
Oracle
Database
12c
with
an
OLTP
workload.
We
tested
the
server
with
three
storage
configurations:
an
all-‐hard
disk
drive
(HDD)
configuration,
a
hybrid
configuration
using
a
mix
of
HDDs
and
SAS
SSDs
using
SanDisk
DAS
Cache
caching
solution
offered
by
Dell,
and
an
all-‐PCIe
SSD
configuration
using
SanDisk
DAS
Cache.
The
storage
upgrade
options
of
the
Dell
PowerEdge
R930
showed
exceptional
scalability
to
meet
current
and
future
business
demands,
delivering
up
to
11.1
times
the
already
excellent
performance
of
the
base
configuration.
If
you
are
looking
for
a
powerful
new
server
to
run
your
Oracle
database
infrastructure,
consider
the
new
Dell
PowerEdge
R930

The
benefits
of
upgrading

PCIe
storage
using
SanDisk
DAS
Cache
UPGRADE STORAGE TO INCREASE PERFORMANCE
The
Dell
PowerEdge
R930
is
designed
to
handle
demanding,
mission-‐critical
workloads
such
as
enterprise
resource
planning
(ERP),
e-‐commerce,
large-‐scale
virtualization,
and
very
large
databases.
Its
standard
chassis
configuration
has
twenty-‐
four
2.5-‐inch
drive
bays.
Additionally,
Dell
offers
a
front-‐loading
PCIe
SSD
chassis
with
sixteen
2.5-‐inch
drive
bays
and
eight
2.5-‐inch
PCIe
SSD
drive
bays.
We
tested
both
server
chassis
designs
using
four
different
storage
configurations
for
the
Oracle
database
files:1
All-‐HDD configuration:
22
SAS
HDDs
(a
standard
chassis
configuration
with
twenty-‐four
2.5-‐inch
drive
bays)
Hybrid HDD and SSD configuration using SanDisk DAS Cache:
10
SAS
HDDs
and
12
SAS
SSDs
(a
standard
chassis
configuration
with
twenty-‐
four
2.5-‐inch
drive
bays)
PCIe SSD configuration using SanDisk DAS Cache:
eight
PCIe
SSDs
(PCIe
SSD
chassis
with
sixteen
2.5-‐inch
drive
bays
and
eight
2.5-‐inch
PCIe
SSD
drive
bays)
While
hard
drives
offer
the
advantages
of
large
capacity
and
affordability,
they
may
not
be
able
to
generate
sufficient
random
I/O
throughput
and
IOPs
to
keep
up
with
business
demands
when
workloads
experience
a
high
level
of
transactional,
random
I/O
activity.
SSDs,
whether
stand-‐alone
or
used
as
part
of
a
caching
solution,
can
provide
that
next
level
of
I/O
performance
for
intensive
database
workloads.
SANDISK DAS CACHE ACCELERATES YOUR APPLICATIONS
Dell
PowerEdge
R930
configurations
using
SSDs
can
benefit
from
further
application
performance
acceleration
by
adding
SanDisk
DAS
Cache,
a
server-‐level
caching
solution
for
direct-‐attached
storage,
brought
to
you
by
Dell.
This
software
can
accelerate
the
speed
of
storage
input-‐output
(I/O)
operations,
enabling
substantial
performance
increases
of
I/O-‐intensive
applications,
including
database
applications
and
workloads
such
as
OLTP,
OLAP,
HPC,
and
Business
Analytics.
In
many
cases,
database
applications
actively
use
only
a
portion
of
the
full
dataset;
we
refer
to
this
subset
as
the
“hot”
data.
SanDisk
DAS
Cache
leverages
SSDs
of
any
type—PCIe,
NVMe,
SAS,
or
SATA—in
the
host
server
to
create
a
read-‐write
cache
for
the
most
frequently
accessed
or
hot
data.
SanDisk
DAS
Cache
software
works
with
the
application
to
identify
this
hot
I/O
targeted
for
back-‐end
storage
and
acceleration.
Once
configured,
all
the
writes
of
the
application
are
committed
at
the
cache
layer
made
up
of
SSDs
and
all
re-‐reads
are
from
the
same
cache.
This
design
not
only
has
the
potential
to
dramatically
boost
heavy
I/O
application
performance
but
also
helps
you
optimize

OUR TEST APPROACH AND FINDINGS
While
an
all-‐HDD
configuration
can
deliver
excellent
Oracle
database
performance,
the
Dell
PowerEdge
R930
provides
multiple
chassis
options
and
storage
upgrades
that
can
greatly
increase
its
I/O
capabilities.
To
test
this,
we
configured
and
ran
a
heavy
OLTP
workload
on
each
storage
configuration.
(For
more
details
on
the
server
configuration,
see
Appendix
A.
For
the
specifics
of
our
testing,
see
Appendix
B.)
Figure
1
shows
the
relative
Oracle
database
performance
of
the
three
configurations
we
tested.
We
normalized
performance
to
the
all-‐HDD
configuration
because
Oracle
does
not
permit
publishing
specific
benchmark
results.
As
Figure
1
shows,
replacing
all
of
the
HDDs
with
the
hybrid
configuration,
using
a
mix
of
HDDs
and
SSDs
with
SanDisk
DAS
Cache,
delivered
9.5
times
the
database
performance
of
the
base
configuration.
The
third
configuration
we
tested,
using
eight
PCIe
SSDs
with
SanDisk
DAS
Cache,
delivered
the
greatest
performance
increase—11.1
times
the
performance
of
the
all-‐HDD
configuration.
Figure 1: With eight
PCIe SSDs and
SanDisk DAS Cache,
the Dell PowerEdge
R930 supported 11.1
times the
performance of the
all-‐HDD
configuration.

is
essential
to
companies
running
Oracle
Database.
The
new
Dell
PowerEdge
R930
provided
strong
performance
with
22
SAS
HDDs,
but
this
performance
improved
when
we
used
a
mix
of
HDDs
and
SDDs
along
with
SanDisk
DAS
Cache.
We
saw
the
greatest
performance
boost
when
we
used
eight
PCIe
SSDs
with
SanDisk
DAS
Cache.
The
upgraded
configuration
of
the
Dell
PowerEdge

with
PCIe
SSDs
and
SanDisk

delivered
11.1
times
the

configuration.
This
makes
the
new
Dell
PowerEdge
R930
a
powerful
platform
with
scalable
storage
options
that
can
potentially
translate
into
significant
service
improvements
for
your
business
and
your
customers,
which
helps
in
maximizing
ROI.

APPENDIX B–DETAILED TEST METHODOLOGY
About our test tools
HammerDB
HammerDB
is
an
open-‐source
benchmark
tool
that
tests
the
database
performance
of
many
leading
databases,
including
Oracle
Database,
Microsoft®
SQL
Server®,
PostgreSQL,
MySQL™,
and
more.
The
benchmark
includes
two
built-‐
in
workloads
derived
from
industry-‐standard
benchmarks:
a
transactional
(OLTP
workload
derived
from
TPC-‐C)
workload
and
a
data
warehouse
(workload
derived
from
TPC-‐H)
workload.
For
this
study,
we
used
the
transactional
workload.
This
transactional
workload
is
derived
from
TPC-‐C,
and
as
such
is
not
comparable
to
published
TPC-‐C
results.

more
information
about
HammerDB,

hammerora.sourceforge.net.
Configuring disk drives
We
designed
each
configuration
to
provide
the
best
possible
performance
while
staying
as
close
as
possible
to
the
Oracle
best
practices
guide.
We
used
two
different
servers
for
the
test.
For
the
all-‐HDD
and
hybrid
drive
with
DAS
Cache
configurations,
we
used
a
Dell
PowerEdge
R930
with
24
SAS
hard
drive
bays.
For
the
PCIe
SSD
configuration,
we
used
a
Dell
PowerEdge
R930
with
16
SAS
hard
drive
bays
and
eight
PCIe
SSD
bays.
We
configured
both
servers
identically
except
for
the
hard
drive
bays.
We
provide
the
details
of
each
configuration
below.
All-‐HDD configuration
We
used
two
900
GB
10,000
RPM
SAS
hard
drives
configured
in
a
RAID
1
to
hold
the
OS.
We
used
22
300GB
15,000
RPM
SAS
for
database
and
logs.
We
configured
the
22
hard
drives
in
11
RAID
1
with
write
back
policy.
We
used
10
of
the
RAID
1
for
the
database
and
one
RAID
1
for
the
logs.
Hybrid configuration with SanDisk DAS Cache
We
used
two
900
GB
10,000

Installing Oracle Grid Infrastructure for Standalone Server 12c
In
all
test
configurations,
we
used
Oracle’s
recommended
approach
to
managing
storage,
Automatic
Storage
Management
(ASM).
On
each
configuration,
we
configured
the
underlying
storage
for
redundancy,
as
would
be
required
in
nearly
all
environments.
Oracle
ASM
provides
three
redundancy
levels:
Normal
for
two-‐way
mirroring,
High
for
three-‐
way
mirroring,
and
External,
which
provides
no
mirroring
but
uses
redundancy
via
hardware
RAID
controllers.
On
the
HDD
and
DAS
Cache
configurations,
which
had
a
Dell
PowerEdge
RAID
Controller
(PERC)
H730P,
we
used
RAID
1
disk
groups,
presented
those
to
Oracle
ASM,
and
used
External
redundancy.
On
the
PCIe
SSD
configuration,
the
SSD
devices
used
no
RAID
controller,
so
we
used
Oracle
ASM
Normal
redundancy
for
two-‐way
mirroring.
Prior
to
starting
the
steps
below,
we
downloaded
the
Oracle
12
Grid
installation
and
extracted
it
to
the
/home/grid
directory.
1. Run
the
GUI
installer
for
Oracle
Database
using
the
following
commands:
ssh –Y oracle@R920_IP_address
grid_env
cd /home/grid
./runInstaller
2. Launch
the
Oracle

installation
wizard.
3. In

and
click
Next.
4. In

Options,
select

and
Configure

and
click
Next.
5. In

select
English
and
click
the
right-‐pointing
arrow
between
the
two
selection
panels
to
add
English
to
the
Selected

panel.
Click
Next.
6. In
Create

click
Change
Discovery

7. Enter
/dev/oracleasm/*
for
the
Disk

Path,
and
click
OK.
(We
left
the
default
path
for
SAS
configuration.)
8. Check
the
boxes
for
all
drives,
and
Click
Next.
(We
did
not
select
the
last

We
configured
the
