The document discusses applying Open Compute Project (OCP) rack and power specifications to new and existing data centers. It outlines key changes the OCP made from traditional specifications, such as increasing rack width from 19" to 21" and separating servers, storage, and power onto different shelves. It also discusses considerations for higher power densities, input voltages, and output voltages when applying OCP specifications.

Replacing Oracle CDC with Oracle GoldenGateStewart Bryson
The Oracle documentation states that Oracle Change Data Capture (CDC) will be de-supported in the future and replaced with Oracle GoldenGate (OGG). So are we justified in assuming that OGG provides all the necessary features to actually replace CDC?
In this presentation, we will examine CDC and it's application in real-time BI solutions and data warehouses. We will also have a look at the feature set of OGG and decide whether it is a suitable replacement for CDC for all of these applications. When gaps in the product are identified -- such as lack of support for subscription groups -- we will see techniques that can be used to bridge those gaps without sacrificing the performance and scalability of OGG.
We cover the IBM solution for HPC. In addition to hardware and software stack we show how the rational choice of compilation/running parameters helps to significantly improve the performance of technical computing applications.
OLTP with Dell EqualLogic hybrid arrays: A comparative study with an industry...Principled Technologies
The effectiveness of your OLTP database environment can depend to an enormous degree on the storage system you select. We compared a database server solution using the Dell EqualLogic PS6210XS with a one using competing industry-leading SAN storage.
The EqualLogic PS6210XS solution was overwhelmingly superior in all areas we tested. It delivered twice the performance with half the response time, and used a fraction of the power.
These factors make it clear that any business that relies on its database servers and wants to get the greatest return on its storage investment must consider the Dell EqualLogic PS6210XS.

Effective power management is quickly becoming a major concern for data centers of all sizes. Specialized power management software is now available to help meet these needs. We tested two of these power management tools, Dell OpenManage Power Center and JouleX Energy Manager for Data Centers.
Both Dell OpenManage Power Center 2.0 and JouleX Energy Manager address some of the most common critical power tasks for your data center servers. JouleX Energy Manager is a product that includes additional features, but you must pay upfront acquisition costs and incur recurring software maintenance costs for potentially less-common features that just a subset of IT departments may implement. In contrast, Dell OpenManage Power Center, when used in conjunction with iDRAC Enterprise, comes at a very compelling price point – $0.00. This translates to a great value and an immediate return on investment.
The building of Internet data centers (IDCs) is a growing industry that is pushing the limits of electric power and reliability requirements. As utilities must decide whether it is worth the cost to build new infrastructure to keep up with the present demand, facility operators are looking at power distribution designs that will improve efficiency and allow them to continue to expand their operations.
Improving Oracle Database performance: Moving from older servers to 16th Gene...Principled Technologies
Bare metal Dell PowerEdge R960 servers running Oracle Enterprise Linux 8.8 handled more Oracle Database 19c transactions than legacy PowerEdge R940 and R920 virtualized solutions running Windows Server 2019
Conclusion
Upgrading to latest-gen servers could be a performance boon for your business-critical applications. In addition to the better transactional database performance that newer servers typically deliver, switching from virtualization to bare metal for Oracle Database could increase that performance gain. We found that the latest-gen Dell PowerEdge R960 powered by 4th Gen Intel Xeon Scalable processors processed up to 7.9 times the Oracle Database 19c transactions per minute that the legacy PowerEdge R920 server handled and up to 2.4 times the TPM the PowerEdge 940 produced. With those levels of improvement, organizations using Oracle Database for ecommerce or inventory workloads could grow their user base, generate more revenue, or improve inventory control.
In addition, data center architects and others could appreciate the space saving that comes from consolidating workloads from the new server upgrade. Our results show that the bare metal PowerEdge R960 server delivered 7.9 times the TPM per rack unit than the legacy PowerEdge R920 virtualized solution and 1.8 times the TPM per rack unit than the legacy PowerEdge R940 virtualized solution. Based on this performance-per-rack unit ratio, organizations potentially could consolidate the work of seven PowerEdge R920 servers or two legacy PowerEdge R940 servers to just one Dell PowerEdge R960.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Bel Power Solutions: Applying Open Compute Rack (OCP) & Power Specifications to New & Existing Data Centers (Jan. 2018)

Applying Open Compute Rack
and Power Specifications to
New and Existing Data Centers

2. APPLYING OPEN COMPUTE RACK AND POWER SPECIFICATIONS
TO NEW AND EXISTING DATA CENTERS
When Facebook and others launched the Open Compute Project (OCP) in 2011, the goal was to accelerate the
commercialization of hardware designs that enable greater data center efficiency and flexibility. Since then, the
OCP has gained traction in the market, growing into an influential community focused on open data center hardware.
Among the major developments in the last several years are the addition of notable members, including Apple,
Cisco, Nokia and Google; continued growth in the number and maturity of OCP specifications; and the development
of specifications for telecommunication data centers.
From its beginning, the OCP has questioned and reconsidered traditional approaches to data center design,
challenging the idea that we should continue doing things because that is the way they have always been done.
That’s great if you’re just building out your computing infrastructure, as several of the key players in OCP are, but
it can create challenges for organizations with significant investments in legacy infrastructure. Fortunately, as the
community has grown, OCP specifications have expanded to increase their applicability in legacy environments.
This is causing data center operators across the spectrum to take notice. They are increasingly evaluating the
viability of OCP specifications when building new data centers or expanding existing facilities. They often find
opportunities to drive down costs and improve efficiency, but also face some key decisions on how best to apply
the specifications—or the principles behind the specifications—to their particular environment and objectives.
The Changing Shape of Equipment Racks
One of the shifts the OCP made from conventional data center
standards in its initial Rack and Power specification was to redefine
the dimensions of the IT equipment rack from the traditional 19-inch
to 21-inch wide racks.
The 19-inch rack, according to the OCP, didn’t provide enough space
to accommodate the airflow and serviceability requirements of today’s
IT equipment. Adding two inches to the width of the rack creates
more room for cable runs, simplifies server deployment and service,
and improves airflow to create opportunities for more efficient data
center cooling. Facebook has standardized on the 21-inch rack in their
data centers and this has led to the commercialization of racks and
supporting products that comply with the 21-inch specification.
The OCP Rack and Power specification, of course, went beyond rack
dimensions. The specification essentially unbundles the traditional
server configuration, deploying servers, storage and power on
separate trays within the rack. With these components physically
separated, servers can be upgraded more cost-effectively when
new processors are introduced. It also provides greater flexibility in
configuring racks with required equipment.

APPLYING OPEN COMPUTE RACK AND POWER SPECIFICATIONS
TO NEW AND EXISTING DATA CENTERS
These benefits were compelling enough to cause OCP members who weren’t ready to abandon their 19-inch racks
to apply the principles of the Rack and Power specification to EIA-compliant 19-inch racks. Now, designers and
operators seeking to leverage the benefits of the OCP specification can choose between 19-inch and 21-inch racks,
with a full complement of racks, servers, storage and power products available for each.
Accommodating Higher Density
The OCP specifications were driven by the needs of large-scale deployments, mostly greenfield data centers built
in areas where real estate costs are low. In these environments, capacity can be easily spread out and there isn’t a
good economic case for high-density racks.
As a result, the OCP specification supports 13.2 kW of IT equipment within the rack. This is accomplished through the
use of two power shelves within the rack, each of which consists of three power supplies in an N + 1 configuration.
Each shelf supports a different zone within the rack and is connected to the rack management controller or facility-
level monitoring to collect data on temperature, power in, power out, and utilization. Power shelves can also include
“smart boxes” which archive data in the event of a failure for diagnostics.
While there generally isn’t room within the rack for additional power shelves, you can accommodate higher densities
within the OCP rack by choosing a power shelf designed for high density. Shelves are available that include six 3 kW
power supplies in an N + 1 configuration that uses just 1U of rack space. This effectively doubles the power capacity
of an OCP rack.
Due to the efficiency curve of modern power supplies, these higher density shelves can be deployed without
compromising efficiency, even if the initial capacity of the rack is well below the design specification. The power
supplies have a maximally flat efficiency curve across the load range.
The efficiency curves also highlight the differences between Platinum and Titanium power supplies. Data centers
striving to achieve the highest levels of efficiency will be tempted to specify Titanium power supplies. However, it’s
useful to evaluate the efficiency curves
in light of your expected requirements
before making a final decision. While
Titanium power supplies provide
efficiency improvements at certain
points of the curve, the efficiency of
Platinum power supplies may provide
improvements at other points, such as
light and full loading. Comparing the
performance of each at the points on
the curve you plan to operate can help
guide decisions around whether the
additional cost of a Titanium power
supply is warranted by the efficiency
gains that will be realized.

The Question of Voltage
One of the challenges designers now face in configuring data center power is making decisions about input voltage to
the rack and output voltage from the power shelf to the servers. In the past, 208 V to the rack and 12 V to the server
were common, but as designers seek to minimize losses within the critical power path created by distribution,
conversions and step-downs, alternate approaches are being considered.
The OCP specification addresses this by bringing 277/480 V power (230/400 V in Europe) directly from the transformer
to the rack, eliminating the stepdown to 208 V. This can create a 2.5 percent efficiency improvement compared to
208 V without making significant changes to the way power is delivered to the rack.
Some designers see an opportunity to go even further. Why not, they ask, simply rectify the 480 V power coming
into the data center and deliver 380 V DC to the rack? This saves an additional 1 to 2 percent compared to the OCP
specification, but there is resistance among operators to running high-voltage DC in the data center. In addition,
equipment such as fans may still require AC power, creating complications. Still, the efficiency of DC power is
appealing and it would not be surprising if this approach finds more proponents in the future. The power shelves
used in an OCP rack can be configured to accommodate 208 V AC, 277 V AC or 380 V DC.
Output voltages can also vary. The initial OCP specification provided for 12 V output from the power shelf, which
is what most server hardware is designed to accept. But when Google joined the OCP in 2015, they developed an
OCP specification for 48 V output from the power shelf. Google is a proponent of 48 V servers for the same reason
the OCP opted to deliver higher voltages to the rack—the higher the voltage, the greater the efficiency.
In this case, delivering 48 V to the server reduces the voltage drop across the busbar and connectors by a factor
of 16 (assuming same conductor cross section), increasing the overall efficiency compared to 12 V. The bigger
advantage of 48 V, however, is that it provides a path to the future for racks with much higher power requirements.
This cannot be easily realized with 12 V distribution because of the higher currents required.
Until Google joined the OCP, the only servers that could accept 48 V input were those manufactured for Google.
It’s still too early to determine whether the OCP 48 V specification will drive broad commercialization of 48 V servers,
but the initial signs are promising. If you’re seeking to achieve the highest possible efficiency and are willing to live
with the limits of the current market for 48 V servers, this could be a viable option that is supported by the current
generation of power shelves.
A further variation comes into play as telecommunication companies transition to data centers. Telco providers have
a long history with -48 V input equipment. As they shift from central offices with purpose-built hardware to data
centers with standardized hardware and software-defined services, they will increasingly replace their specialized
equipment with servers running at 12 V with an intermediate -48 V to 12 V DC/DC shelves. In future, they may migrate
to servers directly supplied with 48 V.

APPLYING OPEN COMPUTE RACK AND POWER SPECIFICATIONS
TO NEW AND EXISTING DATA CENTERS
Making the Move to ocp
As the OCP specifications continue to mature, they are being applied to a wider range of environments and
requirements. With a mission of improving the efficiency and flexibility of data center hardware, the OCP is helping
advance new approaches to data center design that have broad benefits within the industry. While not everybody
is well positioned to adopt the OCP specifications, data center designers and developers should, at minimum,
stay abreast of the developments within the OCP and how they are shaping the future of data center hardware.
