2 New Potential for Business Intelligence from Hitachi and SAP
Every business must make decisions based on operational data, from a retail chain optimizing
inventories and pricing to a utility company managing supply and consumption against past usage and
weather conditions. Unfortunately, the very large data sets needed to make informed business decisions
accurately and confidently are often beyond the capabilities of conventional BI infrastructures to handle
in a timely manner.
Because data analysis has typically required long-running processes, it has traditionally been conducted
in batches, often at night, generating static reports established by IT departments. Based on those
limited, inflexible reports, business users track results against past projections and make plans for the
immediate future.
The value of analyzing data hours or even days after it is collected is necessarily limited by the
“freshness” of the data. In the time between when data is generated and decision makers are able to
respond to it, the business situation might have changed completely. Therefore, there was typically
significant risk under that scenario that adjustments to business operations would actually take the
business in the wrong direction.
Businesses have attempted to address these shortcomings by shortening the time between data
collection and analysis. Often, decision support is accelerated by simplifying analytical models or
reducing the amount of data they use. While that approach can clearly generate results more quickly,
speed comes at additional cost in terms of accuracy and depth, which can impose an unwelcome level of
compromise into the BI process.
SAP HANA appliance software and Hitachi Unified Compute Platform Select for SAP HANA resolve key BI
limitations. In-memory computing enables the SAP HANA platform to hold a complete copy of data in
the system main memory, removing latency associated with copying data to and from system hard disks.
Together with other software performance innovations and the processing power of the Hitachi
hardware platform, this capability enables the solution to perform instantaneous data calculations,
driving up the value of business data to overall success. Hitachi and SAP offer joint expertise and
integration that helps drive successful implementation of the real-time BI solution:
? Agility and integration. Systems are engineered to come online transparently, readily
interoperate with the existing IT environment, and provide a single point of access to previously
isolated data silos.
? Robustness and innovation. The solution provides high performance for real-time data analysis
and reporting, mission-critical dependability, and flexibility to meet new challenges.
? Scalability and investment protection. The infrastructure allows easy expansion of processing
and storage, exceptional ROI to satisfy demanding cost constraints, and a non-disruptive
upgrade path for technology refresh.
Self-service, ad-hoc reporting by business users across company roles provides an efficient means to
increase the value of data by getting it into the hands of those who need it in real time. BI dashboards
can drive value up even further, allowing business users to create the data views most relevant to their
needs and keeping those views up to date with refreshed data as it emerges.

5 Use Case Studies for Next-Generation Business Intelligence
The potential BI successes enabled by SAP HANA appliance software deployed on Hitachi Unified
Compute Platform Select for SAP HANA are tremendously varied. The brief use case studies in this
section illustrate by way of example a few such implementations.
5.1 Use Case: Evolving to a Market-Responsive Supply Chain
Consumer products companies exemplify the drive in many business segments to modernize the supply
chain by better aligning it with ongoing market responses. SAP HANA appliance software running on
Hitachi Unified Compute Platform Select for SAP HANA gives those businesses an excellent opportunity
to perform real-time analysis of massive amounts of supply-chain data from both inside and outside the
company.
In the former “push” model, companies focused almost entirely on the supply side of the marketplace,
seeking to reduce costs and grow distribution networks. Little if any attention was paid to developing
insight about consumer behavior, which created disconnects, for example, between sales and marketing
initiatives on one hand and production operations on the other.
Over the past several years, businesses have increasingly come to recognize the value of visualizing the
supply chain from the consumer perspective. A supply network driven by a “pull” model captures
demand signals and uses them in conjunction with planning data to improve business decisions in
support of the company’s overall financial goals.
Make Better Decisions Faster with Real-Time Intelligence; Page 6 of 11
The Demand Signal Repository (DSR) is a database-driven approach to collecting and integrating data
from throughout the value chain, from the retail point of sale to the corporate planning office, to
improve business decisions. The overall value of the market-responsive business model enabled by DSR
capabilities depends on timely and ongoing adjustment to the supply chain based on patterns detected
in the relationships between planning and response data.
SAP HANA appliance software running on Hitachi Unified Compute Platform Select for SAP HANA gives
forward-looking companies the ability to make sophisticated responses to demand signals in real time.
That gives strategic planning, sales, marketing, manufacturing, and other business functions the benefit
of BI mechanisms that mine the DSR and generate instantaneous business insights to fine-tune the
supply chain and refine planning using predictive analytics.
Real-time analytics enabled by the SAP HANA appliance software deployed on Hitachi Unified Compute
Platform Select for SAP HANA can help consumer products companies better align market responses
with the supply chain. Examples of how the solution improves specific business functions include the
following:
? Product development is better informed by customer demand.
? Pricing and trade promotions are tuned on an ongoing basis based on consumer responses.
? Order fulfillment achieves higher service levels using adjustments based on daily, in-store
analysis.
Dramatic improvements to profitability are possible by continuously updating supply chain operations
based on consumer behavior. SAP HANA appliance software and Hitachi Unified Compute Platform
Select for SAP HANA are the basis for high-performance, cost-effective, highly available infrastructure to
support those initiatives. As a result, companies stand to benefit from lower inventory, avoiding out-of-
stock conditions that interfere with sales, and reducing supply chain costs.
5.2 Use Case: Optimizing Trade Promotion Effectiveness
Measuring and increasing the success of their trade promotions is an ongoing challenge faced by many
companies. Many invest significant resources and effort toward attempting to align their pricing with
promotion-related field data from point-of-sale locations. The relationships between the two are often
very difficult to determine with any accuracy, because business analysts lack the means to apply formal
analytical models to the unstructured data involved.
As a result, judgments about where and how to apply trade promotions may be made on the basis of
intuition instead of hard data. In such circumstances, the impacts on sales levels and profitability that
result from those judgments are typically also not measurable. By leaving the investments a company
makes in this area somewhat to chance, that lack of metrics has a net negative effect on profitability,
even if many of the intuitive choices made appear to be successful.
Conventional BI approaches to adding structure to those circumstances may well be quite effective, in
terms of aligning the internal and external data. It may be possible to make trade promotions more
effective, while also measuring how specific decisions impact overall results. BI may make it possible to
calculate key metrics across multiple dimensions, allowing more sophisticated use of sales data.
On the other hand, under a typical BI scenario, significant time and effort may be needed to harmonize
internal and external data so that it can be directly consumed by the algorithms that drive conclusions.
Because of performance limitations, it would also be necessary to aggregate the data for batch
Make Better Decisions Faster with Real-Time Intelligence; Page 7 of 11
processing, leading to the timeliness limitations discussed elsewhere in this paper. In short, applying BI
mechanisms to our hypothetical trade-promotion scenario has a positive effect, but with significant
limitations that restrict their value.
Contrasting that state with the use of real-time analytics enabled by SAP HANA appliance software and
Hitachi Unified Compute Platform Select for SAP HANA reveals the following advantages with regard to
gauging and optimizing the effectiveness of trade promotions:
? Rapid parsing of data supports drilling down, up, or over within the data set in seconds.
? Eliminating the need for aggregation allows analysis to be conducted on an as-needed basis.
? Very responsive ad-hoc analytics put power to fine-tune promotions in the hands of users.
5.3 Use Case: Analyzing the Impact of Commodity Pricing on Profitability
For many companies, a coherent view of past, present, or future profitability requires an understanding
of how fluctuations in the cost of key commodities impact financial operations as a whole. That is true
whether the commodities are used as raw material for manufacturing operations, such as the impact of
grain prices on a processed-foods manufacturer, but it is also more generally true for other materials
required for business operations, such as fuel.
As commodity prices rise, they place upward pressure on the cost of doing business. As competitive
pressures increase and have the tendency to push down gross revenues, fluctuations in commodity
prices become more critical. In both cases, responsive profitability analysis is vital to maintaining
profitability.
Unfortunately, traditional models have relied on static reports that may already be stale by the time
they are created, and which certainly don’t have the ability to remain current on an ongoing basis. The
views enabled by these approaches are also typically limited to profit and loss data, creating an over-
simplified point of view that fails to provide multi-dimensional insights about where and when to adjust
pricing.
Conventional BI solutions add sophistication in the form of multi-dimensional profitability analysis that
can better accommodate factors such as competitor behavior, time of year, and geography. By looking
outside the scope of profit and loss data, applying BI can enhance business analysts’ ability to
understand the effects of commodity pricing. This approach is likely to be limited, however, by
limitations in terms of ad hoc analysis and the need to aggregate data for offline analysis, due to
performance limitations.
Similar to the above use cases, the use of real-time BI and analytics using SAP HANA appliance software
on Hitachi Unified Compute Platform Select for SAP HANA can add value to the undertaking, with
positive net impacts on operations that may boost profitability:
? Ad-hoc bill of materials analysis shows the impact of rising commodity prices on margins
? Eliminating the need for aggregation allows analysis to be conducted on an as-needed basis.
? Insight about pricing impact establishes how best to respond to commodity price fluctuations.
6 In-Memory Database Innovation from SAP HANA Appliance Software
The SAP HANA platform was designed specifically to deliver instantaneous business insight from
extremely large data sets. As the use cases above demonstrate, this ability can help companies maintain
Make Better Decisions Faster with Real-Time Intelligence; Page 8 of 11
or drive up profitability in the face of changing business conditions. In addition to seeing the impact of
internal and external factors, SAP HANA appliance software also provides rich functionality to conduct
hypothetical “what if” analysis to make informed estimates of the effects of various actions.
Organizations that deploy SAP HANA appliance software on Hitachi Unified Compute Platform Select for
SAP HANA achieve outstanding performance and scalability that enable users to create sophisticated ad
hoc reports. Putting that power into business users’ hands helps the positive effects of business
intelligence become pervasive throughout the organization, as individuals begin to seek more
substantial rationale for their actions. Data mining and modeling need no longer be a complex activity
that requires involvement from IT; with the SAP HANA platform, the average business users can come to
regard those functions in much the same way they do the desktop productivity software they use every
day.
Forecasting, planning, and evaluation functions are enabled by the SAP HANA platform’s ability to access
data from multiple sources (even those that have traditionally been incompatible with one another) and
rapidly draw ad hoc conclusions from it. Importantly, this functionality does not require changes to any
existing applications or infrastructures. Core components of the SAP HANA platform include the
following:
? In-memory database that works in conjunction with a powerful data calculation engine
? Real-time replication service to access and replicate data in the SAP ERP application
? Data integration services to access and index information from virtually any data source
As mentioned elsewhere in this paper, the in-memory database at the heart of the SAP HANA platform
avoids disk latency by keeping an entire copy of business data in live system memory. Other innovations
complement that approach, such as the ability to optimize efficiency by storing data in either row or
columnar order, which can provide significant benefit to throughput and compression performance.
7 Accelerated Infrastructure for Business: Hitachi Unified Compute Platform Select for
SAP HANA
Real-time BI with SAP HANA appliance software places significant demands on the host system,
including large memory capacity to contain large data sets in system memory, the processing power to
manipulate that data, and sufficient internal system I/O to efficiently move the data between the
memory, cache, and processing pipeline. Hitachi Unified Compute Platform Select for SAP HANA is
ideally suited to those requirements.
7.1 Hitachi Compute Blade 2000
The processing engine behind Hitachi Unified Compute Platform Select for SAP HANA is Hitachi Compute
Blade 2000, an enterprise-class blade server platform equipped with two Intel Xeon processors E7 family
per blade. These systems are designed to deliver outstanding, enterprise-class performance and
scalability, with mission-critical reliability, while also being highly cost-effective, in terms of both capital
and operating expense.

Hitachi symmetric multiprocessing (SMP) technology enables multiple server blade resources to act as a
single server to meet the performance requirements of the SAP HANA appliance software. SAP HANA
appliance software log volume in the platform is processed on multi-level cell solid state storage devices
to improve application response times with a persistent, high-performance, high-capacity memory tier.
The system’s inherent scalability provides investment protection, with the flexibility to increase
aggregated processing capability and memory expansion. This characteristic helps protect against the
need for forklift upgrades as a result of growing business demands through the increase and utilization
of processor cores, I/O slots, memory, and other components.
Hitachi Compute Blade 2000 reduces the risk of unplanned downtime of the SAP HANA platform with its
sophisticated, built-in reliability, availability and serviceability (RAS) features. For reliability, the chassis is
fully redundant, including two management modules for redundancy. Each module supports an
independent management LAN interface from the data network for remote and secure management of
the chassis, and blades and components are hot swappable.
Additional redundant components include a highly reliable backplane and I/O, as well as fully redundant
power supply modules. The platform also supports live firmware updates without shutting down the
blades. In case of a hardware failure, the system automatically detects the fault and identifies the
problem by indicating the faulty module, allowing immediate failure recovery; support for SNMP and
alerts by email are also included.
Some key features and benefits of these systems are summarized in Table 1.

3 Customer Success, Powered by Proven Partnership
A long-standing partnership between Hitachi and SAP complements each company’s individual industry-
leading expertise. Work by the two companies on real-time BI began in the lab long before it emerged
into customer data centers. Software and hardware engineers built test beds to establish the optimal
set of components to deliver state-of-the-art performance, scalability, and reliability. This effort resulted
in an integrated, comprehensive solution stack that is pre-certified by the two companies, which
streamlines implementation while also ensuring optimal results.

5 Use Case Studies for Next-Generation Business Intelligence
The potential BI successes enabled by SAP HANA appliance software deployed on Hitachi Unified
Compute Platform Select for SAP HANA are tremendously varied. The brief use case studies in this
section illustrate by way of example a few such implementations.
5.1 Use Case: Evolving to a Market-Responsive Supply Chain
Consumer products companies exemplify the drive in many business segments to modernize the supply
chain by better aligning it with ongoing market responses. SAP HANA appliance software running on
Hitachi Unified Compute Platform Select for SAP HANA gives those businesses an excellent opportunity
to perform real-time analysis of massive amounts of supply-chain data from both inside and outside the
company.
In the former “push” model, companies focused almost entirely on the supply side of the marketplace,
seeking to reduce costs and grow distribution networks. Little if any attention was paid to developing
insight about consumer behavior, which created disconnects, for example, between sales and marketing
initiatives on one hand and production operations on the other.
Over the past several years, businesses have increasingly come to recognize the value of visualizing the
supply chain from the consumer perspective. A supply network driven by a “pull” model captures
demand signals and uses them in conjunction with planning data to improve business decisions in
support of the company’s overall financial goals.
Make Better Decisions Faster with Real-Time Intelligence; Page 6 of 11
The Demand Signal Repository (DSR) is a database-driven approach to collecting and integrating data
from throughout the value chain, from the retail point of sale to the corporate planning office, to
improve business decisions. The overall value of the market-responsive business model enabled by DSR
capabilities depends on timely and ongoing adjustment to the supply chain based on patterns detected
in the relationships between planning and response data.
SAP HANA appliance software running on Hitachi Unified Compute Platform Select for SAP HANA gives
forward-looking companies the ability to make sophisticated responses to demand signals in real time.
That gives strategic planning, sales, marketing, manufacturing, and other business functions the benefit
of BI mechanisms that mine the DSR and generate instantaneous business insights to fine-tune the
supply chain and refine planning using predictive analytics.
Real-time analytics enabled by the SAP HANA appliance software deployed on Hitachi Unified Compute
Platform Select for SAP HANA can help consumer products companies better align market responses
with the supply chain. Examples of how the solution improves specific business functions include the
following:
? Product development is better informed by customer demand.
? Pricing and trade promotions are tuned on an ongoing basis based on consumer responses.
? Order fulfillment achieves higher service levels using adjustments based on daily, in-store
analysis.
Dramatic improvements to profitability are possible by continuously updating supply chain operations
based on consumer behavior. SAP HANA appliance software and Hitachi Unified Compute Platform
Select for SAP HANA are the basis for high-performance, cost-effective, highly available infrastructure to
support those initiatives. As a result, companies stand to benefit from lower inventory, avoiding out-of-
stock conditions that interfere with sales, and reducing supply chain costs.
5.2 Use Case: Optimizing Trade Promotion Effectiveness
Measuring and increasing the success of their trade promotions is an ongoing challenge faced by many
companies. Many invest significant resources and effort toward attempting to align their pricing with
promotion-related field data from point-of-sale locations. The relationships between the two are often
very difficult to determine with any accuracy, because business analysts lack the means to apply formal
analytical models to the unstructured data involved.
As a result, judgments about where and how to apply trade promotions may be made on the basis of
intuition instead of hard data. In such circumstances, the impacts on sales levels and profitability that
result from those judgments are typically also not measurable. By leaving the investments a company
makes in this area somewhat to chance, that lack of metrics has a net negative effect on profitability,
even if many of the intuitive choices made appear to be successful.
Conventional BI approaches to adding structure to those circumstances may well be quite effective, in
terms of aligning the internal and external data. It may be possible to make trade promotions more
effective, while also measuring how specific decisions impact overall results. BI may make it possible to
calculate key metrics across multiple dimensions, allowing more sophisticated use of sales data.
On the other hand, under a typical BI scenario, significant time and effort may be needed to harmonize
internal and external data so that it can be directly consumed by the algorithms that drive conclusions.
Because of performance limitations, it would also be necessary to aggregate the data for batch
Make Better Decisions Faster with Real-Time Intelligence; Page 7 of 11
processing, leading to the timeliness limitations discussed elsewhere in this paper. In short, applying BI
mechanisms to our hypothetical trade-promotion scenario has a positive effect, but with significant
limitations that restrict their value.
Contrasting that state with the use of real-time analytics enabled by SAP HANA appliance software and
Hitachi Unified Compute Platform Select for SAP HANA reveals the following advantages with regard to
gauging and optimizing the effectiveness of trade promotions:
? Rapid parsing of data supports drilling down, up, or over within the data set in seconds.
? Eliminating the need for aggregation allows analysis to be conducted on an as-needed basis.
? Very responsive ad-hoc analytics put power to fine-tune promotions in the hands of users.
5.3 Use Case: Analyzing the Impact of Commodity Pricing on Profitability
For many companies, a coherent view of past, present, or future profitability requires an understanding
of how fluctuations in the cost of key commodities impact financial operations as a whole. That is true
whether the commodities are used as raw material for manufacturing operations, such as the impact of
grain prices on a processed-foods manufacturer, but it is also more generally true for other materials
required for business operations, such as fuel.
As commodity prices rise, they place upward pressure on the cost of doing business. As competitive
pressures increase and have the tendency to push down gross revenues, fluctuations in commodity
prices become more critical. In both cases, responsive profitability analysis is vital to maintaining
profitability.
Unfortunately, traditional models have relied on static reports that may already be stale by the time
they are created, and which certainly don’t have the ability to remain current on an ongoing basis. The
views enabled by these approaches are also typically limited to profit and loss data, creating an over-
simplified point of view that fails to provide multi-dimensional insights about where and when to adjust
pricing.
Conventional BI solutions add sophistication in the form of multi-dimensional profitability analysis that
can better accommodate factors such as competitor behavior, time of year, and geography. By looking
outside the scope of profit and loss data, applying BI can enhance business analysts’ ability to
understand the effects of commodity pricing. This approach is likely to be limited, however, by
limitations in terms of ad hoc analysis and the need to aggregate data for offline analysis, due to
performance limitations.
Similar to the above use cases, the use of real-time BI and analytics using SAP HANA appliance software
on Hitachi Unified Compute Platform Select for SAP HANA can add value to the undertaking, with
positive net impacts on operations that may boost profitability:
? Ad-hoc bill of materials analysis shows the impact of rising commodity prices on margins
? Eliminating the need for aggregation allows analysis to be conducted on an as-needed basis.
? Insight about pricing impact establishes how best to respond to commodity price fluctuations.
6 In-Memory Database Innovation from SAP HANA Appliance Software
The SAP HANA platform was designed specifically to deliver instantaneous business insight from
extremely large data sets. As the use cases above demonstrate, this ability can help companies maintain
Make Better Decisions Faster with Real-Time Intelligence; Page 8 of 11
or drive up profitability in the face of changing business conditions. In addition to seeing the impact of
internal and external factors, SAP HANA appliance software also provides rich functionality to conduct
hypothetical “what if” analysis to make informed estimates of the effects of various actions.
Organizations that deploy SAP HANA appliance software on Hitachi Unified Compute Platform Select for
SAP HANA achieve outstanding performance and scalability that enable users to create sophisticated ad
hoc reports. Putting that power into business users’ hands helps the positive effects of business
intelligence become pervasive throughout the organization, as individuals begin to seek more
substantial rationale for their actions. Data mining and modeling need no longer be a complex activity
that requires involvement from IT; with the SAP HANA platform, the average business users can come to
regard those functions in much the same way they do the desktop productivity software they use every
day.
Forecasting, planning, and evaluation functions are enabled by the SAP HANA platform’s ability to access
data from multiple sources (even those that have traditionally been incompatible with one another) and
rapidly draw ad hoc conclusions from it. Importantly, this functionality does not require changes to any
existing applications or infrastructures. Core components of the SAP HANA platform include the
following:
? In-memory database that works in conjunction with a powerful data calculation engine
? Real-time replication service to access and replicate data in the SAP ERP application
? Data integration services to access and index information from virtually any data source
As mentioned elsewhere in this paper, the in-memory database at the heart of the SAP HANA platform
avoids disk latency by keeping an entire copy of business data in live system memory. Other innovations
complement that approach, such as the ability to optimize efficiency by storing data in either row or
columnar order, which can provide significant benefit to throughput and compression performance.
7 Accelerated Infrastructure for Business: Hitachi Unified Compute Platform Select for
SAP HANA
Real-time BI with SAP HANA appliance software places significant demands on the host system,
including large memory capacity to contain large data sets in system memory, the processing power to
manipulate that data, and sufficient internal system I/O to efficiently move the data between the
memory, cache, and processing pipeline. Hitachi Unified Compute Platform Select for SAP HANA is
ideally suited to those requirements.
7.1 Hitachi Compute Blade 2000
The processing engine behind Hitachi Unified Compute Platform Select for SAP HANA is Hitachi Compute
Blade 2000, an enterprise-class blade server platform equipped with two Intel Xeon processors E7 family
per blade. These systems are designed to deliver outstanding, enterprise-class performance and
scalability, with mission-critical reliability, while also being highly cost-effective, in terms of both capital

appliance software log volume in the platform is processed on multi-level cell solid state storage devices
to improve application response times with a persistent, high-performance, high-capacity memory tier.
The system’s inherent scalability provides investment protection, with the flexibility to increase
aggregated processing capability and memory expansion. This characteristic helps protect against the
need for forklift upgrades as a result of growing business demands through the increase and utilization
of processor cores, I/O slots, memory, and other components.
Hitachi Compute Blade 2000 reduces the risk of unplanned downtime of the SAP HANA platform with its
sophisticated, built-in reliability, availability and serviceability (RAS) features. For reliability, the chassis is
fully redundant, including two management modules for redundancy. Each module supports an
independent management LAN interface from the data network for remote and secure management of
the chassis, and blades and components are hot swappable.
Additional redundant components include a highly reliable backplane and I/O, as well as fully redundant
power supply modules. The platform also supports live firmware updates without shutting down the
blades. In case of a hardware failure, the system automatically detects the fault and identifies the
problem by indicating the faulty module, allowing immediate failure recovery; support for SNMP and
alerts by email are also included.
Some key features and benefits of these systems are summarized in Table 1.
