applications
The Oracle Exadata Database Machine is engineered to be the
highest performing, most cost effective and most available platform
for running Oracle Database. Exadata is a modern architecture
featuring scale-out industry-standard database servers, scale-out
intelligent storage servers, state-of-the-art PCI flash storage servers
and an extremely high speed InfiniBand internal fabric that connects
all servers and storage. Unique software algorithms in Exadata
implement database intelligence in storage, PCI based flash, and
InfiniBand networking to deliver higher performance and capacity at
lower costs than other platforms. Exadata runs all types of database
workloads including Online Transaction Processing (OLTP), Data
Warehousing (DW), In-Memory Analytics and consolidation of
mixed workloads. Simple and fast to implement, the Exadata
Database Machine powers and protects your most important
databases and is the ideal foundation for a consolidated database
cloud.
Engineered System For Fast and Reliable Deployment
The Exadata Database Machine is an easy to deploy system that includes all the
hardware needed for running Oracle Database. The database servers, storage servers
and network are pre-configured, pre-tuned and pre-tested by Oracle experts,
eliminating weeks or months of effort typically required to deploy a high
performance system. Extensive end-to-end testing ensures all components work
seamlessly together and there are no performance bottlenecks or single points of
failure that can affect the complete system.
Because all Exadata Database Machines are identically
configured, customers benefit from the experience of
thousands of other users that have deployed the Exadata
Database Machine for their mission critical
applications. Customer machines are also identical to
the machines Oracle Support uses for problem
identification and resolution, and the machines Oracle
Engineering uses for development and testing of Oracle
Database. Hence, Exadata is the most thoroughly
tested and tuned platform for running Oracle
Database and is also the most supportable platform.

The Oracle Exadata Database Machine runs the standard Oracle Database.
Therefore, any application that uses the Oracle Database today can be
seamlessly migrated to use the Exadata Database Machine with no changes to
the application.
Unlike competing hardware platforms such as IBM Mainframes, Teradata, or IBM
Puredata System for Analytics (Netezza), the Exadata platform does not “lock in”
customers. These competing platforms have extensive proprietary software
interfaces that make it extremely complex and expensive to migrate applications to a
different platform. Because Exadata is based on the industry standard Oracle
database, applications can be easily and quickly migrated on or off the Exadata
platform.
Extreme System Scalability and Growth with Elastic Configurations
The Exadata Database Machine uses a scale-out architecture for both database
servers and storage servers.. As an Exadata Database Machine grows, database
CPUs, storage, and networking can be added in a
balanced fashion ensuring scalability without
bottlenecks.
The scale-out architecture accommodates any size
workload and allows seamless expansion from small
to extremely large configurations while avoiding
performance bottlenecks and single points of failure.
A high-bandwidth low-latency 40 Gb/second
InfiniBand network connects all the components
inside an Exadata Database Machine. Specialized
database networking protocols run over the InfiniBand
network and provide much lower latency and higher
bandwidth communication than is possible using
generic communication protocols. This enables both
faster response time for OLTP operations, and higher throughput for Analytic
workloads. External connectivity to the Exadata Database Machine is provided
using standard 10 Gigabit Ethernet.
Elastic configurations provide an extremely flexible and efficient mechanism to
expand computing power and/or storage capacity of any given Exadata system. The
starting configuration of an Exadata Database Machine consists of 2 database
servers and 3 storage servers, which can be further elastically expanded by adding
more database or storage severs as requirements grow.

Exadata Database Machine is the most versatile database platform. With Elastic
Configurations, the system can be custom configured to meet any business use case.
In addition to upgrading within a rack, multiple racks can be connected using the
integrated InfiniBand fabric to form even larger configurations. For example, a
system composed of four Full Racks is simply four times as powerful as a single
rack system — providing quadruple the I/O throughput, quadruple the storage
capacity, and quadruple the
processors. It can be configured as a
large single system or logically
partitioned for consolidation of
multiple databases. Scaling out is easy
with Exadata Database Machine.
Oracle Real Application Clusters
(RAC) can dynamically add more
processing power, and Automatic
Storage Management (ASM) can
dynamically add more storage.
When even larger storage capacity is required, the Oracle Exadata Storage
Expansion Rack is available. The Exadata Storage Expansion Rack enables you to
grow the Exadata storage capacity and bandwidth of any Exadata Database
Machine. It is designed for database deployments that require very large amounts of
data including: historical or archive data, backups, documents, images, XML, LOBs,
etc. The expansion rack connects to the Exadata Database Machine using the
integrated InfiniBand fabric and is extremely simple to configure, as there are no
LUNs or mount points. Storage is configured and added to a database online with a
few simple commands. The starting configuration of the Oracle Exadata Storage
Expansion Rack consists of four storage servers and can be further expanded by
adding additional storage servers.
Exadata Database Machines protect your investment by allowing newer generation
servers and storage to be deployed seamlessly into existing Exadata Database
Machines. Similarly, new software releases are compatible with previous generation
Exadata Database Machines. All currently supported Exadata platforms can be
combined in a single configuration and can run the latest Exadata software.
Extreme Performance by Offloading Data Intensive Processing
As data volumes grow exponentially, conventional storage arrays struggle to quickly
transfer data from disk and flash to database servers at a rate that keeps the CPUs
busy. Modern servers with many CPUs can consume data at many tens to hundreds
of gigabytes a second. This is far faster than conventional architectures that use
storage arrays can deliver data through their storage heads and the storage network.
The scale-out architecture of the Exadata Database Machine not only provides high
performance and scalability, it also includes a unique technology that offloads data

ORACLE DATA SHEET

intensive SQL operations into the Oracle Exadata Storage Servers. By pushing
SQL processing to the Exadata Storage Servers, data filtering and processing occurs
immediately and in parallel across all storage servers as data is read from disk and
flash. Only the rows and columns that are directly relevant to a query are sent
to the database servers.
For example, if a query is executed to identify the customers who placed sales
orders over $1000 in the month of March, an Exadata system will offload the
scanning of the table to the Exadata storage, filter out all sales orders that are less
than $1000, filter out sales orders not in March, and extract just the relevant
customer names. The result is that the data transferred to the database servers is
reduced by orders of magnitude. This greatly accelerates query execution, eliminates
bottlenecks, and significantly reduces the CPU usage of the database servers.
Each Exadata Storage Server has two Intel® Xeon® processors that are used for
database offload. A full rack Exadata Database Machine can have a total of 272
processor cores in the storage servers that can be used to offload the database
servers. The CPUs in Exadata Storage Servers do not replace database CPUs.
Instead they accelerate data intensive workloads similar to how graphics cards
accelerate image intensive workloads.
Optimizing Storage Use and I/O Through Compression
The Exadata Storage Server provides a very advanced compression capability called
Hybrid Columnar Compression (HCC) that provides dramatic reductions in
storage for large databases. Hybrid Columnar Compression enables the highest
levels of data compression and provides tremendous cost-savings and performance
improvements due to reduced I/O, especially for analytic workloads. Storage savings
is data dependent and often ranges from 5x to 20x. Typical storage savings is an
industry leading 10x. On conventional systems, enabling high data compression has
the drawback of reducing performance. Because the Exadata Database Machine is
able to offload decompression overhead into large numbers of processors in Exadata
storage, most analytics workloads run faster using Hybrid Columnar Compression
than they do without it. Hybrid Columnar Compression delivers the compression
and analytic performance benefits of column storage while avoiding the dramatic
slowdown that pure columnar stores experience for drilldown operations (single row
access).
Two modes of Hybrid Columnar Compression are available. Query optimized
compression mode is suitable for read intensive workloads such as Data
Warehouses and provides large storage savings while providing enhanced analytic
performance. Archive compression mode provides the highest degree of
compression and is targeted at seldom accessed data that is kept online.
On OLTP systems, Hybrid Columnar Compression can be used to compress older,
less active data while newer, more active and update intensive data can be
compressed using Advanced Row Compression. Oracle Database 12c provides the
ability to change the type of compression used by individual table partitions online
(even if there are global indexes on the table), to ensure seamless tiering across
different compression types as data ages and becomes less active.

Record breaking I/O Performance from Extreme Flash Storage Server
Exadata X5-2 introduces Extreme Flash Storage Servers. Each Extreme Flash
storage server contains eight 1.6 TB state-of-the-art PCI Flash drives. PCI flash
delivers ultra-high performance by placing flash memory directly on the high speed
PCI bus rather than behind slow disk controllers and directors. Exadata flash uses
the latest NVMe (Non-Volatile Memory Express) flash protocol to achieve
extremely low I/O overhead.
The Extreme Flash Storage Server replaces the previous High Performance disk
configuration of the Exadata Storage Server and is backward compatible with all
supported Exadata systems.
Sun Flash Accelerator F160 PCIe Card
Flash performance is often limited and bottlenecked by traditional storage
architectures. In contrast, Exadata uses a combination of scale-out storage,
InfiniBand networking, database offload, and PCI flash to deliver extremely high
performance rates from flash. A single full rack Exadata Database Machine X5-2,
with 8 database servers and 14 Extreme Flash storage servers can achieve up to 263
GB per second of data scan bandwidth, and up to 4.144 Million random 8K read
and write I/O operations per second (IOPS) when running database workloads.
This performance is orders of magnitude faster than traditional storage array
architectures, and is also much faster than current all-flash storage arrays. It is
important to note that these are real-world end-to-end performance figures measured
running SQL workloads with realistic I/O sizes inside a single rack Exadata system.
They are not component-level measurements based on low-level I/O tools.
Tiered Disk and Flash Delivers Cost of Disk with Performance of Flash
The second Exadata storage option is the Exadata X5-2 High Capacity Storage
Server. This server includes twelve 4 TB SAS disk drives (48 TB total) and four
Sun Flash Accelerator F160 NVMe PCIe cards with a total raw capacity of 6.4TB of
flash memory. Exadata flash in a High Capacity Storage Server can be used directly
as flash disks, but is almost always configured as a flash cache (Exadata Smart
Flash Cache) in front of disk since caching provides flash level performance for
much more data than fits directly into flash.
The Exadata Smart Flash Cache automatically caches frequently accessed data while
keeping infrequently accessed data on disk drives. This provides the performance of

ORACLE DATA SHEET
6
flash with the capacity and low cost of disk. The Exadata Smart Flash Cache
understands database workloads and knows when to avoid caching data that the
database will rarely access or is too big to fit in the cache. For example, Exadata
doesn’t cache I/Os caused by backups, table scans, or temporary results that will be
quickly deleted. In addition to automatic caching, administrators can optionally
provide SQL directives to ensure that specific tables, indexes, or partitions are
always retained in the flash cache. Tables can be retained in flash cache without the
need to move the table to different tablespaces, files or LUNs as is often required
with traditional storage. A single full rack Exadata Database Machine X5-2, with 8
database servers and 14 High Capacity storage servers can achieve up to 140 GB
per second of data scan bandwidth, and up to 4.144 Million random 8K read I/O
operations per second (IOPS) when running database workloads.
Exadata’s Smart Flash Cache is designed to deliver flash-level IO rates, and
response times for data that is many times larger than the physical flash capacity in
the machine by moving active data into flash, while leaving cold data on disk. It is
common for hit rates in the Exadata Smart Flash Cache to be over 90%, or even
98% in real-world database workloads even though flash capacity is more than 7
times smaller than disk capacity. Such high flash cache hit rates mean that Exadata
Smart Flash Cache provides an effective flash capacity that is many times times
larger than the physical flash cache. For example, a full rack Exadata Database
Machine X5-2 with 8 database servers and 14 High Capacity Storage Servers often
has an effective flash capacity equal to the full disk capacity of 672 TB.
The Exadata Smart Flash cache also caches database block writes. Write caching
eliminates disk bottlenecks in large scale OLTP and batch workloads. The flash
write capacity of a single full rack Exadata Database Machine X5-2 with 8 database
servers and 14 High Capacity Storage Servers exceeds 2.69 Million 8K write I/Os
per second. The Exadata write cache is transparent, persistent, and fully redundant.
The I/O performance of the Exadata Smart Flash Cache is comparable to dozens of
enterprise disk arrays with thousands of disk drives.
To further accelerate OLTP workloads, the Exadata Smart Flash Cache also
implements a special algorithm to reduce the latency of log write I/Os called
Exadata Smart Flash Logging. The time to commit user transactions or perform
critical updates is very sensitive to the latency of log writes. Smart Flash Logging
takes advantage of the flash memory in Exadata storage combined with the high
speed RAM memory in the Exadata disk controllers to greatly reduce the latency of
log writes and avoid the latency spikes that frequently occur in other flash solutions.
The Exadata Smart Flash Logging algorithms are unique to Exadata.
Exadata Smart Flash Cache also implements a unique algorithm to accelerate
reporting and analytical queries called Exadata Columnar Flash Cache. Columnar
Flash Caching implements a dual format architecture in Exadata flash by
automatically transforming frequently scanned Hybrid Columnar Compressed data
into a pure columnar format as it is loaded into the flash cache. Smart scans on pure
columnar data in flash run faster because they read only the selected columns,
reducing flash I/Os and storage server CPU consumption. This accelerates reporting

ORACLE DATA SHEET
7
and analytic queries while maintaining excellent performance for OLTP style single
row lookups.
Exadata uses only enterprise grade flash that is designed by the flash manufacturer
to have high endurance. Exadata is designed for mission critical workloads and
therefore does not use consumer grade flash that can potentially experience
performance degradations or fail unexpectedly after a few years of usage. The
enterprise grade flash chips used in Exadata X5 have an expected endurance of 8
years or more for typical database workloads.
The automatic data tiering between RAM, flash and disk implemented in Exadata
provides tremendous advantages over other flash-based solutions.. Many storage
vendors have recognized that the architecture of their traditional storage arrays
inherently bottleneck the performance of flash and therefore have developed new
flash-only arrays. These flash-only arrays deliver higher performance than
traditional arrays but give up the cost advantages of smart tiering of data between
disk and flash. Therefore the overall size of data that benefits from flash is limited to
the size of expensive flash. Third party flash arrays will also not benefit from
Exadata Hybrid Columnar Compression. Data deduplication provided by some flash
arrays is very effective for VDI environments but is ineffective for databases.
Exadata not only delivers much more capacity than flash-only arrays, it also delivers
better performance. Flash-only storage arrays cannot match the throughput of
Exadata's integrated and optimized architecture with full InfiniBand based scale-out,
fast PCI flash, offload of data intensive operations to storage, and algorithms that are
specifically optimized for databases.
Fault Tolerant and Fastest Database In-Memory Machine
Exadata is the ideal platform for running Oracle Database In-Memory. Oracle
Database In-Memory on Exadata does not require all data to reside in memory. Data
can be stored across multiple tiers of storage, with the hottest data in memory
providing extremely high query performance, active data on flash providing very
high I/O throughput, and less active or older data on disk at a very low cost. A single
query can access data from all three tiers: memory, flash and disk, completely
transparently. This allows Exadata to run faster, support higher capacities and
deliver lower costs than competing products.
Elastic configurations enable users to configure systems with very large system
memory. An X5-2 system can have up to 14.6 TB system memory and 19 database
servers in one single rack. In addition, the 40Gb per second InfiniBand network
provides extremely high throughput and very low latencies for in-memory queries
that are distributed across nodes.
Exadata implements Oracle Database In-Memory’s Fault Tolerant capability, a
feature that is unique to Oracle Engineered Systems. On a generic cluster
configuration, when a server node fails, the in-memory data on that node is lost, and
it takes many minutes to repopulate the in-memory data on a surviving node. During
this time analytic queries will run dramatically slower. This means generic
configurations will fail to meet business SLAs. However, when deployed on

ORACLE DATA SHEET
8
Exadata, the Fault-Tolerant feature of Oracle Database In-Memory can eliminate
this slowdown by duplicating any subset of the in-memory data across nodes. If a
node fails, queries can transparently use the duplicate copy of data on a surviving
node and processing can continue without interruption.
Enhanced Consolidation using Exadata Virtual Machines
Consolidated environments running on Exadata can now use Oracle Virtual Machine
(OVM) to deliver a high degree of isolation between workloads. This is a very
desirable feature for hosted, shared, service provider, and test/dev environments.
Using OVM, multiple software clusters can be deployed on the same Exadata
Database Machine, which enables consolidation of applications that have specific
clusterware version requirements such as SAP.
Exadata Database Machine is the world’s fastest virtualized database platform.
Exadata virtual machines use high speed InfiniBand networking with Single Root IO
Virtualization (SR-IOV) to ensure that performance within a virtual machine is
similar to Exadata’s famous raw hardware performance. Exadata Smart Scans
greatly decrease virtualization overhead compared to other platforms by
dramatically reducing message traffic to virtual machines. Exadata virtual machines
can dynamically expand or shrink CPUs and memory based on the workload
requirement of the applications running in that virtual machine.
Virtual machines on Exadata are considered Trusted Partitions and therefore
software can be licensed at the virtual machine level instead of the physical
processor level. Without Trusted Partitions, database options and other Oracle
software must be licensed at a server or cluster level even though all databases
running on that server or cluster may not require a particular option.
Enterprise-Class Security with Extreme Performance
Exadata Database Machine is the world's most secure database machine. Building
on the high security capabilities in the Oracle Database, Exadata moves decryption
processing from database server software into the Exadata Storage Server
hardware. Exadata storage leverages hardware decryption and compression
together to provide the highest performance secure databases. Encryption occurs
after the data is compressed so that the cost of decryption is decreased by the
degree of compression. By leveraging both technologies, Exadata is able to query
fully encrypted and compressed databases with near zero overhead at hundreds of
gigabytes of user data per second.
The Exadata system is designed and delivered as an integrated whole, and not a
collection of components. In traditional database deployments, the customer takes
on all the integration tasks for the system – including the task of ensuring the
security of each individual software and hardware component, and ensuring that
security is maintained across the full product stack. Oracle delivers full stack
security in the Exadata Database Machine. Exadata virtual machines provide an
added layer of isolation at the operating system level.
Exadata security has been probed and evaluated by hundreds of leading banks,
telecoms, and governments worldwide. The security findings of all these evaluations

ORACLE DATA SHEET
9
have been incorporated into the Exadata standard configuration, making it a highly
secure database system.
Mission Critical High Availability
The Exadata Database Machine is engineered to provide the highest levels of
availability. All types of failures are protected against including simple failures
such as disk, server, or network, as well as complex site failures and human errors.
Each Exadata Database Machine has completely redundant hardware including
redundant InfiniBand networking, redundant Power Distribution Units (PDU),
redundant power supplies, and redundant database and storage servers. Oracle RAC
protects against database server failure. ASM provides data mirroring to protect
against disk or storage server failures. Oracle RMAN provides extremely fast and
efficient backups to disk or tape. Oracle’s Flashback technology allows backing out
user errors at the database, table or even row level. Using Oracle Data Guard, a
second Exadata Database Machine can be configured to transparently maintain a
real-time copy of the database at a remote site to provide full protection against
primary database failures and site disasters.
Because of its industry leading availability, the Exadata Database Machine has been
deployed by leading companies for their most critical applications including
interbank fund transfers, online securities trading, real-time call tracking, and web-
based retailing. Mission Critical availability is not restricted to OLTP workloads; it
also applies to warehousing and analytics workloads.
Comprehensive System Management
Oracle Enterprise Manager 12c uses a holistic approach to manage the Exadata
Database Machine and provides comprehensive lifecycle management from
monitoring to management and ongoing maintenance for the entire system. It
provides a unified view of all the hardware and software components such as
database servers, Exadata storage, and InfiniBand switches and allows monitoring
the operations running on them and their resource utilization. DBAs can drill down
from database monitoring screens to the storage layer of the Exadata Database
Machine to quickly determine the root cause of application level performance
bottlenecks. Lights-out monitoring within Enterprise Manager is optimized for the
Exadata Database Machine with predefined metrics and thresholds so that
administrators receive timely notifications when issues arise. In addition, hardware
incidents are automatically detected and service requests logged to reduce problem
resolution time. Administrators can use Consolidation Planner in Oracle Enterprise
Manager to determine optimal consolidation strategies for different Exadata
Database Machine configurations and the Cloud Management Pack to manage
Database as a Service deployment.
Ideal Platform for Database as a Service Private or Public Cloud
The Exadata Database Machine can host many databases, enabling Database
Consolidation or a sophisticated Database as a Service (DBaaS) Cloud. Multi-
Database environments inherently have diverse, complex, and unpredictable
workloads mixing OLTP, Analytics, and Batch operations with sequential and
random access patterns. Exadata’s ability to run any type or mix of database

ORACLE DATA SHEET
10
workloads with industry leading scalability and performance makes it an ideal
platform for multi-database workloads.
Multi-database environments create an inherent risk that one database will consume
too many resources and therefore impact the quality of service of other databases.
The Exadata Database Machine provides unique end-to-end prioritization from the
application to database CPUs, network, and storage. Priorities and resource limits
can be specified at the physical database, pluggable database, connection,
application, user, or even job level to ensure that each of the consolidated databases
or SQL operations receives the necessary resources and achieves the target response
times.
Exadata implements unique database and I/O resource management. Fine-
grained priorities specified for operations at the database level are automatically
communicated to Exadata Storage Servers and applied to each I/O operation to
ensure that prioritization of database operations applies to both CPU operations and
I/O operations.
Exadata also implements unique database network resource management to
ensure that network intensive workloads such as reporting, batch, and backups don’t
stall response time sensitive interactive workloads. Latency sensitive network
operations such as RAC Cache Fusion communication and Log File Writes are
automatically moved to the head of the message queue in server and storage network
cards as well as InfiniBand network switches, bypassing any non-latency sensitive
messages. Latency critical messages even jump ahead of non-latency critical
messages that have already been partially sent across the network, ensuring low
response times even in the presence of large network DMA (Direct Memory Access)
operations.
Fast Deployment of Development and Test Databases with Exadata
Snapshots
Space efficient Database Snapshots can be quickly created for test and development
purposes directly on Exadata. Exadata database snapshots are integrated with the
Multitenant Database Option to provide an extremely simple interface for creating
new PDB snapshots.
Snapshots start with a shared read-only copy of the production database (or PDB)
that has been cleansed of any sensitive information. As changes are made, each
Snapshot writes the changed blocks to a sparse disk group. Multiple users can create
independent snapshots from the same base database. Therefore multiple test and
development environments can share space while maintaining independent
databases for each task.
All Exadata specific features such as Smart Scan, resource management and Smart
Flash Cache work seamlessly on database instances created via Exadata snapshots
hence providing an exact test and development environment while using a fraction
of valuable storage resources.
Highest Level of Service
Oracle offers a complete set of support services for the Exadata family of products

ORACLE DATA SHEET
11
including: 24x7 hardware service, system monitoring, software installation and
configuration among other standard and custom offerings.
Of particular value is Oracle Platinum Services which is available exclusively for
Oracle’s Engineered Systems. Platinum Services provides fault monitoring, faster
response times, and expedited escalation to development. With Platinum Services,
fault monitoring, Oracle engineers perform software maintenance, and patching
remotely. Platinum Services provides a higher level of support than has ever been
available before for all software and hardware within an Engineered System
including the Oracle Database. Platinum Services is provided at no extra charge to
Exadata customers.
IT Agility
Exadata is a complete system for running databases including storage, servers, and
internal networks. Management of a traditional database system is typically spread
across the management teams of each of the components such as the database team,
the storage team, and the system administration team. In contrast, an Exadata
system is typically managed by a single Database Machine Administration
team. Database Machine Administrators have full control of all resources in the
Exadata Database Machine including storage resources. New database deployments
and configuration changes can be implemented by the Database Machine
Administrators without coordination across different component management teams
that are often overloaded and have differing priorities. Database Machine
Administrators can focus on application and business specific enhancements rather
than coordinating across component teams, or tuning and triaging of low level
configuration issues.
Dramatically Lower Costs
Because of the extreme performance, high storage capacity, and unique compression
capabilities delivered by the Exadata Database Machine, workloads that would
require very large traditional hardware systems can be run on much smaller Exadata
systems. The hardware needed for an application deployed on an Exadata system is
often reduced 10X compared to a traditional system.
Exadata provides a huge RAM, flash and disk footprint for large data sets. Raw
storage on an Exadata full rack exceeds 670 TB and Hybrid Columnar Compression
often expands storage and memory capacity 10X. By intelligently moving active
data across storage and memory tiers, Exadata simultaneously delivers the highest
performance and the lowest cost.
Exadata has the unique ability to consolidate many databases supporting multiple
workloads in a single cloud platform. High-end OLTP, analytics, batch, reporting,
and backups can all run simultaneously within and across databases with extreme
performance. The extreme performance and capacity of Exadata enables very
large numbers of databases and workloads to be consolidated on Exadata.
Consolidating databases on Exadata reduces system hardware cost, software cost,
and greatly reduces ongoing operations cost.
The uniformity of Exadata Database Machine configurations results in large cost

ORACLE DATA SHEET
12
savings. Exadata standardizes not just technologies, but also integration,
testing, hardening, tuning, and support. Customers deploy Exadata systems much
faster and with a lot less labor than traditional systems. Low level tuning,
integration, and maintenance is reduced or eliminated. Because all Exadata users run
a configuration that is identical to thousands of other users, and is identical to
Oracle’s internal configurations, it is far less likely that issues will be encountered,
and issue resolution is quicker and simpler reducing both operations cost and
downtime cost.
Exadata Business Benefits
Beyond the operational benefits of extreme performance, availability, and security at
low cost, Exadata also directly benefits the business.
Exadata accelerates time to market for new business applications since the time
needed for system configuration, tuning, and testing is largely eliminated.
Deployment times are reduced from months to days, and the risk of unexpected
system level issues after go-live is greatly reduced. When a new application is
deployed, it is common for unanticipated application usage patterns to create
performance issues. Exadata’s huge I/O, network, and compute throughput can
absorb spikes created by unanticipated workloads without slowing response times of
mission critical workloads. Overall Exadata speeds application deployment and
reduces risk allowing businesses to innovate faster.
Exadata’s extreme performance and large memory and flash capacity enhances
employee productivity and customer satisfaction by greatly improving user response
times. Users spend more time doing useful work, and less time waiting for the
system to respond.
Exadata’s extreme performance does not just improve business efficiency, it also
enables business users to make smarter decisions, discover growth
opportunities, and reduce costs. Users can analyze data in real-time, explore
different possibilities, and perform rapid iteration to find better solutions. Exadata
enables:
• Real-time business data analysis
• Faster financial closes
• Better planning and budgeting
• More effective and faster projections
Conclusion
Exadata delivers a fully integrated database platform with the latest hardware
technologies and unique software to deliver extreme performance, availability, and
security. This coupled with cost savings, ease of management, and enhanced
supportability result in greater business agility and efficiency. Given what can be
achieved with Exadata, it is no surprise it is the new global standard for running
Oracle Database.

Actual system performance varies by application.
1
EF = Extreme Flash; HC = High Capacity
2
Bandwidth is peak physical scan bandwidth achieved running SQL, assuming no database compression. Effective user data
bandwidth is higher when database compression is used.
3
Based on 8K IO requests running SQL. Note that the IO size greatly affects Flash IOPS. Others quote IOPS based on smaller
IOs that are not relevant for databases.
4
Based on 8K IO requests running SQL. Flash write I/Os measured at the storage servers after ASM mirroring, which usually
issues multiple storage IOs to maintain redundancy.
5
Raw capacity is measured in standard disk drive terminology with 1 GB = 1 billion bytes. Usable capacity is measured using
normal powers of 2 space terminology with 1 TB = 1024 * 1024 * 1024 * 1024 bytes.
6
Actual space available for a database after mirroring (ASM normal redundancy) while also providing adequate space (one
disk on Quarter and Half Racks and two disks on a Full Rack) to reestablish the mirroring protection after a disk failure in the
normal redundancy case.
7
Effective Flash Capacity is larger than the physical flash capacity and takes into account the high flash hit ratios due to
Exadata’s intelligent flash caching algorithms, and the size of the underlying disk storage. It is the size of the data files that
can often be stored in Exadata and be accessed at the speed of flash memory.
8
Load rates are typically limited by database server CPU, not IO. Rates vary based on load method, indexes, data types,
compression, and partitioning.

Elastic Configuration Performance is computed by taking the minimum of the sum of database server’s performance and sum
of storage server’s performance. For example a configuration consisting of 3 database servers (3x518,000 = 1554K Read
IOPs) and 4 HC storage servers (4 x 400,000 = 1600K Read IOPs) will have a read performance of 1554K IOPs.
Actual system performance varies by application.
