Storage Arrays

Copyright © 2010, Oracle and/or its affiliates. All rights reserved.

Traditional Enterprise Database Storage Deployment
The graphic in the slide illustrates the traditional deployment approach for multiple databases.
Each database has an isolated allocation of storage resources and its bandwidth is limited by
the hardware allocated to it. The isolation and dedication of hardware resources to individual
databases can simultaneously lead to unused space and unused input/output (I/O) bandwidth
for some databases, and overcommitted bandwidth with insufficient free space in others. The
right balance is almost never achieved because real-world workloads are very dynamic.
Large storage arrays are used today for many enterprise database deployments. These large
storage arrays must be partitioned and have their bandwidth and space allocated across the
d t b
databases
and
d applications
li ti
sharing
h i th
the storage
t
array. B
Because th
these storage
t

arrays h
house
vast quantities of mission-critical data, they must be highly engineered, and consequentially
very expensive, to deliver high levels of reliability and availability. Enterprise-class storage
arrays are not only costly to procure, they also require highly specialized skills to manage and
maintain. The result is a very high total cost of ownership when traditional large storage
arrays are used in real-world enterprise database deployments.

Exadata Storage Deployment
The graphic in the slide illustrates the general deployment approach with Exadata.
• You can use Exadata to consolidate your storage environment
environment. Using Exadata
Exadata, multiple
databases can use storage from a single pool. Exadata uses Oracle Automatic Storage
Management (ASM) to evenly distribute the storage load for every database across
every available disk in the storage pool. Every database can use all the available disks
to maximize performance. Exadata requires the use of Oracle Database 11g Release 2.
Exadata works equally well with single-instance or Oracle Real Application Clusters
(RAC) databases. Users and database administrators use the same tools and
k
knowledge
l d they
th are already
l d familiar
f ili with.
ith B
Being
i b
based
d on iindustry-standard
d t
t d d components
t
and technologies, Exadata is inexpensive to deploy. In addition, tight integration with the
full suite of Oracle Database high-availability features, ensures that the reliability and

integrity needs of mission-critical environments are met.
• A key advantage of Exadata is the ability to offload some database processing to
Exadata servers. With Exadata, the database can offload single table scan predicate
filters and projections, join processing based on bloom filters, along with CPU-intensive
decompression and decryption operations. This ability is known as SQL processing
offload or Smart Scan.

•

In addition to Smart Scan, Exadata has other smart storage capabilities including the
ability to offload incremental backup optimizations, file creation operations, and more. This
approach yields substantial CPU
CPU, memory
memory, and I/O bandwidth savings in the database
server resulting in potentially massive performance improvements.
Exadata includes Exadata Hybrid Columnar Compression. This feature provides very high
levels of data compression implemented inside Exadata. Exadata Hybrid Columnar
Compression allows the database to reduce the number of I/Os required to scan a table.
For example, for data with a compression ratio of 10 to 1, the I/Os required to scan the

data are reduced from 10 to 1 as well.
Exadata ensures that I/O resources are made available whenever, and to whichever,
database needs them based on priorities and policies that you can define. The Database
Resource Manager (DBRM) and Exadata I/O Resource Management (IORM) work
together to manage intradatabase and interdatabase I/O resource usage to ensure that
your defined service-level agreements (SLAs) are met when multiple applications and
databases share Exadata storage.
Finally, even for queries that do not use Smart Scan, Exadata has many advantages over
conventional storage. Exadata is highly optimized for fast processing of large queries. It
has been carefully architected to ensure no bottlenecks in the controller or in other
components inside the storage server. It makes intelligent use of high-performance flash
memory to boost performance and also uses a state-of-the-art InfiniBand network that has
much higher throughput than conventional storage networks.

Exadata Implementation Architecture Overview
Exadata is a self-contained storage platform that houses disk storage and runs the Exadata
Storage Server Software provided by Oracle
Oracle. A single Exadata server is also called a cell
cell. A
cell is the building block for a storage grid. More cells provide greater capacity and I/O
bandwidth. Databases are typically deployed across multiple cells, and multiple databases
can share a single cell. The databases and cells communicate with each other via a highperformance InfiniBand network.
Each cell is a purely dedicated storage platform for Oracle Database files although you can
use Database File System (DBFS), a feature of Oracle Database, to store your business files
i id the
inside
th d
database.
t b

Like other storage arrays, each cell is a computer with CPUs, memory, a bus, disks, network
adapters, and the other components normally found in a server. It also runs an operating
system (OS), which in the case of Exadata is Linux. The Oracle-provided software resident in
the Exadata cell runs under this operating system. The OS is accessible in a restricted mode
to administer and manage Exadata.

Introducing Exadata
Exadata is highly optimized for use with Oracle Database. Exadata delivers outstanding I/O
and SQL processing performance for data warehousing and online transaction processing
(OLTP) applications.
Exadata is based on a 64 bit Intel-based Sun Fire server. Oracle provides the storage server
software to impart database intelligence to the storage, and tight integration with Oracle
Database and its features. Each cell is shipped with all the hardware and software
components preinstalled including the Exadata Storage Server Software, Oracle Linux
x86_64 operating system and InfiniBand protocol drivers.
Since March 2010, Exadata is no longer offered as a standalone storage product. Now
Exadata is only available for use in conjunction with Database Machine. Individual Exadata
servers can still be purchased, however they must be connected to Database Machine.
Custom configurations using Exadata are no longer supported for new installations.
