The challenge: Managing data for business
advantage
In an increasingly demanding and com-
petitive business landscape, effective
data management is essential to the
success of the enterprise. Data avail-
ability from any location gives employ-
ees, partners and customers the
up-to-the-minute information they need
to work productively, make timely deci-
sions and meet business goals.
Information technology professionals
facing these challenges are under pres-
sure to deliver more capacity and at
higher levels of service. Yet critical
resources—staffing, budget, power,
cooling and floor space—are often
constrained.

Another feature of the N series Data
ONTAP operating system, FlexClone®,
enables the nearly instant creation of
clones without requiring incremental
storage. FlexClone can dramatically
accelerate test and development cycles
for IT projects.
Application availability. N7000 sys-
tems combine a variety of features to
meet the need for continuous availabil-
ity. Complementing the high-availability
hardware design is the proven reliability
of the Data ONTAP operating system
and RAID-DP™ (N series implementa-
tion of RAID-6), which uniquely provides
double-level RAID data protection to
help ensure that data is not lost in the
event of multiple disk drive failures. In
addition, RAID-DP has negligible per-
formance impact. The N7000 also sup-
ports simple yet powerful synchronous,
semi-synchronous and asynchronous
mirroring that can be deployed
it possible to instantly revert to a
previous version of data upon failure or
user error. N series Snapshot copies
are unique in that they can be created
frequently during production, because
they use only a small amount of incre-
mental storage and have virtually no
impact on performance. Host-based
SnapManager® software integrates
Snapshot management with applica-
tions, designed to ensure consistent
backup images and application-level
recovery in minutes.
Efficient consolidation. The N7000
series is designed to consolidate
and serve data for a wide variety of
workloads, including mission-critical
business applications, technical appli-
cations, databases, e-mail, home direc-
tories, digital media, backup and
Performance. High performance and
massive storage capacity are character-
istics that make the N7000 systems
ideal for large-scale applications and
storage consolidation. An N7000 sys-
tem is designed to complete jobs
quickly and handle a large number of
users via a powerful, high-bandwidth
architecture with scalability to
recovery, regulatory compliant data
retention and archival. IBM N series
systems support Windows®, UNIX®,
including AIX®, Solaris™ and HP-UX,
and Linux® host operating systems as
well as VMware for server virtualization.
in one-to-one, one-to-many and many-
to-one mirroring configurations.
The N7000 can serve as the foundation
for a comprehensive data management
solution consisting of hardware, soft-
ware and services. With an appliance
architecture and built-in backup and
recovery software, an N7000 solution is
designed to address the entire spec-
trum of data availability challenges while
offering value in price/performance and
scalability.
IT organizations can be challenged with
poor response times during peak hours
of operations after consolidating stor-
age systems with dissimilar data work-
loads on to a single platform. To help
address this challenge, N series offers
FlexShare quality-of-service software,
which is intended to enable storage
administrators to set and dynamically
adjust workload priorities. FlexShare
can help ensure that important applica-
tions get fast response times.
1,176 disk drives capable of delivering
up to 1.176 PB of raw storage capacity.
With large cache memory configura-
tions, expandable high-performance
I/O, 4 Gbps FC SAN support, 4 Gbps
disk drive support and support for
10 Gbps Ethernet, the N7000 delivers
exceptional enterprise-class system
performance.
Ultimately what matters is application-
level availability, and this is where
N series systems excel. Snapshot™, a

N7000 near-line storage capabilities
The N7000 is well suited for near-line
storage configurations. An N7000 sys-
tem populated with Fibre Channel disk
drives that backs up to another
component in an information lifecycle
management process by storing less-
critical data on a device whose cost
and performance stand between pri-
mary and tape storage.
IBM N series systems using
NearStore® software can use the
Advanced Single Instance Storage
(A-SIS) software feature for better stor-
age utilization. A-SIS software enables
N series systems to deduplicate stored
data at the block level in order to con-
serve physical disk space when making
disk-to-disk copies of primary data.
Traditionally when copies of volumes
are created, every duplicate data string
is also copied, resulting in an inefficient
use for secondary storage. A-SIS dedu-
plication helps eliminate this inefficiency.
N series system populated with SATA
disk drives offers disk-to-disk backup
capabilities that are designed to help
you fill the price/performance gap
between fast but costly primary storage
and less-costly but slow archival (tape
and optical) storage. Utilizing SATA disk
drive technology, you could achieve
near-primary storage performance at
near-tape storage costs. A disk-based,
secondary storage device for enterprise
applications, N7000 disk-to-disk envi-
ronments are designed to complement
and dramatically improve existing tape
backup, archiving and data protection
schemes. They do so by inserting eco-
nomical and simple-to-use disk-based
storage between application storage
and tape libraries in a three-tier
Combined with SnapVault®, the N7000
disk-to-disk backup environments are
designed to serve as a robust and fully
integrated appliance that makes back-
ing up and restoring data rapid and reli-
able. Backing up directly to an N7000
system in a near-line storage configura-
tion and then to tape can help your
organization enhance data protection
management, improve primary storage
and tape library performance, and
reduce backup resource requirements
and costs. Two N series systems oper-
ating in a disk-to-disk backup scenario
are designed to be faster and to con-
sume less application-server CPU pro-
cessing power than direct backup to
tape. SnapVault software can be used
to help reduce network bandwidth con-
sumption by supporting incremental
block transfers to backup data across a
LAN or WAN. SnapMirror® software,
which replicates data at high speeds
over a LAN or a WAN, is designed to
provide high data availability and
Support for data retention through non-
erasable, non-rewriteable security
capabilities
The N7000 offers multiple capabilities in
the area of data retention. It can serve
as a high-performance device for stor-
ing mission-critical production data and
as a data-retention system by running
SnapLock® software. The N7000 with
SnapLock software is designed to
deliver high-performance and high-
security data permanence to disk-
based nearline and primary N series
storage. An optional feature of the
proven Data ONTAP operating system,
SnapLock software supports the accu-
racy, integrity and security of data.

This arrangement is designed to pro-
vide economical storage and rapid
disk-based access to reference data to
help address business and regulatory
requirements. It can serve as a key
fast recovery for mission-critical

systems. This functionality is designed
to prevent critical files from being
altered or deleted until a specified

non-rewriteable replication of data at
remote sites can help your organization
address regulatory concerns or best
practices, resulting in a highly robust
compliant data protection solution.
Non-erasable, non-rewriteable data
can also be backed up to tape for an
additional level of data protection.
SnapLock offers capabilities to help you
