for large-enterprise data center applications and consolidations  
IBM System Storage N7000 Modular  
Disk Storage Systems  
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.  
Highlights  
Scalable—Designed for non-  
disruptive expansion to more  
than 1.1 petabytes (1.1 PB, or  
1100 TB) storage capacity  
Efficient consolidation—  
Intended to provide storage for  
multiple applications in a single  
system with FlexShare™ to  
ensure that critical workloads  
get priority service  
These demands call for enterprise-class  
storage systems with the flexibility to  
support changing IT requirements,  
accommodate continuous data growth,  
satisfy application-level service require-  
ments and unify SAN and NAS infra-  
structures with the expectation of  
reducing overall costs.  
Versatile—Single, integrated  
architecture designed to sup-  
port concurrent block I/O and  
file serving over Ethernet  
and Fibre Channel SAN  
infrastructures  
Application availability—N7000  
systems with Data ONTAP®  
enable application-level recov-  
ery in minutes, not hours, upon  
failure or user error  
Flexible—Fibre Channel and  
SATA disk-drive capabilities  
allow for deployment in multiple  
solution environments, includ-  
ing data retention, near-line  
storage, disk-to-disk backup  
scenarios and high-  
Performance—Delivers high,  
consistent performance for  
mission-critical applications  
performance, mission-critical  
I/O intensive operations  
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  
standard feature of Data ONTAP, makes  
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.  
storage architecture.  
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  
applications.  
It helps prevent the alteration of busi-  
ness records and allows data to be  
rapidly accessible online for long peri-  
ods of time.  
systems. This functionality is designed  
to prevent critical files from being  
altered or deleted until a specified  
retention date.  
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  
address regulatory and best-practices  
records retention requirements by sup-  
porting the creation of non-rewritable,  
non-erasable volumes on IBM N series
