Hot Swap, redundant components; power supplies, fans, disk drives and
storage controller clustering
Connects to NAS, IP SAN and FC SAN environments
Concurrently
40+ Advanced Software Features
Copy Services, multiple protocols, virtualization, WORM data protection,
database usability
FC or SATA or Mixed Disk Drive options
FC drive options
Used for high performance, mission critical production data
SATA options can be used for
Disk backup options (Nearline storage)

Why Gateway vs. General Purpose Filer Server
Storage
Subsystems
Unix Windows Linux
Clients & Servers
.
A single Gateway supports Unix, Linux and
Windows file protocols Potentially reducing the number of servers
required for accessing SAN storage in mixed
protocol environments
Connecting small inexpensive servers to
premium priced SAN storage is very costly.
FC HBAs, FC switch ports costs could exceed
the actual cost of server
A single Gateway extends the reach of SAN
storage to many servers attached to an IP
network
Potentially reducing overall connection costs
Allowing access to SAN storage at extended
distances A Gateway provides functionality of N
series technology to other vendor storage
subsystems
A Gateway provides increased protection
investment in SAN storage by increasing
SAN utilization & accessibility

Danger Zone
Assumes 8-drive (7+1) RAID group
ErrorRates
Industry-wide trend
As disk drive sizes get
larger, the bit error rates
increase (per drive)
Non-correctable errorrate is uncomfortably
close to bits read during
reconstruction

Patented Double Parity RAID: RAID-DP
Designed especially for SATA drive
technology Designed to survive any2-disk-failure
scenario
Breakthrough innovation:
USENIX Best Paper in 2004
Compared to single-parity RAID, RAID-
DP has: Better protection (>4,000 MTTDL)
High performance
Same capacity overhead (typically 1
parity per 6 data drives
Designed to outperform other double-
parity offerings Routinely on during benchmarks
Combined with SyncMirror (RAID1), the
N series products are designed to
survive failure of any five disks in one
disk protection group

Designed to allow the IT administrator
to make a backup copy of a database
and then modify and run testing
against test (backup) database without
affecting or taking the on-line database
off-line.
Designed to allow administrators to create multiple flexible volumes across a large pool of disks. Dynamic, non-
disruptive storage (thin) provisioning; space- and time-efficiency. Allows users to get more space dynamically
and non-disruptively. Can enable more productive use of available storage and helps improve performance.

Disk sanitization is the process of physically obliterating data
by overwriting disks with specified byte patterns or random
data in a manner that helps prevents recovery of current data
by any known recovery methods.
This feature is designed to enable you to carry out disk
sanitization by using three successive byte overwrite patterns
per cycle and a default six cycles per operation

MultiStore is designed to let you quickly and easily
create separate, private logical partitions in filer
network and storage resources.
SnapMover
Local data migration solution for optimizing workloadsacross N series sharing a common disk array.
Designed to allow you to migrate ownership of a volume
from one filer to another filer with a single command.
Designed to allow better resource utilization and
performance amongst multiple N series devices
MultiStore and Clustering are prerequisites
Each virtual storage partition is designed to maintain
separation from every other storage partition to
prevent different enterprise departments that share
the same storage resources from accessing orfinding other partitions.
MultiStore helps prevent information on any virtual
partition from being viewed, used or downloaded by
an unauthorized users.
Similar to LUN masking on a Block Storage System

SnapManager
Host software for managing Exchange and SQL Server backup and
restore. SnapManager software simplifies Exchange data protection
by automating processes to provide hands-off, worry-free data
management.
Designed to enable you to schedule and automate Exchange
database backups, use policy-based backup retention
management, and simplify the migration of existing databases to
IBM N series systems.
SnapManager also delivers built-in high availability, with featuresthat allow you to expand Exchange databases online.
It also offers tight integration with Microsoft Cluster Server (MSCS)
and Multi Path I/O (MPIO) and with the N series Clustered Failover
option and SnapMirror for simplified disaster recovery
implementation.
SnapDrive SnapDrive is designed to allow administrators to easily create virtualdisks from pools of storage that an be distributed among several
storage appliances.
With SnapDrive you add, delete, map, unmap, and mirror virtual disks
online. You can expand capacity on-the-fly with no impact to
application or system performance.
Designed to allow optimized usage in database environments
Virtualized local disk to Windows
servers (FCP or iSCSI). Storage
managed by SnapDrive logically appears to come from a locally
attached storage subsystem.

Oracle Database Server
SnapValidator detects and prevents potentialcorruptions of Oracle data before they happen.
Oracle system assigns a unique value to each write
request based on the sum of the data and sends the
data set down the I/O path to the N series system.
Upon receipt, SnapValidator calculates the sum of the
data and compares it to the Oracle value.
SnapValidator meets Oracle
HARD initiative and provides the
highest possible level ofprotection for Oracle data.
If the identifiers do not match,
the system prevents the data
corruption and produces an alert.
