2. 2 Reliable and efficient backup and recovery for IBM i on IBM Power Systems servers
Tackle tough backup and recovery
requirements in IBM i environments
Many businesses today rely on IBM® Power Systems™ servers
running IBM i to help them meet the challenges of managing
rapid change, reducing business risk and achieving higher service
levels in a more cost-effective manner. IBM i can support the
data protection needs that small, midsized and large organiza-
tions face as they deal with backup for today’s explosive growth
in data and information.
In this scenario, IBM System Storage® ProtecTIER® solutions
can deliver inline deduplication and can protect and retain data
longer and save money by helping to reduce energy, floor space
and maintenance requirements. Fully qualified and certified for
IBM i environments, ProtecTIER solutions can support busi-
nesses of different sizes to harness the power of deduplication to
manage increasingly complex backup demands.
Help accelerate both data backup
and recovery
With data growing at an exponential rate and backup windows
shrinking, businesses need deduplication solutions that can
support both high-performance data backup and rapid data
recovery. Solutions from other vendors may deliver impressive
backup performance, but they are known to be slow in restoring
data. With its revolutionary and patented inline deduplication
algorithm, ProtecTIER helps eliminate redundant data in
near-real-time that is at the same time as data is being received
from the IBM i server. As a result, a single ProtecTIER solution
can provide up to 2500 MB/sec sustained backup throughput
and faster restores at up to 3200 MB/sec sustained recovery
performance.
Capacity to more efficiently respond to
growing data demands
ProtecTIER has a unique deduplication technology that helps
the disk repository of a single ProtecTIER server to scale up to
1 PB without affecting performance. With a deduplication ratio
of 25:1, as much as 25 PB of backup data can be stored on a sin-
gle ProtecTIER server. Unlike hash-based deduplication prod-
ucts whose hash table grows linearly with the amount of data
stored, ProtecTIER can manage a petabyte repository with only
a 4 GB index file. The ProtecTIER non-hash-based approach
also helps reduce the risk of data corruption resulting from
unique data being discarded due to a potential hash collision.

IBM Systems and Technology
Tested in production environments and
certified for IBM i
Since the introduction of ProtecTIER in 2005, IBM has
deployed more than 182 PB of physical capacity behind
ProtecTIER servers around the world, in various production
environments representing a broad range of performance and
capacity requirements that signify more deployed physical
capacity than any other vendor in the market today. ProtecTIER
has also been specifically qualified and certified for IBM i envi-
ronments in testing conducted by the IBM i development team
in Rochester, Minnesota. IBM i testing has shown deduplication
ratios to be comparable to or better than open systems.
ProtecTIER presents a TS3500 virtual library to IBM i hosts
using the same fibre channel connectivity available for physical
tape. A single ProtecTIER server can be shared between open
systems hosts and IBM i hosts. ProtecTIER can integrate more
smoothly into each Backup Recovery and Media Services
(BRMS) environment and helps provide complete support for
BRMS and native IBM i save commands, although BRMS is
strongly recommended.
Making ProtecTIER more effective in an
IBM i environment
The ProtecTIER native replication technology helps enable the
automated electronic replication of backup data between a
primary location and off-site storage locations for more
enhanced disaster recovery (DR) and business continuity. By
eliminating the need to transport physical tape cartridges,
ProtecTIER solutions can support faster and more reliable data
recovery, allowing systems to get back online more quickly in
the event of a disaster or major system outage.
This type of a DR solution is especially effective in large envi-
ronments with many small systems or logical partitions (LPARs)
where a physical tape would be inappropriate as a backup device
due to the labor requirements for handling tape. Instead, the
primary ProtecTIER can be set up with smaller virtual tapes.
Using native IP replication, each of these tapes is designed to
replicate to a remote site forming an effective DR solution.
ProtecTIER can significantly lower the total cost of ownership
for the complete backup and recovery solution by up to
96 percent by helping to reduce the costs associated with moving
and storing physical tape cartridges. Furthermore, the combina-
tion of IP replication and deduplication can significantly reduce
the bandwidth requirements between the primary and DR sites,
which represent significantly lower cost compared to a tradi-
tional replication operation.
Extending the benefits of ProtecTIER
IBM i support extends the benefits of deduplication to a broader
set of users and environments. From its June 2009 introduction,
the ProtecTIER IBM i support has included native replication,
and it can offer key advantages such as support for IBM i 7.1 and
VIOS with NPIV. With our global network of employees and
IBM Business Partner, we can deliver the expertise and resources
needed to design, integrate and support this technology for
organizations of various sizes around the globe.
