What are the benefits of LTO in general and IBM LTO in particular?
IBM LTO technology has evolved through four generations, with two more
planned. LTO is an open tape architecture developed by a consortium of three
world-class storage producers, including IBM..
LTO solutions have many advantages over other types of storage. For example,
LTO provides highly scalable tape backup that accommodates a wide range of
system formats. It easily integrates into current operating environments, and our
roadmap protects your investment today and in the future. The LTO Ultrium
format offers exceptional investment protection. As a truly open tape solution,
the Ultrium format has gained widespread industry acceptance from leading tape
drive, media, and automation companies. Simplified product planning means
faster cycle time for new features
IBM offers a complete family of solutions comprising tape drives and small-
medium- and large tape automation solutions that use the Ultrium ultra-
high-capacity recording format. This family delivers exceptional performance,
widespread availability, and a lower-price data storage solution:
• High reliability levels. When you entrust your data to a storage medium, you
want the very highest levels of reliability. For more than 55 years — longer than
any other major storage vendor — IBM has been leading the way in tape storage
technology
• High capacity. Up to 1.6 TB compressed or 800 GB of native capacity data can fit
on a single compact cartridge
• High data transfer rate. Sustained data transfer rates of up to 120 MB/second are
supported in the IBM LTO 4 generation
4. IBM LTO products: a guide for the midmarket
Page 4
Our LTO Ultrium solutions are designed to grow with your needs, across
platforms and operating systems, and in fact, IBM has invented much of today’s
most advanced storage technology Did you know that:
• IBM introduced the first tape drive in 1952 and the first disk drive in 1956. The
IBM LTO-based Ultrium format tape drives are simply the latest IBM storage
developments to leverage this unparalleled track record of innovation and
expertise.
• The IBM Ultrium format technology leverages earlier IBM innovations as
building blocks for enhancement.
• The dramatic increases in linear and track density, and the use of multi-
track, linear-serpentine recording are natural extensions of existing IBM tape
technologies.
• The enhancements in tape track and magneto-resistive (MR) head technology
leverage the high number of concurrent channels and track density characteristics
of the LTO specifications.
• The error correction code (ECC) used in the IBM Ultrium tape products is
powerful enough to ensure reliable recovery of data even with the loss of a track
or head. The high efficiency ECC is based on the same architecture as existing
IBM tape technologies
• When you choose IBM, you have immediate access to an end-to-end solution
whatever the requirement. From individual tape drives to ultra-scalable libraries
to disk, IBM has a solution for your needs.

The IBM difference
IBM has superior quality and reliability specifications for its media, drives and
automation. For example, “IBM LTO-4 media specifications go well beyond
standard LTO specifications. Here are some examples of the quality and
reliability that we build into our products.
IBM media is built to rigorous IBM specifications
IBM media undergoes far more testing than any other tape media, even non-IBM
branded media manufactured in the same plant.
• As an example, IBM Media undergoes Environmental Durability Tests at all
“ five corners” of the temperature and humidity extremes. It is our belief that only
IBM puts media through its entire life cycle (300 complete full file passes*) at
each point (Warm/Wet, Hot/Wet, Hot/Dry, Cold/Dry and Cold/Wet). Many other
vendors may take cartridge samples through each extreme point, but may not put
the cartridge through its entire life cycle at each data point.
• Commonality of Format does not imply commoditization. LTO Consortium
Certification is not a statement of quality. Certification only promises
interchangeability and capacity specification at a minimum quality. IBM
has superior quality and reliability specifications for its media, drives and
automation. For example, IBM LTO4 media specifications go well beyond
standard LTO specifications by ensuring that the media will be capable of
adhering to and be covered by warranty to the following specifications:
– 300 full file passes
– 1 million head passes
– 20,000 short section durability passes at all environments
– 20,000 load/unload cycles
6. IBM LTO products: a guide for the midmarket
Page 6
(Note: Full File Pass is a process that fills an entire tape. A full file pass of an
IBM LTO4 cartridge requires sixteen tracks to be written from one end of tape
to the other and repeating this process 56 times to completely fill the 800 GB
cartridge. Other vendors may consider a full file pass to be simply one “round
trip” from beginning of tape to end of tape and back. There are 28 “round trips”
in a full file pass.
• IBM Media is used as the Master Standard Reference Tape at the Measurement
Assurance Corporation, the third party that performs compliance testing for the
LTO consortium. The Master Standard Reference Tape is the tape media that all
other vendors are compared against. Being chosen as the MSRT is an indication
of predictability and consistency from cartridge to cartridge so that the standard
does not change. IBM has been the MSRT supplier for all four LTO generations.
• IBM has the most extensive suite of stress tests built over years of tape media
development for stress testing media in real and extreme customer environments.
While the content of this test suite is proprietary, the history and experience we
have in continuing to develop our testing methods means we have discovered how
to solve problems that other vendors haven’t even discovered are problems.
7. IBM LTO products: a guide for the midmarket
Page 7
IBM Media is designed for increased reliability, performance, stability
and durability
• The IBM LTO cartridge uses an ultra-thin dual coating system which provides
increased durability and stability. Ensuring an ultra-thin magnetic layer is
critical to the life of a cartridge, as the higher areal density media requires a very
low background signal noise to ensure that data, once written, will not become
altered due to signal-to-noise loss. This Dual Coat Process was developed by our
media manufacturing partner Fujifilm, and this thin magnetic coat, as a result,
delivers long shelf life and durability.
• The IBM LTO cartridge has LTO CM (cartridge memory) chip. During the media
(unload/load) cycles, the CM 8KB memory chip uses a radio frequency interface
that eliminates any need for a physical power or signal connection between the
cartridge and the drive. It holds information about data location, usage/error
logs, and user areas. It provides a quick reference to the cartridge’s index and
usage information, facilitates problem diagnosis and helps with failure prediction,
minimizes load time, and provides fast access to and high-speed restoration from
files and data sets regardless of their location on the tape cartridge.
• Includes improved PEN substrate which is very stable under changing
environmental conditions
• Uses dual servo tracks for extremely fine placement control and redundancy in
the event of tape damage
• Uses advanced slitting technology
• Results in maximum edge quality, ensuring superior reliability, enhanced
performance and reduced debris
8. IBM LTO products: a guide for the midmarket
Page 8
IBM Drives and IBM Media are designed and developed together
One cannot overstate the significance in building a cartridge to work with a
particular drive, or a drive with a particular cartridge. And, IBM drives are found
in tape libraries from SUN (STK), Dell, ADIC and many others.
• IBM LTO Tape drives employ specific patented technologies, which further
enhance the capabilities of IBM’s LTO media when used together:
– Patented Magneto Resistive flat lapped head design – Helps reduce tape wear
by decreasing the tape to head contact found in typical tape drives. IBM
LTO tape is kept in place with minimal friction using normal air pressure to
keep the tape in proper contact with the head read and writes elements. This
head design helps improve performance, accuracy and reliability of reads and
writes and helps to reduce tape media and drive head wear.
– Patented surface control guiding system – Allows for less debris generation
and increased performance. The flat lapped heads and surface control
guidance system help contribute to overall high data integrity in the IBM LTO
tape drives.
– Grooved Roller Surface Control Guiding – Helps to stabilize the lateral
movement of tape across the head, reducing the amount of re-reads or writes
that might occur if the tape path weren’t so stable. The two inner most rollers
are actually grooved, which causes air to “bleed-out” from underneath the
surface of the tape, allowing more precise guiding of the tape without having
to rely upon edge guiding like done on many other systems.

IBM, LTO and the midmarket
With smaller, more agile rivals on one side and larger, more powerful ones on
the other, medium companies such as yours must respond rapidly in a changing,
competitive environment. Current market data shows that medium businesses
face an array of challenges specific to their unique position in the marketplace.
Security issues, for example, remain a top priority, while the need for real-world
business intelligence has become a top driver of new technology implementation.
Companies must ensure product and services differentiation to compete in an
ever-changing marketplace and be nimble enough to adapt to those changes.
Other market trends shaping the business landscape, such as information
on demand or virtualization solutions, are also on the medium company’s
radar — although many businesses lack the resources to move in those directions
on their own.
Medium-sized companies need to compete at the highest level, maintain
business models and support systems flexible enough to prioritize and capture
the most valuable opportunities — and do all this with fewer resources than larger
enterprises. Also, organizations worldwide are required by law to store, manage
and safeguard more of their data than even before. Meeting these goals requires
some creativity and the right technology partner. More than ever, medium
companies are recognizing the advantage of technology solutions to help them
win in the marketplace.

Environmental considerations
IBM is committed to environmental leadership in all of its business activities,
from its operations to the design of its products and use of its technology. IBM’s
corporate policy on environmental affairs, first issued in 1971, is supported by
the company’s global environmental management system. This is a key element
of IBM efforts to achieve results consistent with environmental leadership and
ensures that the company is vigilant in protecting the environment across all
of its operations worldwide. Here are some examples of IBM “green” efforts and
recognition for them:
• Recently, IBM was named the top company for climate change strategy and
practices in a report released by the Ceres investor coalition. The report
analyzed climate change governance practices at 63 of the world’s largest retail,
pharmaceutical, technology, apparel and other consumer-facing companies.
• Between 1990 and 2007, IBM saved 4.6 billion kWh of electricity consumption,
avoided nearly 3.1 million metric tons of CO2 emissions (equal to 45 percent of
the company’s 1990 global CO2 emissions) and saved over $310 million through
its annual energy conservation actions alone.
• IBM’s procurement of renewable energy and RECs increased from 11 million kWh
in 2001 to 455 million kWh in 2007, which accounted for 8.5% of IBM’s total
2007 global electricity purchases.
• To further extend these achievements IBM set a “second generation” goal to
reduce CO2 emissions associated with IBM’s energy use by 12 percent between
2005 and 2012 through energy conservation, use of renewable energy and
funding RECs.

Why IBM storage solutions?
IBM Storage solutions provide the capabilities needed to help organizations
reduce cost and mitigate risks while managing continued information growth and
service level demands. Dynamic environments, such as Cloud Computing and
Service Oriented Architecture, require scalable, always on information services
delivered by a robust information infrastructure foundation.
Storage is as important to a dynamic infrastructure as servers and networks.
Because of the explosion of information in most data centers, storage can be
more challenging to tame than server resources, but the payoff can be worth the
effort. IBM Information Infrastructure solutions can play a critical role in projects
impacting resiliency, security, energy efficiency, virtualization, asset management,
and service management. IBM Information Infrastructure is an initiative that
helps clients meet the challenges of today’s information explosion by helping to
improve competencies in four critical areas:
• Information availability
• Information security
• Information retention
• Information compliance
IBM Information Infrastructure and System Storage solutions can help you
manage information growth more effectively, dramatically improve service levels,
lower costs, mitigate risks, and extract new intelligence for business insight.
