IBM LTO products: a guide for the midmarket


Introduction

While disk storage has evolved greatly over the years, tape continues to be an

integral part of the storage hierarchy. For example, IBM studies show that our

clients store from four to 15 times more data on tape than disk. The reasons

provide substantiation for why tape storage is so popular. Compared to disk

storage, tape is:

• Cost-effective

• Uses less energy

• Is removable and portable

• Can hold high volumes of data

• Has a long life, and

• Is ideally suited for information availability, retention, security and compliance

Faced with an information explosion that means the need for more and affordable

storage, IT managers, trying to optimize space, storage and people can find IBM

tape storage the solution to many of your problems. The following information

will help you understand the advantages of choosing IBM as your vendor for

Linear Tape-Open (LTO) storage products.

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


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:

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.

• Asanexample,IBMMediaundergoesEnvironmentalDurabilityTestsatall

“ five corners” of the temperature and humidity extremes. It is our belief that only

IBMputsmediathroughitsentirelifecycle(300completefullfilepasses*)at

eachpoint(Warm/Wet,Hot/Wet,Hot/Dry,Cold/DryandCold/Wet).Manyother

vendorsmaytakecartridgesamplesthrougheachextremepoint,butmaynotput

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:

– 300fullfilepasses

– 1 million head passes

– 20,000 short section durability passes at all environments

– 20,000 load/unload cycles


(Note:FullFilePassisaprocessthatfillsanentiretape.Afullfilepassofan

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.


IBM Media is designed for increased reliability, performance, stability

and durability

• TheIBMLTOcartridgeusesanultra-thin dual coating system which provides

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.

• IBMLTOTapedrivesemployspecificpatentedtechnologies,whichfurther

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.


IBM has renewed its commitment to addressing the needs of midsize businesses

(those with 100 to 1000 employees). We know that factors such as simplicity,

scalability and cost are critical considerations for smaller enterprises. That’s why

IBM offerings for midsize business conform to a set of strict requirements that

helps ensure usability, easy acquisition and implementation, flexibility and faster

return on investment.

For the majority of midsize businesses, the term “enterprise IT” brings to mind

two words: expensive and complex. But IBM LTO solutions for midsize businesses

are geared to ensuring that companies like yours can have all the power,

performance, security and reliability they need with a variety of products that

help meet data back up and restore needs — at an affordable cost, and with plenty

of room to grow.

IBM has a complete portfolio of solutions for midsize businesses that include

hardware, software, middleware, services and financing options.

Highlights

Did you know? The tale of the tape

IBM tape storage has many reasons for

usage, whether in general or specific

to LTO. What makes LTO the right fit

and the ideal fit is listed here:

Energy consumption

A study of a midsize business storage

scenario found that a disk system can

cost 290 times more in power and

cooling than a tape system.1 As a rule,

tape drives and libraries consume far

less energy than disk drives and bays,

and tape cartridges require no energy

at all when stored.

Overview of IBM LTO tape storage products

The following are descriptions of LTO Ultrium tape drives, libraries and

autoloaders in our LTO portfolio.

IBM System Storage TS2240 Tape Drive Express Model

The IBM System Storage TS2240 Tape Drive Express Model is an external

drive incorporating the fourth generation of IBM LTO technology in a half-high

form factor. This is an external stand-alone or rack-mountable unit, similar to

previous models of the TS2230 and is the entry point for the IBM Ultrium tape

product family. The TS2240 supports encryption of data with a 3 Gbps SAS

connection. In addition, the TS2240 can read and write LTO Ultrium 3 Data

Cartridges and read LTO Ultrium 2 Data Cartridges. The TS2240 Tape Drive

provides an excellent migration path from digital linear tape (DLT or SDLT),

1/4-in., 4 mm, or 8 mm tape drives.

Max. drive data rate Up to 120 MB/sec native

IBM System Storage TS2340 Tape Drive Express Model

The IBM System Storage TS2340 Tape Drive Express Model is an external

drive incorporating the fourth generation of IBM LTO™ technology in a full high

form factor. This is an external stand-alone or rack-mountable unit, similar to

previous models of the IBM 3580 and is the entry point for the IBM Ultrium

tape product family. The TS2340 supports encryption of data and offers a 3 Gbps

SAS connection. In addition, the TS2340 can read and write LTO Ultrium 3

Data Cartridges and read LTO Ultrium 2 Data Cartridges.

Cartridge capacity 800 GB native physical capacity

Interface LVD SCSI, 3 Gbps SAS

Max. drive data rate Up to 120 MB/sec native

Price

A study of a midsize business storage

scenario found that a disk system

could cost 23 times more in total cost

than a tape system.2 Hardware, energy

consumption and floor space are

typically lower with tape.

The low cost per GB of tape storage is

approximately four cents per GB for an

LTO-4 cartridge,3 and that facilitates

keeping multiple copies of the data for

backup, recovery and archiving

purposes.

Removable disk cartridges cost

approximately $1.45 per GB 4

Automated tape and virtual tape

libraries with advanced backup and

archive management software reduce

or eliminate the need for IT staff,

allowing “people costs” required for

managing and maintaining disk- or

tape-based data protection solutions

to be roughly the same.5

generation 4 at no additional cost.

IBM tape drive encryption was first to

market and it has been securing

customer’s information on tape

since 2007.

The impact of hardware encryption on

tape LTO drive performance is

expected to be typically less than one

percent.6

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,IBMwasnamedthetopcompanyforclimatechangestrategyand

practices in a report released by the Ceres investor coalition. The report

analyzedclimatechangegovernancepracticesat63oftheworld’slargestretail,

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.
