Tape Library News

inaccessibility of LTO-8 tape may be a good thing

Editor:- July 16, 2018 - I haven't written much about tape drives and tape libraries in recent years (less than 8 news stories in 8 years as you can see by scrolling below) because the writing which had already been appearing on the wall for a long time - about the mainstream migration away from tape - was still clearly legible despite having been written long ago and crumbling in the dusty vaults of web pages deep down in the logfile statistics.

But a recent blog - Top 8 Reasons To Purchase LTO 8 Tapes - by UK tape reseller ODSI - prompted me to respond on linkedin with this.

"Reason #4 for liking this tape / LTO-8 (resistant to instant malware attacks because data on tape is effectively offline) is a clever way to argue that a negative feature can have positive aspects when viewed in a particular context. Shows that the art of tape marketing sophistry hasn’t been lost despite the demise in significance of the tape market itself."

As flash puts the squeaze on D2d will tape benefit as a zero energy archive?

Editor:- October 20, 2016 - Have you wondered what has been happening in the tape storage industry, if anything? - said Fred Moore, President - Horison Information Strategies - in the enticing preamble to his article - Tape Manifesto for the 21st Century (pdf) - (published in December 2015).

Among other things Fred says - "The shift in the storage landscape is underway as high performance data finds its way onto flash SSD and lower activity and archive data migrate to modern tape. As a result, the amount of data stored on HDDs is facilitating a "storage squeeze play""... the article (pdf)

Editor's comments:- Among other things Fred Moore managed the engineering of early enterprise SSDs for StorageTek in 1978. I was curious to see what he's writing about nowadays.

the state of tape in 2015

Editor:- January 20, 2015 - 2 interesting ideas about tape backup were discussed in a new blog - Still Loving Tape in 2015 by Jon Toigo on
  • Google still relies on tape backup. Jon Toigo says "Google has conceded publicly that its email service would have been non-recoverable in an outage that occurred last year had it not been for good old tape."
  • An important reliability factor in tape drives is the "Carbon Robot (the operator, that is)" due to the risk of damage which occurs when a tape is dropped on the floor. - Jon Toigo says that's what led to a new startup - ShockSense Enterprises - which by using sensors - can report to an enabled storage system that the drive is suspected of having been damaged. the article

will flash save tape? - flape

Editor:- November 9, 2012 - "Flape" - flash cached tape archive - is a new word discussed in a blog - Flape and Floud - by Steve Kenniston - The Storage Alchemist who says "Over the last two decades I have been in this business, tape has been killed off more than a bad guy in a James Bond movie..."

Editor's comments:- It's interesting to think that flash tiering and caching might extend the life of tape libraries. But in the distant future (2020 timescale) I expect that anyone still using tape cartridges might find when they open them - they have archive SSDs inside emulating the tape media. It was already done long ago for floppy drives. But even SSDs become EOL and cause problems for those trying to support legacy systems.

university researchers compare SSD and tape archives

Editor:- November 1, 2011 - a recent white paper - Using Storage Class Memory for Archives with DAWN, a Durable Array of Wimpy Nodes (pdf) - written by academics at University of California, Santa Cruz and Stanford University - and published under the auspices of the Storage Systems Research Center compares the long term cost and reliability of solid state archival storage and traditional media - such as tape.

"Our investigation has shown that storage class memories have many characteristics favorable to digital archiving. Despite this, more investigation in several areas is needed in order to fully understand the tradeoffs and feasibility of a storage class memory approach." the article

Is there a Future for Tape Backup? - revisited in a roundabout way

Editor:- October 25, 2011 - Is there a Future for Tape Backup? is an interesting review of this subject from Steven Golden from the perspective of what he calls a "programmer" oriented blog called Code and Butter

His blogs - which I just discovered for the first time - are well thought out and neatly formatted too. If you ever want to start your own WordPress blog - you can learn from his pages. It's lucky for me that standards for web pages were a lot lower when I got started.

SEPATON article on tape dinosaurs

Editor:- August 30, 2010 - Jon Mills, Director of European operations at SEPATON recently published an article - Tape - the T Rex of backup? - which provides anthropological comparisons between tape libraries and these popular creatures.

I guess it takes one soon-to-be-extinct dinosoar to recognize another. My own view is that hard disk based backup will eventually be replaced by solid state backup. So enjoy chewing the spinning magnetic leaves while they last.

Overland launches tape library patent suit

Editor:- August 20, 2010 - Overland Storage announced it is suing BDT AG - for alledged infringement of tape library related patents.

"We owe it to our shareholders and our customers to protect the technology investments we have made throughout the years," said Eric Kelly, President and CEO of Overland Storage. "We believe our technologies are one of the driving forces behind the demand for tape storage solutions today. Our patented technologies allow us and others to bring to market products and solutions that are more reliable, more secure and more efficient."

Editor's comments:- Tape library market revenue has halved in the past 10 years. (2000 tape library revenue was $2 billion according to Freeman Reports .) But that strengthens the case for defending each remaining slice and crumb.

New fitness service for old tape libraries

Editor:- July 12, 2010 - Crossroads Systems today announced a new service for users of tape libraries.

The library overview analysis service provides comprehensive analytics on the health, performance and utilization of tape libraries and helps users identify the any sources of inefficiencies which can otherwise lead to backups exceeding allocated time windows.

"Rather than tossing out perfectly good media, storage administrators can avoid unnecessary costs and headaches by viewing the precise status and health of their environment," said Elaine Pleshek, senior product manager at Crossroads Systems. "It's a service that pays for itself. By gaining a reliable tool that continually diagnoses operational backup errors, organizations can experience impressive performance improvements."

Re tape's protracted demise

Editor:- June 16, 2010 - How tape dies is the latest blog from StorageMojo, Robin Harris.

Tape market's body is still twitching - so it's not technically a corpse (yet) - but the life signs are getting smaller.

Overland expands LTO-5 support

Editor:- April 21, 2010 - April 21, 2010 - Overland Storage today announced expanded support for LTO-5 (tape) technology (available from May 1, 2010) across its entire line of NEO Series products - which offer backup storage capacity up to 76TB and support for disk-based backup. asks - Could TB HDDs be given away free?

Editor:- June 10, 2010 - a new article published today on asks - Could terabyte hard drives ever be given away free?

I think could that be a really good business strategy to prolong the life of the HDD market beyond 2016.

And you thought the outlook was shaky for the tape market... the article

reaching for the petabyte SSD

Editor:- March 16, 2010 - previewing the final chapters in the long running SSD vs HDD wars - today published an industry changing new article - SSDs - reaching for the Petabyte.

What will the PB SSD look like? When will it appear? What technology problems do SSD designers have to solve to get there? What about the storage architecture that the PB SSD fits into? How much electrical power will it consume? And... you may be curious - how much will it cost?

All these questions and more - are discussed and answered in this article which - I anticipate - will inspire product managers and company founders to create completely new types of SSDs. the article

New Integrity Tool for Old Tape Archives

Editor:- January 18, 2010 - Crossroads Systems today announced details of ArchiveVerify - a new monitoring option for its ReadVerify Appliance that safeguards the future readability of data backed up on tape.

"In our experience, the Achilles' heel of a data recovery strategy is often the uncertainty of the data's readability, and this single point of failure can render then entire restore process useless," adds Bernd Krieger, Managing Director, at Crossroads Europe.

Editor's comments:- Crossroads was originally a specialist in the SAN router business. In recent years it has done a lot of work in the area of storage reliability. I've read lots of their whitepapers which describe their research and products addressing data integrity. Although there has been a historic trend for users to migrate away from tape to disk backup - many super users of huge tape libraries (with the biggest archives) will be the last to migrate away - due to logistics and cost. It's those kind of users who can benefit most from automated tools or services which increase the data integrity they achieve and cut down media waste and unrecoverable events.

$9 million Funding Round for flash SSD Enabled SAN Backup

Editor:- November 18, 2009 - Axxana announced it has secured $9 million Series B investment led by Carmel Ventures.

Axxana's existing investors, Gemini Israel Funds and the serial entrepreneur Moshe Yanai, also participated in the round.

The funds will be used to accelerate the adoption of The Phoenix System - the first "Black Box" Enterprise Data Recorder which was demonstrated at EMC World in May 2009.

"Axxana's EDR brings a disruptive solution that is well poised to transform the entire storage replication market and create a whole new category within it," said Ronen Nir, Partner at Carmel Ventures. "We are impressed with Axxana's strong founding team and their achievements so far, including impressive endorsement by leading storage vendors worldwide."

Editor's comments:- Axxana's solution is a lossless data recovery system which sits on the SAN and records data into a rugged flash SSD-enabled, locally situated, data survival box. Although Axxana talks about it "complementing" other types of data protection - such as offsite / online backup my gut feel is that if the product shows itself to be usable and reliable in a wide range of environments - it will set a new standard for backup which will supercede anything possible with rotating disk backup systems or tape.

The clearest explanation is in Axxana's datasheet (pf).

BakBone Wakes Up to Disk Backup

Editor:- September 16, 2009 - BakBone Software today announced it will change its focus from traditional tape-based data protection solutions to disk-based technology with new products to be launched soon.

FalconStor Claims Fastest Deduped Backup
Editor:- June 1, 2009 - FalconStor Software today claimed that it now delivers the fastest backup and deduplication time in the industry.

Using a 100TB test bed connected to a single cluster of 2 FalconStor VTL nodes the total time to backup and deduplicate data was under 14 hours, yielding an average of 2GB/s per second.

Physical tape production can be achieved directly through 4Gbps Fibre Channel links by exporting tapes from FalconStor VTL to the physical tape library without using a separate media server. All hardware components used for the performance test are commonly available standard parts, including standard Linux-based servers and low-cost SATA-based storage subsystems.

Editor's comments:- Record Breaking claims are often hostage to editor research. We've certainly run stories about faster backup and restores before - but they didn't include dedupe. Let's see if this one passes the test of reader scrutiny.

Tandberg's Tape Bust

Editor:- April 27, 2009 - Tandberg Data has filed for bankruptcy and today announced details of its restructuring plan.

There's no surprise here. The current recession has merely brought forward an inevitable event. Although Tandberg had acquired and licensed various disk backup technologies it remained culturally wedded to tape.

I've chronicled the transition of the backup market from tape to hard disk and in some ways it's similar to what's been happening in the hard disk market versus flash SSD space. But the SSD market is more complicated - because whereas slow cheap SSDs replace hard drives, fast expensive SSDs replace server CPUs.

As with hard drives, the highest capacity tape libraries will remain spinning the longest. Nothing stays the same in the storage market for long. Looking ahead at the next 10 years SSDs will replace hard drives in enterprise backup systems too.

But let's get back to today's news from Tandberg Data, whose CEO, Pat Clarke, said - "The operations of the Tandberg Data subsidiaries will continue to operate in this new structure, with a much reduced debt burden. The difficult steps we are taking now will enable us to build a company that can be successful in providing data protection solutions and support to our valued customers, suppliers, and business partners for a long time to come"

Trawling back through gone-away / bust storage companies list (where the score now stands at 490 BTW) a search for "Tandberg" reveals it had previously acquired these companies:- LAND-5, InoStor, Exabyte and Computer Design Group.

Spectra Dims Sun's Lights at NASA Ames

Editor:- April 20, 2009 - Spectra Logic today disclosed that it has ousted Sun in a big tape library installation - following a 9 month evaluation.

Spectra recently installed 2x T950 tape libraries which together offer approximately 20,000 data storage slots and up to 32 petabytes of storage capacity, with data compression.

By replacing multiple, legacy Sun/STK 9310 silos with Spectra Logic technology, NASA Ames has freed more than 1,400 square feet of valuable data center floor space.

Editor's comments:- according to Sun's website, its own suggested replacement for the 9310 is the SL8500 Modular Library. So I guess that's the product (or the service offering) which Spectra beat in this case.

Sun Proposes Standardizing Tape Storage Encryption

Santa Clara, CA - February 17, 2009 - Sun Microsystems today announced an open source initiative for removable storage encryption in Solaris environments.

This is based on the key manager which Sun already uses in some of its Tape Libraries. See also:- Storage Security

Spectra Libraries will Log Tape Health Metrics

SNW, ORLANDO, FL - April 8, 2008 - Spectra Logic announced details of its soon to be released new Media Lifecycle Management software for its tape library customers.

MLM will reduce backup failures by tracking more than 30 pieces of information about individual LTO tapes and logging this on on the tape's built in flash chip. Information such as: born-on date, number of reads and writes, error rate, media quality, date of last access, application usage, encryption information, cleaning log and remaining capacity are tracked. MLM and BlueScale are compatible with all major backup applications. ...Spectra Logic profile

Editor's comments:-
already past the decline and now in the fall years of the tape library market it looks like customers will get all kinds of useful information and services which they probably would have liked to have before. This sounds similar in concept to the SMART logs in hard disks and SiSMART in SiliconSystems' flash SSDs.

Fujifilm Launches Wireless Backup Tape Tracker

VALHALLA, N.Y. - March 26, 2008 - Fujifilm today announced the immediate availability of the Fujifilm Tape Tracker, a wireless tool to help data managers increase security of data by tracking in real-time the location and status of sensitive removable media cartridges while in transit.

The Fujifilm Tape Tracker (patents pending) is designed within a 0.5" tape cartridge format, enabling it to fit snugly and discreetly inside nearly any tape media case. The Fujifind application uses the information, tracking, geo-fencing and notification capability of SC-Integrity's LoJack InTransit monitoring solution.

"The tremendous feedback we received from customers when we introduced this concept last year made clear - there is a significant desire to maintain visibility and control over removable media during shipment from one location to another," said Daniel Greenberg at Fujifilm Recording Media. "The ability of tape to store large quantities of data in a cost effective, energy efficient, removable format make it a preferred medium to backup and archive critical business data. The Tape Tracker gives power back to the data managers to maintain a chain of custody for these assets as they move between data center backup, vault or disaster recovery destinations." ...Fujifilm profile

Expansion Modules Push Tape Library Past 2 Petabytes

SIMI VALLEY, Calif - February 20, 2008 - Qualstar Corp today announced that the MEM ll (Memory Expansion Module), is now available on its popular XLS-812300 tape library.

Tape Libraries on

from the glory days of the past, surviving VTL and looping onwards towards flash

by Zsolt Kerekes, editor -

Believe it or not - back in 1999 this tape library page was one of the most popular destinations on this website.

A year later - in 2000 - I published the first online directory dedicated to enterprise disk to disk bakup (as we called it in those days) and it's been called many things along the way since - D2d, VTL, cloud...

Anyway you're still using tape. You may not like it - but due to massive amounts of data, legacy architectures, etc etc - you're still using tape libraries. If so - I've got some surprising news for you...

You may be able to skip the transition to hard disk backup!

If you're a Huge data owner and still using tape - I suggest you read my roadmap to the petabyte SSD article. Even if hard drives become free - they won't scale to a petabyte in 1U - whereas solid state storage will. I expect SSD libraries will be the next thing in your future. But you may still got to hang in there for another 5 years of managing all those tape cartridges in the meantime.

this way to the Petabyte SSD
In 2016 there will be just 3 types of SSD in the datacenter.

One of them doesn't exist yet - the bulk storage SSD.

It will start to replace the last remaining strongholds of hard drives in the datacenter due to its unique combination of characteristics, huge storage density, low running costs and operational advantages.

Bulk storage SSDs will displace the last remaining hard drives in the enterprise server market by 2020 - even if the price of a new hard disk drops to zero and enterprise HDDs are given away free!
click to read the article -  reaching for the petabyte SSD - not as scary as you may think ... The new business and architectural models of the datacenter - how we get from here to there - and the technical and problems which will need to be solved - are just some of the ideas explored in this visionary article.
