Tape storage capacity plays important role as data increases

As the amount of new data created is set to hit the multiple-zettabyte level in the coming years, where will we store it all?

With the release of LTO-8 and recent reports that total tape storage capacity continues to increase dramatically, tape is a strong option for long-term retention. But even tape advocates say it’s going to take a comprehensive approach to storage that includes other forms of media to handle the data influx.

Tape making a comeback?

The annual tape media shipment report released earlier this year by the LTO Program showed that 108,000 petabytes (PB) of compressed tape storage capacity shipped in 2017, an increase of 12.9% over 2016. The total marks a fivefold increase over the capacity of just over 20,000 PB shipped in 2008.

LTO-8, which launched in late 2017, provides 30 TB compressed capacity and 12 TB native, doubling the capacities of LTO-7, which came out in 2015. The 12 TB of uncompressed capacity is equivalent to 8,000 movies, 2,880,000 songs or 7,140,000 photos, according to vendor Spectra Logic.

“We hope now [with] LTO-8 another increase in capacity [next year],” said Laura Loredo, worldwide marketing product manager at Hewlett Packard Enterprise, one of the LTO Program’s Technology Provider Companies along with IBM and Quantum.

The media, entertainment and science industries have been traditionally strong users of tape for long-term retention. Loredo pointed to more recent uses that have gained traction. Video surveillance is getting digitized more often and kept for longer, and there is more of it in general. The medical industry is a similar story, as records get digitized and kept for long periods of time.

The ability to create digital content at high volumes is becoming less expensive, and with higher resolutions, those capacities are increasing, Quantum product and solution marketing manager Kieran Maloney said. So tape becomes a cost-efficient play for retaining that data.

Tape also brings security benefits. Because it is naturally isolated from a network, tape provides a true “air gap” for protection against ransomware, said Carlos Sandoval Castro, LTO marketing representative at IBM. If ransomware is in a system, it can’t touch a tape that’s not connected, making tapes an avenue for disaster recovery in the event of a successful attack.

“We are seeing customers come back to tape,” Loredo said.

Tape sees clear runway ahead

“There’s a lot of runway ahead for tape … much more so than either flash or disk,” said analyst Jon Toigo, managing partner at Toigo Partners International and chairman of the Data Management Institute.

Even public cloud providers such as Microsoft Azure are big consumers of tape, Toigo said. Those cloud providers can use the large tape storage capacity for their data backup.

However, with IDC forecasting dozens of zettabytes in need of storage by 2025, flash and disk will remain important. One zettabyte is equal to approximately 1 billion TBs.

“You’re going to need all of the above,” Toigo said. “Tape is an absolute requirement for storing the massive amounts of data coming down the pike.”

It’s not necessarily about flash versus tape or other comparisons, it’s about how best to use flash, disk, tape and the cloud, said Rich Gadomski, vice president of marketing at Fujifilm and a member of the Tape Storage Council.

The cloud, for example, is helpful for certain aspects, such as offsite storage, but it shouldn’t be the medium for everything.

“A multifaceted data protection approach continues to thrive,” Gadomski said.

There’s still a lot of education needed around tape, vendors said. So often the conversation pits technologies against each other, Maloney said, but instead the question should be “Which technology works best for which use?” In the end, tape can fit into a tiered storage model that also includes flash, disk and the cloud.

In a similar way, the Tape Storage Council’s annual “State of the Tape Industry” report, released in March, acknowledged that organizations are often best served by using multiple media for storage.

“Tape shares the data center storage hierarchy with SSDs and HDDs and the ideal storage solution optimizes the strengths of each,” the report said. “However, the role tape serves in today’s modern data centers is quickly expanding into new markets because compelling technological advancements have made tape the most economical, highest capacity and most reliable storage medium available.”

LTO-8 uses tunnel magnetoresistance (TMR) for tape heads, a switch from the previous giant magnetoresistance (GMR). TMR provides a more defined electrical signal than GMR, allowing bits to be written to smaller areas of LTO media. LTO-8 also uses barium ferrite instead of metal particles for tape storage capacity improvement. With the inclusion of TMR technology and barium ferrite, LTO-8 is only backward compatible to one generation. Historically, LTO had been able to read back two generations and write back to one generation.

“Tape continues to evolve — the technology certainly isn’t standing still,” Gadomski said.

Tape also has a clearly defined roadmap, with LTO projected out to the 12th generation. Each successive generation after LTO-8 projects double the capacity of the previous version. As a result, LTO-12 would offer 480 TB compressed tape storage capacity and 192 TB native. It typically takes between two and three years for a new LTO generation to launch.

In addition, IBM and Sony have said they developed technology for the highest recording areal density for tape storage media, resulting in approximately 330 TB uncompressed per cartridge.

On the lookout for advances in storage

Spectra Logic, in its “Digital Data Storage Outlook 2018” report released in June, said it projects much of the future zettabytes of data will “never be stored or will be retained for only a brief time.”

“Spectra’s projections show a small likelihood of a constrained supply of storage to meet the needs of the digital universe through 2026,” the report said. “Expected advances in storage technologies, however, need to occur during this timeframe. Lack of advances in a particular technology, such as magnetic disk, will necessitate greater use of other storage mediums such as flash and tape.”

While the report claims the use of tape for secondary storage has declined with backup moving to disk, the need for tape storage capacity in the long-term archive market is growing.

“Tape technology is well-suited for this space as it provides the benefits of low environmental footprint on both floor space and power; a high level of data integrity over a long period of time; and a much lower cost per gigabyte of storage than all other storage mediums,” the report said.

Hi, sorry for delay coming back to thread I didn’t see the notification until now.

Just 2 quick questions, is the keyboard wireless or wired?

Due to distance, I’d only be able to collect on a weekend ( my wife and eldest work most nights , and I’d rather not take my youngest on a 180 mile round trip if I can help it ) would the weekend after be any good? Or is that to long to wait for sale ( I understand if it is ) I assure you we won’t let you down or back out

Could you let me have the first part of your postcode so I can workout the distance from Gloucester, I’m thinking approx 90 each way

As you can see I need the Mac to help count as that was 3 questions lol

Thanks

Apple iOS 12 USB Restricted Mode to foil thieves, law enforcement

A security feature that had popped up in beta versions of Apple’s iOS software appears to be coming in earnest as part of iOS 12, and it will protect devices against anyone trying to unlock them via USB.

USB Restricted Mode is described in the iOS 12 settings as the option to enable or deny the ability to “unlock [an] iPhone to allow USB accessories to connect when it has been more than an hour since your iPhone was locked.” In practice, this means a device will require a passcode unlock in order to connect any Lightning-to-USB accessory after the one-hour time limit has passed.

Apple didn’t mention USB Restricted Mode during the keynote at its Worldwide Developers Conference on Monday, but developers saw it in the iOS 12 preview, which was released that same day. The setting is on by default and covers any type of security on an iOS device — Touch ID, Face ID and passcode.

Experts noted USB Restricted Mode will protect users’ data if a device is stolen, but it will also deny law enforcement from using unlocking services from companies like GrayKey and Cellebrite — the latter of which was rumored to have helped the FBI unlock the San Bernardino, Calif., shooter’s iPhone.

Earlier tests of USB Restricted Mode had allowed for a one-week time limit, spurring GrayKey to reportedly alert customers of this feature when it surfaced in the iOS 11.3 beta, according to internal email messages obtained by Motherboard. A one-hour time limit could effectively make it impossible for customers to get the device to a company like GrayKey in time to gain brute-force access.

Rusty Carter, vice president of product management at Arxan, based in San Francisco, said USB Restricted Mode “is really about increasing the security of the device.”

If the device is vulnerable to brute-force attacks via wired connection, other security features, like being able to wipe the device after 10 unsuccessful authentication attempts, are rendered useless.

“If the device is vulnerable to brute-force attacks via wired connection, other security features, like being able to wipe the device after 10 unsuccessful authentication attempts, are rendered useless … they are effectively a false sense of security,” Carter wrote via email. “Effectively, any data is vulnerable, unless the individual app developer has done the right thing both to secure and encrypt user data and require more than stored credentials or identity to access the data with their app, which is rarely the case today.”

John Callahan, CTO of Veridium, based in Quincy, Mass., said, as a developer, his initial reaction to USB Restricted Mode was, “Great, now I’ll have to unlock the phone every time I go to debug a mobile app with Xcode.” But he later realized it could have protected a lot of stolen devices if it had been implemented in an earlier version of iOS.

“USB Restricted Mode in iOS 12 a big win for users, because we are keeping more personally identifiable information on our mobile devices, including healthcare, identification and biometric data. Our phones have become our digital wallets, and we expect a maximum level of privacy and convenience,” Callahan wrote via email. “Android devices, ironically seen as less secure, have long required unlocking when connected in USB Debug mode. In many ways, Apple is playing catch-up with respect to physical device security.”
