Fujitsu Storage: ETERNUS LT Family Now Supports LTO-8


Enterprises are increasingly under cyberattack, which can lead to data loss or corruption. The latest threat is ransomware, which became one of – if not the – most popular cyber-attack schemes in recent years, with adversaries invading infrastructures, encrypting critical data and not 'releasing' them unless and until users pay the equivalent of thousands of dollars in crypto-coins for the unlock keys. As attacks of this nature become more sophisticated each day, organizations that are locked out of their data face a trail of damage that can take weeks or months to repair.

To counter this type of attack, the so-called "3-2-1 rule" is more relevant today than it has ever been: At any point in time, IT departments must at least keep three copies of backup data, store two of them on different storage media, and one offline. Especially if said data is business- or mission-critical, keeping an offline copy (at best one that's encrypted itself) is a surefire way of obviating the risk of online attacks. And even today, the easiest and most affordable way to get there is to deploy one or more tape systems that help organizations establish a regime of tiered data retention.

Fujitsu's ETERNUS LT family of tape systems provide a solid basis for highly-scalable and cost-efficient backup solutions. In their latest iteration, these systems – from the cost-effective, entry-level ETERNUS LT20 to the massively dense ETERNUS LT260 (pictured above) that digests up to 16.8 PB of information – now support the latest LTO-8 technology, which is suitable for a variety of usage scenarios, including long-term data retention, archiving or disaster recovery alongside regular offline backups. What's more, the LTO-8 standard, as supported by the eponymous LTO Consortium, also enables IT departments to meet ever-tightening global data protection and compliance requirements:

  • The capacity per tape increases to 12 GB native and 30 GB compressed – twice as much as could be stored on previous LTO-7 media.
  • Transfer rates clock in at up to 360 MB/s native and up to 750 MB/s compressed – considerably faster than the roughly 150 MB/s achievable with regular 7,200 RPM HDDs.
  • LTO-8 supports hardware-based 256-bit AES encryption, which is currently regarded as the "gold standard" in cryptography, since there are no known practical attacks that could be successfully carried out. In other words, even if an attacker managed to get his hands on a physical copy, all he would see is a random string of bits and bytes, whereas authorized users can easily recover and access the information.
  • As per usual, the LTO-8 standard is backwards compatible with its predecessor, meaning it can read from and write to LTO-7 media.

Together, these capabilities make it much easier than before to create secure data backups that can be kept offline and help maintain the integrity and accessibility of critical data even in the face of ransomware attacks or other criminal acts.

All ETERNUS LT family products will support LTO-8 from May 31, 2018 across all regions. As an extra, the ETERNUS LT260 model can also generate and manage data encryption keys within its own tape library, saving users the cost of using backup software or an additional server. What's more, Fujitsu will also introduce support for LTO-8 to all three models in its ETERNUS CS lineup of disk-based data protection appliances.
