For years, disk vendors have heralded the death of tape. Will tape vendors soon be saying the same for disk?
Couglin notes that NVM Express, an industry trade group working on standards for storage devices such as SSD, announced a network fabric specification to allow thousands of solid state drives to be shared via a fabric rather than host specific using PCI Express.
He also shares that the LTO Consortium and SNIA named the LTFS specification an International Organisation for Standardisation (ISO) and International Electrotechnical Commission (IEC) standard (ISO/IEC 20919:2016).
Tom reminds us that published specifications help create an open industry where vendors can create solutions that interoperate. Standards then drive adoption.
NVM already enables mission critical applications to run at blazing speed. LTFS will enable tape to hold data in a file system with automatic copies for backup and instant disaster recovery.
NVM storage outperforms hard disks for speed, reliability and environmental cost. Tape outperforms hard disks for reliability, cost per GB and environmental cost.
Combine the two technologies in a Data Centre and the long term viability of hard disks comes into question—while LTFS still has a long life ahead of it. Tom writes:” LTFS is a technology that will make the use of tape for long-term, affordable storage easier and more attractive.”
What are your thoughts on how LTFS will impact the industry (and how it already is)? Leave a comment to share your thoughts.
