Spectra Logic’s Rector said, “We have customers who are using our digital tape systems for their Tier 1 storage.” Spectra Logic’s enterprise capabilities and tape technology innovations, including Data Integrity Verification, are excellent examples of this.” Tape remains a mainstay in data centresĭigital tape, though often described as obsolete by disk and solid-state storage makers, has been a mainstay of IT storage for two generations and shows little indication of leaving the enterprise scene anytime soon. “Consequently, organisations need smart strategies and tools that deliver extreme storage efficiencies while meeting stringent data reliability and availability requirements. “We expect worldwide tape archive capacity to grow more than sixfold over the next five years – from just under 13 exabytes in 2010 to over 81 exabytes by 2015, driven by both new digital content and extended storage timelines,” Peters said. The amount of data stored on tape continues to surge as massive and growing digital-archive demands compel users to seek practical and economical ways to address escalating data volumes, senior analyst Mark Peters of Enterprise Strategy Group said. As with PreScan and QuickScan, the PostScan process is performed by the library and is independent of the backup application normally used to read and write data to the tape. PostScan: Automatically verifies the physical tape cartridge and the integrity of all of the data stored upon it.Along with PostScan, rapid or gradual media degradation is tracked in the library’s flash memory SQL database and reported to users. QuickScan: Quickly and immediately verifies the backup and archive data was successfully written to tape with a rapid single pass from the beginning of the tape to the end of the first track.PreScan: Checks newly imported tapes to ensure they are ready to use for example, it classifies them as in good health, generationally compatible, or not write-protected.“Data Integrity Verification reduces risk, ensures enduring access to archived data and is fast becoming a data centre requirement.”ĭata Integrity Verification includes three levels of automated validation, Rector said: “Integrated data integrity verification is increasingly becoming a data centre requirement for highly valued data solutions,” Rector said. Spectra Logic makes various sizes of digital tape systems that range from small-business archiving all the way up to the processing of large data sets for television stations, video creation studios (including computer-generated animation) and scientific applications. As a result, it is the only tape storage system that automatically checks the media and the data on tape throughout the storage life of the data, Rector said. Spectra Logic’s BlueScale Data Integrity Verification for tape libraries is an industry first, CTO Molly Rector told eWEEK, and an important long-term data-reliability feature that ensures data written to tape is retrievable now and for years to come.ĭIV comes with BlueScale 11.3, the latest version of the software-management platform that runs all of Spectra Logic’s tape libraries. One other note: The company is not charging a dime for it. The Boulder, Colorado-based company on 21 March said it is offering a new feature called Data Integrity Verification across its complete line of T-Series tape libraries – from small and midsize business systems to petabyte-scale enterprise systems. Digital tape system provider Spectra Logic is taking away that uncertainty. As IT technologies come and go, storage administrators who wonder whether data stored in digital tape archives will still be usable and/or easily accessible 20, 30 or 50 years from now don’t have to think about that anymore.
