Spectra Logic makes the only tape-storage systems that automatically check the media and the data on tape throughout the storage life of the data.
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. Digital tape
system provider Spectra Logic is taking away that uncertainty.
Colo.-based company on March 21 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.
note: The company is not charging a dime for it.
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
DIV comes with
BlueScale 11.3, the latest version of the software-management platform that
runs all of Spectra Logic's tape libraries. 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.

archiving all the way up to the processing of large data sets for television
stations, video creation studios (including computer-generated animation) and
data integrity verification is increasingly becoming a data center requirement
for highly valued data solutions," Rector said. "Data Integrity
Verification reduces risk, ensures enduring access to archived data and is fast
becoming a data center requirement."
Verification includes three levels of automated validation, Rector said:
Flow of Data Not Slowing Down
Checks newly imported tapes to ensure they are ready to use; for example,
it classifies them as in good health, generationally compatible, or not
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. Along with PostScan, rapid or
gradual media degradation is tracked in the library's flash memory SQL
database and reported to users.
Automatically verifies the physical tape cartridge and the integrity of
all of the data stored upon it. 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.
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
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.
organizations need smart strategies and tools that deliver extreme storage
efficiencies while meeting stringent data reliability and availability
requirements. Spectra Logic's enterprise capabilities and tape technology
innovations, including Data Integrity Verification, are excellent examples of
Tape Remains a Mainstay in Data Centers
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.
Rector said, "We have customers who are using our digital tape systems for
their Tier 1 storage."
While that may
sound outrageous off the top, one has to consider the use cases connected with
the big systems Spectra Logic makes. While digital tape certainly would
not be a Tier 1-type storage to use for high-transaction/database-type
applications, for a television station or video-creation studio, it would be
front and center.
Verification is available immediately for no charge on all Spectra Logic tape
libraries, including the Spectra T50e and T120, the Spectra T-Series Mid-Range
T200, T380 and T680, and the enterprise class T950 and T-Finity, Rector said.
