Tape libraries 'outpace many networks'
18 Aug 2008
Many storage systems are limited in speed not due to the target medium of tape, but due to the infrastructure which transmits data to it, it has been asserted.
Rick Cook writes for SearchStorage of the limiting factors which apply to the maximum performance of any given network - the speed at which data is carried and the rate at which it may be written.
He claims that "many libraries can absorb data faster than many networks can transmit it", despite the interruption to storage that may occur while tapes are being changed.
Mr Cook adds that deduplication could be a means of accelerating the process due to the fact that "if you use something like data deduplication, your backups may be a lot smaller".
His comments follow assertions from Jim Damoulakis in ComputerWorld that deduplication is being more widely implemented and is being used to address primary network traffic and not just archived data..
