26 TVBEurope Forum Archiving & Storage Herzog: In general, the Matthew Rehrer, Harmonic Fanichet: Indeed, multi-screen
is all about transcoding content in multiple formats from TV, cable TV, video-on-demand to tablets and phones. This means more files, more versions, more assets to be stored and managed over time. Février: Definitely. You have
to be able instantly to generate a lot of different file resolutions when you retrieve your content from archive to deliver it to as many screens as possible. The speed of the process is also important.
proliferation of low-cost displays has meant that our customers are producing more and more content to fill those displays. This drives a voracious appetite for more and more storage capacity. Luckily, drive sizes are increasing to support this appetite, with 4TB drives now producing over 50 TB of RAID-6 protected space in a single 16 drive RAID array. Hoggarth: Any new version of a media file that has to be stored rather than regenerated will have some impact on the overall storage requirements, but in practice it has relatively little impact on the archive. The streams tend to be relatively small in data terms, and are usually located on specific storage tiers on separate systems. A far greater impact has resulted from the use of higher resolution production and distribution formats. Rehrer: A lot of customers
have seen the future and realised that with the right storage and archive system, they can repeatedly monetise their large content libraries.
Through multiscreen services, content gains new life, and the archive is the place in which the media company can find valuable material, transcode it, and deliver it to new paying customers.
What is more popular — spinning disk technology or solid-state flash memory?
Dymond: Spinning platters are still the strongest storage disk based media for broadcasters and for the majority of file based movement and access requirements. The usage of solid state flash memory is increasing in the database layers of organisations due to the additional read/write overheads of non-continuous data packets
and user facing content delivery caches — where seek time becomes more critical. Fanichet: We are pretty
agnostic in terms of technology used by our customers to store digital content. However, another
key trend is that customers are mixing the type of technology used in their digital workflows. This is true for storage technologies, for instance, Raid- based disks, flash or SSDs, cloud or LTO/LTFS tape. This is also
