Simultaneous archiving solution
The customized mobile cart onboard Mermaid Sapphire
comprised two redundantly congured solutions each
containing an HP ProLiant DL rack-mounted server, two
rack-mounted HP LTO-5 Ultrium 3000 Tape Drives with
the DNA Evolution™ X400-48 LTFS solution. StorageDNA
equipped Digital Pictures’ post-production facility with
an HP MSL 4048 Tape Library to process the HP LTO-5
tapes with DNA Evolution™ software, creating sequence
restores with the HP tapes acting as low-cost nearline disks.
The production team ran four archives simultaneously,
operating at speeds exceeding 500 MB per second. Each
system generated two LTO copies, one for conform and
another for a disaster recovery archive.
“As raw footage came onboard, the production team o-put
it to LTO tape and simultaneously created a low-resolution
copy,” says Chakravarty. “After they’d edited the
low-resolution copy, they found the right tapes using an edit
list and automatically pulled out the correct media. Digital
Pictures had 24 LTO-5 1.5 TB tapes online, functioning like
nearline storage. Speed and accuracy are paramount during
this process as it’s producing a master recording.”
Intelligent restores and conforms
The HP LTO-5 Ultrium 3000 Tape Drives and HP MSL 4048
Tape Library with the StorageDNA LTFS solution also scale
well. There is no limit to the number of stored LTO tapes.
Armed with an edit list, the solution can identify the tapes
required, plug them into an auto-robot and restore quickly
and accurately.
“The performance and price benets are pretty amazing, too.
You can get 100 TB of LTO-5 tape for under $4,000,” adds
Chakravarty. “While recently producing a TV series with the
HP hardware running DNA Evolution™, the estimated savings
amounted to $107,000.”
Unlike other solutions, the HP-StorageDNA solution
performs intelligent restores and conforms. If a producer is
instructed to shoot video tapeless, using LTO tape with LTFS
technology is a wise decision as several well-documented
hard drive failures have convinced many that storing drives
on shelves is unacceptable.
“The alternatives to LTO will have a hard time keeping up as
le-based shooting becomes even more prevalent. Using LTO
tape enabled by LTFS technology and intelligent software
solutions such as StorageDNA will become increasingly
popular across the industry, and we’re convinced it will be
the defacto standard for archiving within four to ve years.
Meanwhile, we’re all looking forward to seeing Mr Cameron’s
new documentary,” concludes Chakravarty.
