I hear a bunch of budgies squeakin' in the background..... :) Awesome to see this in operation with the lid off--I didn't know LTO ran at such a high tape speed!
Oh man the 2007 memories of getting crates full of these for our daily, weekly & monthlies and taking half an hour to swap 'em all out each time are flooding back 😊 thank you!
I was a computer operator in the USAF (76-80) and watching the tape spin was reminiscent of the old 9-track tape dives we had on the Burroughs 3500 & 4700 mainframes. Good times.
You might have known my dad. Master Sargent Gary Watters, Site R 80-85 near Camp David and Maxwell Gunter Montgomery Al 74 to 80. Worked on Burroughs and IBM mainframes
In my last job, we were using LTO-6 cartridges for the monthly backup of the 4TB HDD(one cartridge per HDD), and due the only one hole, I thought that the central tape cylinder were split in half, and the tape did a 180 degree turn, so the tape would never get outside of the cartridge, like the cassettes tapes, seeing this was awesome, thank you, but now I'm 1.000.000% more afraid of something going wrong =P
The outside final of the tape have an metal cylinder connected to it that is the one that is pulled by the drive and goes in the center of the spool of the drive to pull the tape.
Awesome video, but I couldn't see / understand how it unloaded the tape lead. Ive seen a demonstration on a HH drive of a different generation but this one appears to have a very different mechanism. Id love to see the load and unload wind up in action close up, and with slow motion if possible. Very cool drives. I just got LTO 4.
Jon - If it runs out of data, it stops, then rewinds a bit, - if by now it has some data to write, it fast forwards searching for where it previously stopped writing, once detected it switches back to write. So yes, it goes back and forth if the data stream is too slow, hence the term 'shoe-shining'.
Haha - it was so delicately done though. Runs at super high speed until it gets near the end, then slows to a sprint, then to a jog, then to a slow stretch for that last rotation or two.
6GB of what ? Various files ? Of what size? Is commpression on ? Good to see internals working very few moving parts no wonder it killed SAIT and DAT with helical scan. thanks
800GB? The tape is a lie! (Manufacturers always label the tapes with their 'compressed' capacity, a very optimistic estimate. You're only guaranteed half that.
Well, our Sony Ultrium 6 of 6.25TB LTO-6 cartridges really had that capacity, since we could backup one entire HDD to a cartridge without any problem(using an old version of Backup Exec)
@@HerrRussoTragik No they don't... They have a 2.5TB capacity without compression and 6.25TB with 2.5:1 compression. I've seen LTO go over the rated compression before so you might even manage to fit more than 6.25TB on a single LTO-6 tape but it completely depends on what type of data you are writing. If you'd send highly compressable data you'd easily reach 3:1 compression, if you'd send more typical data you'll struggle to reach above 1.5:1... The tapes have a 2.5TB capacity, this spec is independent of compression, the capacity of the tape is 2.5TB.

Well, I don't think so, a 4TB backup of a HDD to a LTO-6 of 6.25TB cartridge(not 4TB of data actually) took more or less from 2 to 4 and half hours per HDD, it's limited by the bus speed, while SATA III interface can handle actually 550MB/s, the SAS SFF interface used to "chop" the bitstream, while a drive-to-drive copy of whole 4TB would take more or less 2 hours...
@@HerrRussoTragik That HDD is the bottleneck, the tapedrive will outpace it easily and actually demands a higher performance source. Like you see in this video where the source of data is not fast enough and thus the tapedrive keeps stopping, going back and restarting (shoe-shining) which not only drops performance but also causes a lot of wear on the tape and the tapedrive. You'll want a beefy RAID array or even SSD to feed your tapedrive(s).
@@someguy4915 Not necessarily. LTO-3 has a maximum speed of 80Mb/sec and the minimum speed depends on the drive. tapepower.fujifilmrmd.com/Shared/PDF/knowledgebase/LTO6-TECHFLASH-2015.pdf shows that for this drive (I think it's an HP full height drive) the minimum speed is 27Mb/second. The reason the drive speeds up and slows down (as opposed to shoe-shining) a few times is because it's receiving enough data into its buffer to write a bit faster. You can see this several times in the video. I have an IBM LTO-4 drive, which can write between 30 and 120Mb/sec without shoe-shining and my 5 year old 7200rpm 3Tb Seagate drive can feed it the full 120Mb/s quite happily. In fact my 8Tb WD Red (only 5400 rpm) can do a sustained 210Mb/sec quite happily. Now if only EaseUS ToDo backup would write in chunks of more than 2Gb at a time... If you look at the pdf I linked above, you will see that even the LTO-6 drives can data match as low as 40Mb/sec and have a maximum speed of 160Mb/sec (though the wikipedia page suggests that the standard's maximum speed is actually 160Mb/sec). It's only when we get to LTO-7 and LTO-8 with max speeds of 300 and 360Mb/sec respectively where my cheap single drive wouldn't be able to keep up for sequential access (which backup to tape almost always is, except for LTFS), however with speed matching shoe-shining shouldn't be an issue even then. I think there's either an incredibly slow drive in use here, directly dumping to tape over ethernet, or wiritng of small files rather than sequential reads of a pre-prepared backup set.
The data is written sequentially by file, if you're backing up files. If you're dd'ing an entire drive (aka "imaging the drive") you're also writing sequentially. If you mean the start/stops of the tape, it backs-up then resumes after the last record (aka block), when the host can't feed data fast enough. Also, all modern tape drives are variable speed, and have their own buffer, so they try to avoid this.
@powerChriZ This isn't true since the LTO-5 days and even before that you could skip to specific parts of the tape but the backup software would have to direct this. Since LTO-5 you can skip to specific files, this takes a while (up to 30 seconds) but can be done and doesn't require the entire tape to be read sequentially, after reading a file the tapedrive can also go backwards to read data written before the other file...
@@someguy4915 LTO-5 introduced partitioning (and it was further developed for a larger number of partitions from LTO-6 onwards) which allows a file allocation table to be written to a partition with a map to the location of the files. IBM released LTFS (Linear Tape File System) to work on this basis. It's free, and for LTO-5 and on negates the need for backup software *to a point*. It can be extremely slow and put a LOT of wear on the tape if not used carefully (scanning for thumbnails when browsing directories on the file system for example). Whilst you're not wrong about it not needing to scan the whole tape (as the partition containing the allocation table has pointers to the location of each file) it's still sequential, if you wanted to access just part of a file (like a spreadsheet or a database file) then it would have to read the whole file at once (the allocation table just points to the start/end of the file).
@@nevlabs Even then, it should be able to stream the minimum for data rate matching - I think this is directly dumping small files with something like Z-DATDump rather than a pre-prepared backup set. If it was LTO-5 I'd say it was probably LTFS, but this is only LTO-3. As such, it should be able to write continuously on that drive with anything over 30Mb/sec sustained
@@coreyoilar5651 please try reading again, I wasn't suggesting it was an LTO5 drive. I said it was behaving like a drive working with LTFS. My whole point was that it should only need to feed a minimum of 30Mb/s sustained to avoid that.

Is it reversing a bit every time it runs out of data or just stopping?
Momentum is a thing, so yeah. Just to find the record it left off on though.

What happens if a file is broken in pieces? Is fragmentation allowed in these drives?
Is an LTFS (linear tape file system). The data comes from the host linearly, not in pieces or fragmented.
The data is written sequentially by file, if you're backing up files. If you're dd'ing an entire drive (aka "imaging the drive") you're also writing sequentially.
