Tape is still alive, or at least in conversations and discussions

Depending on whom you talk to or ask, you will get different views and opinions, some of them stronger than others on if magnetic tape is dead or alive as a data storage medium. However an aspect of tape that is alive are the discussions by those for, against or that simply see it as one of many data storage mediums and technologies whose role is changing.

Here is a link to an a ongoing discussion over in one of the Linked In group forums (Backup & Recovery Professionals) titled About Tape and disk drives. Rest assured, there is plenty of fud and hype on both sides of the tape is dead (or alive) arguments, not very different from the disk is dead vs. SSD or cloud arguments. After all, not everything is the same in data centers, clouds and information factories.

Fwiw, I removed tape from my environment about 8 years ago, or I should say directly as some of my cloud providers may in fact be using tape in various ways that I do not see, nor do I care one way or the other as long as my data is safe, secure, protected and SLA’s are meet. Likewise, I consult and advice for organizations where tape still exists yet its role is changing, same with those using disk and cloud.

I am not ready to adopt the singular view that tape is dead yet as I know too many environments that are still using it, however agree that its role is changing, thus I am not part of the tape cheerleading camp.

On the other hand, I am a fan of using disk based data protection along with cloud in new and creative (including for my use) as part of modernizing data protection. Although I see disk as having a very bright and important future beyond what it is being used for now, at least today, I am not ready to join the chants of tape is dead either.

Does that mean I can’t decide or don’t want to pick a side? NO

It means that I do not have to nor should anyone have to choose a side, instead look at your options, what are you trying to do, how can you leverage different things, techniques and tools to maximize your return on innovation. If that means that tape is, being phased out of your organization good for you. If that means there is a new or different role for tape in your organization co-existing with disk, then good for you.

If somebody tells you that tape sucks and that you are dumb and stupid for using it without giving any informed basis for those comments then call them dumb and stupid requesting they come back when then can learn more about your environment, needs, and requirements ready to have an informed discussion on how to move forward.

Likewise, if you can make an informed value proposition on why and how to migrate to new ways of modernizing data protection without having to stoop to the tape is dead argument, or cite some research or whatever, good for you and start telling others about it.

Otoh, if you need to use fud and hype on why tape is dead, why it sucks or is bad, at least come up with some new and relevant facts, third-party research, arguments or value propositions.

Ok, nuff said.

    Speaking of disk and tape, here is a the first of a series of new posts Im doing as a guest blogger over at The Virtualization Practice site:

    Hard Disk Drives (HDD) for virtual environments (Part I)

    Hey Greg – we announced our HP StoreEver Storage tape portfolio with LTO-6 the day after your blog post – you sure had an inside track! I have a number of blog posts talking about tape (and a webinar this week on Thursday) you can find there (http://h30507.www3.hp.com/t5/Around-the-Storage-Block-Blog/bg-p/139/label-name/StoreEver).

    Here’s what I see, at least from a vendor perspective (meaning what vendors say):

    1). Vendors who don’t have tape (but offer higher cost disk-based backup and archiving) have been putting tape in the grave for 10+ years.

    2). HP and other vendors that can offer both tape and disk for backup/recovery and long-term archiving aren’t going to push customers in a single direction – tiering of backup and archive data is still entirely viable and can save a lot of money.

    Last point – I’ve seen a lot of data recently talking about some of the disk vs. tape FUD – the on that surprised me is the reliability of tape. Tape is inherently more reliable than disk and I think I’ll make that a subject of an upcoming podcast.

    Thanks Calvin for stopping by and your comments.
    Not sure what you mean by “…you sure had an inside track!” as the post was independent of your announcement, no inside scope embargo or pre-brief info involved at all!

    The info in the post is simply from being involved as opposed to waiting to hear what is going on via announcements/briefing notes. In fact I didnt know or hear anything about what you were doing until the following day when I recieved the press/media/analyst announcement briefing material via email from your HP pr folks.

    However to your point, Indeed there is plenty of hype and fud being tossed by both the pro tape and pro disk camps for various reasons or objectives. With some of it Im not sure whats more interesting, that some of the people throwing the hype and fud believe it, or that some who hear it dont know its hype or fud ;)…

    I used to fix tape drives disks and printers for 14 years back in my days at StorageTek (see my pictures on http://www.jdtools.ca/about

    Tape always been the underdog IT and does not have good press mostly because it requires daily manual control and handling. But if you are doing a good job tracking your tape drives and media errors you have a good cheap storage solution that can save you job. It is not that hard either. Just a constant monitoring. Something admin rarely do even with disk capacity and performance.

    In other hand disk solution are popular because they solve one of the biggest nightmare of tape…speed. Because modern tape drives, such as LTO-6 and T10000C, required huge “sustain” bandwidth, backup are slow caused by shoeshine effect. The shoeshine effect kill tape performance by half and cause media damage in a long run. Back in 80′s even 12 inch tape drives where shoe shining with 1.5MB/sec native speed. Back then they were start-stop tape drives. Vacuumed tape path was used to avoid tape stretching and keeping tape tension on the head.

    I rely like an architecture where disk front-end tape (D2D2T). It simply solve the shoeshine effect and allow backup to run error free.

    So bottom line, tape is more likely faster than disk during backup and disk solve the issue by have m/s retry versus seconds to minutes to reposition the head in front of the right block.
