Should We Ever Talk About JBODs

... Because a disk enclosure can contain a bunch of disks that are already raided by some means.
If you're supplied something that already has some means of RAID applied at the box level, I personally wouldn't call that a simple disk enclosure. It's now an appliance, not a disk enclosure.

Okay, what about this view...
What would you have called this before the term JBOD?: http://dataonstorage.com/dns-jbod-enclosure/dns-2608-4u-32-bay-12gbps-sas-enterprise-jbod-storage-enclosure.html
If you say "disk enclosure", then you can't use that as easily as JBOD. Because a disk enclosure can contain a bunch of disks that are already raided by some means. Therefore, you can't say just disk enclosure. JBOD specifically implies a disk enclosure that is not raided by anything.
And what happens the moment you apply RAID or something else to it? Is it suddenly no longer JBOD?
That's the problem, it gets confusing at that point.

Right, I can't think of any case where disk enclosure != JBOD enclosure. I guess if we are referring to many enclosures of varying types? Maybe?

Every time in Microsoft documentation they use the word JBOD, it's used correctly that I've seen. It's used to mean one thing, always. It's never used to mean anything other than this: http://dataonstorage.com/dns-jbod-enclosure/dns-2608-4u-32-bay-12gbps-sas-enterprise-jbod-storage-enclosure.html
Is it? So with SS for example, it won't function with actual JBODs, but only JBOD enclosures? There is no way to use it with local disks? How does it know?
It's all in the context of which it's being used. I've never seen JBOD used officially, in a context that doesn't imply a JBOD enclosure.
I suppose you could say, "set up your servers internal storage in a JBOD configuration". Or you could say "hook up your server to a JBOD". Or even "I just dropped my JBOD enclosure"
Honestly, all are correct, and I don't see any issue what so ever with any. It doesn't make me any less knowledgeable or show that I can't do my job less well than someone else who avoids the term.
-
I guess one of the things for me is, I've never used the term and have not lacked for expressive terminology. And it isn't like I don't have to talk about disks on a regular basis.

I take that back. I have in a "configuration" sense.

For example, I don't consider DROBO a disk enclosure, it's an appliance. The device itself applies whatever RAID level I want to the disks, then there is an interface to that storage (either block level or share level).

The problem is, and we've proven this I feel beyond any doubt, is that if you use the term you are no longer able to reliable convey your meaning to other IT pros. Certainly not ones in this thread, ML, SW or at MS. All of them have differing, conflicting ideas from how you just used it.
The majority of "JBOD discussions" if you will, that I have seen, involve "just a bunch of disks" in a server, not in an enclosure. So the majority that I see would find this conversation very confusing because they are using the accepted Wikipedia definition, not the one that implies an enclosure.

As just a random phrase with no official product or sponsor, I'm not sure any use is more or less official than any other. Wikipedia would be the closest to official that you could get, or maybe the OED if they covered that sort of thing.

LOL - so the people who required JBOD didn't care about their data I take it?

Microsoft lists it as a requirement.

Okay, so I have taken a look at the history of "JBOD" on Wikipedia... take a look at it, just for laughs. Click on the history tab and change edits to 500, then search JBOD.. highlight them if using firefox to find them easier. Look at the bigger edits. To me it's all a joke, now.
The more I look at the meaning of "JBOD" from "word authority" sites like Wikipedia and others, and various IT pros and such, the more I feel that the word "JBOD" is just some randomly made acronym with no real value. It seems to be just a big marketing term, and also a literal term used to mean an actual bunch of disks in the sense that there's some disks not yet in a RAID, and that are shown as pass-through disks if there's a hardware raid card present.
-
I got the main idea of how it is used... JBOD enclosure, you need a JBOD attached to a server, etc... I get JBOD configuration to mean disks with pass-through in the presence of a hardware RAID card, or exposed as individual drives.
But I'm going to go ahead and pretend the term or acronym JBOD does not exist from now on.

I've literally never heard any vendor use the term in marketing, white papers, in person... nothing. I've never heard the term outside of SMB IT pros talking about... random things.

Yes, that's my thought. Someone started using it to sound cool or something. It's somehow become oddly associated with Microsoft recently, too. My guess is some yahoo inside MS started using it and it became some weird cultural thing.

That's the conclusion that I had reached that prompted me to start this thread. I saw like five different usages in five posts and none made any sense to me. Then I started trying to closely define JBOD and couldn't come up with how to really do it right.
Someone actually started the thread looking for RAID 10 JBOD. And then wanted RAIN on top of that. About as anti-JBOD as you could imagine.

Oh you saw a MS requirement only after making that post? Where did you see the MS requirement?
