That's a great perspective, I like that. At some level, everything because a magic black box to everyone; it's just different levels.

I have a saying/theory/whatever: There is always a point where you look at technology and consider it a "magic black box". This is where your understanding ends and it "just works". IT people need to be many, many layers deeper than the average user.
I really like this.
The question is how do I erase the magic box in an efficient way? I think forums where fact/opinion are both listed really halts the learning process. I say that as a person who has unknowingly been wrong myself.

In some ways it certainly does. But in other ways it exposes misconceptions. Look at people who learn elsewhere then post things on forums and get their ideas vetted by live logic and examination. I think that forums expose a lot that are missed otherwise.

That is a very good point.

That's how RAID 5 spread... but then kept spreading after it didn't make sense anymore... until people started questioning it on forums and people had to reevaluate and update their knowledge.

@scottalanmiller Yeah. I still see posts about it on Spiceworks every now and then. You and I were having a conversation about the merits of Raid 10 (specifically to the solution I was discussing) which is what brought me here. /memories

Someone promoted RAID 5 within the last hour, for an 84TB array believe it or not!

Have the link? This I HAVE to watch

I'll look for it. I've lost it already. Was just one guy promoting it mid-thread. Nothing too serious. But he really got into why he liked it.
-
The best part was he felt that "if you manage it well, RAID 5 is safe." Um... how do you "manage RAID 5 well?"

@scottalanmiller His response was notifications/alerts and hotspares....

I need to make some popcorn!

He also called @scottalanmiller a troll and Spiceworks Jesus

None of this can be real

Oh man, even dumber than the initial post. Hot spares for RAID 5? how dumb is this guy!?!?

And it makes it worse that he's read about what a bad idea it is and recommends it and uses it regardless and acts like he didn't know that he was putting the business at risk!

I just forked the Exablox thread to its own location.

I was going to chime and say hot/cold spares are irrelevant with OneBlox's distributed object store. We recover from a drive(s) failure without the need to have drive assets sitting passively by. After that's complete, we can recover from additional failures....all without replacing a hard drive. (Caveat: there needs to be enough capacity in the storage pool, but technically possible.)

Yeah, the idea of hot spares is very much a RAID-specific solution. Doesn't apply to object dat stores. Scale doesn't use hot spare either, just rebalances.
