Slideshow explaining VDev, zpool, ZIL and L2ARC and other newbie mistakes!

I've put together a Powerpoint presentation(and PDF) that gives some useful info for newbies to FreeNAS. I decided to create this slideshow because in the last 5 months I've been on this forum I've seen a lot of people confused about vdevs, zpools, zils, l2arcs, etc. Hopefully we can put to rest a lot of the confusion once and for all.

We get a large amount of duplicate threads with the same questions being asked every other day. Personally, we get them so often I decided to stop answering them and decided a better use of my time would be to create this presentation. I literally read every thread and every post that goes on the forum. So if I don't answer either the answer is in the thread or the answer is found in this presentation or FreeNAS manual. Answering every 3rd thread with "Consult the manual" gets a little old after a while and I have better uses for my time.

This presentation also contains a lot of information that is explained in a little more detail for new users. It includes many common errors newbies make and can save you some heartache. If you are brand new to FreeBSD, I recommend reading the manual cover to cover. There are a lot of recommendations throughout the manual, and they are typically there because they are an error trap for many people.

I've saved this in Powerpoint because I have some animations in the slideshow. I'm not sure what other formats would work. If you would like this in another format that supports animations please let me know and I'll see what I can do. Currently I provide this in a powerpoint presentation and PDF. The PDF has no animations therefore the Powerpoint is preferred.

I'll try to keep it updated as necessary. If this presentation helps you please "like" it so others can see that it really is worth the time to read!

A newer document, focused on ZFS, is also available in the Resources section:

Loved the power point, lots of great information. I am working on a build list now. :)

Keep in mind that you can save significantly on the cost of gear if you are willing to pick used items from eBay.

FreeNAS does not need the very latest hardware, in fact, sometimes the very latest hardware is not yet fully supported.

Hi there, does those attachment unavailable to view any more?
Someone deleted the files, which should not have happened, but it did. I restored them and you should be able to access them now.

Hello. This guide was last updated in 2016. Is there a more recent guide available? I am asking because I understand that ZFS and FreeNAS are constantly changing and I am now confronted with managing a older server that currently runs Windows Server 2012 which I plan to replace with FreeNAS. I have never used FreeNAS or ZFS.

Despite the age of this guide, many of the basics have not changed that much, so it is a good foundation of knowledge.

Agreed that this guide/presentation and the IXSystems training videos are actually SUPER helpful. I think the videos move a little too quickly and you don't have enough time to let things sink in, but they deliver the content. For me, once I finished drinking from that firehose, Cyberjock's presentation really bottom-lined everything that was important. Still have a long way to go but I'm confident in my approach now. :)
