Ryan should start doing Level099Techs, where he has a couple drinks and tries to explain things to tech enthusiasts who are less-knowledgeable..

[valdius]

I don't understand a single thing.
I love these videos.
You show complicated terms on the screen and this is enough for me to find information.
Thank you so much.

Love how cause of AMD I see a dual 28 core cpu system and go "is that it?"

[johnbrooks]

I love the podcast but this is the cool stuff that comes around every once in a while. Very cool.

[ewilliams]

As an admin for an EMC Compellent SAN that's about to double in size, I really need a "UHH let's not" video.

[JoeGrimer]

Man this is one of the most densely packed 17 minute videos... thanks!

Modern Software Defined Storage on Truly Ancient Hardware.
I backup my Ryzen desktop with Ubuntu on ZFS to a Pentium 4 with FreeBSD on ZFS. Only FreeBSD supports 32-bits for ZFS :) My Back-up Server is a build based on the remains of a 2003 HP D530 SFF with a Pentium 4 HT (3.0 GHz), 1.25 GB DDR (400 MHz) and 4 leftover HDDs together 1.2 TB (2 x 2.5" SATA-1 and 2 x 3.5" IDE). Both systems are protected against the frequent power-fails by an Avtek 1200W Surge Protector.

Total Server Costs: DOP 1000 ($20) for an 3rd-hand Compaq Evo Tower and a new locally bought 500W iTech power-supply, coincidentally coming with 2 SATA and 2 Molex connectors. The Case-sticker says: "Intel Inside Pentium 4" and "Designed for Windows 2000 Professional / Windows 98".

The system runs 32-bits FreeBSD 12.1 on ZFS with XFCE, XRDP and Conky and it is powered on for <1 hour/week, so it ages for say ~1 week/year :). The system is connected to a 1 Gbps network, but in practice it runs at ~200 Mbps, due to a CPU load of 95% on one one the HW threads of the Pentium 4 HT (3.0 GHz). The load is caused by the network process and not by ZFS.

I like how when you mouse over the thumbnail the preview is Wendell magically waving his hand over the hard drive racks, lol.

[erisdiscordia]

Would have been cool to also include a quick look at Ceph or gluster. Might alao be an interesting video in and of itself, looking at different software defined storage solutions, comparing them in regards to features and performance.

[agenericaccount]

Every time a tech tuber mentions RAID I have no idea what they are talking about because I am not into that world. Tucking into this with zeal, thanks for publishing it.

[gracefullyinsane]

I'd love to see your thoughts on Proxmox/Ceph/HA and where it fits in with ZFS and LVM or so.

[itsdeonlol]

Man, I love when Wendell shows us some server stuff!!!

[steven]

a ceph / gluster video would go well with this. this covers some raid in a box, then you can have raid across multiple boxes as you step up in complexity/availability.

[tracyrreed]

If you are really interested in software defined storage you have to look at Ceph. It's awesome. I've been using it for a few years and I am amazed.

Dude, you got me from doing a dell r710 server for hardware raid to software raid.

I put 3 years into the r710 and never got it working right. I put 3 hours into truenas with consumer hardware and its been performing GREAT even if it drops out sometimes.

[trumanhw]

Please please PLEASE please PLEASE Wendell ... PLEASE do a video talking about the advantages of LSI Disk Shelves ...
And -- perhaps do an "Ask me EVERYTHING" -- A Troubleshooting video dedicated to making ZFS systems work optimally.

[Stephen-whvl]

These are my favorite kind of videos on this channel.

[pianoplayerkey]

"ZFS is gonna be amazing when it will properly support having mixed speeds of disks" ... I'd also like to see it support some other things that I've heard (from Linus) that UnRAID supports - adding different drives to an array individually, *AND* if more drives than your parity / redundancy fails, you ONLY lose the data on those drives, NOT ALL your data.

[evanjrowley]

Big fan of ZFS. Glad to see you covering it here in detail. I hope something as good comes along with a license that's better for the Linux kernel. BcacheFS sounds promising, but I think it's still got a long way to go. One wonders if HAMMER2 could compete with ZFS and if it would ever ported to Linux.

[swayne]

Love ZFS been using it for a few years now on my home NAS set up.
