What did you mean by “using multiple zpools”? … one raidz2 per pool?

Misspoke meant vdevs lol sorry. Each vdev is raidz2 across some different pools

A Steam cache setup guide or video would be great. I’ve been thinking about getting one running for some time now.


if I heard you correctly…

you only created one 60G partition on the optane for zil and you created another two partitions; one for cache and other for…?
Based on screenshot

I just came to wag my E-Peen at Wendell.

The middle one has a typo and didn’t create anything

I have more than one storage server you know :wink:


Now your just braggin :slight_smile:


lol, Well my home rack will give you the cringe.


I have the problem where I have too many hard drives for the case that I use for my storage server.

Gcs8, needs more RGB.

Cool vid wendell!

I’m running below with Proxmox:

Chassis: Supermicro CSE-826TQ-R800LPB
Backplane: BPN-SAS-826TQ 12 3.5" SAS / SATA Direct Attached Backplane 6GBPS SES II
CPU: 2 x Intel Xeon E5645 2.4Ghz Six Core
OS DIsks: 2x Crucial MX300 in ZFS mirror
non-OS Disks: 12x WD Red 4TB in ZFS RAID10
Have been thinking about adding a ZIL or L2ARC but performance is OK for now, mostly idle.
VMs for pihole, aptmirror, ansible, onlyoffice, nextcloud, jitsi, plex, pxeboot, wiki and a few others
Hosting some silly things like:
Am slowly poking away at automated installation through pxeboot.
I uh also am in need of a noise dampening server rack enclosure something, it’s currently sitting in my attic on some carton boxes with fans in desktop mode, not too noisy until it gets busy, will take off then.
Have looked at apc netshelter mini and equivalents but they’re expensive, I could try to DIY something myself?

Am interested to see how you’d deploy the caches for Steam/Blizzard/Origin downloads.

I would love to know what ecc memory kit @wendell used in this build. I am also using the X370 Taichi but ASRock’s memory QVL is sparse on ecc kits - expecially for 16gb dimms. Thanks for the help!

There was a screen shot of it at the beginning

@Wendell Great video! I love your hardware/ZFS/GODMODE stuff.

How did you get the steamcache at 10Gbps? I might have blacked out due to the awesomness of the video :frowning: , was it a network component?

You guys really inspired me in the original video to get my own steamcache going, but right now my Internet speed is faster than my LAN connection lol. Getting 10Gbps would be awesome. I actually got the steamcache going with Docker containers. It was too easy, I didn’t think it worked :exploding_head:

lol just some dnshackery + docker and thats it. LITERALLY IT
they even have an example script to show you what the cache is doing. be warned however you have some fiddling to do to get the blizzard/etc cache to work correctly

r/cablefail. NOW.

Optane sounds really interesting now in it’s SAS 2.5’’ form factor. Might consider it for my Threadripper build, since the endurance and random IOPS is better on Optane.


The whole house is RGB from the Lifx bulbs through the house.

I don’t get paid to make things pritty at home, only at work.
