I'll be referring in this page, to a type of SSD developed by Intel and Micron, called 3D X-Point (pronounced "crosspoint"). It's most widely sold as Intel's Optane. The Optane devices I mean are things like the 900p, 905p, and P48xx. First generation optane and some smaller ones aren't...
I've got a question about SLOG. I'm not sure if it has to be redundant. What I've read so far says, that it does not need to be redundant because if device fails, the ZIL just goes to the pool where it would be without SLOG anyways.
OK, but I never had a completely failing SSD so far. If I...
I've tried everything I can think of including synthetic benchmarks but the zil never gets used (not even a little). This is the case even when transferring files form a SSD to a local pool. Sync options haven't appeared to do anything. What else could I be missing? I'm new to ZFS and don't use...
It seems that zilstat is still broken

I googled this but I don't have the experience and certainty so I thought it's worth asking here.
I have a decent SSD (Intel P3700 NVMe) that I plan to redeploy as a ZIL. It's a lot bigger than the ZIL needs to be, and web pages make clear that many SSDs can gain phenomenal performance if they...
I just saw these on ebay and thought people on this forum might find them interesting:
Looks like a pretty hefty capacitor for...
I'm going over this guis blog https://pthree.org/2012/12/07/zfs-administration-part-iv-the-adjustable-replacement-cache/
Pretty great read and I was wondering, at the end of this post he shows that he has a 2 OCZ ssds in both mirror and stripe? - or do I read it incorrectly?
Two questions -
1) Does 'zfs receive' utilize the ZIL and therefor a SLOG if you have one?
2) I have several 16 drive (3.5") chassis that I've inherited that I'll be using for backups for VM hosts. I'll be using zfs send/rec to get the data there. Would I be better off having two 8 drive...
Hi all, I've been wandering on the forum for some hours and read a lot of posts regarding write speed, but was not able to find something to point me in the right direction.
First my build:
HP ML110 G9
Build FreeNAS-11.0-U1 (aa82cc58d)
Platform Intel(R) Xeon(R) CPU E5-2603 v4 @ 1.70GHz
ich beschäftige mich in Form eines Projekts mit Storage für eine kleine VDI.
Mein Pool beinhaltet 8x 1TB HDDs und bis zu 6 SSDs.
Ich habe meinen Pool so konfiguriert dass ich 4 512Gb EVO SSDs als L2Arc nehme
und 2 512GB EVO SSDs als ZIL. Mag vielleicht erstmal oversized sein...
Hi Guys - Long time lurker, first time poster.
Anyways looking to upgrade my NAS setup and figured I would go with ZFS and FreeNAS. Been using a Synology 1812+ for the past 5 years. Hardware RAID5/6 on Areca Controller and CentOS before that. This time I want to go with ZFS for its increased...
Ich experimentiere gerade mit FreeNAS und will es demnächst als Produktivsystem (privat) einsetzen. Folgende Konstellation ist geplant:
MB: Supermicro X11SSL
CPU: Xeon E3-1240v6
RAM: 16GB ECC-RAM (wird erweitert auf 32GB)
System: ESXi 6.5 auf USB-Stick
Fespl.: 7x WD Red 3TB für Daten...
Short simple version: I'm setting up my FreeNAS build to handle general file serving and as a ESXi VM store. I got very lucky with the ZIL, which got upgraded to a top-end Intel P3700 datacenter SSD via RMA, and now I don't know how to make best use of that device. My hardware...
