I suggest reading the forum threads regarding ZFS, SLOG\ZIL, L2ARC.I SO wish I understood what was being said here.
Were those specs about the 900 and 905p ... and maybe in RAID or something
- where it said 100GB specs ...and then
- 200GB specs ..?
or is that saying that the performance of a larger capacity drive just doubles the stats!??
Very confusing.
What IS the difference between the 905p / p4800x / p4801x ...?
Were people talking about using them in a raid of 4 drives!? Geesh.
How does it work..?
Let's say I'm writing 420GB of data ... and I have a 375GB Optane + 48GB of RAM ...
Does that mean that no matter HOW slow the spinning drives are ... I could write 423GB (obviously a little less bc of overhead and formatted capacity, MiB vs MB, etc) ... but between the DRAM + Optane, they could literally hold 100% of the data being written to buffer the performance..? Is that literally how it works..?
Is that how you choose the size of an Optane sort of..? And then I'd need a
• ZIL
• L2arc

Thanks!
Read the Intel Spec sheet on the Optane 900p, 905p and 4800x\4801x and then re-read this thread.
It's a LOT to try to take in hardware specifications and understanding ZFS all at once
The forum (and some main site posts) cover these topics very well in my opnion and since they're a common topic they're discussed in different ways in different threads.
We use optane for high performance storage and SLOG device as well.
