I have got a pair of Intel Optane 800P and updated my pdf with benchmarks
at http://napp-it.org/doc/downloads/optane_slog_pool_performane.pdf
Some important results especially for the critical sync write vs async write value
that is the most important value for databases, VM storage or even a filer when you want
to ensure a write behaviour where a crash during writes does not result in a dataloss
of commited writes.
Benchmark with a Filebench singlestreamwrite
Single Optane 32G (basic pool) on OmniOS
not so bad but far below the bigger models 800P or 900P especially on async values
Single Optane 800P-118 (basic pool) on OmniOS
Single 900P-280 (basic pool) on OmniOS
A single 900P is 3x as fast than the 800P
Dual 800P-118 (Raid-0) on OmniOS
A single 900P is much faster than a Raid-0 of two 800P
Dual 800P-118 (Raid-0) on Solaris 11.4
Solaris is faster than OmniOS/ OpenZFS
Dual 900P-280 (Raid-0) on OmniOS
Dual 900P-280 (Raid-0) on Solaris 11.4
Solaris is faster than OmniOS/ OpenZFS
16 x SSD Sandisk Extreme Pro 960 in Raid-0 without Slog
69 MB/s sync write performance, good for an 1G network but far below the
async value of 1759 MB/s
16 x SSD Sandisk Extreme Pro 960 in Raid-0 with an Optane 800P Slog
There is a hefty improvement with an Optane Slog and even a massive SSD Raid-0 pool
as the SSDs (even the Sandisk extreme) are much slower than a single Optane 800P
16 x SSD Sandisk Extreme Pro 960 in Raid-0 with an Optane 900P Slog
The difference from 800P to 900P is minimal when used as an Slog for an SSD pool.
Overall:
If you need high sync write values
1.) use an Optane 800p 58/118 GB (care about the 365 TBW endurance)
2.) use a better Optane 900P/905P
or the enterprise 4800X (not faster but with guaranteed powerloss protection)
3.) there is no option three
Intel Optane is a game changer technology
