Hi Johannes,
Thanks for your reply.
I am naive for this, no idea how to make a configurations or where I can starts? based on the 4 options mentioned.
Hope you can expound it further if possible.
Best regards,
Mario

Hi,

you’ll have more or less four options:
- SSDs for the journals of the OSD-process (SSD must be able to perform good on synchronous writes)
- an SSD only pool for „high performance“ data
- Using SSDs for the primary copy (fast reads), can be combined with the first
- Using a cache pool with an SSD-only pool in front of the main disk-pool

That’s about 20MB/s, for (I guess) sequential writes on a disk only cluster that’s ok. But you can improve that with SSDs, but you have to choose the best option for your setup, depending on the expected workload.
greetings
Johannes
