Hi, 

I have a pg calc question. 

https://ceph.com/pgcalc/ 

We have 45 OSD's. 
30 OSD's as SSD's and 15 as normal SATA disks. 

2 rulesets: 
ssd and sata 

We have 6 pools. 

data 
metadata 
ssd 
sata 
ssd-bench 
sata-bench 

So some pools points to the same ruleset (osd's). 
What is the best pg number per pool if data, metadata ssd and ssd-bench points 
to ssd ruleset and sata + sata-bench to sata ruleset. 

Thanks for your answer. 

Regards, 
Erik
