Question for Peter,
Curious if you’ve separated your mysql database to another host, or if your SSD’s provide plenty of IO for that many devices plus the DB?
Almost 700 devices here, with 40k interfaces and SAS raid 10 is starting not to cut it. :/
Thanks,

Just want to confirm what Markus telling.
We are running 600 devices, 25k interfaces and 20k sensors on a couple of SSDs without rrdcache.

What kind of storage do you use? I'm pretty sure just a SSD-disk with no rrdcached is the best option here.
