Hi guys,
I am currently testing the performance of RBD using a cache pool and a 4/2
erasure profile pool.
I have two SSD cache servers (2 SSDs for journals, 7 SSDs for data) with
2x10Gbit bonded each and a six OSD nodes with a 10Gbit public and 10Gbit
cluster network for the erasure pool (10x3TB
Hey Nick,
Thanks for taking the time to answer my questions. Some in-line comments.

Appreciate your insights.

cluster network for the erasure pool (10x3TB without separate journal).

Thanks yet again Nick for the help and explanations. I will experiment some
more and see if I can get the slow requests further down and increase the
overall performance.

Hey guys,
Today I noticed when adding new monitors to the cluster that two OSD
servers couldn't talk to each other for some reason. I am not sure if
adding the monitors caused this issue or whether the issue was always there
but adding the monitor showed it. After removing the new monitor the
