Hi Ceph users
We are planning to setup a small ceph cluster, starting with 3 nodes for VM's.
I have some question about CPU and caching
We would like to start with the following config:
Supermicro X11SSI-LN4F
Intel E3-1246 v3 3.5Ghz
32GB RAM
S3500 80GB M.2 for OS
AOC-S3008L-L8e (LSI SAS3008)
4x 2TB ST2000NM0034 SAS12Gb
1x Intel 200GB S3710 for journal (via onboard SATA)
4x 1Gb for networking
Questions:
Is the CPU enough ?
I would like to run the monitoring deamon on the same host, would this be a problem ?
Optionally i would like to add an extra SSD for caching
Does write-back caching also optimize the reads ?
Do I need two SSD's per node
Kind regards,
Tom
