Can we install Ceph in a single node (both Monitor & OSD). You can, but I would only recommend it for testing/experimentation. No production (or even pre-production) cluster with any meaningful amount of use should be a single node. > 2. What should be the minimum hardware requirement of the server (CPU, > Memory, NIC etc) There is no real "minimum" to run Ceph, it's all about what your workload will look like and what kind of performance you need. We have seen Ceph run on Raspberry Pis. I would suggest taking a look at some of the hardware guides and reference architectures available though. A few examples would be: http://ceph.com/docs/master/start/hardware-recommendations/ https://engage.redhat.com/inktank-hardware-selection-guide-s-201409080912 https://engage.redhat.com/inktank-ceph-storage-for-dell-s-201409081132 http://karan-mj.blogspot.com/2014/01/zero-to-hero-guide-for-ceph-cluster.html http://www.supermicro.com/solutions/datasheet_Ceph.pdf > 3.

Since a single node isn't really demonstrating a realistic Ceph install we decided that a multi-node install was more effective, which is what you'll see in our docs. However, if you'd like a contained Ceph install to experiment with you can try the latest qemu advent calendar image ( http://www.qemu-advent-calendar.org/#day-18 ) or try the installation instructions from an older version of the doc: http://ceph.com/docs/v0.67.9/start/quick-start/ While that doc is quite outdated I'm sure you can see how to adapt the more recent install guide to that procedure if you're really set on doing a single node install. I would probably just use the qemu image for experimentation and then move to the multi node install. Hope that helps!
