If you are just playing around, you could roll everything onto a single server. Or, if you wanted, put the MON and OSD on a single server and the radosgw on a different server. You can accomplish this in a virtual machine if you don't have all the hardware you would like to test with. > -----Original Message----- > From: ceph-users-bounces@xxxxxxxxxxxxxx [mailto:ceph-users- > bounces@xxxxxxxxxxxxxx] On Behalf Of Guang > Sent: Monday, September 16, 2013 6:14 AM > To: ceph-users@xxxxxxxxxxxxxx; Ceph Development > Subject: Deploy a Ceph cluster to play around with > > Hello ceph-users, ceph-devel, > Nice to meet you in the community! > Today I tried to deploy a Ceph cluster to play around with the API, and during > the deployment, i have a couple of questions which may need you help: > 1) How many hosts do I need if I want to deploy a cluster with RadosGW (so > that I can try with the S3 API)?
