HA Ceph object cluster : OpenSVC Flex, Gandi & RR-DNS
The goal of this post is to provide small footprint object storage CEPH cluster with high resiliency and no SPOF. We will build it with OpenSVC, Ceph, Gandi and Puppet.
Thanks to OVH HA Load Balancing usecases available on ovh.com.
CEPH software (MON and OSD) has no SPOF but RADOSGW can be one if you install only one instance. We can manage several instances and balance S3 or Openstack Swift requests with RR DNS (easy way).
I will explain how to deploy CEPH cluster with 5 Gandi small VM :
- 1 VCPU
- 512MB of RAM
- 2x5GB disks
I will have a look on several Object and/or ScaleOut storage solution that can be installed on Gandi VMs (ScaleIO, Scality ?, Hedvig ?).
