EMC Elastic Cloud Storage (ECS) is a new EMC product to provide object storage (Amazon S3 and OpenStack Swift APIs).

EMC has just released ECS Community Edition installer on Github that allows customers to try and use it on standard X86 hardware with Centos 7.

The goal of this post is to install and configure ECS on Gandi Cloud VMs :

• EMC ECS is Java based software
• ECS image will run into Docker container on Centos 7
• ECS image is available in EMCCorp docker registry
• GitHub repository is storing ECS installer (python), I don't know if docker image is open-source too.

So, let's go installing EMC ECS on Gandi VMs ;)

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 ?).
